title: Differential diagnosis of paralysis agitans.
abstract: Paralysis agitans may be mimicked by other disease processes and drugs which disturb the structural or functional integrity of the dopaminergic nigrostriatal system. In another group of patients, isolated symptoms or signs such as tremor or increased muscle tone are considered out of the context of the total clinical picture and may suggest parkinsonism.
