For all the attention focused on posttraumatic stress disorder (Post-traumatic Stress DisorderPost-traumatic Stress Disorder (PTSD)A complex psychiatric syndrome that develops in response to trauma exposure. Individuals with PTSD experience intrusive recollections or reexperiencing of the traumatic event, avoidance of trauma reminders, emotional numbing, and hyperarousal. In addition, PTSD is associated with high rates of concomitant physical and mental health problems, increased health care use, and impairment in social and occupational functioning. Almost 7% of the general population and up to 30% of veterans meet lifetime criteria for PTSD. Indeed, PTSD is one of the most common psychiatric disorders, representing a significant and costly public health concern.) in recent years, doctors have never had a clear-cut way to be certain a patient has it.

"There have been questions that this is a made-up disorder and isn't a true brain disease, but it is." Just as importantly, he says, the magnetic-imaging biomarker shows changes over time in a brain's electrical activity, allowing mental-health workers to chart the effectiveness of various therapies. "It will be a tremendous tool in monitoring treatment," he says, "because these abnormal communication patterns will be normalized as the treatment works." ...
