Concussion is the mildest form of traumatic brain injury. It occurs as a transient inhibition of brain function following head trauma, characterized by a brief period of confusion post-injury, usually not exceeding half an hour. Patients may also experience retrograde amnesia, unable to recall the incident of injury. Neurological examinations and head CT scans typically show no significant abnormalities, and results from lumbar puncture and cerebrospinal fluid tests are normal. Most patients generally recover slowly after resting in bed for 1-2 weeks post-injury, without the need for special treatment. If symptoms such as headache or dizziness are prominent, some analgesics and sedatives or neurotrophic medications can be used for treatment, leading to gradual recovery. (Medication should be used under the guidance of a doctor.)
