Though migraine causes aren't fully understood, genetics and environmental factors appear to play a role. Changes in the brainstem and its interactions with the trigeminal nerve, a major pain pathway, might be involved.
Researchers aren’t sure of the exact cause of migraines, but studies show genetics play a role. When you have a headache, specific nerves in your blood vessels send pain signals to your brain.
Current research shows that this head pain happens when there is abnormal activity among nerve signals, chemical signals, and blood vessels in the brain. Some people have migraine attacks at predictable times—such as before their period (menstrual cycle) or on weekends following a stressful week.
Here’s what you need to know about migraine headaches, including types, symptoms, triggers, treatments, and how they’re different from regular headaches.
But migraine is much more than just a headache. Learn more about the common causes, triggers, and risk factors of migraines.

Migraines begin in the brainstem and involve abnormal interactions between nerves and blood vessels. The trigeminal nerve—a major pain pathway in the face and head—becomes activated, releasing inflammatory substances that irritate blood vessels and amplify pain signals.
While they are considered primary headaches, meaning they have no known underlying cause, migraines are associated with an increased risk of stroke, brain scarring as seen on MRI scans, a heart defect called a patent foramen ovale (PFO) and other medical conditions.
True migraine headaches are not a result of a brain tumor or other serious medical problem. Only your health care provider can determine if your symptoms are due to a migraine disorder or other condition.
Migraine is a neurological disorder that predisposes people to migraine attacks. As noted above, the cause is genetic, and these genetic changes result in changes in brain chemistry that lead to the migraine tendency.
