The prevalence of Down syndrome increases with the mother’s age. It is associated with delays in physical growth, characteristic facial features and intellectual disability. In fact, the average IQ of an adult with Down syndrome is equivalent to that of an 8-year-old.These are just facts, and like all facts, they can fail to provide a full picture. The truth is that children born with Down syndrome can absolutely go on to live happy and long lives. And with Down Syndrome Awareness Month every October, we can be inspired to learn more about this topic and to celebrate people born with Down syndrome and the medical advancements that increasingly improve their quality of life.
