Interplay between Neuroimmunoendocrine Systems during Post-Traumatic Stress Disorder: A Minireview (original) (raw)

Neuroimmunomodulation, 2010

Abstract

Early life stress has been suggested to mediate vulnerability to affective disorders. Traumatic events experienced in childhood such as sexual abuse and/or physical neglect may lead to psychiatric diseases in adult life, including post-traumatic stress disorder (PTSD). Previous studies have focused on adult traumatic events and very little is known regarding the long-term physiological effects of early life stress. Here, we review the complex interplay between most important cognitive, neuroendocrine and immunological changes reported in PTSD, focusing on long-term implications of childhood maltreatment. PTSD has been associated with significant biological changes related to impaired cognitive functions, attenuated hypothalamic-pituitary-adrenal (HPA) axis function (hypocortisolism) and activation of innate immune responses (low-grade inflammation).
