The goal of this project is to define the biomarker profile of TBI-associated cognitive impairment CI in veterans and compare it to that of veterans with Alzheimers Disease AD and to age-matched controls. Our overall hypothesis is that TBI-associated CI involves a unique biomarker profile that has features distinguishable from AD and normal aging. Specifically, we hypothesize that 1 patients with TBI associated CI will have higher phospho-tautotal tau ratio than controls who have not had a TBI, and that 2 TBI-associated CI will be associated with elevations in inflammatory markers compared to controls and 3 a decrease in b-amyloid measures compared to controls but not as low as in the setting of AD. We currently have data collection ongoing at both sites. As of 30-SEP-2016, data from 134 participants has been collected 65 TBI, 48 controls, and 21 with AD and no TBI. Once data collection is complete, we will examine the biomarker profile of the groups. This study will refine our understanding of the underlying mechanisms in TBI-associated CI, help predict who is at greatest risk of developing CI in veterans with TBI, and identify who may benefit from interventions and treatment for CI and its prevention.
