The forensic psychiatric aspects of schizophrenia

This review of the literature does seem to reveal an association between schizophrenia and a variety of antisocial behaviors that include violent crime, and even homicide, especially in North America. The literature consistently shows that since the 1950s, schizophrenics have been involved in crime and arrested more frequently than the general population, they are overrepresented in correctional settings, and they represent the majority of those found not guilty by reason of insanity. Many authors cite changes in mental health policies, particularly de-institutionalization, as one of the major causes of these phenomena. It is important to note that a history of prior arrests and of being male, poor, unskilled, uneducated, and unmarried are perhaps the best predictors of antisocial behaviors in the mentally ill and in the general population alike. Schizophrenic drift and increased family pathology in schizophrenic families, however, may predispose people suffering from schizophrenia to these demographic variables. Interestingly, these variables do not seem as relevant in the emergency room or inpatient wards where violence seems to be mainly affected by the severity of psychopathology, substance abuse, neurologic signs, and the environment within the mental health setting. The implications for the practice of psychiatry are diverse. Clearly clinicians in both hospitals and community mental health settings must have experience, training, and an awareness of the literature relating to the prevention, causes, and management of violence. It behooves us in the mental health field, having vociferously supported the community mental health movement, to assist police in the management of the mentally ill who are now in the community, perhaps by the use of mobile crisis intervention teams and by a considerably increased amount of effort and cooperation. Correctional services require urging to develop resources for identifying and tracking the mentally ill so as to be able to provide programs and continuity of care. Community mental health and criminal justice systems need to cooperate in planning the transition of mentally abnormal offenders from prisons into the community and then providing support and after-care for them. One exemplary program that has developed and benefited from the coordination and planning at the interministerial level is the Inter-ministerial Project (IMP) program in Vancouver. This program identified the people whose histories revealed repeated admissions to both correctional and mental health facilities, bouncing between one and the other. Using a case management approach with a limited caseload, clinicians were able to reduce the number of admissions to both types of facilities. This program should serve as a model for other jurisdictions.(ABSTRACT TRUNCATED AT 400 WORDS)
