Novel Helmet Design in Patients With Seizures

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 20 patients with drug resistant epilepsy who do not use existing head-protective devices will be enrolled and assigned to first enter "helmet" or "no helmet" groups. When assigned to the "helmet" group, patients will wear the helmet until deployment during a seizure or up to 3 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. While assigned to the "no helmet" group, patients will complete the same questionnaires, except those relating to helmet inflation. We will compare circumstances, injuries, and post concussive scales in seizures resulting in falls occurring while the helmet was worn versus seizures resulting in falls occurring while the helmet was not being worn.
