[Peculiarities of clinical presentations of posttraumatic stress disorder and its treatment in different types of traumatic exposures].

The authors study the exposure to different extreme events on examples of two types of stress--combat stress and the liquidation of Chernobyl accident. Thirty combatants and 33 liquidators have been examined and treated. Peculiarities of the initial study of stress reactions and posttraumatic stress disorder (PTSD) due to its main diagnostic criteria have been analyzed in each group of subjects. The authors conclude that similar pathological states, including all symptoms of PTSD, develop in response to different stressful exposures. At the same time, there are significant phenomenological differences in syndromes that are determined by the character of stressful (traumatic) event. Issues of complex treatment of patients using psychotherapy and pharmacotherapy as well as approaches to rehabilitation and social support are discussed in details.
