Migraine
A migraine is a common type of headache that may occur with symptoms such as nausea, vomiting, or sensitivity to light. In many people, a throbbing pain is felt only on one side of the head.
Some people who get migraines have warning symptoms, called an aura, before the actual headache begins. An aura is a group of symptoms, including vision disturbances, that are a warning sign that a bad headache is coming. See also: Cluster headache, Tension headache
Causes
- Migraines occur more often in women than men
- Migraines may run in families
- Some women, but not all, may have fewer migraines when they are pregnant
A migraine is caused by abnormal brain activity, which can be triggered by a number of factors. However, the exact chain of events remains unclear. Today, most medical experts believe the attack begins in the brain, and involves nerve pathways and chemicals. The changes affect blood flow in the brain and surrounding tissues.
- Caffeine withdrawal
- Changes in hormone levels during a woman’s menstrual cycle or with the use of birth control pills
- Changes in sleep patterns
- Exercise or other physical stress
- Missed meals
- Smoking or exposure to smoke
- Any processed, fermented, pickled, or marinated foods, as well as foods that contain monosodium glutamate (MSG)
- Baked goods, chocolate, nuts, peanut butter, and dairy products
- Foods containing tyramine, which includes red wine, aged cheese, smoked fish, chicken livers, figs, and certain beans
- Fruits (avocado, banana, citrus fruit)
- Meats containing nitrates (bacon, hot dogs, salami, cured meats)
- Onions
* This list may not include all triggers.
True migraine headaches are not a result of a brain tumor or other serious medical problem. However, only an experienced health care provider can determine whether your symptoms are due to a migraine or another condition.
Symptoms
- A temporary blind spot
- Blurred vision
- Eye pain
- Seeing stars or zigzag lines
- Tunnel vision
Not every person with migraines has an aura. Those who do usually develop one about 10 – 15 minutes before the headache. However, an aura may occur just a few minutes to 24 hours beforehand. A headache may not always follow an aura.
Symptoms may linger even after the migraine has gone away. Patients with migraine sometimes call this a migraine “hangover.” Symptoms can include:- Feeling mentally dull, like your thinking is not clear or sharp
- Increased need for sleep
- Neck pain
- Feel throbbing, pounding, or pulsating
- Are worse on one side of the head
- Start as a dull ache and get worse within minutes to hours
- Last 6 to 48 hours
Other symptoms that may occur with the headache include:
- Chills
- Increased urination
- Fatigue
- Loss of appetite
- Nausea and vomiting
- Numbness, tingling, or weakness
- Problems concentrating, trouble finding words
- Sensitivity to light or sound
- Sweating
