Why flicker in LEDs and sound could be a good combination for the disease Alzheimer's


We’ve been writing about this subject before in flicker in LEDs but a new, exciting study tested on mice shows an interesting outcome.

That said, we’ll in this blog post illuminate why LEDs can have a positive impact for Alzheimer’s even though former speculations shows otherwise.

Which positive effects could flimmer add to Alzheimer's treatment?

This subject has been investigated before and previous research indicates how flicker could have a preventive role in an Alzheimer’s treatment. A new study, by the Massachusetts Institute of Technology, shows that “amyloid plaques”, accumulation of a damaged protein between brain cells, can have a preventive role in an Alzheimer’s outbreak if exposed to blue light with 40 hertz. It’s somewhat lower than the standard between 100 and 120 hertz but effects of visual stimulation can induce brainwaves to the extend that it contributes to a more normal brain function.

The study itself has been updated and it appears that flicker may have several positive effects on Alzheimer’s disease such as reduction in inflammation, strengthen attention, memory and protect against cell death. These tests also showed that flicker in LEDs boosted cognitive function on both younger and older mice. If you combine flicker with sound stimuli - 40 hertz tones - it showed a even more reduction in amyloid plaques. These studies also showed improvement in short-term memory, cognitive development and in the visual part of the brain.

Flicker or light therapy?

There’s shared opinions whether flicker could work as a part of Alzheimer’s treatment, others believe light therapy is the way to go. Either way, this study and results are still interesting. If the human brain respond to light as mouse does, it could have implications for interior lighting and regulatory standards.
