November 2021: Using Neuroimaging to Classify Victims of Trauma

Dr. Jennifer Stevens (Assistant Professor of Psychiatry and Behavioral Sciences, Emory University) discusses a technique to classify trauma victims into discrete biotypes in the immediate aftermath of trauma, with the hope of providing insight into the groups that could guide treatment, and American Journal of Psychiatry Editor-in-Chief Dr. Ned Kalin puts the November, 2021 issue of AJP into context.
