Summary: The aim of this study was to examine the relationship between peripheral inflammatory markers and aggression and impulsivity in schizophrenia patients with and without criminal histories. The results showed that inflammatory agents were significantly increased in forensic schizophrenia patients with high aggression scores, suggesting a potential link between inflammation and violence and criminal behavior.

Summary: This study investigated the relationship between violent behavior and neurocognitive function in Chinese patients with schizophrenia. The results showed that 10.4% of patients exhibited violent behavior, and these patients had higher symptom and cognitive function scores. Gender, illness duration, smoking, severity of illness, and language ability significantly contributed to the development of violent behavior in schizophrenia patients.

Summary: This study investigated the characteristics and associated factors of violence in male patients with schizophrenia in China. The results showed that the violent patients had lower education levels, longer duration of illness, higher rates of hospitalization, history of suicide attempts, and history of alcohol compared to the non-violent patients. Regression analysis revealed that previous suicidal behavior, antisocial tendency, young age at violent incident, impulsivity, and relationship instability were risk factors for violence among male patients with schizophrenia.

Summary: This study examined the impact of reasoning ability, psychomotor speed, and self-rated psychopathy on emotion recognition in individuals with psychotic spectrum disorders (PSD) with and without a history of aggression, as well as in healthy individuals. The results showed that reasoning ability, psychomotor speed, patient status, and prior aggression were associated with accuracy in emotion recognition. However, self-rated psychopathy was not independently linked to emotion recognition when considering these factors.

Summary: Psychotic disorders are unevenly distributed by race in the United States. Hispanic and Black respondents reported higher rates of psychotic experiences, with hallucinations more commonly reported by the Hispanic respondents. These racial disparities in psychotic experiences are explained by socioenvironmental risk factors such as income, education, urban/rural living, discrimination, and trauma exposure.

Summary: This study investigated EEG microstates in violent patients with schizophrenia. The results showed differences in EEG microstate parameters between violent and non-violent patients, which could help clinicians identify schizophrenia patients with a risk for violence and develop early intervention strategies.

Summary: Although most persons with a schizophrenia-spectrum disorder are not aggressive, a minority is at higher risks to commit violent acts, especially in forensic settings. This study assessed the association between self-report questionnaires, neuropsychological tests, and olfactory functions in inpatients of a maximum-security hospital, and found that impulsivity, attention deficits, and odor identification were predictive factors for institutional violence in forensic settings.

Summary: People with schizophrenia are often victims of violence, which is associated with recent victimization, childhood abuse, social background, and mental health symptoms. Some victims also exhibit violent behavior, which is related to baseline violent behavior and frequent interactions with close friends.

Summary: This study explored disrupted resting-state activity and functional connectivity in schizophrenia patients with a history of violence. The results showed that brain regions associated with emotion regulation exhibited impaired functional connectivity in schizophrenia patients, and this impairment was associated with violent antecedents among patients.

Summary: The risk factors for violent behavior in schizophrenia spectrum disorders may differ depending on whether it occurs before or after the onset of the disorder. A study conducted in the Netherlands found that patients with violent behavior before the onset of schizophrenia more often lived in socially disorganized neighborhoods, while patients with violence after onset had higher prevalence of clinical risk factors such as substance misuse, impairments in executive functions, poor impulse control, delusions, and lack of illness insight.

Summary: The study found that income levels were differentially related to total grey matter volume in schizophrenia patients and controls in Latin America. There was also a distinct relationship between brain structure and income levels among the two groups.
