A new study published this week in Neurology found that veterans who have experienced a traumatic brain injury (TBI) are 60 percent more likely to later develop dementia than veterans who have not.
The study involved more than 180,000 veterans with an average age of 68 at the start of the study. All were free of dementia at the start of the study and had at least one visit to a Department of Veterans Affairs health care facility when the study began and again an average of seven years later. The results were found after adjusting for other factors that could affect the risk of dementia, such as diabetes, high blood pressure, depression, and alcohol abuse.
The study was supported by the U.S. Department of Defense/NCIRE and the National Institutes of Health.
