I don't know if anyone has posted this but I was reading my new IFS magazine and came across an article of Lee Ann Miller who just recently suffered two strokes. She had a neck injury which resulted in a blood clot that traveled to her brain. It goes on the say that she couldn't remember when she had injured her neck. She is continuing physical herapy, but I know once you have a stroke that it is hard to come back 100% if you can at all.
I had a close friend who at 42 suffered a stroke and even though he was young and made great physical improvements he never regained complete physical movement. Unfortunately he decided that if he couldn't be 100% he didn't want to live anymore. He commented suicide about 2 years ago.
