Traumatic experiences often come with biological consequences in the human organism. Patients suffering from Posttraumatic Stress Disorder (PTSD) for example have a higher riks for many diseases, in particular cardiovascular disease. In our research focus "Traumatic Stress and Health", we aim to understand the biological pathways between trauma and psychological response to trauma and pathophysiological changes in the organism's periphery that might explain higher rates of morbidity and mortality in PTSD.
