| Causes |
| | Migraine headaches affect about 6 out of 100 people. They are a common type of chronic headache. They most commonly occur in women and usually begin between the ages of 10 and 46. In some cases, they appear to run in families. Migraine is the cause of 20 per cent of all headaches. This type of headache occurs when blood vessels of the head and neck constrict, resulting in a decrease in blood flow to the vessels. Migraine is usually experienced as a throbbing pain on one side of the head with an associated feeling of sickness and sensitivity to light and sound. Migraines are known to affect more women than men and are often chronic. Below are some of the factors that have been identified as being associated with migraines: family history of migraine. prolonged muscle tension and stress. alcohol use. smoking or exposure to tobacco smoke. lack of sleep. for women, menstrual periods and the use of oral contraceptives. certain foods such as chocolate, nuts and fermented or pickled condiments, as well as foods containing the amino acid tyramine (aged cheese, red wine, smoked fish) and foods containing preservatives and artificial sweeteners.
