- Intermittent inhalation of high carbon dioxide for 30 minutes flushes Alzheimer's-linked proteins from the brain by mimicking deep sleep's vascular pumping action.
- The method activates the glymphatic system, which removes waste like beta-amyloid and tau, potentially benefiting conditions like Parkinson's by clearing alpha-synuclein.
- A study with 12 participants showed increased blood levels of beta-amyloid post-intervention, suggesting enhanced brain clearance, but benefits returned to baseline after about an hour.
- Safety appears favorable with no side effects, and future research will explore long-term impacts, frequency needs, and potential portable home devices for broader applications.
