Rostral Middle Frontal Gyrus Thickness Is Associated With Perceived Stress And Depressive Symptomatology, Lindsay J. Michalski
Rostral Middle Frontal Gyrus Thickness Is Associated With Perceived Stress And Depressive Symptomatology, Lindsay J. Michalski
Arts & Sciences Electronic Theses and Dissertations
Elevated stress perception and depression commonly co-occur and have shared genetic and environmental influences, suggesting they may rest upon a common underlying neurobiology. The rostral middle frontal gyrus (RMFG), part of the dorsolateral prefrontal cortex, is critical for executive function, including emotion regulation and working memory. Variability in RMFG cortical thickness has been associated with both depression and stress-related phenotypes, although the directionality of these associations has been inconsistent thus far. The current study examined healthy participants (n=879) who completed the ongoing family-based Human Connectome Project were included in analyses. RMFG cortical thickness was computed from structural magnetic resonance imaging …
Suicide Attempts From Adolescence Into Young Adulthood: A System Dynamics Perspective For Intervention And Prevention, Saras Yu Chung
Suicide Attempts From Adolescence Into Young Adulthood: A System Dynamics Perspective For Intervention And Prevention, Saras Yu Chung
Arts & Sciences Electronic Theses and Dissertations
Though the reduction of suicide-related deaths has been a national priority for over a decade (U.S. Department of Health and Human Services, 2001) and over $22 million per year (National Institutes of Health, 2015) have been invested to prevent suicide, rates of suicide have not declined (CDC, 2012). In fact, for some groups of adolescents, these rates seem to be on the ride (Wasserman, Cheng, & Jiang, 2005). The ineffectiveness in reducing deaths by suicide despite increased funding and coordinated efforts suggests the need for a new perspective on examining why and how adolescents begin to desire and attempt suicide …
