It refers to the abnormal mental reaction to severe stress factors (such as trauma). Also known as delayed psychogenic response, it refers to a mental disorder that is delayed and lasts for a long time due to unusual threatening or catastrophic psychological trauma.

PTSD mainly occurs in men, mainly soldiers who have experienced war, so it is called "shell shock" and "combat fatigue".

Current research shows that everyone, including children, has the possibility of PTSD, and the possibility of women is twice that of men. Perhaps this is the performance of women being sexually or physically attacked.

To sum up, there are three symptoms:

1, re-experience: that is, an individual will experience an invasive reappearance of a traumatic situation, and the content of the reappearance is very clear and specific. In particular, anything in life that may be related to trauma may lead individuals to relive traumatic situations. This kind of experience will bring great pain to individuals, and may further deteriorate, resulting in some PTSD-related diseases (such as anxiety, fear, self-blame, disappointment, complaints, etc. );

2. Avoidance reaction: Out of the pain of re-experiencing, the individual will actively avoid some things and things that may lead to traumatic experiences. Moreover, this avoidance reaction may be unconscious, that is, it is manifested as "forgetting". On the one hand, this avoidance reaction is a protective mechanism for individuals; On the other hand, it will delay the recovery of PTSD-related disorders in individuals;

3, high vigilance: it is a strong reaction to many small details. Further manifestations are insomnia and inattention. "

The performance of this disease is very prominent. When a soldier returns to normal society after a long battle, bloodshed and death on the battlefield, there will be great trouble. Rambo highlighted this symptom in the original film "First Blood". In the novel Wolves, which I think is excellent, the ghoul Xingtian suffers from this terrible disease (as does the butcher). Personally, ghouls, as a civilian, entered the extremely cruel battlefield almost without combat training, and killed nearly 100 people in World War I (or killed with a knife at close range).

The biggest feature of the sequela of war trauma is that you don't trust others, but you will find a sense of security in the military camp, which is why when soldiers ask their old superiors about the sequela of war trauma, the first sentence is: You really shouldn't have left the army at the beginning.

War will be inevitable. In the face of those soldiers who come back from the front line, we should tolerate and care for them and make them feel safe. The country should provide these soldiers with a good way out and a good future. Don't let them fight for the country and the people and come back chilling.
