I too have wondered if there was any relationship between stress and the incudence of PD onset. In my case, I was the father of five and aat forty I had gone to seminary. After four years of seminary in Tennessee I found myself deeply in debt with no job prospects. My wife had just lost her job. There was a chance that I would find a job in Oregon. So, we moved to Oregon.. Shortly after moving to Oregon I began having symptoms like my hand writing getting difficult, my gait becoming uneven and my right arm not naturally swinging when I walked. I have wondered if there was some relationship to the onset of PD and the period of high stress that I had just gone through. David L. Moreland
