Differentiating between physical and psychological causes of confusion and psychosis poses a significant challenge to clinicians across all disciplines of medicine. This case report explores the clinical presentation and diagnostic journey of an adolescent girl. She presented to the emergency department with acutely altered behaviour and went on to re-present on multiple occasions over the following months with symptoms suggestive of psychosis. The team faced diagnostic difficulty differentiating between organic and non-organic causes of altered behaviour and mental state. This article explores the challenge faced by the team during the assessment and diagnosis of this patient.
