From what I can tell it mostly involves the brainstem which does all the basics of keeping you alive and the cerebellum which is balance and coordination and not any of the parts of the brain that are associated with hallucinations etc. However I did see one case report that suggested that in one patient it was associated with psychosis however it is in a foreign journal and I only have the title to go on. So basically there is nothing suggesting the two are linked.

Did you get to see pictures of your brain?
