Who We Are We are a research group funded by the National Institutes of Health, Veterans Administration, and Department of Defense. We perform research on the brain and neurobiological correlates of posttraumatic stress disorder (PTSD), major depression, anxiety disorders and dissociation. Our mission is to understand how stress affects the brain and leads to mental disorders, and ways to translate this knowledge into new treatments. We are currently performing studies of brain imaging before and after treatment in veterans returning from Iraq with symptoms of posttraumatic stress disorder (PTSD) Including symptoms of intrusive memories, feeling cut off from others, trouble sleeping, increased startle, and avoidance of reminders of the war. We are also doing studies of non-veteran women with a history of childhood sexual abuse-related PTSD. Contact Stacy Ladd at (404) 712-2014 or firstname.lastname@example.org for more information.
