Webinar: Genetic Testing in Epilepsy: Understanding Results and their Impact on Care

Genetic testing has increased our understanding of the genetic causes of epilepsy exponentially in the past two decades, specifically helping researchers identify many genes responsible for rare childhood epilepsies. Recent studies found that in addition to providing patients and their loved ones some relief in ending their often too long diagnostic odyssey, genetic testing can enable tailored treatment options and can help with long-term outcome prediction, and family risk and planning decisions. However, there are still many individuals who lack a genetic diagnosis, including adults who may not even be aware that they could benefit from genetic testing.

This webinar will help viewers understand who may want to discuss genetic testing with their doctor and then will explore the following topics following genetic testing:

  • How to read a genetic testing report.
  • What are the different types of genetic results (or variants)?
  • What are the differences between benign, pathogenic, and uncertain variants?
  • What to do after receiving a genetic diagnosis.
  • How do these results impact an epilepsy treatment plan moving forward?

This webinar is the first of two webinars in March that address CURE Epilepsy’s ongoing focus on epilepsy genetics and research in the rare epilepsies. Our second webinar will be presented by Drs. Gemma Carvill, PhD and Elizabeth Gerard, MD from Northwestern University focus on genetic testing in adults and will be held on March 22, 2024. Click here to register for the March 22 webinar.

Webinar: Prioritizing the Role of People with Lived Experience in Epilepsy Research

The role of people with epilepsy and their support system in research has been evolving over the past couple decades as research and the corresponding care and treatment of epilepsy become more patient-centric. Involvement of people with lived experience early in the research process helps ensure that healthcare professionals treat epilepsy in a more holistic manner, not only by alleviating the impact of seizures and their debilitating side effects, but also by recognizing that everyone’s epilepsy journey is unique.

In this webinar, attendees will learn specifically about the importance and impact of people with lived experience in research of post-traumatic epilepsy (PTE). Attendees will hear about the Congressionally Directed Medical Research Programs (CDMRP), a Congressional appropriation that fills research gaps by funding high impact, high risk and high gain projects that other agencies may not fund, as well as the CDMRP’s commitment to community engagement. Additionally, people with lived experience who are deeply involved in the CURE Epilepsy mission will share their unique experiences in helping move PTE research forward.

About the Speakers:

Melissa Miller, PhD, is a Health Sciences Program Manager with the United States Department of Defense. Dr. Miller is a biomedical science administrator with an innate sense of urgency to support research that accelerates clinical application of disease interventions. She oversees the Epilepsy Research Program (ERP) within the CDMRP and engages stakeholders across different research domains to identify and fund projects with real promise to improve the quality of life for those impacted by epilepsy. 

Jack Somers is a Captain in the United States Marines Corp (Ret.) and who served his country in Afghanistan. Jack serves on the Steering Committee of CURE Epilepsy’s latest project in PTE research. 

Patty Horan has been a long-time supporter of CURE Epilepsy and currently serves as a lived experience reviewer for the CDMRP ERP. Patty’s husband, Pat Horan, suffered a traumatic brain injury in 2007 and overcame his grave diagnosis and the devastating consequences of the corresponding PTE and now is nearly 10 years seizure-free.


Q&A

Because science isn’t your background. This is all new to you. So why did you want to participate in research as a person with lived experience? What compelled you?

Jack Somers: I think the most important part to me was to serve. Ultimately, that brings me the most amount of joy. I hope that’s not a selfish response, but it is. Serving the community is the utmost importance to me. And given I do have experience, and I have so much experience over the last 14 years, the opportunity to give back, and hopefully, if it’s helping one person who has this, or helping one mother, father, wife, husband, son, daughter, anyone, a friend, who is a loved one of somebody who has PTE, then that’s, then sign me up. Anything I can do from my position is worth it. And so, service is everything to me. And so, anything I can do from my position is an obligation of mine.

 

Patty Horan: I guess I agree with Jack, and the fact that I’ve seen so much suffering in the veteran community is unbelievable. And if there’s anything that I can do to reduce the suffering of people in this community, they deserve it all. I mean, they deserve our attention, our focus, and anything we can do to relieve some of what they’re going through is worth it. This war is awful. But I feel like this contributes to not just veterans, but the society as a whole. Because we’re learning how to better take care of our brains, and everyone’s got a brain. And I think that it’s just a really important mission.

And I will say, I am not a scientist at all, I have a business background. And it’s very scary at first to get involved in the research. I have a little selfish reason to, just to be engaged with all these brilliant scientists, that actually can give me a better understanding of how to help my husband, how to support him. And understanding of what the broader picture of epilepsy looks like, and what’s happening out there, as far as access to care, and just the latest and greatest medications, and what’s going on in the clinics.

It is daunting without having a science background to step into a role like yours, where you are discussing with the science, with well-established researchers. What were your greatest concerns when thinking about this, when you were engaged with this? And how did you overcome those concerns?

Patty Horan: I think in the beginning it was really, it’s a totally different language. It’s like walking to a foreign country, going into like, what are they saying?

So the good thing about the ERP is, you do get some time. Each person is given five projects to evaluate, and you get a couple of weeks, look over all of these. You do have to present them and speak the language, but you have a co-presenter. So if you mess up or if you didn’t get it quite right, you have somebody else to swoop in and fix it up a little bit. But the whole panel discusses everything later too, so you’re not alone.

And I think a little of it was just ignorance, because with the first panel I sat on, I was very overwhelmed. On the first break, I went outside, and I was like, “What am I here for?” But people were so gracious, they were so nice. They were so thrilled that I was there. They felt like they thought that my opinions were valuable, which was amazing, because these are some of the smartest people in the country. So it was very scary at first. And I fumbled through presenting probably the poor researchers that got me. But I did it. And every year it gets easier, and I understand the brain a little bit more. And I’ve made some great, I’ve met some great people with CURE, and just the people on the panel are just the best people. And Melissa, and it’s been overall, a great experience.

Jack Somers: I mean, similarly to Patty, I came into it with, I would say, I was a little naive, but very excited to join this group. I didn’t know a whole lot about it, but I was okay with that. I just wanted to serve and give back, and if they were willing to let me join, that was enough. I was just so excited that they were willing to let me join.

It was really the first advisors call that, like Patty, I was just blown away by they’re going through their different milestones and what have you, and the verbiage, all of the scientific research that they had done. And I just didn’t know the level of expertise that these folks had, and I didn’t understand a lot of it, but conceptually I could get it. And so, in order to overcome it, I kind of just used that old, the acronym, keep it simple, stupid.

But I just had KISS, and I just said that the best way that I can overcome this is to just keep it simple. And when I did that, I just listened and I kept it simple, and all of a sudden, I understood what they were talking about. And it was incredible, because I learned that all of these folks, who just like Patty said, some of the most brilliant neuroscientists, and epileptologists, and folks in the world, amazing. At Cambridge, at Texas Tech, at UCA, research groups, they are trying to solve the problem that I have. And they could do whatever they’d like, but there they are, and they’re passionate about it, and they’re working on this all the time.

And it actually, it almost brought me to tears. Because I said, “Why are they doing this? Why are they working on this problem?” They could do anything in the world, and they’re trying to solve the problem. They’re trying to answer the questions that I’ve been trying to answer, and keeping it simple. Let me learn. Let me figure out just what they were trying to do. And so, I then didn’t have to worry too much about all the words that they were using. I just got to listen to generally what they were trying to do, and it blew me away. It still does, every single time I listen to them.

What do you feel is the value in sharing your voice? And what do you hope your participation achieves in doing this? So what’s to the value, and what do you hope the outcomes will be?

