Abstract
Introduction: Drug-induced parkinsonism (DIP) is one of the most common iatrogenic movement disorders. It is characterized by tremors, slowness of movement, and shuffling gait with postural instability, clinically indistinguishable from idiopathic Parkinson's disease. Prior exposure to antipsychotic medications or other dopamine receptor blocking agents (DRBAs) is required for the diagnosis.
Areas covered: This article aims to review the epidemiology, pathophysiology, clinical features, ancillary testing, and treatment of DIP. A literature search was undertaken in PubMed from January 2013 to January 2024.
Expert opinion: A clinician's suspicion of DIP must always be present when a patient develops acute to subacute onset of parkinsonism while taking a DRBA. As DIP can be indistinguishable from idiopathic PD, ancillary testing, such as DaTscans and skin biopsy searching for alpha-synuclein deposits, are often required to make a definitive diagnosis. When DIP develops, steps should be taken to discontinue the offending agent or, in the case of antipsychotics, dose reduction or change to an agent with lower risk for DIP, such as quetiapine or clozapine. Prophylactic treatment with anticholinergics is not indicated.
