Depression and generalized anxiety disorder, not posttraumatic stress disorder (PTSD), were the most common new psychiatric disorders in the year following traumatic injuries to 817 patients. Bryant et al. (CME, p. 312) also note that PTSD typically occurred in the presence of another psychiatric disorder. Overall, 23% of the patients developed psychiatric disorders, and patients with mild traumatic brain injury were twice as likely as other patients with traumatic injuries to develop PTSD, panic disorder, agoraphobia, or social phobia. Mild traumatic brain injury was associated with functional impairment only in the presence of a psychiatric disorder.