Jack Somers: I hope that I can use my experience to give back and help one person. I hope that I can serve again. I hope that I refuse to let my experiences be lost in translation, or be just mine. I refuse to let them go to waste.

And so, my hope is that they get leveraged, is that they’re used in ways that we are just learning how to use them, and how they were used five years ago or 10 years ago is actually just the beginning. And that we learn how to use my experiences more and more, and in more efficient, more effective ways as time goes on. That’s my goal.

Patty Horan: Well, a little bit more support for caregivers and the families. So the VA, the Veterans Administration, they need concrete evidence of what’s happening in our households. They don’t necessarily understand the toll of epilepsy in a household, on a life, especially uncontrolled epilepsy. So I feel like I contributed, at least to start looking at quality of life studies.

We have some of those in our portfolio, and I feel like I push for that. And I’m hoping that the data from those studies will be concrete evidence for the VA to actually compensate these families better, that have epilepsy. They will give them better services, better access to care, and also, home health benefits. Because some of them, and we were at this point in the beginning where I couldn’t leave Pat alone for five minutes; but we didn’t qualify for any of those services, because he’s not injured enough, or the epilepsy didn’t qualify him. So it’s interesting. So I’m hoping that out of with my voice, the value will become, will be that veterans are better supported with epilepsy by the Veterans Administration, and there’s a better understanding of the daily life.

Dr. Miller, what are your hopes and visions for the future of lived experience participation, and how we go back to how can people get involved?

Dr. Miller: So I think my greatest hope for the near future is for more researchers and people with lived experience to have the conversations that we were just having. It’s so important to have opportunities for these conversations, to force opportunities for these conversations, because without them, the researchers are doing their best, but they are not the experts in your experiences. And we need you to tell them, and guide them into what is the most important and impactful questions to be researching for policy change, for care change, for overall change. And that’s what I hope really will impact the future.

And the way that people can get involved with the ERP is just going to the CDMRP website. We have a big banner on our website that says, “Get involved.” And if people are interested in reviewing for us, in consulting on projects, let us know. We can help connect you to the necessary people. I’m sure, Laura, that your organization also has opportunities. I think there’s a lot of opportunities, and we just need people, and their generosity of time to volunteer, and we can make a really great impact in this field.

Webinar: Surgical Treatment Options as Tools to Reduce the Risk of Mortality in Epilepsy

The pediatric epilepsy journey can be challenging and scary. Surgery has been less utilized but research has shown that it can be an effective treatment option, especially for those living with drug-resistant epilepsy. Surgery can reduce seizure frequency and lessen the risk of seizure-related death.

While surgery might not be an option for every patient, it is important to advocate for timely, comprehensive surgical evaluation for all people struggling with epilepsy and reduce the known disparities in access to surgical treatment options.

In this webinar, we will discuss how surgery is one of the tools available to treat epilepsy and why having a surgical evaluation is important. Attendees will also learn about how different treatment approaches can improve survival and contribute to improved healthcare outcomes.

This webinar is conducted in partnership with Partners Against Mortality in Epilepsy (PAME). The mission of PAME is to convene, educate and inspire all stakeholders – from the bereaved to those living with epilepsy, to health care professionals, advocates, clinical and basic scientists, and death investigators – to promote understanding and drive prevention of epilepsy-related mortality.

About the Speaker:
Sandi Lam, MD, MBA is the Division Chief of Pediatric Neurosurgery at the Ann and Robert H. Lurie Children’s Hospital. She serves as a Professor and Vice Chair in the Department of Neurosurgery at Northwestern University Feinberg School of Medicine in Chicago, IL.

Dr. Lam’s clinical focus encompasses pediatric epilepsy surgery and cerebrovascular surgery with expertise in surgical innovation, neuroendoscopy, minimally invasive surgical techniques, and development of multidisciplinary patient-centered clinical programs.


Q&A with Sandi Lam, MD, MBA

Is it an option for drug-resistant patients who have seizures as a result of FIRES? And perhaps you can explain FIRES in NORSE that are triggered across many parts of the brain. And similarly, is it helpful in the case of generalized seizures?

That’s a great question because these are very, very challenging diagnoses. So I would say from a traditional surgery standpoint, it is kind of the most straightforward when there is one area of the brain causing seizures and we can do surgery to remove that area. So that is kind of the most straightforward. And I had mentioned that we need to tailor epilepsy surgery options to the patient. And some are much more complex.

And the scenarios that you talk about, I mean generalized seizures or FIRES are really much more complex, but we actually have more options than when I first entered the field, which is we’re looking for this lesion, the one guilty area, and removing the guilty area that’s causing the seizures. And now we have neuromodulation, so vagus nerve stimulation, which is kind of a more broad way of stimulating the vagus nerve with broad projections to the brain to really kind of try to tell it to calm down.

But now we have other ways with brain stimulation, having deeper either targeted ways when we know that there’s a certain area we can put the electrodes there to do stimulation in a targeted area. Or we can actually have thalamic stimulation, which actually tries to help the whole network. And we really don’t, in those scenarios, we don’t know one area where the seizures are coming from.

It’s actually a more kind of generalized epilepsy where we’re actually targeting deep targets in the brain to actually tell the entire brain to have neuromodulation effects. So patients were not candidates for epilepsy surgery 20 years ago, or even 10 years ago or maybe even five years ago. Our thinking and our ability to do these surgeries safely and use these technologies more effectively is evolving and we’re getting better and better and we’re learning together.

At what age can you be a candidate for DBS or RNS? So deep brain stimulation or neuromodulation responsible?

From my standpoint, we don’t give up. We are always looking for is there something that we’re missing or something more that we haven’t tried or something that we haven’t thought of that could really be, that we can think of. Do we have more tools in our toolbox? So surgery is a tool, and we’ve thought about different types of surgery for patients who are even the youngest patients.

So when you think about a DBS, a deep brain stimulator or an RNS, a responsive neurostimulator, technically the US FDA approval is actually for adults, for patients 18 years old and above. We have actually implanted these device in children and even school aged children or a little bit younger. So while the companies will have to kind of stick to compliance and regulatory approvals, there are just human factors.

Where we tailor the treatment that we give to patients in a way where we decide as a whole team along with the family, if we think that there is a good chance of this helping have seizure control, then we actually consider it all together. So from a care team standpoint, there’s good precedent that at my center and actually multiple specialized centers in the country, we are doing cranial stimulation for children.

What is the frequency of DBS and RNS now? How common is it? Is it still considered exploratory or new?

That’s a good question. And I guess it depends on who you ask, right? So it is relatively new, but it has been used for… I guess when you look at the trials and onward, I would say I have seen data that’s at five years and 10 years. I would not call it experimental at this point because there have been trials and studies that are ongoing as well. I would say it would depend on the patient and the family and also your care team.

So I think that the patient and family have to be comfortable with their care team, and there has to be that trust. And also the care team has to be comfortable with what they’re offering. So they have to have that level of experience with the treatments that they’re offering. So it really is a combination of factors, but at a place that is really thinking about being innovative and really just not giving up and not taking, we don’t know or no for an answer.

And having that hope and curiosity to see are there things that we can do to help patients? That’s actually how we get better. And as I told you, when I first trained in this field and when I first started my practice, a lot of these were not actually even available. And now that they’re available, I’ve been lucky to be part of teams and centers that have been among the first to apply these technologies such as laser ablation or putting in responsive neurostimulation into children and doing endoscopic epilepsy surgeries.

