Novel case of Parkinson’s disease and schizophrenia: challenges in the management


Coexistence of idiopathic Parkinson’s disease (iPD) and schizophrenia can pose great diagnostic and therapeutic challenges because of their pathophysiology. Our case highlights such challenges in management. We present a case of 73-year-old man who had parkinsonism for last several years and was also diagnosed with schizophrenia. Due to lack of collateral information about the onset of symptoms and clinical course, it was difficult to distinguish iPD from neuroleptic-induced parkinsonism. Even though, certain clinical findings may help to differentiate between the two conditions, single positron emission computerized tomography/DatScan was used to confirm the diagnosis of iPD. Treatment of coexisting iPD and schizophrenia can be challenging, and a delicate pharmacologic balance must be maintained to ensure adequate symptomatic control. Current evidence suggests that clozapine is a better choice for managing psychosis in these patients due to its unique receptor profile and better safety data.
