It,s not a definite but a possibility because i am not responding to drug treatment and the progression is relatively quick. Other indicators are speech, breathing, posture.

I haven't been responding either to the medication. I started out low dose a year ago and now on 50/200 extended release 6x daily. Not as much as some but I think it is a lot.

From what I was told, OH(orthostatic hypotension) is the hallmark sign of MSA. That then is divided into two groups. A test called the tilt table test is done to check for dysautonomia.

I regret to say that I have been told that I do have MSA, but my doctor said that he is reluctant to give me an official confirmation saying it because of lack of test. So we both said that Parkinson's disease would have to do.