And now we actually have quite an accumulated experience where my partners and I probably have one of the largest experiences among pediatric centers. So there is a certain level of comfort and experience to understand what are the tools in our toolbox. We don’t want to offer a tool that we don’t have, and we want to offer the tools that we know, right? That we know what the result is going to be and be able to really look you in the eye and work with families and say, you know what?

I believe this is going to help. And I know that in my experience I can say that I can do this safely, and I really have that hope of being able to help you. And we need the whole team to do this, and we need to be able to make those choices together.

How long did it take for RJ to recover?

RJ was at Lurie’s for one week and then we went straight over to inpatient rehab at Shirley Ryan for exactly 30 days and then we were home. We did intense PT, OT, and speech three days a week for three hours, one hour each section. And that was for about six months or so. And then we graduated to outpatient PT, OT and speech. And I would definitely say just a word of advice to those who are intense physical therapy, occupational therapy and speech therapy.

Start looking in advance because I know where I’m from, it was a long waiting list. However, like how Dr. Lam said that advocating for your child, I advocated heavily. I searched high and low, I put him on multiple waiting lists and it was first come first serve.

Webinar: Epilepsy with Eyelid Myoclonia (EEM), Formerly Known as Jeavons Syndrome: Diagnosis and Treatment of this Rare Photosensitive Epilepsy

Epilepsy with eyelid myoclonia (EEM), formerly known as Jeavons syndrome, is a type of rare absence epilepsy characterized by a brief but intense and repeated jerking of the eyelids. Seizures can be triggered by bright and/or flickering lights and can be associated with abnormal EEG patterns.

EEM most often starts in children aged between 6 and 8 years and is more prevalent in girls than boys.

In this webinar, attendees learn how to recognize the clinical features of EEM, as well as how to differentiate it from other epilepsy syndromes.  The webinar also reviews the consensus first-line treatments for EEM.

About the Speaker:

Kelsey M. Smith, MD is an Assistant Professor of Neurology and epileptologist at Mayo Clinic in Rochester, MN. Her clinical and research interests include genetic generalized epilepsy syndromes including EEM, autoimmune-associated seizure disorders, and women with epilepsy. She is the first author of multiple publications that address the diagnosis and treatment of EEM.


Q&A with Dr. Kelsey M. Smith

We’ve talked about the difficulty of controlling seizures in this epilepsy syndrome. Since it is hard to treat, what level of control should be expected and how do we know when to consider a new or an additional treatment or medication?

I think that that’s a great question and it’s a question that I think should be very individualized and depends on the patient itself. So it depends on what a patient’s goals are. If the patient really wants to be driving, then we need to try to escalate therapy to the point where the patient isn’t losing awareness where that could be safe and also a risk-benefit ratio of trying a new anti-seizure medication. And so, I try and just have a discussion with my patient to see and for us to agree on that difficult question.

Does the VNS or DBS work for this syndrome?

So there’s limited data out there. In our series, we did have some patients who had VNS implanted from our 30 patients we published in 2018. I have personally seen some patients who’ve had some nice response to vagus nerve stimulation, but I would just say we don’t have enough knowledge. Deep brain stimulation as well, there’s even less knowledge on. There’s actually one case report of responsive neurostimulation to the thalamus, which is similar to deep brain stimulation. Deep brain stimulation is advancing in areas of generalized epilepsy, but there’s just not as much experience in generalized epilepsy. So that also includes epilepsy with eyelid myoclonia. It’s definitely an area of research and we should know more in the coming years.

It’s perplexing about lamotrigine. In your talk, you talk about lamotrigine works and can be prescribed, but sodium channels as a rule are not prescribed. So can you explain that dichotomy since?

I’ll try. And this is not just for epilepsy with eyelid myoclonia where there’s this dichotomy. So we know that lamotrigine works for some generalized epilepsy syndromes. We use it in multiple generalized epilepsy syndromes. It can make myoclonic seizures worse. There’s some good data for that. And there’s some debate about the eyelid myoclonia being just myoclonus of the eyes. But also, we know works usually well for the generalized tonic-clonic seizures and these generalized epilepsy syndromes. And that’s probably due to other properties than just the sodium channel blocking properties. And so, I think it’s a bit of a balance. If a patient has a lot of extremity myoclonus, that’s something to consider when starting the lamotrigine. But still typically, it’s one of our go-to medicines for generalized epilepsies despite its sodium channel, part of its action being at the sodium channel.

Have combinations of medications been trialed for effectiveness against DEM? This person has seen some better control during medication transitions when there may be multiple meds on board. Is there any evidence for that? ?

There’s no great evidence for that to, most of the studies looking at epilepsy with eyelid myoclonia are retrospective studies. And it can be hard when you look at some of that data for the confounding factors of multiple medications. It wouldn’t surprise me if there is sometimes a combination that works better balancing the eyelid myoclonia and things like that. But we just don’t have enough data to say, I would say. There’s a couple of retrospective series that puts some of the combinations together, but that data is limited and half interpreted.

So, there are some new medications available now. Is there any knowledge about how well Xcopri might work?

There was a series published actually out of Mayo by one of our fellows, Shruti Agashe, looking at Xcopri or cenobamate in generalized epilepsies. And I believe there was one patient with epilepsy with eyelid myoclonia in that. So obviously very limited data. There are studies that are hoping, my understanding is to study cenobamate or Xcopri in generalized epilepsies, and we don’t have the results from those in general. So I just don’t think we have enough knowledge at this time.

Webinar: Stem Cells & Epilepsy: A New Therapeutic Approach for Treating Drug-Resistant Epilepsy

Stem cells, the cells in the body that provide the blueprint for the creation of all other specialized cells (e.g., nerve, cardiac, blood cells, etc.), have generated significant interest in the research community over the past decade. Stem cells can help regenerate or repair tissues in individuals that have been affected by certain disorders and are being assessed for the ability to reduce seizures in people with epilepsy.

This webinar will discuss a pioneering neural cell therapy approach that could provide a novel treatment for drug-resistant focal epilepsy. Viewers will learn about the promising new data supporting this approach which will be presented by Dr. Robert Beach from the State University of New York (SUNY) Upstate Medical University.

About the Speaker:
Dr. Robert Beach, MD, PhD, is an Associate Professor of Neurology and Director of the Epilepsy Program at SUNY Upstate Medical University. His clinical interests include epilepsy, epilepsy surgery, anti-seizure therapies including medical, surgical, and experimental approaches, and differential diagnosis of seizures.

 


Q&A with Dr. Robert Beach, MD, PhD

Will this approach only be useful for epilepsy located in the temporal lobe or any drug-resistant epilepsy? Where do you see this going?

Well, if it is successful in this well-studied area of the brain, it will probably be useful in other focal epilepsies. As long as you can localize the seizures and target them with the cells, it has the potential to be beneficial. We’re starting with the best studied and most frequently treated surgically part of the brain as a starting point because it’s far and away the best understood and the most likely to provide us with realistic estimates as how it might work elsewhere.

 

Do you think it will eventually help people with Lennox-Gastaut syndrome or genetic disorders?Question?

Well, most genetic disorders are not focal. Some of them, like tuberous sclerosis for example, have multiple foci, and it might be useful in that sort of setting because it’s very hard to necessarily know which is the active focus. If you’re not damaging the area as you would with surgery or something, you may be able to treat more than one focus. But many of the genetic disorders are too diffuse and not well-localized enough to likely benefit from this kind of stem cell implant.

 

Can stem cell therapy be used in a patient who has a deep brain stimulator?

