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.

Suicide is one of the leading causes of death in the world, and depression is among the top causes of morbidity and mortality at international level. The main complication of any depression is precisely suicidal behavior, with all its facets. The present work is a succinct study aimed at highlighting the main categories of motivations that lead to suicidal behaviors in the spectrum of depression. The group of patients selected for this study presents all possible variants of diagnoses in the spectrum of endogenous depressions. The research reveals data on psychotic motivation, motivations in the socio-familial and professional sphere, as well as the correlation between the present suicidal behavior and the clinical form of depression. The fi ndings emphasize once again the imperative need not to neglect any of the symptoms of depression, from anxiety to delusional hallucinatory phenomena, in correlation with the patient's entire bio-psycho-social context, to support the prevention of any form of suicidal behavior.

In both adults and pediatric population, depression is a major disability cause; suicide is the third death cause among children and adolescents. Whereas depression and depression with associated anxiety are among the most common psychiatric pathologies in children and adolescents (with strong impact on their global functionality and with a significant influence on their development process), they are far from studied thoroughly. This study aims to highlight certain demographic and clinical patterns associated to depression of anxiety in children and adolescents, which may represent premises for broader future research and for the consolidation of primary, secondary, and tertiary prevention methods.
