You may know already, but if not ...
If you have to go to hospital and have an operation, try to avoid having a general anaesthetic. Unfortunately, my Dad had a fairly routine operation, but died from complications due to aspirating in the recovery room.This was because his throat muscles weren't very strong and the doctors had not realised that people with ataxia have this problem. They told us that if other members of the family with ataxia, had to have an operation, be certain that the anaesthetist is very aware of the weakness and does not remove tubes too early.
Sorry to be so depressing, but I think it important that you are aware of the potential danger and can point it out.
