MIT Researchers Show Light Treatment May Help Prevent Alzheimer's Disease

Researchers at MIT, led by Professor Li-Huei Tsai, director of MIT’s Picower Institute for Learning and Memory, released a study in the journal Nature Wednesday that could indicate new ways to prevent Alzheimer's. The study found a particular frequency of light reduces beta-amyloid plaques in the brains of mice, a substance thought to cause Alzheimer's disease.
