Very interesting and well done website developed by a gentleman who has ataxia. He has written several disclaimers. He is not a doctor or any other medical professional, but he certainly has put together a lot of information.
May be some of you have seen this before, but because the author admits that it is difficult to find this site, I thought I would post it.
