Vers un modèle développemental d’épigenèse probabiliste du trouble des conduites et des troubles externalisés de l’enfant et de l’adolescent

Abstract: Some recent controversies have highlighted that a genetic or a neuropsychological determinism was the view that dominated the debate in the field of the etiopathological understanding of externalised disorders in the scientific community. Based on a review of the recent literature, I will show that other views are trying to integrate the diversity and the complexity of the factors that influence these behavioural manifestations. The model that better encompasses this complexity is a developmental model of probabilistic epigenetic. In this paper, I summarize several lines of studies that support this model. To this purpose, I will leave the categorical approach of the psychiatric nosography, to adopt a dimensional approach of the phenomenology that will help to follow and focus on specific pertinent dimensions such as clinical signs, temperamental and psychological characteristics, environmental and/or genetic factors in order to study their interactions and their possible developmental product. This model also permits a specific temporal focus on early interactions that many consider as crucial in terms of developmental cues. [Copyright &y& Elsevier]
