Not sports related, but I had some similar situations related to the stroke zI had 4 years ago. About a year before it I got the aura like a migraine but without the headache several time. Being a stubborn Pollack, I ignored it. About two weeks before the stroke I had to drive 90 miles back home from a job and had a hell of a time concentrating on my driving. The week before the stroke, I got lost driving to a place i had been at least a dozen times before. Took me about 10 minutes to get my way there. Later that day I was going to a fast food place and using my phone for navigation. Couldn't find the place and kept blaming the phone. After driving for about 20 minutes, I passed a McD's and ate there. At least the 30 miles home was on the interstate.
