Can an MRI or CAT SCAN pick up the fact that one has Parkinson's Disease or is the diagnose made entirely on the basis of symptoms? A friend's mother has started to exhibit jerky movements and is getting confused. She has had an MRI and CAT SCAN and nothing has been concluded. Could she have Parkinson's Disease? I think they have taken her to a neurologist but Parkinson's was not mentioned. ******************** Gail M.
