Evaluating memory and forgetting in epilepsy patients

Evaluation of Episodic Memory and Accelerated Long-term Forgetting in Patients with Drug-resistant Focal Epilepsy

Not applicable Interventional Hospices Civils de Lyon · NCT04924933

This study is testing how epilepsy affects memory in people with drug-resistant focal epilepsy to see if it changes how they remember experiences and their context.

What this trial studies

This study focuses on patients with drug-resistant focal epilepsy and aims to assess their episodic memory through a computerized associative memory task. It investigates how epilepsy affects the brain's ability to link experiences with their context, which is crucial for memory formation. Participants will undergo a comprehensive neuropsychological assessment to evaluate their memory capabilities and subjective complaints. The study seeks to better understand the cognitive disturbances associated with epilepsy and their impact on quality of life.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with drug-resistant focal epilepsy and subjective memory complaints.

Not a fit: Patients with major depressive syndrome or those who have undergone epilepsy surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of memory impairments in epilepsy patients.

How similar studies have performed: While there is ongoing research into cognitive disturbances in epilepsy, this specific approach using computerized tasks for memory evaluation is relatively novel.
