Abstract
Psychotic symptoms are not uncommon in patients with Parkinson's disease (PD). Several studies have evaluated the prevalence of psychotic symptoms in PD. Psychosis in PD can either occur independently or due to the effect of dopaminergic antiparkinsonian drugs or as a part of behavioral and psychological symptoms of dementia with PD. Often, it is difficult to manage psychosis in PD as there are very few pharmacological agents which can be used with relative safety. Effective management includes early identification of symptoms, ruling out other differential diagnoses, using appropriate psychopharmacological agents along with proper psychoeducation, and applying nonpharmacological strategies. In this report, we report the case of an 84-year-old woman with PD who developed dementia and psychosis during her illness and discuss the various challenges in managing psychosis in patients with PD.
