Concussion occurs after a fall or an impact to the head.


Concussion occurs after a fall or an impact to the head. Headaches occur, possibly accompanied by loss of consciousness, gaps in memory and nausea. The symptoms can linger for a few days, during which it is important to rest the body.


Causes and treatment


  • Severe impact to the head (e.g. owing to an accident, a fall, while doing sport, etc.)

Further treatment by your doctor / in hospital

Possible tests
  • Detailed exam and cognitive tests (e.g. finger-counting and other special tests)
  • CT scan (computed tomography)
  • MRI (magnetic resonance imaging)
Possible therapies

As a rule, concussion clears up by itself without the need for any special treatment. Extra care is required, however, if there are other, more dangerous symptoms (see When to see a doctor).

  • 24-hour observation in hospital
  • Painkillers

What can I do myself?

  • Immediately stop all activity (e.g. sport)
  • Treat wounds, if any
  • Get plenty of rest during the healing phase
  • Only take up sport again when all the symptoms have gone
  • Protect the head (e.g. by wearing a helmet)

When to see a doctor?

  • Very severe headaches, which don't go away and may even become worse
  • If consciousness is affected (e.g. the injured person no longer knows where they are or speaks incoherently)
  • If the injured person suddenly becomes listless or loses consciousness (even if they wake up again)
  • Vomiting
  • Double vision
  • Persons who take blood-thinning medication (anticoagulants)
  • Other serious injuries
  • If symptoms don't improve after a few days
