Down syndrome is the most prevalent chromosomal cause of intellectual disability and the most common congenital disorder associated with intellectual disability. It occurs in an average of 1 out of every 700-1000 births. It affects both males and females of all ethnic and socioeconomic backgrounds. Individuals with Down syndrome have characteristic facial features. The syndrome results in higher than normal risk for associated medical conditions, as well as distinctive cognitive, language, and behavioral profiles. In general, persons with Down syndrome have higher levels of adaptive behavior than of intelligence. The syndrome results in an life span that is shorter than average, but it has quintupled over the last century due to advancements in treating associated medical conditions, especially heart defects.
