Risk and protective factors for developing dementia following traumatic brain injury in adult men

Takeaway

  • Traumatic brain injury (TBI) significantly increases the risk of developing dementia.

  • Cognitive ability did not have a protective effect on the risk of dementia.

Why this matters

  • TBI and an increased risk of dementia have been previously linked.

  • Lower cognitive ability is associated with an increased risk of both TBI and dementia.
