Traumatic brain injury

Age at injury influences dementia risk after TBI

Nature Reviews Neurology volume 11, pages 128130 (2015) | Download Citation

Traumatic brain injury (TBI) is increasingly recognized as a risk factor for dementia. New data provide further support for this association and demonstrate the influence of age at injury and injury severity on dementia risk after TBI, revealing that even mild TBI increases dementia risk in those aged ≥65 years.
