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
MIGRAINE
CAUSES
Migraine headaches tend to first appear between the ages of 10 and 45. Sometimes they may begin later in life.
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.
Migraines occur more often in women than men, they may run in the family and some women, but not all, may have fewer migraines when they are pregnant.
TRIGGERS FOR MIGRAINES:
Alcohol
Certain odors or perfumes
Loud noises or bright lights
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
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
Vision disturbances, or aura, are considered a “warning sign” that a migraine is coming. The aura occurs in both eyes and may involve any or all of the following:
A temporary blind spot
Blurred vision
Eye pain
Seeing stars or zigzag lines
Tunnel vision
Other warning signs include yawning, difficulty concentrating, nausea, and trouble finding the right words.
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
FOODS THAT MAY TRIGGER MIGRAINES:
Any processed, fermented, pickled, or marinated foods, as well as foods that contain monosodium glutamate (MSG)

Meats containing nitrates (bacon, hot dogs, salami, cured meats)
