Migraine headaches are severe, recurrent headaches generally accompanied by other symptoms like visual disturbances or nausea. They tend to begin on one side of your head, although the pain may spread to both sides. You may have an “aura” (warning symptoms that start before your headache) and feel throbbing, pounding, or pulsating pain. A migraine is caused by abnormal brain activity, which is triggered by stress, food, or something else. The exact chain of events is not known. However, it seems to involve various nerve pathways and chemicals in the brain. The changes affect blood flow in the brain and surrounding membranes. Migraines occur in women more than men, most often between the ages of 10 and 46 years. In some cases, they appear to run in families. Migraine attacks may be triggered by: allergic reactions, bright lights, loud noises, physical or mental stress, changes in sleep patterns, smoking or exposure to tobacco smoke, missed meals, alcohol, hormonal fluctuations (related to menstrual cycles or use of birth control pills). True migraine headaches are not a result of underlying brain tumors or other serious medical problems. However, only an experienced health care provider can determine whether headache symptoms represent migraine or some underlying medical condition that requires further tests. This assessment can only be made after a review of a patient’s history and a complete neurological exam.
