According to experts, light therapy works by targeting a chemical that promotes the formation of toxic protein clumps, and this method is likely to be much more powerful than previously thought. Using light therapy, scientists were able to improve cognitive skills and spatial memory in mice with dementia. Researchers believe that this method can be successfully applied in humans.

In addition to the destruction of protein clusters with the use of light therapy, experts have recorded signs of improvement in many parts of the brain – strengthening neurons and immune cells, as well as reducing inflammation. It was found that after therapy, the mice coped better with the passage of the water maze. According to the data obtained, light disrupts the activity of two types of proteins (tau P301S and CK-p25), as a result of which Alzheimer's disease stops developing. It is noted that untreated mice that were not treated with light, lost up to 20% of neurons in the brain. In the future, after an autopsy of the rodent brain, experts found that light therapy stopped the further development of Alzheimer's disease.
