The incidence of migraine headaches rose dramatically during the 1980s, particularly in women, according to a new study by researchers at the Mayo Clinic.
The study, which was published October 22 in Neurology, compared first-time migraine diagnoses documented in patient medical records from 1979 to 1981 with those from 1989 to 1990. Records from 1342 patients were included in the study. Overall, the incidence of migraine increased by 56% in women and 34% in men. The most striking rate of increase was in women aged 20 to 29—from 600 to 1000 new cases per 100,000 women per year. In men the same age, the rate increased from 200 to 250 per 100,000 men per year.
