Age-related forgetfulness may be due to a deficiency in a brain protein that helps form memories, a study found. Targeting the gene that produces that protein could lead to new therapies, the researchers said. Scientists identified the protein, called RbAp48, in human brain cells and showed that inhibiting it in mice made the animals forgetful while raising the protein improved their memories. That suggests that age-related memory loss may be reversible, researchers said.
