Clinical and Biological Measures of TBI-related Dementia Including Chronic Traumatic Encephalopathy (R01 Clinical Trial Not Allowed)

archived

This FOA invites investigation of biological and clinical measures of TBI-related progressive neurodegeneration and neurocognitive decline associated with increased risk for dementia and /or traumatic encephalopathy syndrome (TES) (clinicopathologic diagnostic counterpart to the neuropathological diagnosis of Chronic Traumatic Encephalopathy (CTE)). Investigations should be based on existing, well-characterized populations of patients with a history of TBI that are enriched for increased risk of cognitive impairment or dementia and can continue to be followed longitudinally; additional subjects may be recruited as appropriate. The overall goal is to advance knowledge of the underlying pathophysiology and clinical characterization of the chronic effects of TBI that distinguish static-chronic TBI cognitive impairment from those that lead to progressive neurodegeneration associated with TES and dementia. A critical feature of this FOA includes the broad sharing of clinical, neuroimaging, physiological, and biospecimen data and to create a data and associated biofluid resource for the broader community to further advance research in this area.
