Trends in stroke incidence and mortality in the Danish nationwide registries


  • The incidence of stroke did not increase in young adults between 2005 and 2018 in Denmark, while stroke mortality declined for patients of all ages.

Why this matters

  • The Global Burden of Disease Study reported that stroke incidence has declined in high-income countries between 1990 and 2010; however, other studies suggest that the trend in younger adults may be masked by declining rates in older adults, and in fact stroke incidence is stationing or increasing in those under ~45–55 years of age.

  • Understanding the potential divergence of stroke trends in people of different ages with a high-quality, large-scale, and comprehensive study is important.
