title: Post-traumatic stress disorder: a review of recent findings.
abstract: This article provides an update on recent findings in post-traumatic stress disorder (PTSD) with reference to pertinent epidemiologic, etiologic, diagnostic, and treatment advances in the past year. New studies serve to confirm high prevalence rates in the general population (7% to 12%), and high rates of secondary mood, anxiety, and substance use disorders. Recent substantive evidence has highlighted 1) the unique pattern of biological alteration in PTSD that distinguishes it from the normative stress response, and 2) the role of constitutional risk factors and trauma-related factors in determining disease expression after trauma exposure. The emergence of consistent data suggesting that medications (selective serotonin reuptake inhibitors) and psychotherapies (cognitive-behavior therapy) are effective in reducing core symptoms and improving quality of life, has reinforced optimism and more widespread use of these interventions in patients with PTSD.
