CO2 Breaths May Help Clear Alzheimer's Brain Waste, Early Study Finds
TL;DR Summary
Researchers presented small 2025 findings showing brief CO2 pulses delivered via masks can activate the brain's glymphatic clearance, boosting cerebrospinal fluid inflow and evacuating proteins such as tau (with higher amyloid beta in blood), suggesting a potential non-invasive approach to address Alzheimer's pathology. However the study is preliminary and larger trials are needed to assess safety, long-term effects, and cognitive outcomes; not a clinical therapy yet.
