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.
Here’s what you need to know about migraine headaches, including types, symptoms, triggers, treatments, and how they’re different from regular headaches.
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.
But migraine is much more than just a headache. Learn more about the common causes, triggers, and risk factors of migraines.
Migraines are likely caused by a nerve that inflames the dura, spreading pain and changing local blood flow. There may also be genetic causes of migraine. There are multiple triggers that may lead to a migraine attack.
Key lifestyle factors that can impact migraine are sleep routines, exercise, diet, hydration, stress management and avoiding individual migraine triggers. From there, it’s easier to develop a plan to manage relevant f...
What is a migraine headache? The headache of migraine is usually throbbing and one sided, though it can affect both sides. It is often associated with nausea, vomiting, and light and sound sensitivity.
Migraine may occur due to a combination of genetic factors and environmental triggers. It may also involve changes in the brain, such as blood vessel swelling. Risk factors for chronic migraine...
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 ...
Symptoms other than pain can occur with a migraine headache. Nausea and vomiting, lightheadedness, sensitivity to light (photophobia), and other visual changes are common. A migraine headache may last from 4 to 72 hou...
