Post-traumatic stress disorder

摘要

Post-traumatic stress disorder (PTSD) is an increasingly recognized and potentially preventable condition. Certain factors, especially the severity of the trauma, perceived lack of social support and peri-traumatic dissociation have been associated with its development. In recent years, a more robust evidence base regarding the management of individuals involved in traumatic events has emerged. Immediately after a traumatic event, simple practical, pragmatic support provided in a sympathetic manner by non-mental health professionals seems most likely to help. For individuals who develop persisting PTSD, trauma-focused cognitive behavioural therapy (TFCBT) may be beneficial within a few months of the trauma. For those who develop chronic PTSD, TFCBT and eye movement desensitization and reprocessing are best supported by the current evidence. Some anti-depressants appear to have a modest beneficial effect and are recommended as a second-line treatment. The current evidence base has allowed the development of guidelines that now require implementation. This has major implications in terms of planning and developing services that allow appropriately qualified and trained individuals to be available to cater adequately for the needs of survivors of traumatic events.