Well, not at this point, but it could be, theoretically. Deep brain stimulation is often used for less well-localized epilepsies, and some of those probably do not have a focal area that could be treated. Some of them have multiple focal areas of which you’ve … concurrently with the responsive neurostimulator or RNS, treat two of them, but not multiple ones. This could potentially have the ability to treat these area parts epilepsies where there are more than two foci or two focus that aren’t easily addressed by the RNS.

 

Are the cells manipulated in any way? Are they grown to increase their number
or cultured in any way? Selected in any specific ways?

Yes, all of the above. They are put into culture and they’re differentiated using a variety of growth factors and other things that influence distill differentiation. Then they’re tested to be these inhibitory GABAergic neurons, and then they’re expanded and tested for purity, and then they’re frozen in small amounts to be used in a particular implantation, and that you have multiple samples of the cells that can be used over a longer period of time with the frozen cells.

 

This isn’t actually coming from the person who’s having the surgery, but these are cells that were generated some time ago?

Yes. I don’t know exactly when they were generated, but they were generated from stem cells that have been obtained from, not from an embryo or not from a fetus, I should say. I don’t know exactly where they’re obtained from. Theoretically, you might be able to generate stem cells from the individual, which would have immense advantages in terms of not needing the immune suppression. That is one of the more complicated parts of this kind of approach, and I think that that’s potentially doable. It may be that cord stem cells may be more versatile and require less immune suppression. These are things that I don’t have a lot of information on, but are potential.

 

So, this person has a daughter with epilepsy, but an SCN1A mutation. They have stem cells saved from birth via the cord stem cell banking, and they’ve saved it from both of their children. Do you think this type of stem cell can come in handy for treating epilepsy?

That’s a very good question. I think there probably is a potential for those stem cells for this person, but I don’t think it’s going to be necessarily this kind of stem cells delivered focally, and it may not be primarily GABAergic neurons. It may be something that might introduce a different or correction of a different deficit that would be seen in SCN1A. But at this point, I really don’t know exactly how that would work.

 

How long does it take to see improvement, for example, a reduction in seizures after cell implantation?

Well, we don’t know. We were pretty surprised that this person did as well as he did in terms of seizures. So, the hypothesis that we are operating under is that the benefit of the cells would come mostly after they integrated with the other cells, and form new connections and new networks, which would take time. The plan was to assess this over a year, basically, be looking at six months, but expecting to find some realistic estimate over a year. This is, being the first patient, I think it’s premature to say that this is going to be a characteristic of everybody getting these cells, but it’s very encouraging.

 

If somebody has a VNS and can’t have an MRI, is it still possible to be assessed for this?

Well, a person with a VNS, as long as they don’t have it slipped way down below their chest or in the lower part of their chest, can have an MRI. There’s a, you require certain things in the MRI to be able to get, in the scanner, be able to get an MRI in somebody who has a VNS. There’s an absolute area of exclusion where if it exists, you can’t do it. But for the most part, they are coils that are used that go around the head and localize the flow of the changes of magnetic fields that keep it from interfering and keep it from damage the VNS. The VNS has to be turned off during the MRI. One obvious reason is if somebody has their magnet on and they go through the MRI, they’re going to be exposed to rapidly fluctuating magnetic fields, which will trigger it on and off multiple times, which would be intolerable very quickly. But most people with a VNS can get an MRI. If they have a focal abnormality that is likely to be the source of their seizures, or a couple maybe in the future, they may be candidates, but for now we’re looking at one focus.

 

So, back to the GABAergic interneurons, will they only work in the hippocampus or could they work in other areas?

Well, these are neurons that come from an area of the brain that spreads out throughout the cortex. The cells are formed in the median ganglia eminence, and then they migrate to various parts of the cortex. The reason it’s being tested in the hippocampus is because it’s a well-studied model, and we know that there’s GABAergic cell loss. They should potentially work in many other areas if there is a loss of GABAergic input and they can be replaced, which if there’s a loss of GABAergic cell loss, and it’s an area that can be, well almost in the area can be accessed using stereotactic implantation. So, probably, as long as there’s a focal area that can be identified as a seizure source, and there’s a good reason to think there’s GABAregic cell loss, it does have potential again, in the future.

 

How long do you think it will take to get a good readout from this clinical trial and know what the next steps will be? We’re getting a lot of questions about the future of this and where it could be used, but clearly, we’ve got to complete this trial first. Talk about this trial and how long it might go.

The way the trial’s set up now is the first two patients had to be separated by I think, three months. So, second patient was implanted about three months ago, who I don’t know much about their seizure effects or side effects. But I note, they’ve had no major side effects, and the cells were implanted a very similar way as to what I demonstrated with our patient in approximately on, well, actually as of now, there’s been several things that the Data Safety Monitoring Board has allowed us to do that’s going to facilitate getting patients in faster. One of them is to open it up for additional studies in this preliminary group of patients who are really getting a low dose, and there’ll be five people in that initial cohort that should probably be all implanted within the next six months, I would hope. Approximately a year after those five people go through, we should have some idea as to whether this effect on epilepsy is real, and whether there are side effects that we haven’t yet seen that are going to be an issue.

We also may have an idea, because they’ve opened it up now, so we can do non-dominant hemisphere patients, I’m sorry, dominant hemisphere patients as well as the non-dominant hemisphere patients. We may get an idea as to whether the most important benefit for this, it may be realized, and that is if you’re treating the dominant hemisphere temporal lobe epilepsy, in somebody who has relatively normal verbal memory and function, you’re going to get a decrement on surgery, because you’re going to be taking out areas important for that. But it is very possible, and it’s been shown with the less you take out, the more likely you are to have less effect on memory and language function. It’s very likely that with this kind of approach that you’ll have even less effect, or we hope that there’s even less effect on the language and verbal memory, and that we might have some information on that within the next year. I’m not really sure.

It might take longer than that, but it’s going to take larger numbers to really get a good sense for how likely various things are. I think we’re definitely seeing some very promising results, but it’s very early to know.

 

So, we’ve got a question about eligibility, and you’ve been talking about unilateral mesial temporal lobe epilepsy in the non-dominant side, and you just shared that there’s been a loosening of restrictions to also now allow the dominant side. It sounds like that might be because of the lack of concern around changes in some function.

Well, it’s because there doesn’t appear to be any major risk showing up from what we’ve done so far. It’s the dominant hemisphere of patients who this is most likely to be the most attractive approach for, because of that potential for sparing language function or even getting improvement potentially. So, as long as somebody has unilateral at this point, unilateral left or right mesial temporal sclerosis and seizures coming from that area, and no progressive degenerative diseases, and various other minor or unusual restriction criteria, they would be a candidate for this. But it’s basically, think of it as somebody who might be a candidate for epilepsy surgery on one temporal lobe, may be a candidate for this. There are some details beyond that, but that’s a good starting point.

 

Are there any discussions about trying this in children? I know that’s a difficult question, I’m sure.

Yeah. I think there will be plans to do that, because temporal lobe epilepsy is fairly common in children. But I think that there are some differences in, I would guess that’s going to take a while before we have a good handle on anything that’s going to actually try that. If it’s very successful, maybe a no-brainer to go forward with children, but it’s a little unclear at this point.

 

Do immunosuppressants have any effect on seizures themselves?

Not that I know of. I mean, they have side effects that can be somewhat systemic, but I’m not aware that any of them are actually anti-convulsant. Now, there are drugs that reduce proliferation that are in some ways related to the immune suppressants that can affect development of some of the epilepsies that require things like tuberous sclerosis, where you get growth of cell populations as tubers or as giant cell astrocytomas, where they suppress that. But that’s not truly an immune suppressant. I’d have to look to see what data there is. I’m not aware of any, but there might be some data on that.

