Traumatic Brain Injury in Older Adults Associated with Dementia Risk.
After reviewing the available data on nearly 52,000 individuals in California who had suffered a traumatic brain injury (TBI), researchers believe the data indicate that such persons may have a 1.45 times greater risk for a dementia diagnosis later in life. In particular, the risk was greatest among older individuals (ages 65 and up) who suffered a mild TBI, and those between ages 55 and 64 who suffered a moderate-to-severe TBI. The authors of the study add that the brains of younger adults may be more resilient to the effects of a traumatic brain injury.
