IntroductionPersonality disorders designate a series of personality traits involving a behavioural pattern characterized by the recurrent violation of social norms, the importance of medico-legal implications associated to personality disorders being incontestable.ObjectiveThis study aims to obtain a clear image regarding the particularities of violent behaviour, and also the mechanisms of anger in personality disorders, in relation with the legal implications of those reactions.MethodsThe present study is a synthesis of recent literature (2012-2014) regarding the role of anger in violent behaviour with legal implications, in personality disorders. The research was made on PubMed, by the following keywords: personality disorder; violence in personality disorders; anger.ResultsThe core element that determines violent behaviour is anger. The physical effects of anger include increased heart rate and blood pressure, as well as an increase in the level of epinephrine and norepinephrine. Therefore, anger can be considered an integrant part of the response to a potential aggression or a potentially dangerous environment. Several general circumstances can activate anger. A strong example in supporting this theory is the bidirectional relation between anger within personality disorders and the use of alcohol and psychoactive substances. The individual gets extra stimulation, including through their psychopharmacological properties, thus exacerbating anger.ConclusionsIn conclusion, it is necessary to conduct future studies focusing on the underlying causes of violence in personality disorders, as well as on the warning signs of potential violent acts, considering that personality disorders alone often cannot explain criminality.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Tulburarea afectivă bipolară devine o patologie tot mai frecventă în sfera pediatrică, ridicând numeroase probleme de diagnostic de certitudine cât şi diferenţial. De cele mai multe ori, criteriile standard ale bolii nu sunt întru totul îndeplinite la copil, fiind necesară o particularizare a acestora şi o mai exactă clasificare a tipurilor nosologice. Totodată, o problemă centrală este cea a diferenţierii şi/sau detectării comorbidităţii cu ADHD şi cu tulburările de conduită ale copilului.
