well ,I was diagnosed with possible Parkinsons about 4 months ago , then sent for a DATscan , which confirmed it ... but when i saw the neuro's notes on the computer screen he had written to my dr that he thought it was 'psychogenic' .....? do I take it to mean thats 'all in my head' or can you have that WITH a positive DATscan ... I was under the presumption that psychogenic meant sorta psychosomatic ?? i.e no loss of dopamine ?
