Researchers led by Bruce A. Yankner, a professor of genetics and neurology at Harvard Medical School, reported that they were able to reverse the disease in mice and restore brain function with small amounts of the compound lithium orotate, enough to mimic the metal’s natural level in the brain. Their study appeared Wednesday in the journal Nature.
