Does a mild concussion require hospitalization?

A concussion is a temporary brain dysfunction that occurs immediately after an external blow to the head. Pathological changes do not change significantly, and the mechanism is still controversial at this stage. Clinical manifestations are transient coma, retrograde amnesia, headache, nausea, vomiting, etc. There are no positive signs in neurological examination, and the disturbance of consciousness is normally relieved within 30 minutes. This is the lightest kind of brain injury. After treatment, most can be completely cured. A brain CT scan shows no obvious abnormalities in the brain and skull. A mild concussion usually does not require hospitalization. It can be observed in an outpatient clinic for a period of time to observe the patient's vital signs. In normal patients, symptoms improve after rest and oral medication to improve brain cell metabolism. Close observation is required for a period of time, and if the patient shows signs of increased headache, confusion, or paralysis of the limbs, it is necessary to see a doctor promptly to prevent delayed subdural hematoma.
