Concussion is a common cranio-cerebral injury in daily life, mainly manifested as coma immediately after head injury, which will naturally wake up within 30 minutes with headache, dizziness and fatigue. At the same time, the patient cannot recall the time and place where the injury occurred or the situation shortly before the injury, but remembers more clearly the longer before the injury, which doctors call near-event amnesia. With proper treatment of concussion, various symptoms can disappear in a few days or weeks. However, in some people, not only do headaches and dizziness not improve after a concussion, but they also experience anxiety and depression such as feeling serious problems with their brain and body, unstable sleep, nausea or stomach discomfort, fear of going to open places or going out on the street, and feeling bitter and uninterested in things. What is this all about? We know that concussion is the mildest type of traumatic brain injury, and there is nothing complicated about its injury. Experimental results in animal models of concussion have shown that the biochemical changes in damaged brain tissue and cerebrospinal fluid can be completely restored to normal under light and electron microscopic observation. A questionnaire survey was conducted on 122 patients 1 month after concussion injury, and it was found that depression and anxiety were more likely to occur after concussion than normal, with paranoia and psychotic manifestations as the main symptoms in men, and depression and anxiety symptoms more prominent in women. Meanwhile, the psychological stress capacity of people with higher education level after concussion is lower than that of those with lower education level, probably because most of the former are engaged in complex mental labor and competitive pressure, and they are depressed and afraid of losing their original social status due to the fear of not recovering from injury or illness as early as possible, resulting in serious psychological burden. However, because they have the opportunity and ability to master more medical knowledge about concussion, they have less anxiety symptoms. All these indicate that the delayed concussion is related to psychological factors, which is the result of the interaction between pathological and psychological factors of traumatic brain injury. For a long time, people have superficial knowledge about concussions and inappropriately exaggerate the severity of concussion injuries, thinking that all traumatic brain injuries must have sequelae. They can also cite many examples to illustrate this problem, such as the naval hero Mai Xiande and the Wuhan police officer who fought bravely with robbers resulting in a gunshot wound to the head, all of whom left after-effects. It is not understood that this is a heavy brain injury, where the brain parenchyma is damaged, affecting the function of this part of the brain and thus producing sequelae. Therefore, concussion patients and their families should realize that concussions do not have sequelae to avoid aggravating the psychological burden and bringing unnecessary troubles. During the recovery period of concussion, you can take part in some recreational activities and do physical exercise appropriately, which can not only enhance physical fitness, but also distract the attention from the sequelae of concussion and accelerate the recovery of the disease. When the concussion does not heal and has a serious psychological disorder, it is necessary to promptly ask a psychologist to give psychological treatment.
