According to my wife, I was surprised to hear that I have had 3 or 4 episodes of rather violent shaking of my entire body as I sleep. The vigorous vibrations do not wake me up but they wake my wife. I am 70 years old and in the early stages of PWP, diagnosed about 2 years ago. I believe that the shakes are related to PD but I have not heard nor read anything about them. Does anyone have information about night shakes? I would appreciate hearing about them. RV Fisher ................................................................. Richard V.
