”Emotional paralysis” is a phenomenon that exists in many patients with post-traumatic stress disorder (PTSD). Post traumatic stress disorder (PTSD), also known as delayed psychogenic reaction, is a delayed reaction caused by a stressful event or situation. To date, the pathogenesis of this disorder has not been elucidated. It is now well established that a traumatic event is a necessary but not sufficient condition for the onset of PTSD. Although most people experience symptoms to varying degrees after a traumatic event, only some of them eventually become PTSD patients. Many factors influence the development of PTSD, such as the presence of a family history and past history of psychiatric disorders, childhood trauma (e.g., sexual abuse, parental divorce before age 10), introversion and neurotic tendencies, other negative life events before and after the traumatic event, poor family situation, and the presence of a family member. These phenomena are still being studied in depth. It is believed that the clinical characteristics of PTSD are prolonged inability to recover from the trauma, partially confused sensory impressions and messy fragmented memories, repeated “flashbacks”, dissociation symptoms and somatization. This is because the memory process of the central nervous system for stress information is impaired, making the conditioned fear response difficult to suppress or overly suppressed.
