The risk of stroke was significantly increased after age 65 years (hazard ratio, 6.0 [95% CI, 1.4\u201326.3]). Dementia, mild cognitive impairment, migraine with aura and depression were equally prevalent in cases and controls. Twenty-nine cases (25%) and 45 controls (24%) had an available brain magnetic resonance imaging. After age 65 years, cases had a higher white matter lesion burden and more lacunes.