 

Here’s somebody who is asking about autoimmune epilepsy and its impact on the hippocampus. The autoimmune epilepsy appears to have shrunk or changed their hippocampus. So, is somebody like this a candidate?

So, autoimmune epilepsy should first be treated to reduce the impact of the molecule causing the autoimmune response and the autoimmune response itself. If that is unsuccessful, and there’s residual long-term epilepsy, then they may be a candidate for this, but autoimmune epilepsy is usually a monophasic course where if you can remove the inciting antigen, which might be in some cases related to a tumor or an abnormal cell growth, or if you can suppress the response adequately, you can get control of those seizures in most people. And, if they are treated quickly enough and aggressively enough, they’re likely to get enough of a benefit. So, long-term epilepsy is not likely to occur, but for some people it does, and I think those people, if it’s in the hippocampus, would be candidates. I don’t think they’d be candidates for this study because that’s probably a restriction, but because autoimmune is not really a clearly defined stimulus that ends at a given time, but I think that they would be candidates for this kind of approach.

 

So why do the cells have to be injected into the brain? Why couldn’t they be injected into the bloodstream?

So, there are immune therapies to which are largely for blood cells where there can be replacement or treatment directly into the blood, and there may be epilepsies which are widespread and without a focus that might benefit from some blood cell treatments in the future. But for the effect of the GABAergic cells to be beneficial without causing widespread suppression of activity, you want to be able to put them where the abnormality is, where the hyperexcitability is, and that requires injecting them into the brain. There might be some genetic cases where that would be different, but not at this point.

 

Are there any outwardly visible components of implanting stem cells in long term?

Outwardly visible? Well, I guess if you palpated their skull, you might find a small little burr hole in the back where the burr hole is made. If the person is on long-term immunosuppressants, there might be some side effects that could last over a longer period of time, and of course, being on immunosuppressants does increase the risk for infections, but that’s not really a marker. That’s just a risk, I’d say.

 

You’ve talked about long-term immunosuppressants. It’s likely that people would have to be on immunosuppressants for their lifetime or do we know?

Probably on some level for lifetime. The aggressive approach initially is much more, all of, I think he was at one point on three strong immunosuppressants, and is now on a single low dose of Tacrolimus, which is one of the more common immunosuppress use for tissue transplants, which is probably not causing significant side effects at this point. Does have the increased risk of possible infection though.

 

Do you see this being used for any other kinds of neurological disorders?

Yes. I don’t think the, there’s probably ones where I think GABAergic cells may be beneficial, but I do think that stem cell of particular kinds will be useful in some other diseases, perhaps even in something like Parkinson’s disease where we now do stimulation, there might be potential to use certain kinds of cell implants to benefit there, but that’s something that I really don’t know for sure, and it’s in the future for sure.

 

So, you’ve talked about, you mentioned these people who are being enrolled are on a low dose. So, is the anticipated that the next steps in the clinical trial will try different levels of stem cell infusion or different numbers of stem cell infusions?

Yeah, the plan was to try a higher dose with the second cohort, which would be after these five people have gotten adequate results, which would be roughly a year from now or maybe slightly more. I’m not sure if the results are particularly impressive with the low dose. That may be modified.

 

Would be useful for generalized genetic epilepsies, and generalized epilepsies in general?

Well, I think most of the generalized epilepsies don’t have a focus where we could inject GABAergics neurons and expect to get a benefit. There may be particular subtypes of GABAergic cells that might be useful in some of the generalized epilepsies, but that’s very theoretical, because you’d have to be able to figure out which subtype and where to inject it. Theoretically, with some of the generalized epilepsies, it might be in the internuclear or reticule thalamic nuclei, which is part of the relay for some of the so-called spike-wave epilepsy, which are often called primary generalized. But I think that’s highly theoretical at this point.

Webinar: Mental Health & Childhood Epilepsy

Mental health and behavioral problems are just a few of the concerns that can affect children with epilepsy and these can vary greatly from one child to the next. While some people with epilepsy experience few if any mental health issues, others may suffer debilitating problems of inattention, anxiety, or mood disorders. It is important for parents and health care professionals alike to address these concerns early in their diagnosis as this can have a big impact on the quality of life for both the patient and their support system.

This webinar will cover:

  • Prevalence of mental health conditions in children and youth with epilepsy compared to the general population and peers with other chronic medical conditions
  • Risk factors associated with co-occurrence of epilepsy and mental health conditions
  • Importance and process of monitoring, evaluation, and management of mental health concurrently with epilepsy
  • Treatment approach using evidence-based mental health interventions

He is employed in the Epilepsy Center at Boston Children’s Hospital with clinical and academic efforts that focus on pediatric epilepsy syndromes, neurosurgical outcomes, and cross-cultural application of neuropsychological assessment. He is also an Instructor of Psychology in the Department of Psychiatry at the Harvard Medical School. Dr. Vega also practices as a consultant in criminal and civil forensic neuropsychology, public schools, and the Boston Red Sox.


Q&A with Dr. Clemente Vega

Can you briefly explain what ODD (oppositional defiant disorder) is?

It’s essentially the difficulty following rules, and just adhering to the structure in the environment. It’s essentially a child, or adolescent who does not have problems respecting authority, does not follow rules, breaks the rules on purpose, and presents with this type of behavior for at least six months, or more. And they seem to essentially also engage in other types of less socially appropriate behaviors like lying, or deceiving others, stealing, and so on.

The studies will show that it can range the prevalence [of ODD in children with epilepsy] is anywhere between five, and 20%. It often co-occurs with other inhibitory condition, other conditions that present with difficulties with inhibition like ADHD, and it can also be a transient side effect of medication. So, sometimes medications that cause aggression for example, or cause a lot of frustration, difficulties with frustration tolerance. The way that presents in the environment is a child who just doesn’t follow rules, breaks the rules, doesn’t want to do what they’re being told to do, whether it’s at home, or at school. So, generally, studies will be as high as 20%, some as low as 5%. I think most of the meta-analysis will put it on the lower end. It’s not as common as depression, anxiety, and ADHD.

It’s really important to talk about the side effects of medication with the physician, and as you mentioned, some have negative side effects, and some have more mood supporting side effects, right??

Yes, and it’s very important for me to mention that I’m not trying to talk about the medicines in a negative light. I think it’s important to keep in mind that the medicine’s goal is to try to control the seizures as best as possible, and having more seizures is going to have a worse long-term effect on mood, anxiety, ADHD, and academic performance if they’re experiencing some cognitive side effects related to the medicine. So, the side effects of the meds sometimes are present, but they are less to a degree compared to how those same symptoms may present when the seizures are happening more often. There is a tipping point where the severity of the side effects, and the benefits therapeutically of the medicine from a seizure control perspective may not make sense for that particular individual. So, trying other type of meds may be a better option.

This is often seen for example in a medicine like Keppra, which does great, in terms of controlling seizures in a ton of in to ton of patients that have both generalized, and focal seizures but can present with side effects of irritability, negative mood, and some aggressive behavior. So, maybe that is [inaudible 00:35:57] Some people only have that in the beginning, or the first few weeks of the medicine. Some people actually get… They don’t go away. So, that’s something I like to mention. I also think it’s important for all of us when we are starting medicine to get a general sense of behavioral presentation in the weeks, to a month leading up to the beginning of the med, and the first four to six weeks after starting the meds, and then the next couple of months after. Because it all kind of blends together the frequency, and severity of behavioral side effects of meds, or cognitive side effects of meds with the difficulties that were there before the med was introduced, because they’re just part of the epilepsy.

