There is transient memory loss after a brain fall, which is usually not serious. After head trauma, the patient needs to arrange for a cranial CT examination to rule out cranial hemorrhage or cerebral contusion, and if there is no abnormality in the cranial CT examination, the above situation is considered to be a concussion. Many concussion patients may have transient memory loss after the injury, but it is often no more than 30 minutes, and after a brief recovery, the patient’s memory can usually return to normal. Patients with concussion have no abnormality in cranial CT, and the results of cerebrospinal fluid examination are normal, which may be accompanied by headache, dizziness, nausea, vomiting and other manifestations, and the symptoms will be relieved after giving targeted treatments, meanwhile, pay attention to rest. If there is any discomfort, it is recommended to go to the hospital in time, do not be careless, so as not to delay the treatment.
