I returned to England at the end of 2014 to see a NHS Neurologist, he was unable to find the DAT scan. I also consulted a German Neurologist in 2010 who 'questioned' the scan results. I the past 2 years I have been examined by 4 Neurologists and had 3 different opinions regarding my condition.
To answer your question; the Neurologist in Singapore said that I did not have Parkinson's however, he did not offer an a solution to my condition.
My DAT scan was performed at The RVI in Newcastle, my results were interpreted by Professor David Bates (retired) who said "machines make mistakes too".
Thanks for your response,
