Study finds increased risk of dementia after hospitalization for major TBI

People who have been hospitalized for a major traumatic brain injury (TBI) may have a higher risk of developing dementia when compared to people who do not have a TBI, according to a new study published in the May 11, 2022, online issue of Neurology, the medical journal of the American Academy of Neurology. Major TBI was defined as having bleeding in the brain and a hospital stay of three or more days. Researchers did not find an increased risk for people who had minor TBI, which was defined as a concussion with no more than a one-day hospital stay.
