The severity of brain injury can be determined by clinical symptoms, imaging tests and other methods.
1. Clinical symptoms: If there is a serious brain injury, there may be consciousness disorder, lethargy, coma, epileptic seizure, and even mental symptoms such as mood and personality changes, and in severe cases, pupil dilatation and so on may occur.
2. Imaging examination: it mainly includes cranial CT and cranial MRI, which can clarify the location, severity and nature of the brain injury.
3. Other methods: the intracranial pressure of the patient can be monitored, if there is a significant increase in intracranial pressure, it may suggest that the brain injury is more serious, and the cranial CT should be reviewed if necessary.
It should be noted that the degree of brain damage should be combined with the above examination by a professional doctor to make a comprehensive judgment, so if you suspect that there is a brain injury, you should consult a doctor in a timely manner, and actively diagnose and treat under the guidance of the doctor.
