“…Using the sample of 248 men with schizophrenia described above, we found that clinical ratings of deficient affective experience (shallow affect, callousness, lack of remorse and a failure to accept responsibility for one's own actions) was associated with violent offending and with negative symptoms, but not with CD or substance misuse (Sunak 2006). Similarly, in a study of persistently aggressive inpatients, three distinct groups were identified, one of which was characterized by a lack of remorse (Nolan et al 2003). We hypothesize that among patients with schizophrenia, deficient affective experience may be a state that fluctuates as do psychotic symptoms, and that when present it increases the vulnerability for aggressive behaviour towards others.…”

Robust evidence has accumulated showing that individuals who develop schizophrenia are at elevated risk when compared to the general population to engage in violence towards others. This violence impacts negatively on victims as well as perpetrators and poses a significant financial burden to society. It is posited that among violent offenders with schizophrenia there are three distinct types defined by the age of onset of antisocial and violent behaviour. The early starters display a pattern of antisocial behaviour that emerges in childhood or early adolescence, well before illness onset, and that remains stable across the lifespan. The largest group of violent offenders with schizophrenia show no antisocial behaviour prior to the onset of the illness and then repeatedly engage in aggressive behaviour towards others. A small group of individuals who display a chronic course of schizophrenia show no aggressive behaviour for one or two decades after illness onset and then engage in serious violence, often killing, those who care for them. We hypothesize that both the developmental processes and the proximal factors, such as symptoms of psychosis and drug misuse, associated with violent behaviour differ for the three types of offenders with schizophrenia, as do their needs for treatment.

“…In previous papers, aggression had been categorized as ofensive and defensive such as a dangerous or evasive response to a sense of fear, the most frequently preferred classiication in the recent literature categorized into three groups: impulsive, proactive (also known as organized, instrumental, or predatory), and psychotic. Impulsive aggression (54%) is the most common category followed by proactive aggression (29%), and psychotic aggression (17%) [27,28]. As predicted, psychotic aggression is a process related to positive symptoms of psychosis, such as hallucinations or delusional content.…”

Serotonin - A Chemical Messenger Between All Types of Living Cells

Serotonin is a neuromodulator that has a critical role on the regulation of essential events in neuronal and glial development, such as cell proliferation, diferentiation, migration, apoptosis, and synaptogenesis, and acts as a developmental signal. It has been known that a serotonergic system is associated with many psychiatric disorders. The serotonergic system also predominates on the etiopathogenesis of two important endophenotypes: impulsivity and aggression. Impulsiveness is deined as personality trait and an implusive temperament is associated with clinical conditions such as pathological gambling, eating disorders, and borderline personality disorder as well as being a risk factor for self-harm, suicide, and emotional liability. Aggression is not a personality trait like impulsivity, but it is the behavior of harm or injury to others. Besides being a natural human behavior toward survival, aggression can be harmful to the individual and the community when it is constant and excessive. In this chapter, we aimed to review the role of the serotonergic system on impulsivity and aggression, which are two important endophenotypes that identiied in many psychiatric disorders.

ÖzetPek çok psikiyatrik hasta şiddet eğilimi sergilememekte ise de günümüz toplumunda ruhsal bozukluk ve şiddet biribiyle bağlantılı görülmektedir. Genel populasyon ile kıyaslandığında şiddet davranışı riski şizofrenide istatistiksel olarak anlamlı bir yükseklik göstermiştir. Şizofrenide şiddet davranı-şı riski madde kullanım eştanılılığı ile artmaktadır. Şizofreni tanılı yetişkinlerde şiddet davranışının ortaya çıkması, antisosyal kişilk bozukluğu ve şizofreninin akut psikopatolojisi ile ilişkili iki farklı yol izlemektedir. Klozapin şizofrenide şiddet davranışı tedavisinde en etkin tedavidir. Son kanıtlar olanzapini ikinci sıraya yerleştirmiştir. Tedavi uyumu son derece önemlidir. Farmakolojik olmayan tedavi yöntemleri giderek artmaktadır. Tek başına farmakoterapinin yetersiz kaldığı olgularda, bireysel davranışçı yöntemler etkili olmaktadır.Anahtar sözcükler: Şizofreni, şiddet, madde kötüye kullanımı, eştanı. AbstractAlthough most psychiatric patients are not violent, serious mental illness is associated with increased risk of violent behavior. There is statistically significant increase in risk of violence among patients with schizophrenia in comparison with general population. The risk of violence in schizophrenia is increased by comorbid substance use disorder. Violence among adults with schizophrenia may follow at least two distinct pathways; one associated with antisocial conduct, and another associated with the acute psychopathology of schizophrenia. Clozapine is the most effective treatment of violent behavior in schizophrenia. Emerging evidence suggests that olanzapine may be the second line of treatment. Treatment adherence is of key importance. Non-pharmacological methods of treatment of violence in schizophrenia are increasingly important. Cognitive behavioral approaches appear to be effective in cases where pharmacotherapy alone does not suffice.

Characteristics of Assaultive Behavior Among Psychiatric Inpatients

Abstract: Information obtained from interviews with assailants can reveal the underlying causes of specific assaults. This information is potentially useful in the selection of rational antiaggressive treatment strategies.
