Multiple System Atrophy?

I was wondering if anybody knew anything about MSA. I recently found out that my father’s neurologist has changed my father’s diagnosis from Parkinson’s to MSA, so I’m particularly interesting in similarities/differences between the two. I’ve done some googling, but I figured someone on here might have first hand knowledge.

This may be more of an IMHO question, but I though I’d start by asking for facts.

Interested, not interesting. I noticed that just after the editing time ran out.
