This morning I sat down in front of my computer to post a question on the list...I got my messages first...and there was the question I was going to ask...driving and PWP. My sister and I drive to Parkinson's Support meetings together. A few months ago I noticed that she was driving with her left hand on the wheel and laying her right arm in her lap. When I asked her about that, she said her right shoulder hurt and her affected hand was weak, so she doesn't raise it to hold the steering wheel with both hands. I urged her to get both hands up on the wheel for safety and not to coddle that hand just because it wasn't as strong as it used to be. Two months ago while driving to the meeting, I noticed she was driving the car towards the right and onto the white line on the passenger side of the road and nearly side swiped a parked car on two ocassions. When I pointed that out, I again urged her to put her weak arm up and hand on the steering wheel because I felt that her stronger left side was over compensating and steering the car to the right. I urged her to focus on staying in the center of the lane and be aware of the car drifting to the right. She said she did not notice that she was doing that. Last month while driving to the meeting she told me that yesterday she had had a flat tire...the right front passenger tire had gone flat from damage to the sidewall where the tireman said she probably hit a curb. It was then that she realized she had a previous flat six weeks ago and it was the right front tire again, also with damage to the sidewall and months ago a hub cap was missing off her right front tire. She brought the three right front tire incidents together and realized that my obervations were accurate and that I wasn't a "back seat driver" but I was someone who had brought her attention to a problem that she wasn't aware she was having. She asked me if I thought the problem was caused by PD and if I thought she was safe to drive. I told her that physically her eyes were healthy, she did not have damage to her brain, her right side was weaker but that if she accepted the fact that she tends to drift to the right but keeps both hands on the wheel and focuses consciously to stay in the center of the lane for a period of time...then she may be able to compensate and develop a new awareness of where the car is while driving. She's been driving since 15y.o. and never had an accident. Now her daughters tell me that when the light turns green after a stop, she sits there and gets honked at and that when she does accelerate, she drives too slow...I noticed this too but I figured I was just being a "back seat driver"...now I don't know. She is 49yr old, diagnosed 6 months ago, symptomatic 2 yrs, only on Eldepryl 5mg bid, and symptoms are very mild. Has anyone else had similar experiences? Is this a common problem for PWP? How could her problem be explained? Gail Vass, cg for sister...email address [log in to unmask]
