Anything mental or physical taking over 15-20 minutes and I am done in - totally exhausted. Until my stroke I had no idea what total exhaustion was. After a rest I am back to "normal".
My short-term memory is also poorer. It is now over 3.5 years since my cerebellum brain bleed, but I think there has been little improvement over the last year or so. Walking on pavements with traffic is very hard.
