Migraines are common and typically almost always develop before the age of 30. They can occur every few days to once every several months. Most migraine sufferers are female, and there’s a strong family history of migraine headaches. Migraines can be caused by changes in sleep pattern or by diet. Foods that contain tyramine, monosodium glutamate, nitrates, chocolate or citrus fruits can trigger migraine headaches. Hormonal changes, even birth control pills can also trigger onset of migraine headaches. Auras are a neurologic event that approximately 20 percent of migraine patients exhibit.
They precede the onset of the headache and may include visual disturbances, changes in smell, and hearing. Typically migraine headaches are limited to one side of the head, or unilateral. The pain is typically around the eye or behind the eye. It can be from mild to severe and pounding. Menstruation can be a common trigger of migraine headaches. Neurologic dysfunction can accompany migraine headaches rarely. No specific tests exist for diagnosis of migraine headaches. MRIs are helpful to rule out other causes of headache. Laboratory tests including CBC, erythrocyte sedimentation rate may be performed.
