I have been monitoring this list for a couple of months now. I am interested because my mother told me two years ago that a doctor had told my father he had a mild case of PD. But the doctor felt there was no need for medication because there were only mild symptoms and the drugs have many side effects. My parents live in a rural community with three new and inexperienced doctors. The original doctor has since retired. In a telephone conversation with my parents and also after visiting with my parents at Christmas I am wondering if the time has come for my father to consider medication. It seems as though his temor is becoming very troublesome when he is stressed. After a recent week in which he attended four funerals in three days, he had what my mother call an "attack of nerves". It appears as though his whole body was convulsing with the shaking. This I had never observed before. I believe my father is reluctant to admit it could be PD. But does anyone know if it is possible to take medication only when having difficulties. I suspect my father would be willing to consider that possibility more readily than admitting that he needed regular medication. I have been following the messages with interest and I always felt like an intruder but I can assure all of you that I do have a personal reason for needing to be aware of the developments of PD.
