Psychosis is a relatively infrequent but potentially serious and debilitating consequence of traumatic brain injury (TBI), and one about which there is considerable scientific uncertainty and disagreement. There are several substantial clinical, epidemiological, and neurobiological differences between the post-traumatic psychoses and the primary psychotic disorders. The recognition of these differences may facilitate identification and treatment of patients whose psychosis is most appropriately regarded as post-traumatic. In the service of assisting psychiatrists and other mental health clinicians in the diagnosis and treatment of persons with post-traumatic psychoses, this article will review post-traumatic psychosis, including definitions relevant to describing the clinical syndrome, as well as epidemiologic, neurobiological, and neurogenetic factors attendant to it. An approach to evaluation and treatment will then be offered, emphasizing identification of the syndrome of post-traumatic psychosis, consideration of the differential diagnosis of this condition, and careful selection and administration of treatment interventions.