They’re having a lot of seizures, or the disruption in sleep, or some of the other changes that are associated with the medical condition that may be there with, or without that particular medicine. So, having a, I’m not necessarily promoting journaling on a daily basis, but maybe on a week to week sitting down, and trying to get a sense of the presence of some of these mental health symptoms such as anxiety, depression, irritability, difficulties with attention, and problems in school. So, we can track little bit before meds in the beginning of the meds, and after the person has reached the therapeutic level of the meds maybe four to six weeks afterwards.

Are there any genetic epilepsies more at risk for psychosis?

I’m not familiar with any particular genetic conditions increasing the risk for psychosis. I can say, generally speaking, in the psychology world, we understand that psychosis is found more in populations that have neurocognitive impairment for example, and also in populations that have a family history. So, perhaps not necessarily, maybe it’s there, and I’m just not familiar with it in terms of genetic conditions increasing the risk of psychosis. But we do know that genetic conditions also increase the risk of neurocognitive impairment compared to epilepsies that have a different type of etiology. And it may just be the multiple factors that are associated with the genetic epilepsies that increase the risk of psychosis if it’s something that the person asking the question has been finding, or is familiar with, or something that makes sense to them. But to date, I haven’t come across any literature that has presented that as a risk factor.

A viewer has heard that stimulants are not as effective with SCN 1A epilepsy. Would that be true? Do you know?

So, I don’t know about SCN1A, and stimulants specifically, but I do know that stimulants tend to be less well tolerated in some populations with epilepsy. SCN1A is a condition that usually comes with a lot of other situations. They tend to have a lot of medicine, because the seizures are hard to control, and in my experience a lot of my patients that have neurological conditions, whether it’s epilepsy, or something else, have a higher risk of having side effects of any medicine that they are taking. So, stimulants are known to have side effects, and the population may just be much more at risk of having side effects. The problem with stimulants sometimes it’s not that they don’t help the cognitive aspect of the person, it’s not that they’re not helping attention, it’s that we can’t reach the therapeutic dose without having significant side effects such as irritability, depression, and difficulty sleeping, and appetite.

I also have worked with folks that spend a lot of their research career with populations that have autism, which is known to occur more frequently in genetic epilepsies that have SCN1A mutations, and their practice tends to be used more non-stimulant medication before stimulant medications like Stratera for example, because it’s much better tolerated, and they can reach therapeutic levels compared to what type of efficacy they can have with the stimulant meds. But I haven’t come across specifically research with SCN1A, but it would make sense to me if somebody publishes that, why that would be a problem.

Are there ways for parents to screen for mental health, and needs in younger children like toddler, pre preschool-aged children?

That’s a challenge for an anybody, even parents that don’t have children with… Whose children do not have epilepsy. It’s most of the studies that look at general populations age when depression, and anxiety begins to actually present, when certain states have looked at this for example, and they estimate that anxiety, and depression really begin to emerge more between the ages of eight, and nine years old. So, ADHD presents more often between the ages of five, and six, but we hesitate to diagnose, or to talk about someone who’s presenting very sad as being depressed when they are young like a toddler, or even a preschool-aged kid, or kindergarten age kid. Similarly, we are very hesitant to start thinking about ADHD in a toddler, or someone who’s even three, or four years old, because in my experience most toddlers have a lot of difficulties paying attention, and they have a lot of hyperactivity.

So, it’s very challenging to differentiate what is a clinical mental health condition versus just kind of normal brain in that young age. That being said, I will always recommend the parents of any age, of kids with any age to just monitoring change in their behavior over a course of on a week to week basis. Any of our kids can be a little bit more irritable, a little bit more sad, or a little bit more anxious, or different in their behavior presentation from one day to another. Kids are very sensitive to changes in their schedule, in their sleep patterns, in their nutrition, and we may just be seeing a transient change in behavior as a result of some of these environmental variables. But if we start measuring on a week to week, a change that seems to be a little bit more there between one week, or another week, and really notice a change that we can compare to what was going on the month before, or the month before that, that’s how we can start really identifying the potential presence of anxiety, depression, or sadness in children that are younger like toddlers, and kindergarten.

The studies also say, also show us that anxiety, and depression may present very differently at that young age compared to how it presents in middle childhood, or even as we get into adolescents, and in adulthood, they tend to, for example, in anxiety tends to present more as mutism, or social isolation when they’re really young. If they’re in school, they stop playing, they stop talking, they stop interacting with others. Mood changes may present much more as irritability, and crying, but not necessarily verbalizing that they’re feeling a particular way. And also changes in their kind of basic physiological activity like changes in sleep patterns, changes in appetite. Those may also be more signs to be on the lookout for with younger kids that are three, four when we are trying to make sure that the anxiety, or mood are not being affected by whatever is happening, whether it’s a condition, or changes in their treatment.

For absence seizures, would mental health issues lessen if the child were to grow out of these types of seizures?

Unfortunately, the answer to that depends on that particular person. So, there is evidence that the curing the seizure, or outgrowing the syndrome does not always predict the resolution of a mental health condition. And they’ve done these kinds of studies in Canada where they look at folks that have these pediatric conditions, and trying to predict based on seizure control, or seizure severity whether the mental health condition will be benefited, or they outgrow it. And what they found is that there’s very little way, there’s no way to actually predict it. Some people get better, and some people don’t. And we are still trying to figure out what may be some variables that can differentiate that. Is it the family history, that maybe predisposes some folks to have depression, or ADHD regardless of the presence of absence epilepsy? Is it environmental factors, or something else?

So, I would say that there is a subset of children, and youth with epilepsy that experience these mental health conditions as a consequence of their epilepsy that the effects that it has on their academics, or their quality of life is impacting them to the extent that it is increasing their anxiety, and their feelings of sadness, and depression, and honestly as a human being that makes perfect sense to me. Oftentimes, I think my patients are so resilient, and so strong because they don’t present with the degree of anxiety, and depression, and other symptoms that I think would be a total normal response to having to deal with a medical condition like this.

And folks that are having this sort of direct response to the changes that they experience as a result of the condition, we would expect a lot of improvement as they outgrow the condition like absence epilepsy, and whatever contribution may be there with the meds to their mental health that won’t be there anymore if they’re [inaudible 00:47:32] not taking meds. But there might still be an underlying biological process that is really contributing to their mental health that will be present, whether the seizures are still there, or not as they transition into adolescents, and adulthood.

Are there any books that you would recommend for mental health, ADHD, epilepsy on how parents can do CBT (cognitive behavioral therapy)? What we know it’s that while this seems to be an available treatment for adults, in some areas it’s really hard to actually get access to a psychologist for children. So, are there programs that you would recommend, or books to support people in areas of our country where there don’t have easy access to specialists who know how to do CBT?

Yeah, so for ADHD first, there are a few books that were written for parents that I always find very helpful, and I recommend often. Maybe not for ADHD primarily, but for the symptoms of ADHD, which are frequently just executive dysfunction problems, just getting their task organized, planning, and problem solving. And there’s a book that is called Smart but Scattered, there’s version for younger children. There’s a version for adolescents, and there are a version for young adults. Again, the book is called Smart but Scattered, and it was written by neuropsychologists who do a lot of work in ADHD, and it’s essentially a parent guide. There are books on mindfulness, and on behavioral therapy that may also be available. There’s a lot of these, I don’t think I recommend one over the other. I would say a few things. Hopefully, now, as we are transitioning to more telemedicine availability, then people can have more access to mental health services compared to where we were before telemedicine became so normal.

