The diagnosis of mild concussion is not based on examination, but on the combination of clinical symptoms after the relevant examinations have been completed and other diseases have been ruled out. In clinical practice, the symptoms of mild concussion are very similar to those of cerebral contusion, subdural hematoma and epidural hematoma. It is difficult to judge the condition solely from the clinical symptoms. Because concussion patients do not have organic damage, the examination will not have obvious lesions found, so generally do not rely on the examination to confirm the diagnosis. However, it is also important to improve the relevant examination, after excluding other diseases, and then combined with the patient’s clinical manifestations, by the doctor’s comprehensive judgment can be finally diagnosed as concussion. It is recommended that patients with suspected concussions seek medical attention in a timely manner and be actively diagnosed and treated under the guidance of a doctor.
