Investigating brain activity patterns in movement disorders

Oscillatory Activity in Basal Ganglia Circuits During Normal and Pathological Movement

Not applicable Interventional University Hospital, Bordeaux · NCT06241924

This study is testing how brain activity changes during movement in people with Parkinson's disease and epilepsy to see if it helps us understand their conditions better.

What this trial studies

This research aims to explore the oscillatory activity in the cortico-subcortical network during normal and pathological movements in patients with Parkinson's disease and drug-resistant epilepsy. By utilizing high-resolution electroencephalogram (EEG) and stereo-electro-encephalography (SEEG), the study will collect local field potentials while participants perform a simple motor task. The goal is to understand the relationship between the characteristics of these oscillations and movement patterns, which could provide insights into the underlying mechanisms of these disorders.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 75 with Parkinson's disease who have undergone electrode implantation or individuals with drug-resistant epilepsy undergoing pre-surgical assessment.

Not a fit: Patients who are unable to provide informed consent or have serious psychiatric or somatic illnesses may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of movement disorders and lead to improved treatment strategies for patients with Parkinson's disease and epilepsy.

How similar studies have performed: Other studies have shown promise in understanding brain oscillations in movement disorders, but this specific approach using high-resolution techniques is relatively novel.
