Low-Intensity Focused Ultrasound Targeting the Dorsolateral Prefrontal Cortex for Preventive Treatment of Chronic Migraine

28 września 2026 zaktualizowane przez: Zhao Dong, MD, Chinese PLA General Hospital

Efficacy and Safety of Low-Intensity Focused Ultrasound Targeting the Dorsolateral Prefrontal Cortex for Preventive Treatment of Chronic Migraine in Adults: A Randomized, Single-Blind, Sham-Controlled Trial

Chronic migraine is a disabling neurological disorder characterized by frequent headache attacks and significant impairment of quality of life. Low-intensity focused ultrasound (LIFUS) is a non-invasive neuromodulation technique that can precisely target deep brain regions. This study aims to evaluate the efficacy, safety, and tolerability of LIFUS targeting the left dorsolateral prefrontal cortex (DLPFC) for preventive treatment of chronic migraine in adults.

This is a randomized, single-blind, sham-controlled clinical trial. Eligible participants with chronic migraine will be randomly assigned to receive either active LIFUS stimulation targeting the left DLPFC or sham stimulation. Participants will receive 10 stimulation sessions over 2 weeks and will be followed for 3 months after intervention.

The primary outcome is the change in monthly migraine days from baseline to 1 month after intervention. Secondary and exploratory outcomes include headache-related disability, quality of life, psychological assessments, electrophysiological measurements, neuroimaging changes, and safety outcomes.
