DiscussionWithin the past decade, mortality from neurologic diseases has increased substantially, even after adjustment for age, suggesting that factors beyond population aging are contributing to this ominous trend. Vital statistics indicate that premature deaths from neurologic diseases—those occurring before age 65—have also increased since the 1990s.20 Further research is needed to identify the etiologic factors for rising mortality and to study solutions.
