Down Syndrome - Prognosis

The prognosis in Down syndrome is variable, depending on the types of complications (heart defects, susceptibility to infections, leukemia) of each affected individual. The severity of the developmental delay also varies. Without the presence of heart defects, about 90% of children with Down syndrome survive past their teenage years. In fact, people with Down syndrome can live until they are 50 years old.

The prognosis for a baby born with Down syndrome has improved compared to previous years. Modern medical treatments, including antibiotics to treat infections, and surgery to treat heart defects and duodenal atresia has greatly increased their life expectancy.
