Heal Your Brain with Breathing

Breakthrough evidence out of Israel backs up what I’ve been telling my patients for years…

You can prevent, slow down – and even reverse – Alzheimer’s development using hyperbaric oxygen therapy, or HBOT.1

In the first stage of a two-part study, a team of researchers at Tel Aviv University divided mice that were genetically engineered to have Alzheimer’s into two groups.

Half the mice were given HBOT one hour a day for four weeks, totaling 20 sessions. The control mice received no treatment.

Then the brains of both groups were examined.

The researchers found that in the untreated mice:

  • Blood vessel diameters shrank, limiting blood flow to the brain
  • Existing plaques grew an average of 12% bigger
  • The number of amyloid plaques almost doubled.

However, in the mice treated with HBOT:

  • Existing blood vessel diameters remained open
  • New blood vessels formed
  • Cerebral blood flow increased
  • Existing plaques shrank 40%
  • No new amyloid plaques developed
  • Both memory and task learning increased

But the results seen in human volunteers were even more remarkable…

For the second part of the study, researchers at the Shamir Medical Center studied six patients over 65. All had early-stage Alzheimer’s with severe memory loss.

The participants were treated with 60 HBOT sessions once a day over three months. Each session included breathing 100% oxygen at two times the atmospheric pressure.

High-resolution imaging was taken before and after treatment. The scans revealed that HBOT significantly improved cerebral blood flow in several brain areas, including the hippocampus, where memories are processed and retrieved, between 16% and 23%.

Overall cognitive scores also improved, increasing from 102 to 109. And memory scores jumped a dramatic 27% – from 86 up to 100.

Poor blood flow to the brain has long been seen as an early warning sign of Alzheimer’s — but there is now strong scientific evidence

that it’s a root cause.

You see, poor blood flow restricts the delivery of lifegiving oxygen and vital nutrients to your brain.

HBOT treatment boosts oxygen levels in your brain in two ways:

    1. It allows your lungs to take in more oxygen than would be possible if you were breathing oxygen at normal air pressure. The higher pressure physically dissolves more oxygen into your red blood cells, boosting oxygen levels.
    2. HBOT also increases the synthesis of nitric oxide. This simple natural gas is one of your body’s most important signaling chemicals. Its primary function is to send “blood flow signals” that tell your blood vessels to relax. This allows more oxygen-rich blood to reach your brain. When blood vessels in your brain are inflamed and squeezed, restricting oxygen supply, HBOT opens them up.

This breakthrough study demonstrated that HBOT not only helps prevent Alzheimer’s disease but may also reverse the devastating progress of the condition.

Let the brain healing begin

Getting hyperbaric oxygen therapy is easy, painless, and effective.

At my clinic, I’ve been treating Alzheimer’s patients with oxygen for several years — and the results have been remarkable.

HBOT can be delivered in two ways – in a multi-person oxygen room or an individual unit. I use an individual chamber at my clinic. You simply climb onto a bed and relax for about an hour. A clear hood is closed over the bed. You can even watch TV or take a nap. Then you just breathe as normal.

If you’re interested in scheduling an appointment for HBOT therapy at the Sears Institute for Anti-Aging Medicine, call my staff at 561-784-7852 for details.
