Death rates rose for Alzheimer’s disease, diabetes, flu and pneumonia, and three other leading causes of death, according to numbers posted online Wednesday by the Centers for Disease Control and Prevention.

Full-year data is not yet available for drug overdoses, suicides or firearm deaths. But partial-year statistics in those categories showed continuing increases.

Just as important, there was little change in the death rate from the nation’s No. 1 killer: heart disease. In the past, steady annual drops in heart disease death rates offset increases in other causes. But that offset is no longer happening, experts say.
