40Hz pulsing helps Alzheimer’s Disease

McDermott B, Porter E, Hughes D, et al. Gamma Band Neural Stimulation in Humans and the Promise of a New Modality to Prevent and Treat Alzheimer's Disease. J Alzheimers Dis. 2018;65(2):363–392. doi:10.3233/JAD-180391

This is a fascinating article which talks about the importance of a particular kind of brainwave called gamma waves, which range from around 30 to 100Hz. 

When you are concentrating, thinking, learning and using your memory with very focussed attention, the gamma waves are working hard in your brain. In Alzheimer’s disease, it looks like the brain doesn’t spend anywhere near as much time enjoying gamma waves, and this then means that it becomes difficult to concentrate, think and remember things. 

In an animal model, there is evidence that having a 40Hz pulse applied over a specific area can change the way that the brain works, and in particular, help the brain to collect and chuck out the garbage that collects in the brain. There is a theory that not putting out the brain garbage is one of the reasons that Alzheimer’s disease develops. 

It seems that 40Hz, which is in the gamma range, is a particularly good garbage collector. 

Because of this work, our Coronet uses 40Hz pulsing, and yes, it pulses right over that specific area of the brain.
