I've read that migraine is an increased risk factor for stroke, but I've read articles that state both that it's migraine and migraine with aura. I'm wondering if it's only with aura or both? I've had migraine without aura for about 10 years, which turned from episodic to chronic in 2010. I recently had a mild stroke which left my left side weak and with some cognitive impairment. I'm a 57 year-old woman with no known risk factors for stroke. The doctors can't explain why it happened, but I am thankful that it wasn't worse.
