Migraines Don’t Raise Dementia Risks

Tuesday, 14 August 2012 02:59 PM

Migraine headaches can be debilitating for those they afflict, but new research shows they do not increase sufferers’ risks of developing dementia or having significant cognitive declines later in life.
Researchers with Brigham and Women's Hospital researchers noted past studies have linked migraines to a higher risk of stroke and structural brain lesions, but the new study found they don’t increase the odds of mental-health declines.
The study, published online in the British Medical Journal, was based on an analysis of health records of more than 6,300 women enrolled in the long-running Women's Health Study, tracking the health of nearly 40,000 women who are 45 years and older.
"Our study was large enough to draw the conclusion that migraines, while painful, are not strongly linked to cognitive decline," said lead researcher Pamela Rist, with the Division of Preventive Medicine at BWH.
"Compared with women with no history of migraine, those who experienced migraine with or without aura did not have significantly different rates of cognitive decline. This is an important finding for both physicians and patients. Patients with migraine and their treating doctors should be reassured that migraine may not have long term consequences on cognitive function."
Migraines affect about 20 percent of American women. BWH researchers said more study is needed to determine the consequences of migraine on the brain and improve treatment strategies.
The study was funded, in part, by the National Heart, Lung, and Blood Institute.
