A migraine is a neurological condition resulting in recurrent attacks that are headache-like in nature, but are longer in duration and more severe than a typical headache.
Migraines may be linked to the flow of blood to the brain. Constriction in certain blood vessels causes a corresponding dilation in other blood vessels, which results in inflammation. At the onset of a migraine, the blood vessels in your head first shrink, then swell, causing pain. Migraine pain tends to be localized to one side of the head, although it can spread to the other side. The length and frequency of migraine attacks varies. Migraines can last minutes, hours, or even days. Some people have them weekly, while others have less than one per year. Migraines usually begin sometime between the teen years and the age of 40, and can be classified as either Classic or Common. Classic migraines are often preceded by visual disturbances, including flashing light, and odd physical sensations that can include tingling and numbness, and nausea and vomiting. Other symptoms that signal the onset of a Classic migraine headache include sensitivity to noise, light, or smells; tunnel vision; and a prickly, hot, or weak feeling on one side of the body. These symptoms are known collectively as an aura. However, most migraines do not involve an aura. Common migraines are more often preceded by feelings of depression or restlessness, or by periods of talkativeness, 2 to 3 days before the headache starts. A wide variety of stimuli have been reported to trigger the onset of a migraine headache, including tension, bright lights, loud noises, strong smells, weather changes, fatigue, missed meals, and emotional upset. A migraine may also be brought on by many common foods and beverages, including lunchmeat, hot dogs, alcohol, beans, coffee or tea, cheese, chocolate, nuts, pickles, raisins, canned soup, and artificial sweeteners. In addition, many women suffer migraines before or during their monthly period, although both the occurrence and severity of migraines in women seem to decrease with age.
