Hi Reverett 123
I am a volunteer in a longitudinal study of the progress of PD in Oxford, UK and one of the tests was standing on one leg - timed. Another simple one which is used for Alzheimers as well was drawing a clock and the hand at I think "ten to eleven" - not quite sure. To my horror I marked the hands in wrong position and although I realised the error immediately I could not for the life of me stop being distracted by what I had done in order to correct the position of the hands and had to resort to starting from scratch drawing the clock again and then I was fine. At this point I began to have doubts as to the wisdom of volunteering
