Could a Heart Defect be the Cause of Migraines? - A Potential Breakthrough in Treatment

The video discusses how migraines may be linked to heart defects, specifically a small hole in the heart that allows blood low in oxygen to bypass the lungs and reach the brain. This defect is more common in migraine sufferers and may lead to increased serotonin levels, which can trigger migraines. If studies confirm that repairing the heart defect alleviates migraines, it could change migraine treatment approaches.
