Visual hallucination, Differential diagnosis, Decision tree


Differential diagnosis of the etiology of visual hallucinations is challenging. Although visual hallucinations can be symptomatic of psychiatric disorder, they more commonly indicate neurological or medical disorders, sensory impairment, or substance intoxication or withdrawal. Accurate diagnosis and treatment is crucial given that misdiagnosis and incorrect treatment intervention can have profound consequences. The purpose of this paper is to summarize the most prevalent causes of visual hallucinations, review the DSM-5 hallucination decision tree, and provide an annotated visual hallucination differential diagnosis decision tree.
