According to Harvard Scientists, This Missing Nutrient May Be the Key to Stopping Alzheimer’s

Study finds that lithium loss triggers Alzheimer’s, but a lithium-based compound reverses the disease in mice. What sets off the earliest chain of events that leads to Alzheimer’s disease? And why do some people who show Alzheimer’s-like brain changes never progress to dementia? These unresolved questions have challenged scientists for decades. Researchers at Harvard Medical School now believe they may have an explanation: a deficiency of lithium in the brain. “The idea that lithium deficiency could be a cause of Alzheimer’s disease is new and suggests a different therapeutic approach,” said senior author Bruce Yankner, professor of genetics and neurology in the Blavatnik Institute at HMS, who in the 1990s was the first to demonstrate that amyloid beta is toxic.
