Having a severe head injury, or repeated blows to your head over time, can lead to a condition called chronic traumatic encephalopathy (CTE). In some cases, CTE can result in dementia. 

This doesn’t mean you will definitely develop dementia if you’ve had head injuries. It just means your risk is higher. 

What you can do 

The best way to reduce your risk of CTE dementia is to protect your head and avoid injury. Here are some tips: 

  • Wear a helmet and safety gear when you play sport, skate, or ride a bike, scooter or motorbike. 
  • Wear a seatbelt when travelling in any vehicle. 
  • Obey road rules, including not driving after using drugs or alcohol. 
  • Minimise your risk of trips or falls inside and outside the home. 
  • Take extra care on slippery surfaces, stairs and ladders. 
  • Install and use handrails around stairs or in your bathroom. 
  • Secure rugs, carpets and loose electrical cords to reduce your chance of tripping. 
  • Use a walker or cane if you feel unsteady on your feet. 
  • Watch for pets or young children who might get under your feet while walking.
