Brenda, You did not say what sort of stress you are scheduled for, but chemically induced sounds like it could be PERSANTINE. I had this test a couple of years back and had one of the worst "offs" I have ever had. I could not move either arm -much less hands or fingers- and my chest muscles almost stopped working which made breathing most difficult. Make sure you have competent medical personnel in attendance [in same room - preferably in a hospital setting ] with a ready supply of oxygen and the stimulant or whatever [apomorphine?] to reverse the effects of PERSANTINE. My reaction may not be the same as that of most other people with PD. There was no residual effect, and my scan looked pretty good considering that I had a jim-dandy heart attack in 1977 with damage.
