Emotional paralysis is a delayed and/or persistent response to an unusually threatening, catastrophic event. A traumatic event is necessary for the diagnosis of PTSD, but not sufficient for PTSD to occur, although most people experience symptoms to varying degrees after a traumatic event, and research suggests that only some people eventually become PTSD patients. PTSD manifests as a characteristic set of symptoms following a major traumatic event. The diagnosis is as follows: 1. Repeatedly re-experiencing traumatic experiences Patients re-experience traumatic events in various forms, with intrusive memories that do not go away, recurring traumatic scenarios in dreams, painful dreams, i.e., vivid experiences of reenactment of stressful events, recurring traumatic dreams or nightmares, repeatedly re-experiencing traumatic experiences; sometimes patients experience a dissociated state of consciousness, the duration of which can range from a few seconds to several days, called flashback (Sometimes patients experience a dissociated state of consciousness, which can last from a few seconds to a few days, called flash back.) This is called flashback, where the patient seems to be in the exact situation of the traumatic event and re-expresses the emotions associated with the event. When the patient faces or is exposed to events, situations or other cues related to or similar to the traumatic event, the patient usually experiences strong psychological pain and physiological reactions, such as the anniversary of the event, similar weather and various similar scenes, which may trigger the patient’s psychological and physiological reactions. 2. Persistent avoidance After the traumatic event, patients have persistent avoidance of trauma-related stimuli. The objects of avoidance include specific scenes and situations, related thoughts, feelings and topics, and patients are reluctant to mention the event and avoid related conversations. Loss of memory of important aspects of the traumatic event is also seen as a sign of avoidance. Avoidance is accompanied by “psychological numbness” or “emotional paralysis,” in which the person has a general feeling of mute indifference, a lack of interest in anything, a lack of interest in activities that used to be a passion, a feeling of detachment from the outside world, or even The patient feels distant and isolated from the outside world, or even out of touch with others; does not react to the surroundings; lacks pleasure; avoids recalling the activities of the previous traumatic situation; fears and avoidance of the trauma are also common. It seems to be indifferent to everything, and it is difficult to express and feel various delicate emotions. 3, persistent anxiety and increased level of alertness manifested as a spontaneous state of high alertness, such as difficulty sleeping, nor restful, easily frightened, unable to concentrate on things, and often have autonomic symptoms, such as panic, shortness of breath, etc..
