Can red-light therapy treat brain injuries? Some research shows ‘striking’ results

Larry Carr and his wife, Laurie, got into a terrible fight. It was 2010. He remembers that he yelled and yelled. She left, trying to gather her own emotions. Alone with his thoughts, Carr felt he had reached a bottomless abyss.

“Broken,” he says.

No one understood what was happening to him. Out of nowhere, he’d explode in anger. Paranoia and depression hounded him. Laurie tried to tiptoe around his emotions, unsure what might trigger an outburst. He didn’t resemble the man who had been her high school sweetheart — even-keeled, playful. Logical. He held a Ph.D. in physiology/exercise physiology. He had been a star middle linebacker for BYU’s football team in the 1970s, still holding the record for tackles per game over a career.
