[Non-motor symptoms of Parkinson disease. Significant impact on quality of life--using possible treatments].

In patients with idiopathic Parkinson's disease, not only the motor disorders, but also disturbances of the autonomic nervous system and the psyche need to be treated. With respect to the autonomic nervous system, such symptoms as hypersalivation, seborrhea, dysregulation of the cardiovascular system, disturbances of the gastrointestinal tract and bladder motility, as also sleep disorders predominate. Also seen in Parkinson's disease are such psychiatric complaints as depression, dementia and psychoses, which latter in particular may also be a consequence of dopaminergic replacement therapy. A number of therapeutic concepts are available for the treatment of these disorders, which are often extremely stressful for the patient and therefore require early treatment.
