Could LED sources cure Alzheimer’s?

The research carried out on how light can influence the human organism, and the brain in particular, is also opening up new pathways in the treatment of important illnesses. The latest findings concern a potential new cure for Alzheimer’s disease, a neurodegenerative illness that gradually erases the memory and reduces the cognitive abilities. It is increasingly spreading as the population ages and at the moment, there are no pharmacological cures capable of stopping it.

The researchers from MIT (Massachusetts Institute of Technology), one of the most famous research centres in the world, are experimenting with a revolutionary treatment based on LED. They have used light beams and flickering emitted by LED sources to interfere with the gamma brainwaves of laboratory mice. The objective is to reduce the build-up of β-amyloid plaques, a substance considered to be the cause of Alzheimer’s disease.



The experiment, which opens up a new road in the studies on neurodegenerative illnesses, is described in an article published by the prestigious scientific magazine Nature.  Mice exposed to LED one hour a day for seven consecutive days had less plaques than mice that had not been treated. A company from San Francisco, Cognito Therapeutics Inc., has announced that it is purchasing the intellectual property rights to the research carried out by MIT with a view to selling a LED lighting system that may be able to cure Alzheimer’s in the future.

“This is a wonderful opportunity”, said Daniel Burnett, Chief Technology Officer of Cognito. “There is an urgent need to find treatments for Alzheimer’s, as at the moment there does not seem to be much we can do. If we are able to develop something that can slow down cognitive decline in patients with few side effects, it could be revolutionary.”


The researchers have stated that they will try to speed up their efforts to try out this technique on man, but warn that the effects on laboratory animals are not always confirmed when they are tested on humans.
