Migraine

Migraine is a recurrent disabling headache, throbbing in nature, often associated with nausea and vomiting. It may affect just one side of the head, though the side may vary in different attacks. Some sufferers experience a warning sign - an 'aura' - that an attack may be on its way. This may involve changes in vision (flashing lights, temporary blindness) or numbness or tingling in one part of the body. Sometimes attacks may be triggered by particular foods, overwork or periods of stress. It is thought to be due to the action of a particular chemical - serotonin - on blood vessels in the brain. Besides avoidance of trigger factors, which may reduce their frequency, attacks may be stopped by agents such as sumatriptan, or prevented by using prophylactic agents taken every day.
