Intérêts et limites de l’approche biologique pour l’étude des comportements agressifs

The complexity of violent behaviours (self or towards another person) implies multidimensional facets. Biology and neurosciences help to understand these phenomena.This work is a critical review of scientific literature in this area. Our goal is to underline elements implicated in criminal or suicidal behaviours.We describe : 1 - the main nervous structures involved, 2 - researchs on neuromediators, 3 - the influence of hormones, 4 - genetic outcomes, 5 - Acquired biological factors.     

Influence de l’insight sur l’efficacité de l’entretien motivationnel dans la prévention des rechutes chez des patients alcoolo-dépendants

Motivational interventions are effective in the treatment of alcoholism, especially in the early stages of the Prochaska and DiClemente model of change. In 62 alcohol dependent patients without cognitive disorders, in addition to treatment as usual, motivational interviewing effectiveness on relapse prevention was linked with the level of insight. We have retrieved a moderate effectiveness on relapse prevention in patients with poor insight and a significant adjunctive effectiveness in patients with good insight.
