Le statut socio-économique et la prise de poids sous psychotropes

Publié le 12.07.2021

Le Centre de neurosciences psychiatriques montre que les patients avec un statut socio-économique faible débutant un traitement psychotrope ont un risque accru de développer des effets secondaires métaboliques (prise de poids, syndrome métabolique).

Le groupe de recherche du Prof. Chin B. Eap du Département de psychiatrie (CHUV-UNIL) a publié le 26 juin 2021 un article dans la revue scientifique internationale Translational Psychiatry. Cette étude a été effectuée chez des patients suivis en psychiatrie recevant des traitements pouvant induire des effets secondaires métaboliques, tels que prise de poids, diabète, hypertension ou taux de cholestérol très élevé. Elle montre, notamment, que les patients ayant un statut socio-économique faible ont un risque accru de développer ces effets secondaires au cours d’une année de traitement, par rapport aux patients avec un statut socio-économique élevé. Ainsi, ce travail montre que les inégalités socio-économiques sont partiellement responsables des différences de susceptibilité à l’apparition d’effets secondaires métaboliques. Une attention à ce facteur devrait être accordée lors de la prescription de psychotropes.

Lactate reveals all about its antidepressant prowess

Depression is the leading cause of disability worldwide. The Laboratory on Neurobiology of Depression of the Center for Psychiatric Neuroscience (Jean-Luc Martin, Pierre Magistretti and Anthony Carrard) has demonstrated that lactate, a molecule produced by the body during exercise, has an antidepressant effect in mice. Lactate is best known for the pivotal role it plays in the nutrition of neurons inside the brain. Yet it can also counter the inhibition of the survival and proliferation of new neurons, a loss seen in patients suffering from depression and in stressed animal. Furthermore, the research team pinpointed NADH as a vital component in the mechanism: this is a molecule with antioxidant properties that is derived from the metabolism of lactate. The findings were published in the scientific journal Molecular Psychiatry.


Nicolas Toni's Lab receives funding from the Synapsis Foundation for the work of Kevin Richetin

Worldwide, cases of age-related dementia are projected to reach 152 million in 2050, but the lack of tools to predict whether the brain will age in a healthy or pathological manner hinders the development of therapies. This project funded by the Synapsis Foundation proposes to support the development of methods for early diagnosis of different forms of dementia associated with Tau aggregation (tauopathies). The project will benefit from the synergy of two departments of the Lausanne University Hospital (CNP and CLM).
