Consultation-Liaison Case Conference: Overcoming Bias in the Differential Diagnosis of Psychosis.

We present the case of a 34-year-old Black patient with no significant psychiatric history who presented with catatonia and psychotic symptoms following a recent severe acute respiratory syndrome coronavirus 2 infection, whose diagnosis of coronavirus disease 2019 encephalitis was delayed by premature attribution of his symptoms to a primary psychiatric etiology. Top experts in the consultation-liaison field provide guidance for this commonly encountered clinical case based on their experience and a review of the available literature. Key teaching topics include the diagnosis and management of coronavirus disease 2019 encephalitis, cognitive bias, and racial bias. Specifically, this case illustrates the role of the consultation-liaison psychiatrist in identifying medical conditions that may overlap with psychiatric presentations and in advocating for marginalized patients.
