Primary care treatment of post-traumatic stress disorder.

Post-traumatic stress disorder, a psychiatric disorder, arises following exposure to perceived life-threatening trauma. Its symptoms can mimic those of anxiety or depressive disorders, but with appropriate screening, the diagnosis is easily made. Current treatment strategies combine patient education; pharmacologic interventions, such as selective serotonin reuptake inhibitors, trazodone and clonidine; and psychotherapy. As soon after the trauma as possible, techniques to prevent the development of post-traumatic stress disorder, such as structured stress debriefings, should be administered. A high index of suspicion for post-traumatic stress disorder is needed in patients with a history of significant trauma.
