Understanding post-traumatic stress disorder
Sometimes after a terrifying event, a person can develop post-traumatic stress disorder, or PTSD. What are the risk factors, signs and symptoms of this condition? Scientists and clinicians are examining the scientific underpinnings of PTSD in an effort to better understand it and care for patients effectively. A panel of Harvard Medical School faculty members discusses how it is diagnosed and treated and share advice for family members and friends who have loved ones coping with the condition.
