Did You Know (DYK)? Parkinson-Disease Psychosis & Treatment Options

While Parkinson's Disease (PD) is traditionally considered a motor system disorder based on the hallmark features of tremor, rigidity, and bradykinesia, PD is now recognized to be a complex disorder involving a wide range of nonmotor manifestations that contribute to disability. Psychosis, not motor dysfunction, is the single greatest risk factor for nursing home placement in patients with Parkinson's Disease. 

Parkinson's Disease Psychosis (PDP), characterized most often by visual hallucinations and paranoid delusional ideations, can be one of the most debilitating nonmotor symptoms of PD as disease progresses. 

This month's DYK from LeadingAge Ohio Partner, HealthDirect Pharmacy Services, covers early clinical manifestation and causes of PD psychosis in these patients with recommendations for reducing episode frequency and severity of psychosis symptoms through medication management and intervention when indicated.
