Memory Declines Less in People with Migraine
Effect observed in individuals with aura and those over 50 years old
MONDAY, April 23 (HealthDay News) -- Memory in individuals diagnosed with migraines is initially worse but declines less with time than individuals without migraine, with the effect specific to individuals with aura and those over 50 years old, according to a report in the April 24 issue of Neurology.
Amanda Kalaydjian, Ph.D., and colleagues from Johns Hopkins University in Baltimore, compared cognitive function in 204 individuals diagnosed with migraine headaches and 1,244 individuals without migraine at baseline and 12 years later.
The researchers found that although immediate and delayed memory scores were lower at baseline in individuals with migraine, these scores declined less over time than in individuals without migraine. The effect was limited to individuals with aura and those over 50 years old.
"Migraineurs, specifically those with aura, exhibited less decline on cognitive tests over time versus non-migraineurs," Kalaydjian and colleagues conclude.
