Fair question and to be honest I'm not entirely sure. All I know is that I've had tremors since maybe 10 or so years old, went to a pediatric (I believe) neurologist during high school (over 10 years ago) and they diagnosed it as that. My grandfather has had tremors most of his life but no PD. We always attributed it to PTSD from the Holocaust and then fighting in WWII (came with the Americans to Omaha Beach on D-Day and nearly drowned, later was captured, etc.) but the fact that I clearly never experienced those things must possibly mean it's genetic. Though nobody else in my immediate family has it.
