About this study

Epilepsy is a common condition which affects over 3 million people in the US. Patients with uncontrolled epilepsy have a lifetime risk of sudden unexpected death (SUDEP) of 35%, which is greatest in those under 40 years of age. The exact mechanisms and causes are not understood but can be due to underlying conditions which affect the heart and brain, which may lead to dangerous heart rhythms and death. Some of these conditions which affect heart and brain have an identifiable genetic cause. This study aims to identify known genetic causes of heart rhythm and sudden death related disorders in patients with epilepsy.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
