Jack Tibbs, You will want to see a good Neuro for special testing before you become overly concerned about having Multiple System Atrophy, otherwise known as Shy-Drager Syndrome, something you don't want to worry about unnecessarily. It is quite rare, and while it does have some symptoms in common with Parkinson's, the treatments can be different. The disorder is characterized by postural hypotension (an excessive drop in blood pressure which causes dizziness or momentary blackouts upon standing or sitting up). Has that been happening to you ? Tests can include: Plasma norepinephrine levels, urinalysis for norepinephrine breakdown products (urine catecholamines), EMG and EEG. For more information, Search the Web using Excite and the search phrase Shy+Drager, or go to http://miso.wwa.com/~claudec/shydrager/ and look around there for information and links. It's very important to get a second opinion based on thorough testing, then you can seek the best available treatments for a know condition. Best Wishes, John
