Parkinson's disease
Parkinson's disease (paralysis agitans or PD) is a neurodegenerative disease of the substantia nigra, an area in the basal ganglia of the brain. The disease involves a progressive disorder of the extrapyramidal system, which controls and adjusts communication between neurons in the brain and muscles in the human body. It also commonly involves depression and disturbances of sensory systems.
