i have these spells were my vision and brain goes wacky. i can't even call my best friends names. i have trouble reading words. it goes away after an hour or two and then i get a head ache that lasts for a day or two . i usually have 2 or 3 of these spells and then periods of time without them. they come out of nowhere. some have called it optical migraine but with the mental disfunction i don't know . please help with any advice. i live alone and am very frightened. thanks redtex.
