I have had Parkinsons Disease for about 11 years. I have severe tremors in arms, legs, and mouth. I have had a few falls. Also i have dementia and have trouble finding my car sometime,Yesterday while leaving a movie theater I got into my car and healty wife was driving, She got a go to hell look by a fellow in a wheel chair and then he shook his head in disgust.Things are not always what they seem to be and maybe the guy in wheel chair felft that parking should only by used by those in wheel chairs? I have been asked by one health care profession if I should even by driving becasue of my tremors? What is everbodies opinion on this issue? Somethings are not clearly seen and may need to be defended?
