Area of Science:

  • Gerontology
  • Public Health
  • Epidemiology

Background:

  • Dementia prevalence is projected to rise significantly in Canada.
  • Alberta is expected to experience the largest relative increase in dementia cases nationwide.
  • This study addresses the need for localized dementia data in Alberta.

Purpose of the Study:

  • To determine the prevalence and incidence of diagnosed all-cause dementia in Alberta, Canada.
  • To analyze dementia trends between 2014 and 2022.
  • To inform future planning for dementia support services.

Main Methods:

  • Utilized population-based administrative health data for individuals aged 65+ in Alberta.
  • Employed a validated case ascertainment algorithm for dementia diagnosis.
  • Reported annual prevalence and incident cases from April 1, 2014, to April 1, 2022.

Main Results:

  • Dementia prevalence in Alberta increased by 45% (30,050 to 43,802) from 2014 to 2022.
  • Incident dementia cases rose by 27% (6,884 to 8,741) over the same period.
  • The dementia incidence rate decreased from 1.48 to 1.37 per 100 person-years (p < 0.001).

Conclusions:

  • Both prevalent and incident dementia cases significantly increased in Alberta (2014-2022).
  • The incidence rate of dementia showed a statistically significant decline during this period.
  • Findings underscore the critical need for enhanced planning of dementia care and services in Alberta.
