Abstract

Purpose of Review: We discuss features of Parkinson’s disease psychosis (PDP) including symptomology and pathophysiology. Treatment options, including non-pharmacologic strategies, dose reduction of offending agents, and the addition of non-dopaminergic antipsychotics, are addressed. The efficacy of second-generation antipsychotics and novel agents is examined. Recent Findings: Pimavanserin, a 5-HT2A/C receptor inverse agonist with no other receptor activity, has shown efficacy and tolerability and is now FDA approved for PDP treatment. Research into novel targets is ongoing. Summary: PDP is a morbid complication of Parkinson’s disease with complex incompletely understood mechanisms. Treatment is directed towards mitigation of psychosis without worsening of motor features.
