Brain Training with 40Hz Gamma Light and Sound
New research suggests that light and sound delivered at a certain frequency —40 flashes or clicks per second — appear to restart the natural 40Hz gamma rhythm of the brain and improve the brain functions. You can see the results from the first human study published in PLOS ONE.
Separately, research has also shown that cognitive exercises could have a major effect on improving memory. The synergistic combination of 40Hz gamma light, sound and brain training games has the potential to improve the brain’s function better than either of these approaches alone.
How It Works
AlzLife delivers a combination of 40Hz light, 40Hz sound, and cognitive exercises in a single, easy-to-use, convenient package.
The Neurological Mechanism
Light and sound delivered at a certain frequency —40 flashes or clicks per second — appear to restart the natural 40Hz gamma rhythm of the brain. This gamma rhythm is essential for local neuronal communication and is associated with concentration and cognitive activity. Neurons in the cortex usually work in groups and are a bit analogous to a musical orchestra. When music instruments synchronize we hear a pleasant melody, but when they desynchronize we hear a cacophony of sounds a little like the tuning up of an orchestra. Similarly, when there is no normal brain rhythm, neurons fire out of sync and cannot generate coherent group decisions.
AlzLife is based on US Patent Pending: 62/606,112 and 62/606,476
This app has not been approved by FDA for cure, mitigation, treatment, or prevention of disease. It is intended for maintaining and encouraging a healthy lifestyle.
How To Use Your AlzLife App
We recommend using your AlzLife app for one hour a day. If the 40Hz gamma frequency flicker is too bothersome, start using the app with the 40Hz light settings set to a minimum. Most people will get used to the flicker over several sessions. If you stop noticing the flicker, you may want to increase the intensity within the app’s Setting.
The game portion of the app was specifically designed for memory and cognitive improvement. Start with games you are familiar with, then continue with as many games as possible. We recommend starting at an easy level and slowly increasing the game difficulty to a level that is challenging but not uncomfortable.
Some people who are susceptible to seizures may react negatively to gamma light. If you have had seizures in the past, we suggest that you avoid using this application before consulting your primary doctor.

Science
The proof is in the data
New study finds synergy between 40Hz stimulation and 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 including deep ones such as hippocampus which were not recruited when no cognitive task was required from the participants. The latter is of particular importance given that the hippocampal complex is considered to be one of the primary targets for Alzheimer’s disease therapies.
Results from the first human study of the effect of 40Hz light/sound stimulation have been published
Results from the first human study of the effect of 40Hz light/sound stimulation have been published. After 3 months of daily stimulation, the group receiving 40Hz stimulation showed (1) lesser ventricular dilation and hippocampal atrophy, (2) increased functional connectivity, (3) better performance on a memory test, and (4) improved sleep and measures of daily activity.
