Dementia Risk Rises with Traumatic Brain Injury

A review of data on 188,774 veterans (ages 55 and up) found that 1,229 had been diagnosed with a traumatic brain injury (TBI). During the study’s nine-year follow-up period, 16% of veterans with a TBI developed dementia compared with only 10% of veterans without a TBI.
