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. Migraine headaches, also known as migraines, are a type of headache that can cause debilitating pain Learn more about the types, causes, symptoms, diagnosis, & treatment of migraines. Here’s what you need to know about migraine headaches, including types, symptoms, triggers, treatments, and how they’re different from regular headaches.
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. 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 factors that will, in turn, minimize the impact on migraine. In most people, a throbbing pain is felt only on one side of the head
This activity can be triggered by many things But the exact chain of events remains unclear Most medical experts believe the attack begins in the brain and involves nerve pathways and chemicals. 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. Migraines can be triggered by certain activities, foods, smells, or emotions
Some people are more likely to experience migraines when they are under stress, while others develop migraines when stress is relieved (for example, the day after exams or an important meeting).
