People who experience stroke have limited therapeutic options, but new research by investigators from Massachusetts General Hospital reveals the potential for non-invasive light treatment using lasers. The results are published in Stroke.

"Unlike other approaches using chemicals, which can be toxic to our bodies, laser light is a physical parameter. It does not stay in the body after the therapy and will have little chance of causing side effects," said co–senior author Satoshi Kashiwagi, MD, Ph.D., an investigator in the Department of Radiology at Massachusetts General Hospital and an assistant professor of Radiology at Harvard Medical School.
