Abstract
Stressful and traumatic events are recognised as important risk factors for a number of psychiatric disorders, however it has
been difficult to identify the mechanism of how stress leads to psychopathology (McEwen and Stellar, 1993). Previous work has
demonstrated that stressful life events affect brain structure, notably observed as reduction in grey matter volume (GMV) within
regions such as the hippocampus, anterior cingulate cortex (ACC) and orbitofrontal cortex. It is theorised that an over-exposure
to stress hormones such as glucocorticoids results in dendritic atrophy, reduced neurogenesis, and neuronal death, resulting in
an observable reduction in GMV (Radley and Morrison, 2005).
