[Mental suffering IN patients with parkinsonism].

Comprehensive treatment of patients with parkinson's disease demands that not only motoric dysfunctions but also psychosocial aspects have to be considered. The scope of this review is to cover not only the frequent dementia and depressive states associated with this disease, but also the drug-induced behavioral abnormalities, insomnia, conflicts with those providing care and implications for professional activities. The fundamental pathophysiological and psychopathological mechanisms are explained and illustrated by examples.
