[Autonomic disorders in parkinsonism]

The authors analyze the clinical and paraclinical manifestations of vegetative disorders in parkinsonism. It is shown that vegetative disorders are relatively independent of motor parkinsonism manifestations and run their course by the type of concomitant sympathetic and parasympathetic insufficiency. Injury to the segmental and suprasegmental mechanisms of motor control underlies vegetative disorders. The role of segmental and suprasegmental disorders in degenerative diseases of the nervous system with marked vegetative manifestations is analyzed and compared.
