Caption: Neurologists finally have an answer to one of the most important questions about Alzheimer's disease: In a study published in Science Express, researchers show that rising brain levels of a plaque-forming substance occur not because the brain makes more of the substance but because it can no longer clear the substance as well. The results are likely to aid efforts to improve diagnosis and treatment.
