Summary

This study explores whether breathing small amounts of carbon dioxide (CO2) can safely increase the movement of proteins from the brain into the blood, which may indicate better waste clearance. Researchers will compare 200 adults with and without a history of traumatic brain injury (TBI), giving each person two different CO2 levels on separate visits. The goal is to understand how CO2 affects brain waste removal, not to provide treatment.
