Understanding the role of the anterior cingulate cortex in refractory epilepsy

Localization of the Reward Positivity to ACC

Not applicable Interventional University Hospital, Ghent · NCT04684797

This study is testing how the anterior cingulate cortex works in people with hard-to-treat epilepsy by having them do a virtual maze task before their surgery.

What this trial studies

This interventional clinical trial aims to investigate the function of the anterior cingulate cortex (ACC) in patients with refractory epilepsy. Participants will undergo a virtual T-maze task to assess ACC activity during a pre-surgical work-up involving invasive video-EEG monitoring. The study will include two experimental sessions, with the first occurring after informed consent and prior to hospitalization. The findings may provide insights into the ACC's role in task selection and motivation based on reward prediction signals.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 years or older with refractory epilepsy who are scheduled for invasive video-EEG monitoring.

Not a fit: Patients with severe cognitive or psychiatric disorders, or those with active substance abuse issues, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of ACC function, potentially leading to improved treatment strategies for refractory epilepsy and related neurological disorders.

How similar studies have performed: While the specific approach of this study is novel, previous research has explored the ACC's role in various neurological conditions, indicating potential for meaningful insights.
