Transforming Research and Clinical Knowledge in Geriatric Traumatic Brain Injury (TRACK-GERI)

Transforming Research and Clinical Knowledge in Geriatric Traumatic Brain Injury (TRACK-GERI)

The purpose of this study is to improve the diagnosis and prediction of recovery after traumatic brain injury (TBI) in adults age 65 years and older. The study will follow older adults who present to the emergency department after TBI, as well as matched control participants, and will measure clinical features, brain imaging, and blood-based biomarkers over 12 months to understand how recovery changes over time. Researchers will examine how pre-injury health, brain structure, and biological markers are related to disability and cognitive outcomes after TBI. Information from this study will be used to develop age-appropriate tools to better diagnose TBI and estimate long-term outcomes in older adults.

4. Low likelihood follow-up (participant or family is indicating a low interest, homelessness, out of state/country)
5. Current participation in an interventional trial
6. Penetrating TBI
7. Spinal cord injury with ASIA score of C or worse
