Abstract

Dopamine is the main agent for the cause of Parkinson's disease. Parkinson's disease is progressive neurodegenerative disorder which is affected mainly to the people above the age of 50 years. Dopamine is a neurotransmitter which initiates our movement. In a patient with Parkinson's disease there is a loss of this dopamine in the substantia nigra of the brain. Hence the person loss its coordination between brain and muscle movement. As a result of which they have disturbed gait patterns and also results in tremor. The tremor is mainly found in their hands and legs. There are many environmental and genetic factors for Parkinson's disease. Research and clinicians are working in these aspects. There are many modern treatments like brain stimulation to control this disease. Drugs containing Levadopa are generally given to Parkinson's disease patient. Levadopa initiates in increasing the dopamine level. This paper emphasizes on the impact of dopamine in Parkinson's disease.
