Concussion (March 28, 2020)

You can get a concussion if you hit your head so the brain moves. You can then lose consciousness or lose your memory for a short while. It is important that you do not strain your brain too much after a concussion so that it can recover.

It is common for children to hit their heads and for the most part there is no danger. But often it is a concussion if the child loses consciousness.


You may lose consciousness in a concussion. These are some other common symptoms that sometimes only come after several hours:

  • headache
  • dizziness
  • nausea
  • vomiting
  • memory loss
  • confusion
  • unnatural fatigue.

When and where should I seek care?

It can be difficult to judge for yourself if you need to seek care. If you suspect that you or a child has had a concussion, call 112 to get medical advice. Then you can get help to assess symptoms or help with where you can seek care.

If it’s in a hurry

Call 112 immediately if any of the following are true:

  • Someone has hit his head and fainted for more than a minute.
  • Anyone who has hit their head has cramps.
  • It takes a long time for the person to recover, and the fainting is followed by dizziness, confusion or sleepiness.

Investigations and investigations

You will be examined by a doctor if you have had a concussion. You may also have blood tests to show if you have had a brain injury.

Sometimes you are examined with computed tomography so that the doctor can see if you have any serious injuries. Bleeding can occur, the brain can swell and you can get damage to the skull if you get a severe blow to the head.

You have the right to understand

In order for you to be able to participate in your care and make decisions, it is important that you understand the information you receive from the healthcare staff. Ask questions if you don’t understand. You can also ask for information printed so that you can read it peacefully. If you do not speak English or have a hearing impairment, you may have the right to get help from an interpreter.

What can I do for myself?

There is no special treatment after a concussion except to rest so that the brain can recover. You should not exercise or drink alcohol until you feel good again. Avoid things that require a lot of concentration. This includes, for example, watching TV, playing computer games and other things that can cause headaches and nausea.
