Dr. Bremner’s research has used neuroimaging and neurobiology measures to study the neural correlates and neurobiology of posttraumatic stress disorder (PTSD) related to combat and childhood abuse, as well as the related area of depression. His more recent work is expanding to look at the relationship between brain, behavior, and physical health including studies of neurobiological mechanisms involved in the relationships between stress and depression and cardiovascular disease, as well as the effects of different treatments on the brain. His studies using magnetic resonance imaging (MRI) to show smaller hippocampal volume in PTSD are amongst the most highly cited in the field. He has authored over 400 scientific articles and book chapters, edited three books, wrote six books including “You Can’t Just Snap Out of It” and “Guiding Clients in Recovery from Psychological Trauma,” and developed and validated the Early Trauma Inventory (ETI) and the Clinician Administered States Scale (CADSS).
