This may have been asked before, but I feel I need to get my heard around this one. Dopamine levels - Before any symptoms show themselves, about 40 - 60 percent of them have already gone. Also doing exercise does not create them, it just releases them and enables your brain to take advantage of them, it also enables your brain to become more productive with what you have left.
The reason for this is I have to have a DaTSCAN and I’m concerned that the exercise levels which I currently do may upset the scan if your body naturally produces it from exercise, which if my understanding is not correct, this is not the case! If that was the case, everyone who had PD would be exercising themselves to the limits of there own physical body.
So, another question is will exercise upset the readings of the DaTSCAN reading
Also a DaTSCAN is not to accurate with early diagnosis?
Snippit from Appraised by Kevin Galbraith, January 2016 " The single study evaluating DaTSCAN in early PD v normal yielded what was reported in the metaanalysis as a low Sn of 38%.(5) " and " which has itself been found to be incorrect in 6% to 25% of cases. " It’s also down to what the Doctor perceives too!
Is this correct, or does this mean something else?
I’m trying to get my head round some of the bits. Over a month ago, one doctor (I can see recommendation for him online and was recommended by another movement specialist) who said he was about 95% certain I had PD and to keep up the exercise as it was certainly helping (Which I know it to be as I was much worse beforehand) the second was not as convinced even though he said there are some tell tail signs, is questioning it.
Although I do not want to have Parkinson’s, I have been on a long journey with another Neurologist who was a complete waist of time and it now seems everyone who I speak with also says the same within the medical profession which I find quite scary. But ultimately, I do not want to be left high and dry either if the readings come back normal as the second Doctor has indicated.
I’m feeling extremely deflated at the moment since seeing the second doctor and since I have reduced my exercise levels because I do wish to upset the DaTSCAN results, I’m also experiencing a lot of my older symptoms which I found with exercise had massively reduced.
Any thoughts would be helpful
