What about 40 hz audio and visual stimulation?
Some of us know of that MIT article that was released a while back about using 40 hz light stimulation by flickering an led strip at 40 hz. This showed to reduce Abeta levels in the genetically modified lab subjects.
"the researchers used light flickering at 40 hertz, delivered for one hour a day. They found that this treatment reduced levels of beta amyloid plaques and another Alzheimer’s-related pathogenic marker, phosphorylated tau protein. The treatment also stimulated the activity of debris-clearing immune cells known as microglia."
They used a 40 hz audio tone:
" In their new study, the researchers set out to explore whether they could reach other brain regions, such as those needed for learning and memory, using sound stimuli. They found that exposure to one hour of 40-hertz tones per day, for seven days, dramatically reduced the amount of beta amyloid in the auditory cortex (which processes sound) as well as the hippocampus, a key memory site that is located near the auditory cortex."
" They also found that auditory treatment induced changes in not only microglia, but also the blood vessels, possibly facilitating the clearance of amyloid."
Then they combined both 40 hz light + 40 hz audio tone:
"The researchers then decided to try combining the visual and auditory stimulation, and to their surprise, they found that this dual treatment had an even greater effect than either one alone. Amyloid plaques were reduced throughout a much greater portion of the brain, including the prefrontal cortex, where higher cognitive functions take place. The microglia response was also much stronger."

Then there is the anecdotal side of things of people trying this. If you take a look at this link I will post this guy who has a website with that covers this area. He created a tone generator which can produce a range of audio tones including 40 hz. He notes that an individual contacted him explaining he used his tone generator to create a 40 hz tone and his family member who has AD apparently showed improvement. If you look at the comments on his website other individuals have claimed to try this method a playing a 40 hz tone and noticed what appears to be improvements in their family members with AD as well.
Cool thing is he lists ways to do this and some cautionary stuff like this is still experimental, becareful, etc probably to cover his a$$ but its fascinating.

My point for this is despite the anecdotal claims this could be added to the protocol simply because it targets AD pathology. Also, this approach is very easy to do. Its super accessible to anyone with a laptop/computer, computer speakers and internet. Importantly, its very inexpensive to do and seems to be harmless. Seems to be.
Youtube has plenty of 40 hz audio tones but its probably best to use his audio tone generator because it seems more...accurate? You can pick various "tones" as well. Sine, wave, square, sawtooth. Its best to use Sine in my opinion because its a low rumble as opposed to the other options which are more harsh to listen to.
As for the 40 hz light stimulation....there is this company that has produced a light bulb that fiickers at 40 hz just like in the experiment. They also have an MP3 players which is preloaded with a 40 hz tone that you can listen too ( but this woudl be through headphones and not larger external speakers )

Youtube also has videos of 40 hz light flicker for free. In fact, they one that is has 40 hz light flicker with a 40 hz audio tone. So I suppose one could use that and simply stare at the screen or keep it in ones peripherial vision...or hook it up a large tv and keep it in ones peripherial vision
Also, if someone has some money they could opt for a high end subwoofer which would ( most definetly ) produced a ( very i.e louder ) audible 40 hz tone. It would be loud low rumble. Might even shake the room.
Its just so easy and accessible and cheap to do. You just play the tone through some external speakers in the background or nearby ( which ever is preferred ) and can include the 40 hz light flicker in your line of sight or peripherally for an hour ( same design as done by the MIT folks )
Opinions?
