The South African Research Chairs Initiative (SARChI) Chair in Posttraumatic Stress Disorder (PTSD)

​

Chair overview

The South African Research Chairs Initiative (SARChI) is a flagship programme of the National Research Foundation (NRF) and is supported by the Department of Science and Technology and the NRF. The SARChI Chair in Posttraumatic Stress Disorder (PTSD) was awarded to Professor Soraya Seedat in 2007 and initiated in January 2008. PTSD is a severe, chronic and debilitating psychiatric disorder that occurs after exposure to extremely traumatic events and significantly impairs normal functioning and quality of life. Since its inception, the program has attracted a steady flow of both laboratory and clinically geared students and staff at honours, masters, doctoral and postdoctoral level.

The SARChI Chair in PTSD has a strong gene-brain-behaviour research focus (animal and human). Our human genetics research group aims to identify genetic factors that play a role in increasing or decreasing individual risk for PTSD by applying a three-pronged approach, which involves conducting gene expression and epigenetic analyses, as well as protein-protein interaction analyses. Projects in this regard include investigation of the effects of exercise on memory deficits brought on by stress, investigating the therapeutic effects of D-Cycloserine on fear extinction in an animal model for PTSD, and identification of ligands of proteins that are known to be involved in PTSD (e.g. wolframin). Projects within the clinical domain span a wide spectrum and include investigation of the psychopathological, neurocognitive, and imaging aspects of PTSD in the context of adolescent trauma, HIV, and fetal alcohol spectrum disorders, among others.
