How the brain clears fluid and Alzheimer-related proteins after a head injury

Brain fluid clearance and misfolded protein dynamics following traumatic brain injury

NIH-funded research Weill Medical Coll of Cornell Univ · NIH-11134653

Using brain scans, doctors will measure how well people who recently had a traumatic brain injury clear fluid and Alzheimer's-related proteins from the brain.

What this research studies

If you recently had a traumatic brain injury (TBI), this project would bring you in for advanced brain scans to track how cerebrospinal and interstitial fluids move and clear waste. You may get MRI-based clearance measurements and PET scans to look for amyloid-β, a protein linked to Alzheimer's disease. Researchers will follow your memory, thinking, and functional recovery over time and compare those results with the imaging measures. The goal is to see whether poorer fluid clearance after TBI is linked to persistent amyloid and worse recovery.

Who could benefit from this research

Good fit: Ideal candidates are adults who recently experienced a traumatic brain injury and are able to undergo MRI and PET scans and attend follow-up visits.

Not a fit: People without a history of TBI or those who cannot safely have MRI/PET scans (for example, due to pregnancy or incompatible implants) are unlikely to benefit from participating.

Why it matters

Potential benefit: If successful, this work could help identify people after TBI who are at higher risk for lingering brain protein buildup and later cognitive decline, guiding closer monitoring or future treatments.

How similar studies have performed: Animal studies and early human data show amyloid release and reduced clearance after TBI, but using serial human PET/MRI clearance measures to predict outcomes over a year is relatively new.
