Project Description Narrative:


All too often, people who experience a traumatic event go on to develop post-traumatic stress disorder (PTSD). A long-lasting form of the disorder, when symptoms do not go away or later re-emerge, occurs in one in four traumatic injury survivors. PTSD disrupts daily life, interfering with the ability to perform typical daily tasks, making it hard to work, and complicating relationships with family and friends. These challenges can lead to other problems, including depression, drug or alcohol abuse, and other physical or mental health conditions. In fact, PTSD is the anxiety disorder with the highest cost burden to society.

PTSD is associated with changes in brain function and structure. While there has been progress in understanding who is at risk for PTSD following traumatic injury, there remains much to learn regarding PTSD development in order to provide better and more timely intervention and treatment options.

Through this award, a collaborative research team aims to apply novel strategies, including looking at marks present on DNA in the blood, to understand risk for chronic PTSD and recognize patterns that connect with changes in brain function after traumatic injury in order to develop patient-centered screening and intervention approaches.
