Psychiatric disorders after traumatic brain injury (TBI) are frequent. Researches in this area are important for the patients' care and they may provide hints for the comprehension of primary psychiatric disorders. Here we approach epidemiology, diagnosis, associated factors and treatment of the main psychiatric disorders after TBI. Finally, the present situation of the knowledge in this fi eld is discussed.

O objetivo do presente estudo foi comparar pedidos de interconsulta psiquiátrica realizados para dois hospitais gerais universitários brasileiros e avaliar a aplicabilidade de um protocolo de registro de interconsulta psiquiátrica (PRISMe). Foi realizada análise dos pedidos de interconsulta, do PRISMe anexado a eles e o número total de pedidos de interconsulta incluídos na amostra foi 541 (438 pedidos de interconsulta do HCFMRP-USP e 103 pedidos de interconsulta do HU-UFSC). Observou-se maior freqüência de solicitação para pacientes do sexo feminino, caucasianos, entre 31 a 60 anos e casados. Os diagnósticos psiquiátricos mais freqüentes foram depressão, transtornos de adaptação e de personalidade. Os resultados estão de acordo com a literatura nacional e internacional e as diferenças encontradas podem ser atribuídas às diferenças na infra-estrutura das instituições e nos contextos sócio-econômicos nos quais estão inseridas. Achados do presente estudo demonstram a aplicabilidade do PRISMe e sugerem que podem facilitar a sistematização da obtenção de achados clínico-demográficos e a comparabilidade entre as diferenças.

Objective: To review the literature regarding the diagnosis of first-episode psychosis in the context of psychiatric emergency. Method: Review of empirical and review articles selected by electronic search in the PubMed database. Results: Specific features of emergency care -single, brief, and cross-sectional assessments with little information -may jeopardize the diagnostic process. These limitations can be circumvented by the application of operational diagnostic criteria, by the use of scales and structured interviews, and by short observation periods (24-72 hours). Diagnoses of bipolar disorder, schizophrenia, psychotic depression, and delusional disorder performed in the context of emergency have good stability, but the same does not apply to the diagnoses of brief psychotic disorder, schizophreniform disorder, and schizoaffective disorder. Firstepisode psychosis can occur in the course of the use of psychoactive substances and the persistence of psychotic symptoms even after cessation of the use of the substance is relatively frequent. The rational use of subsidiary tests may be of help in establishing the differential diagnosis of psychotic episodes due to general medical conditions. Conclusion: The diagnosis of first-episode psychosis can be adequately performed by psychiatric emergency services if evidence-based routines are implemented. Descriptors
