Study links traumatic brain injury to increased dementia risk

By Kathryn Doyle NEW YORK (Reuters Health) - Older military veterans who have suffered a serious head injury are more likely to be diagnosed with dementia than uninjured veterans, according to a new study. The report looked at traumatic brain injury (TBI), which includes concussions, skull fractures and bleeding inside the skull. “There have been a fair number of previous studies that have looked at the relationship between TBI and risk of dementia, and some have found an association while others haven't,” said lead author Deborah E. Barnes, from the University of California, San Francisco and the San Francisco Veterans Affairs Medical Center. She and her colleagues sought to clarify the relationship by taking into account other conditions, like depression and post-traumatic stress disorder (PTSD).
