Traumatic brain injury in late life tied to elevated dementia risk

Traumatic brain injury (TBI) in late life is associated with a significant increase in the risk for new-onset dementia. The risk is especially elevated (by as much as 69%) within the first 5 years following the injury, according to newly published study findings. Though TBI, which results from direct impact or indirect force to the head, has long been recognized as a midlife risk factor for dementia, the risk that TBI poses in adults aged 65 years or older has been unclear.
