Introduction: Schizophrenia represents a risk factor for violent behavior , even escalating to murder. Objectives: The current study aims to provide information regarding the prevalence and types of criminal acts committed by schizophrenic patients and identifying the precipitating factors. Aims: The purpose of this study is to obtain an overall view on the peculiarity of criminal behavior in schizophrenic patients in order to create efficient means of prediction and prevention. Methods: The current study collected all the data from Medline PubMed , from articles published between 2004-2014, by searching key words like violent behavior, schizophrenia, schizophrenia and criminality. Results: Schizophrenia spectrum disorders are usually associated with a substantially increased rate of violent crimes, in comparison to the general population. The risk factors include the same as in the general population, with a social and family background, and also specific risk factors found in schizophrenic patients like delusional and hallucinatory elements which drive patients to perform criminal actions. Conclusions: The criminal behavior manifested in schizophrenic patients shows certain features, especially at a motivational level, emphasizing the need for the early detection of delusional and hallucinatory symptoms that drive patients to do act of crimes, in a close relationship to the social cultural and also family context that creates their background.

IntroductionSuicidal behaviour represents a global public health issues; personal suicidal history is the most common predictor of the persistence and recurrence of suicidal ideation and behaviour in general.ObjectiveThis paper proposes to elaborate a synthesis of the scientific literature, concerning the main predictive factors of the persistence and recurrence of suicidal behaviour, considering that the current diagnostic criteria available fail to make a distinction and to specify clearly the differences between all psychiatric disorders without self-harming behaviour and the same nosological entity accompanied by suicidal behaviour.Materials and methodsI conducted a literature review, by analyzing the data concerning the predictors of the persistence and recurrence of self-harming behaviour, obtained from articles published between January 2013 and January 2015. I browsed the PubMed website, by keywords such as suicide, suicidal risk, suicide predictor, persistent suicidal ideation, and suicidal behaviour recurrence.ResultsThe scientific literature underscores that that entrapment and defeat are two elements often neglected; however, they should be a priority criterion, alongside traditional predictive factors, such as the following: gender, age, history of suicide attempts, socio-familial status, etc. All of these factors must be considered within the complex endeavour of assessing suicidal risk. However, there is still only scarce validated data concerning the mechanism that leads to entrapment and the one that determines its relation with self-harming behaviour.ConclusionsThis paper proposes to synthesize the current data concerning suicide predictors, in order to obtain new research assumptions. The final purpose is to develop proper preventive and therapeutic approaches.Disclosure of interestThe authors have not supplied their declaration of competing interest.
