Many of our programs are funded by national agencies such as the National Institute of Mental Health, Department of Defense, and the Department of Veterans Affairs. Our programs are designed to gain a better scientific understanding of the biology of stress reactions, and how to treat them better. Through this funded research we have been able to gain a better understanding of posttraumatic stress disorder (PTSD) and stress responses.

Stress Response
When confronted with extreme stress, the body initiates many chemical reactions to facilitate a quick escape from stress. The amygdala is the brain region that alerts the body to danger and activates hormonal systems. Activation of the hormones noradrenaline and adrenaline results in accelerated breathing, pulse, and heart rate, and increased release of energy to muscles and other organs, which literally helps people run faster from stress or mobilize a response that requires coping with the stressor head-on. Once the immediate danger has passed, other hormones, particularly the hormone cortisol, help terminate stress-activated reactions. Usually, the more stress there is, the more cortisol is needed to contain the stress response. Our work has demonstrated that trauma survivors with PTSD have higher levels of noradrenaline1,2 and lower levels of the hormone cortisol.3,4,5

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device, biotechnology companies, and other outside entities to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their outside financial relationships.