So, that may increase access a bit. The other thing is that the providers who don’t specialize in kids may be okay under certain circumstances. It’s really hard to find someone who is a specialist in mental health that matches all of the needs of one particular patient that I work with who knows epilepsy well, and also knows anxiety, and also knows anxiety in this particular [inaudible 00:50:38] adolescent female that’s 15 as an example. So, I tend to create a bit of a decision trait, because of the treatment that I’m referring for is the mental health condition, an anxiety specialist with good training is able to translate their work into epilepsy if they don’t have a lot of work with children, and youth that have epilepsy, and may be able to adjust what they do. Someone with experience with adolescent may be able to work with a high functioning 10, or 11 year old, for example.

When it’s younger kids, CBT may not actually be as helpful. It may be more helpful to do parent type of therapy that may be more accessible in the community, or something that can be managed with a multidisciplinary team like the school, and counselors along with the parents, and some of the physician providers. I can probably go back into my library, and look for some of these CBT specific books that may be very helpful, and answer that question more specifically, but I can’t think of a specific book off the top of my mind for that one.

We’ve talked a little bit about Keppra, and its impact on mood. One question we have here is about phenobarbital. Do you know if it changes aggression, or mental health has an impact?

Well, I know that phenobarbital has cognitive effects, and it’s associated with slowing processing speed, difficulties concentrating, and can cause fatigue. These can certainly have an effect on mood. As I mentioned earlier, if we are fatigued at any point, or for any reason, we’re going to have more difficulty modulating our feelings, and our emotions, and maybe more anxious if we have cognitive effects, and have difficulty keeping up with what is expected of us on a regular basis, that’s going to make us more anxious, and it’s going to impact our mood as well. I’m not familiar with a lot of studies looking at higher rates of depression, or irritability in patients that are prescribed phenobarbital.

We tend to see more of a cognitive effective profile in that particular medication as opposed to more of a mood, or anxiety profile in that medication. But I think it’s important to always keep in mind that anybody can have any kind of side effects with these medicines, because our brains are so different that we know of some side effects that may present more often than not, but that doesn’t negate the potential of other side effects, or any side effects being there with any medication.

A question about cognitive behavioral therapy (CBT), and would it be recommended when adolescents also have cognitive regression?

So, I guess that may depend on the degree of regression, but if the question is related to an adolescent that may have some pretty significant cognitive difficulties, or maybe not to the degree of an intellectual disability, but certainly having a lot of difficulty keeping up with the expectation academically, or otherwise in their day-to-day. So, they’re certainly not functioning at the level of their age, and maybe a few years behind. CBT may be much more challenging, or ineffective in someone who they can’t process the information at a cognitive level, and it’s a lot more reflective, or maybe is more immature in their behavioral presentation. So, behavioral therapy that is less cognitive, but more based on reinforcements, rewards for behavior, and designing more of a behavioral treatment plan that is similar to what we would do for someone who’s younger, like a eight year old, nine year old, 10 year old, that may be much more effective for treatments compared to cognitive behavioral therapy.

If it’s an adolescent with cognitive aggression that is presenting with more of the anxiety depression, there are other treatment options that may be better, like DBT (dialectical behavioral therapy) has been shown to be effective in adolescents for treatment of depression, and anxiety, and it’s a lot more on the here, and now type of behavior management as opposed to changing our cognitive thinking, or our patterns of negative thinking over the course of six months. That may be very challenging. Someone to make the slow gains if they have cognitive progression, and they may just need more of a here, and now type of approach for management like DBT can present, or other forms of behavioral therapy.

“Treatment Talk” Treatment of Focal Epilepsy: Advancement Toward Medical Remission

This Treatment Talk, a social-media broadcast that will be released on CURE Epilepsy’s YouTube channel, will discuss focal epilepsy and the most recent treatments to help patients achieve medical remission. The talk features Dr. Michael Smith, Senior Attending Neurologist and Director of the Rush Epilepsy Center in Chicago, and Sarah Carlson, a patient of Dr. Smith’s who battled epilepsy and its corresponding stigma for many years before achieving seizure freedom. Viewers will learn about focal epilepsy, how a new treatment (cenobamate) can offer patients the hope of medical remission, and the benefits and risks identified in recent clinical trials of cenobamate.

This talk is supported by an independent educational grant from SK Life Science.

Webinar: The Role of Medicinal Cannabis and Cannabidiol in the Treatment of Epilepsy

Medicinal cannabis has been of interest to the epilepsy community with greater interest fueled in 2018 by the FDA approval of a cannabidiol (CBD) extract called Epidiolex®.  In fact, the marijuana or cannabis plant contains over 100 different substances, two of which specifically, CBD and tetrahydrocannabinol (THC), have been widely studied to understand their effects on the brain.

THC is the major chemical compound found in marijuana that creates a psychoactive effect when it binds to receptors in the brain. CBD binds to a different set of receptors and is not psychoactive. Epidiolex® is a purified, plant-based CBD extract used to treat seizures associated with rare genetic epilepsies. Because of its effectiveness, there is great interest in further understanding how CBD acts in the brain and also if other cannabinoids might be useful in the treatment of seizures.

In contrast, marijuana products sold in dispensaries and online are not approved or regulated by the FDA. They can vary significantly in quality, dosage, safety, and effectiveness. In some cases, commercial, nonprescription cannabis products are thought to increase seizures.

This webinar will review the basics of cannabis biology and the differences between cannabis strains. It will also explain the medical uses of medical marijuana and the recent approval of CBD to treat specific types of epilepsy.

Dr. Eric Marsh is an Associate Professor of Neurology at the University of Pennsylvania Perelman School of Medicine and the Children’s Hospital of Philadelphia (CHOP). He is the Clinical Director of the Penn Orphan Disease Center, and Director of the CHOP Rett and Related disorders clinic.

Dr. Marsh’s clinical interests include developmental and epileptic encephalopathies (DEE), neurodevelopmental disabilities, and cortical malformations. His research interests have focused on the role of intraneuronal development and altered excitability on epilepsy, analyzing intracranial EEG recordings to better localize the epileptic zone and network, and performing natural history and biomarker studies. In addition, he has studied the role of mutations in specific genes related to epilepsy such as ARX and CDKL5. Dr. Marsh has been involved in a number of clinical trials for children with the DEEs, including Dravet, Lennox Gastaut and Rett syndromes.

 


Q&A with Dr. Eric Marsh

Has CBD been found to affect the metabolism of benzos other than
Onfi?

So yes it does. Onfi is a unique benzodiazepine, in that its structure is different. So most benzodiazepines, the side chains off the benzo ring, which is why it’s called a benzodiazepine, are on the first and sixth carbon. Onfi, it’s the first and fifth carbon, so it’s a unique benzodiazepine. That’s the name Onfi, one five. It’s off of the first and fifth carbon, so it’s a unique benzodiazepine. But all benzodiazepine are affected, though Onfi more so than the rest.

Would CBD or Epidiolex be considered a treatment for epilepsy or autism in megalencephalic leukoencephalopathy (MLC)?

So there’s kind of two ways to answer that. So our expanded access program included a lot of different rare genetic disorders, and the effect was the same across the board. I think everyone now believes that Epidiolex, or purified CBD, is a good broad-spectrum anti-seizure medication, and that, for any different cause of epilepsy, it should potentially have some effect. As the data showed, it’s not a cure for most, it just reduces seizures. And you would expect the same for whether MLC is the cause of the person’s epilepsy or anything else.

