Parkinson’s disease is a degenerative disorder of the motor system in the central nervous system. It is caused due to the death of the dopamine generating cells of the mid brain. Parkinson’s disease is considered a synucleiopathy due to an abnormal accumulation of alpha-syncline protein in the brain in the form of Lewy bodies, as opposed to other diseases such as Alzheimer's disease where the brain accumulates tau protein in the form of neurofibrillary tangles.
Symptoms Symptoms of Parkinson's disease differ from person to person. Parkinson’s disease affects the nerve cells in the brain that produce dopamine. Parkinson’s disease symptoms include muscle rigidity, tremors, and changes in speech and gait. After diagnosis, treatments can help relieve symptoms, but there is no cure.
The crude point prevalence rate (October 20, 1991) was 168 per 100,000 population (95% confidence interval [95% CI] 138-204), with a progressive increase up to the 80-89 age group. Using "tracer" methodology, the estimated crude point prevalence rate was 196 (95% CI 163-235), with an overestimation of the prevalence in older patients and women and an underestimation in younger and less seriously affected cases.
