Hello and welcome to the NeuroTalk Support Groups.
I'm sorry to read about your diagnosis. I can only suggest posting on the
Movement Disorders Forum
or
General Health & Rare Disorders Forum
You could also try using specific keywords in the forum search feature.
e.g. Ataxia or cerebellar ataxia
I just tried quickly using ARSACS and Charlevoix-Saguenay but I didn't find anything.
Forum Search Feature
If you have Neuropathy as part of the symptoms, you could also check on the 2 forums I've posted below as you may find some tips to deal with your symptoms on a daily basis.
Peripheral Neuropathy Forum
It also has a subform for
PN Tips, Resources, Supplements & Other Treatments
All the best to you.
