Paralysis agitans is a term initially introduced in 1817 by the British physician, James Parkinson, and literally means “shaking palsy.” It refers to a progressive degenerative disorder of the central nervous system caused by the loss of dopamine-producing brain cells in the substantia nigra and characterized by postural instability, bradykinesia, rigidity, and tremors. This disorder became known as Parkinson’s disease in the 1860s.
