Population Study Supports Migraine-Dementia Link

The analysis included 18,135 people registered with migraine before age 59 and 1.38 million without migraine, while the matched study population was 62,578. A diagnosis of dementia or use of dementia drugs after 60 years was the main finding, while socioeconomic factors, psychiatric comorbidities, and other headache diagnoses were covariates. The average age at diagnosis was 49 years and about 70 percent of the migraine population were female, with a 50 percent higher dementia rate in individuals who had any migraine diagnosis. A 20 percent dementia rate was observed in individuals who had migraine without aura, but assessment of this population found that its dementia rate was twice that of people with no migraine. "The dementia rate was higher if individuals had more frequent hospital contacts with migraine," said the University of Copenhagen's Sabrina Islamoska. She added that the research highlights "the value of investigating the effect of migraine medications in dementia risk to assess the impact of mild to moderate migraines."
