A recent publication in Neurology, the official journal of the American Academy of Neurology, found that traumatic brain injury and the risk of dementia in older military veterans. “Traumatic brain injury and risk of dementia in older veterans,” Deborah E. Barnes, PhD, MPH, Allison Kaup, PhD, Katharine A. Kirby, MA, Amy L. Byers, PhD, MPH, Ramon Diaz-Arrastia, MD, PhD and Kristine Yaffe, MD.

The researchers from the University of California, San Francisco, San Francisco Veterans Affairs Medical Center and the Uniform Services University of the Health Sciences and Center for Neuroscience and Regenerative Medicine in Bethesda, Maryland, examined the association between traumatic brain injury and risk of dementia in veterans.

The researchers performed a “retrospective cohort study” of 188,000 U.S. veterans age 55 years or older who had at least one in-patient or out-patient visit during the baseline (2000-2003) and follow-up (2003-2012) and did not have a dementia diagnosis at baseline.

According to the abstract, which can be found here, traumatic brain injury in older veterans was associated with a 60 percent increase in the risk of developing dementia over nine years after accounting for continuous and potential confounders. “Our results suggest that TBI in older veterans may predispose toward development of symptomatic dementia and raise concern about the potential long-term consequences of traumatic brain injury in younger veterans and civilians."
