Severe headaches of any kind can be debilitating. Symptoms of severe headache include intense pain, usually on both sides of the head. Migraine, in addition to severe pain on only one side of the head, may be accompanied by neurological symptoms such as distorted vision, nausea, vomiting, and sensitivity to light or sound. In 2007, 12.3 percent of adults reported experiencing a severe headache or migraine in the past 3 months (data not shown). Severe headaches and migraines are more than twice as common among women as men (16.8 versus 7.4 percent, respectively). For both sexes, the rate of severe headaches and migraines is highest among those aged 25–44 years and decreases with age. Among women aged 65 years and older, only 5.9 percent reported severe headaches or migraines in the past 3 months, compared to 22.4 percent of women aged 25–44 years.
