Alzheimer’s disease is a growing cause for concern in the world today. In the US alone, about 5 million people are reported to be affected. And that number is predicted to grow even more in the very near future. And as there is no known cure for it, Alzheimer’s patients and their families are left to resort to treatments that are usually expensive and, in the long run, only temporary. Researchers at MIT, however, may have come across a possible new mode of treatment that shows promising results. And it involves nothing more than flashing LEDs lights at eyes.
