Incidence of dementia over a period of 20 years in a Norwegian population.

ABSTRACT:

Introduction

In Norway, the prevalence of dementia is higher than in demographically comparable, high income countries, but reliable incidence studies are lacking. This study calculated the incidence of age-specific dementia from 2000 to 2019.

Methods

Participants from The Tromsø Study (n = 44,214) were included. Participants with a dementia diagnosis (n = 2049 cases) were identified. Poisson regression was used to calculate age-specific yearly and 5-year incidence rates from 2000 to 2019.

Results

The incidence of dementia has decreased from 2000 to 2019. The trend was highly significant for ages of 60-99 years, and was similar for both sexes.

Discussion

The incidence of dementia in North Norway has decreased over the past two decades similar to t
