2. impaired consciousness: head impact, concussion may suddenly lose consciousness, usually not for a long time, a few minutes to ten minutes to wake up.
3. Headache: some children will feel dizzy after hitting their head, but the duration is not very long, days or weeks are more common, a few people last longer.
4. Retrograde amnesia: that is, the patient is difficult to remember the recent events of the trauma, but can remember the more distant events.
