[Relationship between homicide and mental disorders].
OBJECTIVE
Several studies have found a relationship between severe mental disorders and violence. One of the approaches to study this theme are investigations with homicide offenders. The aim of the present article was to investigate the association between homicide and mental disorders.


METHODS
A review of the literature was made through the following databases: Medline, Scientific Eletronic Library Online and Lilacs. In the Medline system, it was also searched the related articles section.


RESULTS
Although there is an association between mental disorders and homicide, it is not clear why some patients behave violently and others do not. Comorbid alcohol/drugs disorders and personality disorders and lack of adherence to treatment may increase this risk.


CONCLUSIONS
Identifying people with risk of violence and offering them mental health treatment services is warranted. These services should prevent the loss of contact and non-compliance with treatment that frequently precede homicide committed by people with severe mental disorders. It is of utmost importance that society and governmental authorities decrease the barriers that limit access to psychiatric and psychosocial treatment.
