The two most noted abnormal structures that are suspected to damage and kill neurons in the brain in patients with Alzheimer’s are plaques and tangles. Plaques are deposits of a proteins fragment called beta-amyloid that build up in the spaces between nerve cells; and tangles are twisted fibers of another protein called tau that build up inside cells (Alzheimer 's Association Organization, 2016).
