There is a reward for a high score of 500 on the forehead, and there is something wrong with the brain.

Judging from what you described, there should be no brain damage.

The human brain has a damping mechanism, and the intracranial brain tissue is floating in a liquid environment, which has a buffering effect when it is impacted by external forces. Unless it is a violent collision, the general collision will not cause damage to brain tissue.

If there is brain tissue damage, it will show up in a short time: headache, vomiting, decreased vision, dizziness and so on. It's been a while since your head collided with someone else. If there was a problem, you would have had symptoms.

Judging from what you said, the body is definitely not damaged and will not affect the intelligence and thinking ability.

If it was in normal times, it might have passed.

However, it happens that you are under great pressure to study recently and feel anxious inside, and that scene is always played back in front of you.

In fact, hitting your head is just an inducement, and the key is your anxiety about learning pressure.

Even if there is no collision, it may be related to other things, such as something that makes you feel bad or something else.

Now that we know the root of the problem, there is a way to solve it:

Adjust your mood, combine work and rest, adjust your study, and go into battle lightly. You can also carry out some extracurricular activities, physical exercise and group activities as appropriate.

As long as the problem of study is solved, you will naturally stop thinking about your head.

If this situation still cannot be solved, it will even increase.

I suggest you seek the help of a psychologist and ask them to help you solve your inner anxiety.
