Down Syndrome

Understanding Down Syndrome

Down syndrome is the most common and readily identifiable chromosomal condition associated with intellectual disability. Down syndrome is caused by a chromosomal abnormality, occurring when an individual has three, rather than two, copies of the 21st chromosome. The extra chromosome changes the orderly development of the body and brain, causing increased risk for certain medical conditions.

The exact causes of the chromosomal rearrangement and primary prevention of Down syndrome are currently unknown. Down syndrome is not related to race, nationality, religion, or socioeconomic status.  Children born with Down syndrome experience a wide variation in mental abilities, behavior, and physical development. Individuals with Down syndrome have their own unique personality, capabilities, and talents. They benefit from early intervention, inclusive education, appropriate medical care, and positive public attitudes.
