Thanks Radgirl. Someone was kind enough to move this to the medical forum.
Yes, I have seen a neurologist, had lots of tests - including a brain MRI - and been given a definitive diagnosis. I have been referred to CAA guidance entitled, "Certification after Cerebrovascular Events Stroke & Transient Ischaemic Attack" but having sought definitions of these on the web it seems to me that I have suffered none of them.
I was just wondering whether other people who'd experienced TGA had been ushered down the same track and how that worked out.
