Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The overall goals are to determine whether patients with epilepsy who have the highest risk of SUDEP have an underlying genetic cardiovascular disorder. The investigators are seeking patients with epilepsy who have a high risk of SUDEP identified by using a risk scoring tool called SUDEP-7 and/or have blood-relatives with a history of epilepsy, seizure, cardiac arrest, sudden death, drowning/near-drowning, syncope or heart rhythm disorder. The investigators may also include blood-relatives of patients with epilepsy and invite them to participate by providing a blood sample and/or buccal cells (from a swab or saliva) for genetic testing.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

High SUDEP risk cohort

Patients with epilepsy who have a high SUDEP-7 risk score and/or a blood-relative with epilepsy, seizure, cardiac arrest, sudden death, drowning/near-drowning, syncope or arrhythmia.

No interventions assigned to this group

Low SUDEP risk cohort

Patients with epilepsy and a low SUDEP-7 score.

No interventions assigned to this group
