Is this trial a fit for you?

Likely a good fit

Adults over 18 with drug-resistant epilepsy, followed at Amiens Picardie University Hospital, and with recent video-EEG and MRI-compatible status.

Probably not a fit

Individuals without detectable hypothalamic structural differences or with non-contributory cardiac autonomic findings may not benefit directly.

What this trial studies

This Interventional study uses high-field 7 Tesla MRI to examine hypothalamic nuclei and related networks, alongside electrocardiography, to explore links between brain structure and heart autonomic function in people with drug-resistant epilepsy. Participants are adults with epilepsy managed at Amiens Picardie University Hospital who have recent EEG data and consent. The goal is to see if differences in hypothalamic anatomy correlate with measures of heart rate variability and sympathetic activity, which may relate to SUDEP risk. The study does not specify a therapeutic intervention beyond imaging and ECG monitoring. Safety relies on standard MRI screening and clinical oversight at a single center.

Why it matters

Potential benefit: Findings could improve understanding of SUDEP risk and inform future approaches to monitoring or preventing cardiac dysfunction in epilepsy.

How similar studies have gone: Previous research has linked brain structures with autonomic function in epilepsy, but this study uses ultra-high-field MRI and is relatively novel in this specific hypothesis.
