Living With Alzheimer's Or Dementia? Meet EVY.
EVY may help families live well with the disease and potentially bring about more good days.








Alzheimer’s Disrupts Brain Signals. 40Hz May Help.
EVY is a general wellness device that may help families live well with the disease and potentially lead to more good days.
Early Stages
A name they can’t place. A familiar route that is now unfamiliar. The same question asked five times in ten minutes. Misplaced items.
Middle Stages
Grandchildren become strangers. Meals get forgotten. Bathing becomes a battle. Independence begins to fade. The need for daily help begins.
Late Stages
Socializing has disappeared. Dependency on others for basic functions is the norm. Comfort and steady presence become what matters most for them and for you.
How 40Hz Reaches Your Brain and What It Does
How 40Hz Reaches Your Brain
40Hz can be delivered through light and sound, entering the body through the eyes or ears to support healthy brain activity.
Multi-sensory stimulation — light and sound working together to support your brain.
What 40Hz Does Inside Your Brain
When 40Hz is activated, neurons may fire in synchrony, potentially clearing amyloid plaques and tau tangles linked to Alzheimer’s.
When 40 Hz stimulation activates, scattered brain waves gradually align into a synchronized rhythm.
How 40Hz Reaches Your Brain and What It Does
40Hz reaches your brain through light and sound, then triggers the cellular activity that supports it.

Real Families. Real Results.
Caregiver’s Story
Watching Mom Return to Herself
“She just seemed like her old self. My sister said the exact same thing. She’s like, oh, mother’s doing great. I’m just loving how she’s changing, going back to her own self.”
— Terry
After Terry’s mom progressed from mild cognitive impairment to Lewy Body dementia, Terry wanted to do anything to help her feel like herself again. Within a couple weeks of using EVY, her mom started participating in conversations and even improved in her strength training sessions. Terry says the cost doesn’t compare to the support it provides.

Personal Story
Battling Early Stage Alzheimer’s
“We may have a dementia diagnosis, but we’re still people with dreams, with friendships, with family, with things that we want to accomplish in our lives.”
— Cynthia
After being diagnosed with early stage Alzheimer’s, Cynthia decided to take a proactive approach rather than wait for the disease to progress. She discovered EVY as a non-pharmacological option to potentially slow her cognitive decline. Now EVY is part of her daily routine: she comes home from her morning swim, pours coffee, and turns on her light while she works. For Cynthia, it’s about celebrating good days and navigating the journey with hope. She calls it “wonderful to have this in the toolbox” and hangs her hat on hope every day.

Wife’s Story
Staying Static Instead of Declining
“Before the light came along, we were going downhill. I don’t know where we’d be if we hadn’t found this two years ago. That’s kind of a scary thing to say.”
— Wife of Marty
When her husband Marty started forgetting things, she thought he just wasn’t listening. It turned out his short term memory was declining. She wanted something non-invasive that fit their lifestyle. After two years with EVY, Marty has remained static instead of declining. She calls it a game changer and says the cost is “pennies when you think about what it has done for us.”

Frequently Asked Questions
What is 40 Hz Light Stimulation?
40 Hz light stimulation is a therapeutic approach that involves exposing individuals to light flickering at a frequency of 40 hertz (Hz), where the light blinks on and off 40 times per second. This technique is primarily explored for its potential benefits in treating Alzheimer’s disease. The key aspects of 40 Hz light stimulation include:
- Gamma Rhythms Restoration: The therapy aims to stimulate the brain and restore gamma rhythms, which are important for cognitive functions and are often disrupted in Alzheimer’s patients.
- Reduction in Alzheimer’s Pathology: Studies have shown that 40 Hz stimulation may reduce the levels of amyloid and tau proteins in the brain, which are hallmarks of Alzheimer’s pathology.
- Improvement in Cognitive Functions: Preliminary studies indicate that this therapy may improve cognition and preserve synapses in Alzheimer’s patients.
- Non-Invasive Nature: As a non-invasive therapy, it delivers sensory stimulation through light and sound, offering a safer alternative to more invasive treatments.
- Potential for Widespread Application: Ongoing research and clinical trials are exploring the broader applicability and effectiveness of this therapy in treating Alzheimer’s disease.
