Abstract:

Post traumatic stress disorder (PTSD) refers to a mental disorder in which an individual experiences a delayed, long-lasting and long-term meutal disorder after experiencing sudden, threatening or catastrophic life events. According to the diagnostic criteria of PTSD, the experience of traumatic events is the primary condition, that is to say, the external environment of individuals is crucial to the occurrence of PTSD. Special environments, such as plateaus, explosions, earthquakes, burns, and other disaster environments, including shipwrecks, mine disasters, and debris flows, can increase the risk of PTSD. In recent years, with the frequent occurrence of accidental traumatic events and natural disaster, the incidence of PTSD has increased year by year, and the disease duration is long while the cure rate is low, which has attracted great attention. PTSD can not only lead to the decline of individual quality of life and the damage of social and occupational functions, but also often share diseases with substance abuse, depression, anxiety, phobia and so on. In the absence of social support, PTSD can cause long-term negative impact on patients, families and society, and bring heavy economic burden. In order to explore the occurrence of PTSD in special environment and early warning of PTSD, this study reviewed the epidemiological characteristics of PTSD in special environment and the available intervention strategies.
