Neuroimaging and Neurocognitive Correlates of Aggression and Violence in Schizophrenia

Abstract EN

Individuals diagnosed with major mental disorders such as schizophrenia are more likely to have engaged in violent behavior than mentally healthy members of the same communities.

Although aggressive acts can have numerous causes, research about the underlying neurobiology of violence and aggression in schizophrenia can lead to a better understanding of the heterogeneous nature of that behavior and can assist in developing new treatment strategies.

The purpose of this paper is to review the recent literature and discuss some of the neurobiological correlates of aggression and violence.

The focus will be on schizophrenia, and the results of neuroimaging and neuropsychological studies that have directly investigated brain functioning and/or structure in aggressive and violent samples will be discussed as well as other domains that might predispose to aggression and violence such as deficits in responding to the emotional expressions of others, impulsivity, and psychopathological symptoms.

Finally gender differences regarding aggression and violence are discussed.

In this context several methodological and conceptional issues that limited the comparison of these studies will be addressed.
