The vision consequences are scary. While I was in hospital a man was admitted, maybe early 60's, looked fit and clean cut, but it blinded him without warning, and no other effects. Perhaps it will resolve but the whole thing is a lottery. There is a tenuous link with migraine with aura, which I started getting in my 60s. Not often, maybe twice a year, but I had one the night before the stroke, and as usual there was no pain, but the visual disturbance was darker than the usual Scintillating Scotoma, which is what I get.
It could maybe be migraine doing yours Bob. The Consultant told me that migraines can present similar to strokes, separated after the MRI scan.
