A drug that restores brain metabolism in mouse models of Alzheimer's also improved cognitive function. The discovery could help researchers find additional pathways to combating the symptoms of this brain disease, beyond the telltale amyloid plaques and tau tangles that are hallmarks of Alzheimer's.A drug that restores brain metabolism in mouse models of Alzheimer's also improved cognitive function.
