Strengthen Your Brain’s Natural Rhythm

Think of your brain as an orchestra finding its rhythm. This natural rhythm, specifically at 40 cycles per second (40Hz), is vital for keeping your mind sharp and focused.

Recent research has revealed something remarkable: it’s possible to help restore this rhythm using precisely timed light and sound. Early human trials have validated the potential of this approach.

Scientists also know that cognitive exercises strengthen memory. By combining these exercises with 40Hz stimulation, AlzLife offers a powerful new way to support your brain health.

How It Works

Your brain’s natural 40Hz rhythm is vital for memory, focus, and cognitive health. AlzLife helps support this rhythm by combining three proven approaches in one simple app. While 40Hz light and sound gently play in the background, you engage with brain games, guided meditations, educational videos, or even read a book — all precisely timed to stimulate healthy brain activity.
AlzLife is based on US Patent Pending: 62/606,112 and 62/606,476

What research says about 40Hz light and sound stimulation

New Study: 40Hz Stimulation Combined with Cognitive Activities

New study finds synergy between 40Hz stimulation and cognitive activities. Inclusion of a cognitive task during the 40Hz stimulation not only has a positive effect on the strength and extent of the gamma entrainment, but also promotes the propagation of gamma entrainment to additional neural areas…

These findings suggest that combining cognitive activities with stimulation may enhance its effectiveness.

Published results: First Human Study of 40Hz Light & Sound Stimulation

The first human study on 40Hz light and sound stimulation showed promising results. After three months of daily sessions, participants receiving 40Hz stimulation experienced measurable benefits:

  1. Less ventricular dilation and hippocampal atrophy
  2. Increased functional brain connectivity
  3. Better performance on memory tests
  4. Improved sleep and daily activity

TED Talk: Could We Treat Alzheimer’s with Light and Sound?

In her TED Talk, Prof. Li-Huei Tsai presents pioneering research on how 40Hz light and sound stimulation may reduce Alzheimer’s-related brain changes.

She explains how sensory stimulation can activate healthy brain rhythms, potentially supporting memory and cognitive health.

This research helped inspire the development of AlzLife’s approach to cognitive wellness.

Device compatibility

The 40Hz light stimulation requires a high refresh rate display (90Hz or above). On devices with lower refresh rates, 30Hz will be used instead, which may be less effective. The 40Hz audio and all cognitive games will continue to work normally. See our FAQ for a list of compatible devices
