Neuroendocrine studies examining the hypothalamic-pituitary-adrenal (HPA) axis under baseline conditions and in response to neuroendocrine challenges have supported the hypothesis of altered HPA functioning in posttraumatic stress disorder (PTSD). However, to date, there is much debate concerning the nature of HPA changes in PTSD. Furthermore, in studies showing parallel findings in PTSD and major depressive disorder there is controversy regarding whether the HPA alterations suggest a specific pathophysiology of PTSD, or, rather, reflect comorbid major depressive disorder. This review summarizes findings of HPA axis dysfunction in both PTSD and major depressive disorder, and shows distinct patterns of HPA changes, which are probably due to different mechanisms of action for cortisol and its regulatory factors.

In November of 2015, Sean suffered a moderate traumatic brain injury from a fall; his life since has been solely devoted to the topic of this blog - TBI and other forms of acquired brain injury. With his passions and life as he imagined it to be on an indeterminate hold during his rehabilitation and recovery, he began this blog and a TBI health advocacy group. Through uniform rules of professional responsibility and ethics, he hopes the health advocate profession may be an affordable adjunct to the team needed by every brain injured person and those caring for them. He hopes that this blog will continue educating and supporting survivors of brain injury, their caregivers, and anyone interested in this devastating medical sojourn, alongside the discovery of a new self and a meaningful life outside the treatment environment. Sean is active in supporting mental health and suicide crisis support, various manifestations of trauma in children and adults, and is a Doctor of Law with a focus on health and science law. He is also an athlete, poet, writer, and nature enthusiast.
