Human Trials Show Promising Results for 40Hz Light and sound in Slowing Alzheimer’s

The latest news is exceptional in that these investigations focused on replicating the positive results found with mice now with humans’.

At the Alzheimer’s Association International Conference last year, positive reports were published on a pair of studies where Alzheimer’s patients were exposed to one hour each day of 40Hz light and sound over a period of weeks.

The goal of the light and sound therapy was to boost and reinvigorate  a rhythmic brain wave frequency called gamma waves. Gamma frequency is known to slow down in the Alzheimer’s brain.

Amyloid plaque buildup in the brain has long been considered a key factor in the development and progression of Alzheimer’s disease.

Scientists have been working to develop drug therapies to attack and reduce the Amyloid Beta plaque build up. Historically pharmaceutical therapies for Alzheimer’s have been challenged and controversial at best.

This latest research focused on a drug-free non-invasive approach.

Both research studies were led by scientists at the Picower Institute for Learning and Memory at the Massachusetts Institute of Technology.

These scientists pioneered research and development of 40Hz stimulation in the Alzheimer’s brain.

“One study conducted testing on people with mild Alzheimer’s disease. Individuals were exposed to light and sound therapy for 1 hour daily. After three months, the test group brain scans revealed improved brain wave potency, while signs of Alzheimer’s-related brain degeneration slowed. The test group also performed better on face and name recognition tests. “

“The second study focused on patients with mild to moderate Alzheimer’s disease and similarly exposed them to daily, 60-minute, 40Hz light and sound therapy. This team determined that while brain degeneration linked to Alzheimer’s continued to progress within the test group, it did so 65% more slowly compared to similar stage patients with no 40Hz therapy.  “

Alzheimer’s disease (AD) is associated with alterations in cortical perfusion that correlate with cognitive impairment. Recently, neural activity in the gamma band has been identified as a driver of arteriolar vasomotion while, on the other hand, gamma activity induction on preclinical models of AD has been shown to promote protein clearance and cognitive protection.


In two open-label studies, we assessed the possibility to modulate cerebral perfusion in 15 mild to moderate AD participants via 40Hz (gamma) transcranial alternating current stimulation (tACS) administered 1 h daily for 2 or 4 weeks, primarily targeting the temporal lobe. Perfusion-sensitive MRI scans were acquired at baseline and right after the intervention, along with electrophysiological recording and cognitive assessments.

40hz light could prevent alzheimers


No serious adverse effects were reported by any of the participants. Arterial spin labeling MRI revealed a significant increase in blood perfusion in the bilateral temporal lobes after the tACS treatment.

Moreover, perfusion changes displayed a positive correlation with changes in episodic memory and spectral power changes in the gamma band.


Results suggest 40Hz tACS should be further investigated in larger placebo-controlled trials as a safe, non-invasive countermeasure to increase fast brain oscillatory activity and increase perfusion in critical brain areas in AD patients


More than 12 million people are projected to develop Alzheimer’s by the year 2050 in the USA. This research report provides all of us with data-driven hope to prevent Alzheimer’s disease. 

Today, there are almost 6 million Americans over the age of 65 living with Alzheimer’s and the risk of dementia is rising.


Meanwhile the boss of the World Health Organisation, a proxy of Bill Gates, has overruled all advisers to declare a Worldwide State of Emergency due to a marginal monkeypox outbreak.

6 million of us with Alzheimers are neglected. Not one person has yet died from Monkeypox in the United States, but media fear porn abounds and lucrative vaccine contracts are already approaching Billions of dollars.

Alzheimer’s In Mice Reversed Using Light and Sound Only.. could be Simple At-Home 1 hr a day Cure

Good news?.. a simple non invasive drug free treatment for Alzheimer’s.. if it works on us Humans.. So lets try it out!! This begs the question ‘So what wavelengths could be CAUSING Alzheimer’s and a host of other diseases??’ And it supports the evidence that the ocean of electromagnetic frequencies we now inhabit may be a cause of cancer, heart disease, etc. see here..Shock Study shows Blocking WiFi, Mobile, emissions etc (EMF radiation) Improves Autoimmune Diseases, etc even BEFORE 5G blitz

Alzheimer’s disease is a condition which is a form of dementia, that affects around 44 million people around the world, with an estimated 5.5 million people in the US alone. And there is no real cure for the disease, though some drugs can stall the onset of Alzheimer’s, there is nothing that can stop it from progressing. It is also the 6th leading cause of death in the US, more potent than people killed by breast and prostate cancer combined.

Virtually all new treatments have failed in clinical trials. Shannon Macauley, a neuroscientist at Wake Forest School of Medicine says, “We really don’t have much to offer people.”

Those who have loved ones with the disease know the stress and difficulty that comes with it, some eventually lose hope and their ability to continue living with their stricken loved ones. It is sad and unfortunate, but a reality. But there is some research going on that may bring hope for the afflicted and their families.

Educate Inspire Change

Neuroscientists at MIT seem to be making progress in a simple yet “magical” project. It involves work imitating the healthy rhythmic patterns, or brain waves, that operate at different frequencies. Gamma brain waves oscillate between 30 to 100 Hz and are known to decrease in the brains of people suffering from Alzheimer’s.

The study experimented on mice suffering from the disease by flashing light 40 times a second into their eyes, which treated their Alzheimer’s. Another amazing part of the study was that added sound of a similar frequency dramatically improved the results. It seems the truth about healing frequencies is now being more appreciated.

The non-invasive treatment also reduced the number of amyloid plaques found in the brains of these mice. The plaques that were cleared affected cognitive functions such as memory and learning. Li-Huei Tsai, one of the MIT researchers said, “When we combine visual and auditory stimulation for a week, we see the engagement of the prefrontal cortex and a very dramatic reduction of amyloid.”

However, the study also pointed out that mice treated for one week, and then performing the tests after another week, showed that the positive effects faded. This means that the treatment needs to be given continuously to benefit the subjects.

Tsai used a frequency ranging around 40 Hz, which is a sound just high enough for humans to hear. A side effect was that it also helped clear the nearby hippocampus, an essential area of the brain associated with memory. The treated mice seemed to perform better in a range of cognitive tasks. The findings showed an overall neuroprotective effect, even in the later stages of neurodegeneration.

Science News

Whether the same effects can be achieved from mice to men is still something that is being studied. Nancy Kopell, professor of mathematics and statistics at Boston University explained, “Though there are important differences among species, there is reason to be optimistic that these methods can provide useful interventions for humans.”

Sure, more studies are needed, but the future looks “bright” for those suffering from Alzheimer’s. Hopefully it works just as good with us humans.

note: Try it yourself if your memory is going. But lets remember that many US research studies are by now cruel false scams. However this therapy does not rely on experimental vaccines or often useless patent medications costing thousands of dollars a pop. Serious research published in ‘Nature’ does show some benefits and no side effects.. But it could also be a way to sell millions of Alzheimer victims 40hz Sound and Light emitters!
