Migraine and dementia may not be connected. According to an analysis of data from 6,349 participants of the Women's Health Study, women who experience migraine—with or without aura—do not have more cognitive decline in later years than women with no history of migraine. Five tests were used to judge cognitive status, including immediate- and delayed-recall and memory tests administered in telephone interviews. Thirteen percent of participants reported migraine; among those, 23% had experienced aura and 29% had no history of aura. Overall cognitive performance was similar or even slightly better in the migraine group than among those with no migraine history. “Based on these results, patients with migraine and their treating doctors should be reassured that migraine may not have long-term consequences on cognitive function,” write the authors in the British Medical Journal, published online August 8.
