Migraines are neurovascular headaches. “Neuro” stands for the nerve component and “vascular” for blood vessels. Another primary issue that directly causes migraines is disruption in cerebrospinal fluid, which is crucial for proper brain function. Migraines are intense throbbing headaches that last for hours at a time occurring as frequently as several times per day or as infrequently as a few times per year. These are different from common tension headaches.
