Mild concussions usually resolve themselves within 1 week. A mild concussion is usually characterized by dizziness, headache, nausea, and retrograde amnesia. After resting, the patient will recover gradually within 1 week and will have a better recovery without neurological sequelae. If the condition worsens in the early stage of the disease, it is considered to be related to secondary lesions, such as cerebral contusion, intracranial hemorrhage, etc., and it is necessary to improve the relevant auxiliary examinations and carry out symptomatic treatment under the guidance of the doctor. Generally speaking, concussion is a relatively mild clinical disease, and will gradually return to normal after a period of rest.
