Light Therapy Will Help Treat Alzheimer's Disease »GoGetNews News


In 2015, a neuroscientist from Boston found that the effects of flickering light on the eyes of mice suffering from dementia stop the death of nerve cells in the brain for one hour a day, destroying clots of dangerous protein. Although the results were considered reliable, scientists were skeptical of this method for a long time, doubting that it would work for people. But now a team of specialists from the Massachusetts Institute of Technology has published the results of its new research, confirming the effectiveness of light therapy in the fight against neurodegenerative diseases.

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.
