Evaluation and treatment of psychosis after traumatic brain injury.
A review of research studies to date suggests that psychosis is a relatively rare, but serious, complication of traumatic brain injury (TBI). Psychotic syndromes occur more frequently in individuals who have had a TBI than in the general population. Onset of symptoms can be early or late. Psychosis can occur during the period of post-traumatic amnesia, in association with post-traumatic epilepsy, in association with TBI-related mood disorders, and as a chronic, schizophrenia-like syndrome. TBI can interact with genetic vulnerability to increase the risk of developing illnesses such as schizophrenia. Thorough diagnostic assessment is the foundation of rational and effective pharmacotherapy for psychosis after TBI. Atypical antipsychotic drugs have emerged as first line drugs for treatment of psychotic disorders from all causes, including TBI. Anticonvulsant, antidepressant or other drugs may also be needed in some cases. Medication approaches must be adjusted for the particular characteristics and vulnerabilities of the patient with a TBI.
