The University of Texas Medical Branch, Galveston
Summary
This study is testing a new approach to help people with migraine headaches. Researchers want to find out if using electrical stimulation to affect blood flow in the external carotid artery is safe and practical for helping control headaches. The goal of the study is to determine whether this approach could improve headache symptoms and overall outcomes for people with migraines.
