Diagnosis of mental illness (MI) inconsistently predicts aggressive behavior although co-occurrence of substance use appears to increase the frequency of aggression in MI populations. We propose that alcohol use should moderate the relationship between mental disorders marked by deficits in self-control and aggression and victimization. In the present study, alcohol use, physical aggression perpetration, physical aggression victimization, injury and psychiatric symptoms were assessed in a sample of 297 substance use disorder patients (102 women; = 38.

Various epidemiological and biological evaluations and the recent publication of the DSM-V (diagnostic and statistical manual of mental disorders) has imposed on the scientific community a period of reflection on the diagnosis and treatment of what in the DSM-IV was defined as "addiction". To date, the term "addiction" has been replaced by the DSM-5, because there is no global scientific consensus that has unequivocally characterized its clinical characteristics. This, we will talk about substance/alcohol use disorders (SUDs/AUDs) and disorders related to behavioral alterations (DBA) that can generate organic diseases, mental disorders, and social problems.

ABSTRACTObjectives:Errorless learning is a promising rehabilitation principle for learning tasks in patients with amnesia, including patients with Korsakoff's syndrome. Errorless learning might possibly also contribute to decreases in behavioral and psychiatric problems, as patients in long-term care facilities become more independent after training. The aim of this study was to examine the effects of errorless learning on potential changes in psychotic and affective symptoms, aggression and apathy, in contrast with a control group who received care as usual.

Hallucinations constitute one of the 5 symptom domains of psychotic disorders in DSM-5, suggesting diagnostic significance for that group of disorders. Although specific featural properties of hallucinations (negative voices, talking in the third person, and location in external space) are no longer highlighted in DSM, there is likely a residual assumption that hallucinations in schizophrenia can be identified based on these candidate features. We investigated whether certain featural properties of hallucinations are specifically indicative of schizophrenia by conducting a systematic review of studies showing direct comparisons of the featural and clinical characteristics of (auditory and visual) hallucinations among 2 or more population groups (one of which included schizophrenia).
