Impact of mild head injury on diffusion MRI brain characteristics in midlife: Data from the PREVENT Dementia Study

Traumatic brain injury (TBI) has been associated with an increased risk of dementia, but the link between mild TBI across the life‐course remains unclear. The PREVENT Dementia study is recruiting healthy volunteers in middle age (aged 40 – 59) to identify factors that may increase their risk of dementia. This analysis assessed white matter integrity and its association with the incidence, frequency and severity of TBIs.
