- Head injury is not associated with dementia risk at all
- Everyone who suffers a serious head injury will develop dementia
The correct answer is 1. Serious head injury, especially with loss of consciousness, has been associated with an increased risk of developing dementia. But it doesn’t mean you will definitely get dementia, just that you have a higher risk. Protect your head from injury as much as possible.
