[Disorders of autonomic regulation in Parkinson syndrome]

Ever since the first description of Parkinson's disease, it has not only been associated with the classical triad of akinesia, rigor and tremor but also with autonomic regulation disorders. However, the studies published on this subject show differing and partly contradictory results. A large number of studies demonstrate a distinct autonomic disorder. On the other hand there are authors who question an affliction of the autonomic nervous system and others who attribute the autonomic disorder to Parkinson specific medication. To make matters worse, the various pathogeneses of Parkinson's syndrome within the patients collectives have not been sufficiently differentiated and nomenclature of the multisystem degeneration was handled in different ways. Taking our examinations of the various autonomic functions and the underlying literature into critical consideration, we come to the conclusion that regulation disorders of the cardiovascular system, gastrointestinal and urinary tract, as well as sweat and thermoregulation are often seen in the idiopathic Parkinson's disease. In our opinion the idiopathic Parkinson's syndrome must be attributed to the multisystem degenerations. Autonomic dysfunction occurs in different intensities in the disease.
