Medical and Psychiatric Risk Factors for Dementia in Veterans with and without Traumatic Brain Injury (TBI): A Nationwide Cohort Study

Traumatic brain injury (TBI) is an important risk factor for dementia and is especially common among Veterans. It is unknown whether TBI exposure moderates the effect of other common medical/psychiatric comorbidities that are also important risk factors for dementia in Veterans. If treatable or preventable comorbidities are either especially common or risky in TBI‐exposed Veterans, then this may have important public health implications for dementia prevention.
