Post-traumatic stress disorder (PTSD) is the most serious physical and psychological disorder after a disaster. It was originally used to describe the outcomes of all types of traumatic war experiences, also known as “war fatigue”. It was later found that it can occur after an individual experiences a life-threatening event (triggers can range from natural disasters and accidents to criminal violence, abuse, and war). This stress can be experienced either directly, such as direct injury, or indirectly, such as witnessing the death or injury of another person. People have a range of physical and psychological reactions after suffering a natural or man-made disaster, experiencing firsthand injuries, losing a loved one or friend, or witnessing the death or injury of another person. These reactions include panic, apprehension, depression, insomnia, and frequent nightmares. Some people will be irritable and irritable, while others will be distracted and have difficulty concentrating. People also tend to involuntarily have vivid memories of catastrophic situations, which lead to physical and psychological emergency reactions (e.g., sweating, rapid heartbeat, extreme panic). At the same time, people with PTSD try to avoid contact with and reference to the disaster they experienced, they avoid revisiting the same places, they are usually in a constant depressed mood, and they lose interest in matters that previously interested them. They may also isolate themselves and avoid interacting with others. They may appear dull and unresponsive to people and events. All of the above reactions are normal human stress functions. Many people will experience a reduction in symptoms. Although many of the symptoms will persist for some time, they are not severe enough to interfere with normal work and life. Therefore, according to the diagnostic criteria, only when enough symptoms persist 1 month after the disaster and the severity of these symptoms has interfered with normal life, can the patient be diagnosed with “PTSD “. PTSD usually includes both pharmacological and psychological treatments. Antidepressant medications can relieve the symptoms of PTSD; interviewing with a therapist can also help you get through your PTSD.
