my yoga teacher asked me why I was going to have te DaT Scan for atypical Parkinson's as the neurologist has already ruled out any drugs which I might take, so there is really nothing they can do if the result is positive. I would have to go to the hospital the week before the test to get 2 doses of iodine which I would have to take before the test, to protect my thyroid from the injection of radioactive tracer which I would have 4 or 5 hours before the scan. the whole thing has made me so anxious, and I am scared of the fact that I must stay away from children or pregnant women for 48 hours after the test because I will be radioactive. I am also terrified about the results. so would it be better to refuse this test and not to know, or will that also stop my TMS Progress, (anxiety has certainly stopped it at the moment) I could use some advice, because I have arranged to have ths test on 20th March, and need to tell the hospital asap if I have changed my mind. I suppose I feel that I SHOULD rule out anything structural. Any advice would be very welcome!
