Dr. Lv Zhiqin
The main symptoms of traumatic brain injury include the following aspects:
1. Disorders of consciousness: Mild cases may present with drowsiness or somnolence, while severe cases may involve light coma, deep coma, or even prolonged unconsciousness leading to a vegetative state.
2. Headache and vomiting: These may be caused by local trauma to the scalp or skull, intracranial hemorrhage, changes in intracranial pressure, and other factors. Headache can range from mild to severe, and vomiting is often caused by intracranial hemorrhage stimulating the vagus nerve or vestibular system.
3. Eye symptoms: Unequal pupil size, extreme constriction, or loss of light reflex may indicate damage to the midbrain or pons. Abnormal eye position and movement, such as conjugate gaze deviation or restricted movement, may also occur.
4. Limb movement disorders: Symptoms such as monoplegia, hemiplegia, or paraplegia may appear, indicating damage to the brain's motor nerves.
5. Epileptic seizures: Some patients with traumatic brain injury may experience seizures, manifested as foaming at the mouth, convulsions of the limbs, and other symptoms.
6. Other symptoms: These may include memory loss, aphasia, blindness, dizziness, hemiplegia, weakness, and sensory loss.
If these symptoms appear, timely medical attention is necessary.
