Hi again Deb,
How are you doing?

There is straightforward info on this first site I think.
Second link is from same place but has downloadable Fact Sheets.

Ataxia causes
Ataxia resources and FAQs
From the National Ataxia Foundation.

http://www.ninds.nih.gov/disorders/ataxia/ataxia.htm
NINDS Ataxias and Cerebellar or Spinocerebellar Degeneration Information Page

Hard to find ones that are less "medical", Deb but there are some older posts here in the forums from people who have been diagnosed with spinocerebellar ataxia. If you use the search feature that I post below you can type in keywords and it will bring up those threads and posts.

NeuroTalk Forum Search Feature

You could start a new thread in either
Movement Disorders Forum
or in
General Health Conditions and Rare Disorders Forum

I would make the title "Spinocerebellar Ataxia" and that way if people are searching for this particular condition the thread will come up in the search more easily.

Edited to ask: Do you by chance have celiac disease?
Any family history of ataxia or have you had any genetic testing to determine a particular "Type" of spinocerebellar ataxia that you could have (as some are hereditary).

take care there and sorry to be so long-winded.
Lara
