I have been diagnosed with cerebellar ataxia and still in the progress of finding out what is causing it. had all kinds of bloods taken and mri tests. In between I've had thyroid checked and all comes back ok and no antibodies. However I've started to itch from head to toe. Also eyebrows are missing at the end and I've read thyroid antibodies can attack the cerebellum but I've had the tests and all ok with thyroid. I do have thyroid cysts/nodules. Does anyone else have this problem.
