Parkinsons disease

Parkinson's disease, a movement disorder, is a progressive neurological disorder, the condition progresses over time. In Parkinson's disease, the cells which are responsible to secrete dopamine begin to die. Dopamine is responsible for the smooth functioning of the muscle of the body. Dopamine is secreted by the cells of the substantia nigra, a part of the brain.

Parkinson's disease symptoms including the change in voice, slurry voice, tremor, slow movements, anosmia, balancing problem, stiffness of arms, legs and trunks, facial expression start to change, and loss of sense of smell. These symptoms are due to a decrease in levels of dopamine leading to abnormal brain activity.

The cause which leads to low levels of dopamine is not yet clear. But there are many factors which lead to Parkinson's disease, maybe genetic factors and environmental causes. As there is no specific test to diagnose Parkinson's disease, a dopamine transporter test scan can be used.
