Serious head injuries nearly double your risk of dementia

Serious head injuries nearly double a person’s risk of developing dementia. That’s the message from an analysis of over 40,000 people who sustained some kind of head injury between 1986 and 2014.

Half the people in the study had moderate-to-severe head injuries, which cause lesions in the brain and require a person to stay in hospital for three days or more. The other half had milder head injuries with no lesions, and were able to go home within a day.
