For decades, Alzheimer’s disease has been seen as an unstoppable loss of memory caused by sticky plaques in the brain. Recently, powerful drugs have been created to strip those plaques away. But these drugs are also causing brain bleeds and swelling in the brain for many patients
Instead of only asking how to destroy plaques, a growing group of scientists and clinicians are asking something different: “Why does plaque build up in the first place?”
The brain has a built-in cleaning system. Your brain produces waste every day — proteins, metabolic debris, damaged cells, and inflammatory toxins. In a healthy brain, this waste is cleared away through a fluid circulation network called the glymphatic system. This system works best when:
- You sleep deeply
- Blood vessels are healthy
- Oxygen delivery is strong
- Inflammation is low
- Immune function is balanced
When these systems weaken — from aging, stress,poor sleep, toxins, infections, or poor Blood flow — waste begins to accumulate. Plaque in the brain isn’t just the cause of Alzheimer’s. It is also a sign of cleanup failure.
HYPERBARIC OXYGEN THERAPY: FEEDING THE BRAIN
Hyperbaric Oxygen Therapy places a person in a pressurized chamber where they breathe concentrated oxygen. This allows up to 10–15x more oxygen to dissolve into the blood plasma and reach the brain.
When the brain receives more oxygen:
• Blood vessel growth improves
• New neural connections form
• Inflammation quiets down
• Mitochondria (cell batteries) revive
• Tissue repair accelerates
Across multiple international trials, HBOT has shown benefit in:
• Memory scores
• Attention
• Processing speed
• Daily functioning
• Mood and sleep quality
A major 2024 review that analyzed 11 controlled studies involving nearly 850 Alzheimer’s patients found that those receiving HBOT showed significant improvement in cognitive tests and daily activity compared to standard care.
Other imaging studies show improved glucose metabolism and brain blood flow after repeated HBOT sessions — meaning the brain begins to use energy more efficiently again.
Patients often report:
• Mental clarity
• Better sleep
• Stronger mood
• Sharper focus
• Improved stamina
NEUROFEEDBACK: TRAINING THE BRAIN BACK TO BALANCE
During a therapy session, sensors read the brain’s electrical activity and when the brain shifts into healthier patterns, it receives positive feedback. This allows the nervous system to re-learn balance.
Alzheimer’s disrupts:
• Memory networks
• Attention rhythms
• Emotional regulation
• Sleep cycles
Neurofeedback helps restore these cycles. People with mild cognitive impairment and Alzheimer’s report:
• Improvement in short-term memory
• Better attention
• Improved speech fluency
• Reduced agitation
• Improved sleep patterns
Brain scans show changes in brain cell connectivity after training — meaning the brain doesn’t just feel better… it functions differently. Families often notice:
• More alert conversation
• Better emotional stability
• Less confusion
• Increased engagement
• Improved independence
