Clots in veins may be more common with migraines.
THE QUESTION Should people who get migraine headaches be on the alert for clogged veins or arteries?
THIS STUDY involved 574 people, age 55 and older; 111 of them had experienced migraines. Based on medical records and ultrasound scans of arteries in the neck and thighs of all participants, there was little or no difference in the presence, severity or progression of atherosclerosis (narrowing of arteries from plaque buildup) among those who did and did not have migraine diagnoses. However, 19 percent of people with migraines had experienced venous thrombosis (blood clots in a vein), compared with 8 percent of those who had no history of migraines.
WHO MAY BE AFFECTED? People who experience migraines, which occur up to three times more often among women than men.
CAVEATS Data on migraines were based in part on participants' recall, as well as on neurological exams.
FIND THIS STUDY Sept. 16 issue of Neurology.

The research described in Quick Study comes from credible, peer-reviewed journals. Nonetheless, conclusive evidence about a treatment's effectiveness is rarely found in a single study. Anyone considering changing or beginning treatment of any kind should consult with a physician.
