Having migraines raises the risk of dementia, study finds

As if migraines didn't already cause enough suffering, a new study has found that people who experience the debilitating headaches are at much higher risk for Alzheimer's disease.

The study from two Canadian universities - the Universities of Waterloo and Manitoba - found that migraine sufferers were three times more likely to have a general dementia diagnosis and four times more likely to have Alzheimer's disease than peers without migraines. The headaches, however, were not associated with vascular dementia, a type of dementia caused by damaged blood vessels in the brain. Dementia is an umbrella term that includes both Alzheimer's and vascular dementia as well as less common types of cognitive decline.
