What this trial studies

This observational study aims to assess changes in functional brain connectivity in patients with chronic or episodic migraines who are undergoing treatment with monoclonal antibodies targeting the CGRP pathway. Using high-density electroencephalography (EEG), the study will analyze brain activity and connectivity patterns to better understand the effects of these treatments on migraine patients. The research will focus on evaluating brain oscillations across different frequency bands to identify potential markers for therapeutic interventions. The findings could contribute to a more precise approach to migraine management.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with episodic or chronic migraines who are indicated for treatment with monoclonal antibodies or BoNT-A.

Not a fit: Patients with a history of epilepsy, psychiatric illnesses, or other significant neurological conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of migraine treatment effects and lead to more personalized therapeutic strategies.

How similar studies have performed: Previous studies have shown promising results in assessing brain connectivity in migraine patients, but this specific approach using high-density EEG with anti-CGRP mAbs is relatively novel.
