Parkinson's disease is a degenerative disorder of the central nervous system (CNS) that occurs due to the death of the dopamine generating cells located in the substantial nigra which is a region of the mid brain. The cause of the death of these cells is still unknown. This disease is named after an English doctor Mr. James Parkinson's who published the first detailed description of this disease in his report titled "An Essay on the Shaking Palay" in the year-1817.
April-11 (The birthday of James Parkinson) is observed for creating awareness about this disease through public awareness campaigns and using a red tulip as the symbol of this disease. The main motor symptoms affected by this disease are collectively called the Parkinsonism or a "parkinsonian syndrome".
