Abstract
La depresión supone uno de los problemas de salud mental de mayor incidencia en la población, generando grandes costes económicos, sociales y humanos para la sociedad, además de presentar una alta comorbilidad con otros desórdenes emocionales y una elevada tasa de mortalidad (Paykel et al., 2005). La naturaleza familiar del trastorno depresivo mayor ha sido confirmada a través de diversos estudios y se ha planteado como un trastorno parcialmente causado por componentes genéticos (Gershon, 1982; Odgerel et al., 2013; Sullivan et al., 2000) y sus interacciones con las condiciones ambientales (Disner et al., 2011; HEATH et al., 1999; Vázquez C. et al., 2010). Por ello, se ha considerado que personas con historia familiar de depresión tienen mayor posibilidad de presentar endofenotipos depresivos (Odgerel et al., 2013).En general, el trastorno depresivo mayor (en adelante MDD) es tratado como un desorden afectivo caracterizado por un procesamiento alterado de la información emocional. Por ello, las anormalidades en el funcionamiento cerebral subyacentes a estos procesos y asociadas a la historial familiar de MDD deberían ser buenos candidatos para la identificación de endofenotipos de depresión...
Depression is one of the most prevalent mental disorder which generates great social, economic and human costs. Beyond, it presents a high comorbidity with other affective disorders and a high mortality rate (Paykel, Brugha & Fryeres, 2005). The familiar nature of the major depressive disorder (onwards, MDD) has been highlighted by several studies, and therefore, MDD has been conceptualized as a disorder originated by genetic components (Gershon et al., 1982; Sullivan, Neale & Kendler, 2000; Talati, Weissman & Hamilton, 2013) and its interaction with environmental factors (Bierut et al., 1999, Vázquez C. et al., 2010, Disner et al-. 2011). Therefore, individuals with a family history of depression (onwards, FH) are considered to manifest more likely depressive endophenotypes (Tatali et al., 2013).In general, MDD is considered as an affective disorder characterized by an altered emotional processing. Therefore, the abnormalities in the brain functioning underlying these processes associated to the FH status should represent reliable candidates for endophenotypes of depression...
