Brain injuries sometimes don’t become apparent for years.

Traumatic brain injuries increase the risk of dementia even decades later.

That’s according to a new long-term study conducted in Sweden.

People who suffered a brain injury were four to six times more likely to develop dementia within the first year.

While that risk declined over time it was still significant more than 30 years after the injury.

Patients with more severe or multiple brain injuries had the highest risk of developing dementia.
