Down Syndrome Awareness Month – October 2020


Down syndrome occurs across the human spectrum and is the most common chromosomal condition. Each year, about 6,000 babies are born with Down syndrome — a 1 in 700 chance. 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.

5 Interesting Facts About Down Syndrome

  1. Society has changed for the better

    In ancient times, infants with Down syndrome were often killed or abandoned. And even in modern times, many people with Down syndrome were institutionalized.

  2. Pregnancy testing can pinpoint Down syndrome

    According to the Global Down Syndrome Foundation, "Down syndrome has nothing to do with race, nationality, socioeconomic status, religion, or anything the mother or father did during pregnancy." Mothers can learn through diagnostics tests during pregnancy whether or not their baby has Down syndrome.

  3. There are three types

    Of the three types of Down syndrome — trisomy 21 (nondisjunction) is most prevalent. Translocation and mosaicism account for about 5 percent of cases combined.

  4. People with Down can live full, rich lives

    An emphasis on education, a loving and stimulating home environment, and quality health care enable people with Down syndrome to have full and productive lives.

  5. Life expectancy is increasing

    As reported by the Global Down Syndrome Foundation, "As recently as 1983, the average lifespan of a person with Down syndrome was 25 years. The dramatic increase is largely due to the end of the inhumane practice of institutionalizing people with Down syndrome."
