ABSTRACT
New criteria for Parkinson's disease-associated psychosis (PDAP) were recently proposed by a NINDS-NIMH working group. We assessed 116 consecutive unselected outpatients with PD for the existence of psychotic symptoms during the previous month, using a structured questionnaire covering the whole spectrum of PDAP symptoms. Hallucinations occurred in 42% of the patients (visual 16%; nonvisual 35%), delusions in 4%, and minor symptoms in 45% (sense of presence, visual illusions, or passage hallucinations). The prevalence of PDAP was 43% when the usual definition was used (hallucinations and/or delusions) and 60% when the NINDS-NIHM criteria were used. Correlations between PDAP and patient characteristics varied with the definition of PDAP. These findings suggest that the epidemiology of PDAP should be re-evaluated with the new criteria. Minor symptoms and nonvisual hallucinations are an important part of the PDAP spectrum, which has commonly been restricted to visual hallucinations and delusions.
