Novel Helmet Design in Patients with Seizures Clinical Trial

Brief Summary: This is a two-part study that aims to determine the reliability and safety of the use of the Hövding inflatable helmet in seizures, as evidenced by the deployment of the helmet during seizures, and qualitative patient reporting.

Detailed Description: Part 1: 4 healthy volunteers will fall from a standing position onto a padded surface to evaluate for consistent helmet deployment from a standing position. Part 2: up to 40 patients with drug resistant epilepsy who do not use existing head-protective devices will be enrolled and assigned to “helmet” or “no helmet” groups. Patients will be assigned to wear the helmet until deployment during a seizure, up to 6 months. Subjects will complete questionnaires about their seizures including any injuries sustained, post concussive symptom questionnaire, and the circumstances of inflation. Patients will return to site after helmet deployment. We will compare circumstances, injuries, and post concussive scales in seizures where the helmet deploys to seizures, if present where the helmet did not deploy.
