Migraine-sparked vision loss may increase stroke risk in women; Migraine

Researchers found that women who experience vision loss during a migraine are 70% more likely to have a stroke. Migraines without visual symptoms do not significantly increase stroke risk. The study's findings suggest that women with migraines and aura should address other stroke risk factors, such as smoking.
