Schizophrenia and Crime: Factors That Contribute to AggressionSchizophrenia is a psychiatric disorder occurring in the brain that is characterized by positive symptoms such as hallucinations and delusions, but may also present with negative symptoms like lack of emotional expression and catatonia, or inability to move. Social problems, such as difficulty establishing and maintaining interpersonal relationships, are also symptoms that can lead to the diagnosis of this disease (Tandon et al., 2013). Additionally, schizophrenia has been associated with the production of aggressive behaviors that can lead to criminal acts (Hanlon, Coda, Cobia, & Rubin, 2012). The aim of this literature review is to investigate factors in schizophrenia that may contribute to aggressive behavior and, therefore, criminality. Factors that contribute to aggressive or violent behavior in some people with schizophrenia can actually be found at the very structural level. and the functional level of the brain. Several deficiencies in the brain structure of a person with schizophrenia lead to abnormal functioning, which in turn can lead to a higher likelihood of aggression. Comorbidity, the presence of two disorders at the same time, schizophrenia with other disorders can also lead to crime. Abnormal brain function in a schizophrenic patient can cause paranoid or persecutory delusions. These delusions are common features of schizophrenia and lead to criminal behavior (Hanlon et al., 2012). Several possible correlations have been established between the biochemical factors of schizophrenia and criminal behavior. Not only are there biochemical differences between people with schizophrenia and those without schizophrenia, but in the middle of the article... schizophrenia is more likely to have inappropriate behavioral responses ("Schizophrenia", 2009) . The association of mental illnesses with criminal activity is attributed to the observation that a non-overwhelming, but notable, percentage of incarcerated or incarcerated people suffer from mental illnesses. Mental disorders that can become very serious if left untreated or inadequately treated, such as schizophrenia, can be found among individuals in the criminal justice system who have committed crimes ranging from misdemeanors to felonies. Although people with schizophrenia may have committed non-violent crimes, violent crimes, such as disturbing the peace by shouting or appearing threatening, domestic violence, and murder, could be due to several factors that show that people with schizophrenia have a higher risk of aggressive behavior. behavior (National Alliance on Mental Illness [NAMI], 2008).
