Digital Conversations about Suicide among Teenagers and Adults with Epilepsy: A Big-Data, Machine Learning Analysis

Abstract, published in Epilepsia

Objective: Digital media conversations can provide important insight into the concerns and struggles of people with epilepsy (PWE) outside of formal clinical settings and help generate useful information for treatment planning. This study aimed to explore the big data from open-source digital conversations among PWE with regards to suicidality, specifically comparing teenagers and adults, using machine learning technology.

Methods: Advanced machine-learning empowered methodology was used to mine and structure open-source digital conversations of self-identifying teenagers and adults who endorsed suffering from epilepsy and engaged in conversation about suicide. The search was limited to 12 months and included only conversations originating from US internet addresses.

Results: A total of 222,000 unique conversations about epilepsy, including 9,000 (4%) related to suicide, were posted during the study period. The suicide-related conversations were posted by 7.8% of teenagers and 3.2% of adults in the study. Several critical differences were noted between teenagers and adults. A higher percentage of teenagers are; fearful of “the unknown” due to seizures (63% vs 12% adults), concerned about social consequences of seizures (30% vs 21%), and seek emotional support (29% vs 19%). In contrast, a significantly higher percentage of adults show a defeatist (“given up”) attitude compared to teenagers (42% vs 4%). There were important differences in the author’s determined sentiments behind the conversations among teenagers and adults.

Significance: In this first of its kind, big-data analysis of nearly a quarter-million digital conversations about epilepsy using machine learning, this research team found that teenagers engage in an online conversation about suicide more often than adults. There are some key differences in the attitudes and concerns, which may have implications for the treatment of younger patients with epilepsy.
