Alzheimer’s Awareness Month: How 40Hz Gamma Stimulation Could Support Brain Health

Intro:

Every brain deserves attention. Especially in June.

Every June, Alzheimer’s Awareness Month brings much-needed focus to one of the most complex neurological disorders affecting millions worldwide. Alzheimer’s is more than memory loss — it’s a progressive condition that disrupts families, burdens caregivers, and challenges medical science.
And while there’s still no cure, new discoveries are paving fresh pathways toward hope and support.

One of the most promising?

Gamma wave stimulation at 40Hz.
And yes — it’s already available in the neuroVIZR app as part of our wellness-focused journeys.

What’s the science behind 40Hz?

In March 2025, researchers at MIT’s Picower Institute for Learning and Memory published compelling findings that further validate the benefits of 40Hz gamma-frequency stimulation on brain health.

This approach — also known as GENUS (Gamma Entrainment Using Sensory stimulation) — uses light, sound, and vibration to stimulate the brain at 40Hz, the same frequency as healthy gamma brain waves associated with attention, perception, memory, and cognition.

New evidence shows that 40Hz stimulation may:

• Reduce inflammation in the brain a key factor in the progression of Alzheimer’s
  

• Preserve brain structure, particularly in the hippocampus, a region central to memory
  

• Enhance gene expression linked to cellular repair, neuroprotection, and longevity
  

• Increase glymphatic activity, supporting the brain’s waste-clearance system
  

• Trigger glial cell activation (astrocytes and microglia), which protect and clean the brain
  

• Improve brain-wide communication by restoring synchrony between key neural circuits
  

• Stimulate VIP peptide release, supporting brain rhythm regulation and inflammation control
  
  

The study reinforced that daily exposure to 40Hz light and sound helped reduce harmful amyloid plaques and tau tangles in preclinical models. These proteins are hallmark features of Alzheimer’s that disrupt neuron function and accelerate decline.

Not just in mice early human results are promising too

MIT researchers and collaborators, including Cognito Therapeutics, have translated these results into human clinical trials. Early-phase studies have shown that one hour a day of 40Hz light and sound stimulation is:

✅ Safe and well tolerated, even in patients with early-stage Alzheimer’s
✅ Associated with slower brain shrinkage, especially in memory-related regions
✅ Linked to improved sleep, better memory recall, and enhanced neural connectivity

One study even showed changes in white matter integrity — suggesting that 40Hz could help preserve the brain’s communication pathways.

Meanwhile, international researchers are exploring gamma stimulation for related conditions like Parkinson’s, Down syndrome, chemo brain, multiple sclerosis, stroke recovery, and more.

Why this Matters for you and your Loved Ones?

At neuroVIZR, we’re inspired by this research and have integrated 40Hz Gamma Stimulation into select programs in our app.
These aren’t medical treatments, but evidence-based wellness experiences designed to gently support:

Cognitive clarity
Mental focus
Resilience in daily brain rhythms
Better sleep support
A more energised, present mind

Think of it as your personal brain gym, based on leading neuroscience:

• Passive, drug-free, and non-invasive
  

• Supports your brain’s natural gamma rhythms
  

  •  Grounded in the science of neuroplasticity and photobiomodulation
    

No wires. No diagnostics. Just your phone, your senses, and a few minutes of focused light and sound.

Explore 40Hz for yourself

With just a few minutes a day, you can begin to entrain your brain toward a clearer, more resilient state.

Our app’s 40Hz sessions use synchronised light and sound to provide a calming, immersive experience. Early users often report feeling:

More centred and calm
Mentally sharper
Ready to rest more deeply
Even just five minutes a day may help regulate your mind and reset your focus.

Brain health is for everyone not just those diagnosed

Alzheimer’s Awareness Month is more than a moment to remember those affected — it’s a reminder to protect what matters most: the power of your own mind.

Whether you're supporting a loved one, proactively investing in your cognitive health, or simply curious about the future of brain wellness, 40Hz stimulation may be a powerful piece of your toolkit.
