You can sleep within 12 hours of a concussion injury. However, the first 24 hours after the trauma occurs is generally the most important observation period for the patient. That is, after the injury occurs, in the short term, the intracranial changes cannot be reflected by imaging, and the most important thing is to carry out observation. It is necessary to wake up the patient at intervals to observe the state of consciousness, limb activity, limb sensory movement, language function, etc. Through the observation of these symptoms, it reflects whether the patient’s intracranial de novo lesions occur. If the patient can be awakened during sleep, ask about headache symptoms, whether nausea, vomiting symptoms occur. If such conditions exist they need to be promptly reviewed again and further imaging is required. It is the detection of such late-onset problems and the detection of problems by imaging that provides the basis for the best treatment plan.
