Comorbidité entre la dépression et l’addiction

Abstract: > La dépression est le trouble mental le plus souvent associé aux addictions. La prévalence de la dépression parmi les patients souffrant d'une addiction est de 30 %. Cette forte comorbidité suggère l'existence de voies moléculaires et anatomiques communes à ces deux pathologies. C'est le cas du noyau accumbens (NAc) dont le dysfonctionnement est impliqué dans la dépression et l'addiction. Nous résumons ici des résultats récents montrant que la protéine p11 (S100A10) dans le NAc permet de réguler des comportem… Show more

“…Given that these two disorders can be treated by common NAc-targeting therapies, this may indicate that they have the same or similar pathogenesis. Therefore, the NAc remains a central and critical area to elucidate the common or similar underlying molecular mechanisms of addiction and depression (Arango-Lievano and Kaplitt, 2015 ). In this review article, we will discuss the neuroanatomical profile and the neural circuits of the NAc as a potential explanation for the comorbidity of addiction and depression.…”

“…Risky decision-making is a characteristic of depression and of addictive disorders, including problem gambling123456789. However it is not clear whether predisposition towards risky choices increases the likelihood of depressive disorders, whether the converse is the case, or whether the two traits are independently associated to a third factor.…”

“…Chronic stress can lead to a variety of psychological alterations, including anxiety-depression and alcohol intake. In a great body of epidemiological surveys, stress-induced psychopathologies co-occur as comorbidities at high rates [1] . Stressors like threatening situations trigger serial neuroendocrine events orchestrated by systems of stress with the hypothalamic-pituitary-adrenal axis (HPA) considered as the main actor.…”