The second way to answer is that too, for the FDA-approved Epidiolex, there are indications that are required, including Lennox-Gastaut syndrome, Dravet, and TSC. So for MLC, the question would be, does the child have the electrical clinical pattern consistent with LGS, in which case, they could have LGS due to their MLC, in which case they’d actually be allowed to be prescribed the FDA approved Epidiolex. If they don’t, then your doctor would have to prescribe it off label, and that’s a discussion to have with your doctor.

And then same thing with the behavior, as I said, there might be positive responses in behavior. I think you just have to be very critical if you try to treat an individual with this. If you don’t see anything, then like any drug, stop it. Don’t continue it just because you want it to work, but really be critical of whether you think it’s working or not

Can oils from dispensaries be tested, to understand what they correct amounts are from using a third-party tester?

Yeah, so absolutely. There are labs around the country that will test. I don’t know what the cost is, so I don’t know if it’s prohibitive to have something tested. Which also brings up the other issue with dispensaries, which I didn’t mention, because that study didn’t go over it, is batch to batch variability. So if you test it at one time, you might say, oh look, it actually is exactly what it says, but the next time they produce that batch, will they have the same accuracy of what they say is in the product is now in the product?

So you could get to a third party tester to test, but that will just give you reassurance for that batch of the product you have. For the next batch, you’d have to do it again. So I think, to some degree, when you go to a dispensary, you have to have a conversation with them, get as much reassurance from them that they’re doing it in a rigorous way, the way they grow, and the way they extract, and the way they produce. And then, just know that if you see a difference from time to time that it could happen. And if seizures are in good control, and seizures stop being under good control, it could be because the product has changed.

Is there a shelf life for these products in oil? How long can you keep them?

Yeah, so there is. Cannabinoids are actually light-sensitive compounds. So that’s why the bottle that it comes in, like Epidiolex comes in, is a brown bottle, in order to filter out light getting into it. And you should store any dispensary or FDA-approved cannabidiol in a cabinet out of the light, because light will make the product degrade rapidly. In the dark, in a cool environment, its shelf life is fairly stable. I don’t want to give you numbers, because I don’t actually, don’t quote me on a number, but it is fairly stable if it’s kept in the dark and cool. But I’m not going to give a number, because I don’t remember offhand what the stability is

What is the dosage of CBD in Epidiolex?

Epidiolex is 100 milligrams of CBD per ml. And the FDA recommended starting dose is five milligrams per kilogram per day, divided in two doses. And there actually is no max dose. So it’s based by weight. There’s no max dose in reality. The FDA label might have one, so I don’t remember if the FDA label has a max dose of like 1000 milligrams a day. Most of my patients are little kids, so we don’t get to that, they’re all small, so that’s not an issue. It’s all weight-based dose for me.

So is cannabidiol only used as a treatment for tonic, clonic, and atonic seizures? Are there other seizure types that might be, it might be useful for?

So for the studies, motor seizures, whether tonic, clonic, or atonic, were the primary endpoint, and that’s where we saw the greatest effect. In my own personal practice, I’ve had families who have LGS with multiple different seizure types, see response to a variety of the different seizure types, including myoclonic seizures, absence seizures, and focal seizures. Though it seems to be greatest for the kind of generalized tonic, clinic, bigger seizures.

Would using THC recreationally affect the effectiveness of clobazam or lamotrigine in generalized epilepsy?

So yeah, THC also alters the metabolism of some of the CYP enzymes, and I don’t remember the direction to which it does, but it does. So medical marijuana, taking a whole product recreationally, is going to potentially alter the metabolism of some of your medications, particularly in that case, clobazam. Less so lamotrigine, but I’d have to look up what the metabolism of lamotrigine is, to say for sure.

Have the individual terpenes been studied for their potential therapeutic effects on epilepsy?

Not that I’m aware of. So I know that GW/Jazz is really interested in exploring other aspects of the cannabinoids and terpenes for their role. But I’m not aware of any information that they’ve published to this end. And there are mouse basic science studies looking at some terpenes and other cannabinoids, but nothing human that I’m aware of.

Are there substantial side effects, such as liver or kidney damage, with use of CBD?

So far, the answer is no. That it is, in all the studies, there was no effect on kidney function. The liver questions a good question. So what was found in the studies, was that there was a increase in liver enzymes in a group of the patients. None of the patients got to the point where there was any issue of liver damage, but there was suggestion that the liver was being irritated. Because an elevation of the ALT and AST, the enzymes we used to measure kind of liver function, and they all went back to normal when you stopped the cannabidiol. So we don’t think there’s any long-term effect, but again, the medication’s only been approved now for six, seven years. So I think, long-term we’ll learn more about that, as people follow patients who are on cannabidiol for longer and longer periods of time.

This person says that their son is on Epidiolex, and it causes high anxiety. Is there anything else that might explain this, or might not cause the high anxiety? Is there anything that could be done?

Yeah. That’s a good question, and I would need a lot more information to really answer that question. As the Epidiolex could be interacting with other drugs, it’s possible by the alteration of the metabolism of another drug is bringing out his anxiety. So it could be related, but indirectly related. And in my experience, I’ve had families report that when they started Epidiolex, that it improved anxiety. But I also have some families who’ve reported that they think their kid’s more anxious, or their behavior has gotten worse on Epidiolex. So I think there’s a lot of variability there.

And one of the things I didn’t mention is that, these cannabinoids are actually, they don’t get absorbed very well via the gut, and so, they’re the metabolism and the individual’s ability to absorb and process these are going to be very variable. So some of the differences we might be seeing in this might be due not to how the drug works in their brain, but also, how the drug even gets into the body. So differences you see, something like that, could potentially be what we call pharmacokinetic, or pharmacodynamic properties, and not actual brainderived properties. But that said, we do, there’s a lot more we need to learn about these things

In the graph that you showed, there where a majority of people showed a reduction in seizure activity, but some actually saw an increase in seizure activity. I’m wondering if you can comment on that, and the variability there?

Yeah. So there’s two aspects of that. So one is that, we know that individuals who have epilepsy, and particularly epilepsy that has not responded to many medications, their seizures often fluctuate, and that they go up and down. And there’s some really nice data from people who’ve had RNSs implanted in them, where they’ve been able to follow count, people’s seizure counts for months on end, that we see these oscillations in people’s seizures. So one possibility for that increase, is that they started the trial at the low point, and they, as the trial went on, they just were in their normal up oscillation, and the medication had no effect, neither good nor bad, but it just looks like it went up, because they happened to be on an up oscillation.

The other potential possibility is that, yeah, for whether it’s a metabolism issue or a brain issue, that it actually altered the brain dynamics in such a way that it made someone’s seizures worse. So again, there’s still a lot we need to learn about that group who did really well. Who are they? Why are they? And can we figure those people out? So we know, hey, you’re their best people to put on Epidiolex. That would be something that would be great to be able to do. And unfortunately, we don’t have that type of data.

Can you take Epidiolex at the same time as Depakote or other seizure drugs, or should you be separating them in time?

Yeah. So you can take them at the same time. What’s important for Epidiolex is, because of the absorption issues that I just mentioned, is that you try to do it always at the same time, or approximately the same time, particularly around meals. So you don’t want to give it one time with food, and the next time without it, because it’s going to be absorbed differently. So always give it with food, or always give it without food, so that you’re just consistent. So that’s the best advice for when you give it, is trying to give it as consistently as possible, so that you know its effect, and that you’re not getting variable amounts based upon how it’s being absorbed.
