Symptoms of Concussion
Concussion is generally characterized by a clear history of head trauma, with transient consciousness disorders following the injury, usually lasting less than 30 minutes. It is often seen in falls from heights, car accidents, or injuries caused by accidental hits from others. After regaining consciousness, patients with concussions may experience headaches, dizziness, nausea, and vomiting. Some patients may have difficulty recalling the incident clearly, which is clinically referred to as retrograde amnesia. When these symptoms appear, a concussion is likely, and the patient should be immediately hospitalized for treatment; a head CT or MRI should be performed to help rule out the possibility of other intracranial organic diseases.
