He concluded that damage of the substantia nigra is invariably accompanied by rigidity and tremor (and, if unilateral, that the effect was crossed) except when hemiplegia or poliomyelitis coexisted or when the patient was in extremis. Reviews of the literature5-21 conducted since that time have substantiated a high positive correlation between nigral lesions and parkinsonism, but Trétiakoff's unitary theory of causation of parkinsonism has not been universally accepted because ( 1 ) neuropathologic changes have been
