High dose of stress hormone may cut post-traumatic stress disorder risk
October 28th, 2008 - 12:42 pm ICT by ANI Washington, October 28 (ANI): Ben-Gurion University of the Negev (BGU) researchers say that the risk of post-traumatic stress disorder (PTSD) can be reduced with the aid of a high dose of cortisone.
Writing about their findings in the journal Biological Psychiatry, the researchers revealed that in an animal model of PTSD, high doses of cortisol-related substance corticosterone was found to prevent negative consequences of stress exposure, including increased startle response and behavioural freezing when exposed to reminders of the stress.
Cortisol is secreted into the blood stream through the adrenal glands, which are active when the body responds to stress. It is known as “the stress hormone” because it is also secreted in higher levels during the body’’s “fight or flight” response to stress, and is responsible for several stress-related changes in the body.
“A single intervention with high-dose corticosterone immediately after exposure to a psychogenic stressor was highly effective in reducing the incidence of PTSD-like behaviors and improved the resilience to subsequent trauma-cue exposure in an innovative controlled prospective animal study,” said Dr. Hagit Cohen of the Anxiety and Stress Research Unit at the Faculty of Health Sciences, Ben-Gurion University of the Negev.
“Single high-dose corticosteroid treatment may thus be worthy of clinical investigation as a possible avenue for early pharmaco-therapeutic intervention in the acute phase, aimed at prevention of chronic stress-related disorders, such as PTSD.
“In this sense, it brings treatment of PTSD to a new era an era of secondary prevention, an era of the golden hours,” Cohen added. (ANI)
