Post-traumatic stress disorder

In the past few years, there has been a growing interest in the neurobiology of PTSD. A number of models have been proposed including possible structural changes. We have now seen the appearance in the literature of controlled and double-blind trials. Of interest are positive outcome studies associated with the use of drugs with serotonergic actions for a period of 8 weeks. Symptom relief provided by pharmacotherapy enables the patient to participate more thoroughly in individual, behavioral, or group therapy.
