Parkinsons disease

Parkinson’s disease is one of the well-known age related neurodegenerative disorder, second in recurrence just to Alzheimer's disease. Parkinson’s disease also causes extensive injury of the motor or sensory pathways extending beyond the pigmental brain stem nuclei. Although the disease symptoms can be controlled by Levodopa but the etiology of the Parkinson’s disease remains obscure. In the United States half a million of people are diagnosed as having PD and it is predicted to be triple over next 50 years. PD appears to be slightly more in men than in women usually ranging from 1.2:1 ratio upto 1.5:1.
