What this trial studies

This observational study aims to investigate how attentional control is affected following a focal seizure in patients with epilepsy. The researchers will conduct a prospective longitudinal assessment of brain activity and cognitive performance during the peri-ictal period using high-resolution EEG and event-related potentials. By focusing on patients undergoing pre-surgery work-up for focal epilepsy, the study seeks to understand the disorganization of neural networks involved in attentional control post-seizure.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 80 with focal epilepsy who are undergoing pre-surgery work-up.

Not a fit: Patients who are pregnant, unable to provide consent, or have recurrent seizures that prevent proper monitoring may not benefit from this study.

Why it matters

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

How similar studies have performed: While there have been studies on brain activity during seizures, this specific focus on attentional control post-seizure is novel and has not been extensively tested.
