• ABSTRACT
    • Evaluating the patient with first episode psychosis (FEP) requires a careful assessment that includes a thorough history, examination, and workup. This begins with a thoughtful consideration of the differential diagnoses and is followed and supported by laboratory, encephalographic, and imaging studies where appropriate. This article presents some of the diagnostic considerations for a patient presenting with psychosis with an emphasis on the secondary causes and proposes a tiered approach to the workup of FEP that is clinically guided.
