A Canadian/U.S. research team has reported a novel approach to stimulating recovery from chronic stress disorders. Details of the therapeutic model, which exploits the natural dynamics of the body's 'fight or flight' system, are published 23 January in the open-access journal PLoS Computational Biology. In contrast to conventional time-invariant therapy, the researchers propose a well-directed therapeutic push delivered according to an optimal treatment schedule.
The hypothalamic, pituitary, adrenal (HPA) axis constitutes one of the body's major control systems, serving to maintain body homeostasis with hormone feedback regulatory loops. If the HPA axis is driven very far from its natural homeostatic rest point, it may be unable to fully recover the healthy physiologic state. Under such conditions, the HPA axis dysfunction may become chronic. HPA axis dysfunction has been characterised in disorders including Chronic Fatigue Syndrome (CFS), depression, post- traumatic stress disorder and Alzheimer disease.
The research team, consisting of Drs. Amos Ben-Zvi, Suzanne D. Vernon, and Gordon Broderick, used a relatively simple mathematical description of the HPA axis to show how the complex dynamical behaviour of this system could accommodate multiple stable resting states; some corresponding to chronic loss of function characterised by low cortisol, a hormone that modulates immune function. A robust treatment strategy was designed to take advantage of the body's existing homeostatic mechanism, using a short-duration intervention to assist the HPA axis in re-asserting homeostasis about a healthy equilibrium. Akin to pulling back a slingshot, temporarily reducing the bioavailability of cortisol pharmacologically causes the HPA axis to overcompensate and launch itself back into a correct regulatory regime

I read one of the leading drugs to do this is mifepristone, in high doses for a short time and this blocks the cortisol receptor, up regulating acth and other hpa hormones.. helping to normalize the stress system. Mifipristone is an abortion pill right now, and is really expensive.. I know I'm going out on a limp here but there was studies done and no negative side effects and people with depression and PTSD both showed improvements..
