When one has a stroke, that’s a huge insult to the brain. When the brain is insulted, it gets crabby and you’ll experience brain fog. For the first few months after my stroke, I didn’t fully understand what the hell was going on. My brain was damaged and not working properly. I still have brain damage but the effects of it are much different now that it’s a chronic condition as opposed to acute. I still don’t talk and walk as well as I’d like but there are absolutely no cognitive issues. I can think very clearly, and I think I’m still quite smart. :). It just doesn’t seem like it to people that don’t know me well. Oh well, I’m way over being embarrassed by this.
