Adult life expectancy for people with Down syndrome has risen in multiple settings. Sweden saw Down syndrome mortality rates fall by about 40% from 1980 to 2010, while the Netherlands recorded adult life expectancy increasing by about 7 years from 1986 to 2001. These gains coexist with high-frequency risks such as Alzheimer type pathology and congenital heart disease, which helps explain why lifespan outcomes vary across countries and time periods.
Key Takeaways

- Up to 90% of adults with Down syndrome show Alzheimer-type pathology by age 40–60 (pathology prevalence estimate)
- Children with Down syndrome have about a 3-fold increased risk of developing acute lymphoblastic leukemia compared with general population (relative risk estimate)
- Incidence of adult thyroid disease in Down syndrome is reported at around 15–30% (prevalence range in review)

In the UK and Europe, Down syndrome care and monitoring have improved survival, with adult life expectancy rising.
