Diagnosed with ataxia; wondering how can i find other people who have it and how it affects them?

This might depend: How to find a support group for a diagnosis of ataxia might require knowing why you have it. There are genetic reasons for ataxia and support groups for those diagnoses (like spinocerebellar disease). A place to start is www.Ataxia.Org as they will have options. If a different reason, ask your diagnosing doctor for assistance.
