Down Syndrome is a genetic disorder that occurs when an individual has an extra copy of chromosome 21. The additional genetic material changes the development of a child and causes the characteristics that are most commonly associated with Down Syndrome. Common traits of Down Syndrome are small stature, lower muscle tone, and an upward slant to the eyes.
Down Syndrome can be diagnosed prenatally or at birth. Prenatal screening tests can estimate the chance of a fetus having down syndrome, but cannot tell you for sure. Diagnostic tests provide a definite diagnosis. When Down Syndrome is identified at birth it is by the presence of the certain physical traits. Karyotype, a chromosomal analysis, is done to confirm the diagnosis.
There is not a single treatment for Down Syndrome. Instead each individual is treated based on his or her needs. A child with Down Syndrome will most likely receive treatment and care from physicians, special educators, speech therapists, occupational therapists, physical therapists, and even social workers. People with Down Syndrome sometimes take drug supplements to control brain activity. It is also common for those with Down Syndrome to use assistive devices.
