1.Headache
The degree of headache is more severe, ineffective with general painkillers, often accompanied by frequent nausea and vomiting.
2.Paralysis
The movement of the limb is normal at the time of injury, but gradually the gait becomes unstable, or one upper limb is weak and difficult to lift.
3.Drowsiness
If the originally awake person becomes deeply asleep or difficult to wake up, do not think it is asleep, but should be alert to the deepening of coma.
4.Twitching
Twitching of limbs is called paralytic seizure, which is an idiosyncratic manifestation of stimulated brain cell discharge seizure.
5. Pupil dilatation
When normal, the pupils are equally large and round on both sides, and the pupils narrow after light exposure. When abnormal, one pupil is larger than the other, and the light response is dull.
6.Bedwetting
Bedwetting suggests pressure on the urinary center of the brain, and bedwetting in adults may be the first sign of intracranial hematoma.
7.Slow heartbeat
Normal adult heartbeat slows down to less than 40-50 beats per minute, accompanied by elevated blood pressure and slowed breathing, suggesting that intracranial hematoma or cerebral edema has occurred.
8. Restlessness
Extreme restlessness with profuse sweating indicates that the intracranial pressure has increased to a degree that is difficult to compensate.
9.Mental abnormality
Confusion and lack of concentration, unable to do things as usual.
10.Vertigo
Patients with early traumatic brain injury all have complaints of dizziness and are often accompanied by nausea and vomiting. If the vertigo becomes unbearable, one should be alert to the possibility of intracranial hematoma.
When the above-mentioned critical signs occur, emergency measures should be taken urgently.
