Parkinson’s Disease Treatment Parkinson's disease is a progressive disorder of the nervous system that generally affects movement. It is a long-term degenerative disorder of the central nervous system. The patient feels the most prominent effects on the motor system. The symptoms of the disease develop gradually starting with minor signs like a barely noticeable trembling of one of the hands. With time, other symptoms like shaking, rigidity, slowness of movement and difficulty of walking start registering their presence. Thinking and other behavioural problems may also follow. As the disease progresses towards its advanced stages, dementia becomes common. Get an effective treatment for Parkinson's Disease at PAL Physiotherapy from best physiotherapist.
