I do not recall whether it was his left hand or his right hand. He was interviewed by Dr. Sanjay Gupka on the CNN Larry King show. I did not watch this show, but I read several articles about when I did a google search to try and find ANY information about BHO suspected of having Parkinson’s Disease. There was nothing about BHO, but there was scads about Bill Clinton, because so very many people have noticed that he has was is the typrical presenting symptom of early Parkinson’s Disease — a parkinsonian tremor in his finger(s.) IF it is PD, soon he will have a hand tremor.
About watching Clinton for Parkinson’s... (my husband has it)
True, the finger tremor is an early symptom, but not all go on to develop Michael Fox type jerking movements. Some just become stiff, rigid, and develop a “Tim Conway” walk.
The inability of the brain to maintain smooth muscular coordination can vary in Parkinson’s. One thing that might be easier to spot would be the muscles around his eyes. If he develops a “staring” expression, that would be another clue.
