This longitudinal population-based study explores trends in declining dementia rates using health care administrative data from the Canadian Institute for Health Information for the province of Ontario, Canada.

Stroke and dementia pose significant threats to the adult brain and share the same treatable risk factors. Stroke incidence in high-income countries has been declining, coinciding with better risk-factor control. However, hitherto there have been encouraging trends, but no proof, of declining dementia incidence. To address this, we analyzed health care administrative data from the Canadian Institute for Health Information for the province of Ontario, Canada.
