Evaluating cognitive impairment in patients with focal cryptogenic epilepsy

Cognitive Impairment in Drug-resistant and Drug-responsive Focal Cryptogenic Epilepsy: a Longitudinal Observational Study

Observational IRCCS San Raffaele · NCT06210022

This study is testing how epilepsy affects thinking skills in people with different types of epilepsy to see if brain activity patterns can help understand their cognitive challenges better.

What this trial studies

This observational study aims to assess cognitive impairment in patients with drug-resistant epilepsy (DRE), drug-sensitive epilepsy (DSE), and newly diagnosed epilepsy (NDE) through clinical evaluations, neuropsychological assessments, and high-density EEG recordings. Participants will undergo evaluations at baseline and follow-up periods of 6 and 12 months for DRE and NDE patients, while DSE patients will only be assessed at baseline. The study will investigate the relationship between cognitive function and EEG patterns to understand the prognostic value of these assessments in epilepsy management.

Who should consider this trial

Good fit: Ideal candidates include Italian-speaking adults aged 18-60 with focal cryptogenic epilepsy, either drug-resistant, drug-sensitive, or newly diagnosed.

Not a fit: Patients with epilepsy types other than focal cryptogenic epilepsy or those outside the specified age range may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of cognitive impairment in epilepsy, leading to improved patient management and treatment strategies.

How similar studies have performed: While there have been studies on cognitive impairment in epilepsy, this specific approach focusing on DRE, DSE, and NDE with high-density EEG is relatively novel.
