Dutch researchers followed up on a group of men and women nine years after they had an initial brain MRI.
They found women with migraines had more deep white matter brain lesions than women without migraines.
However, lesions did not progress faster in women with more frequent or severe migraines.
While an increase of lesions was not associated with cognitive decline, there could be a higher risk for stroke among these women.
There was no such link in men with migraines.
