Complete 12 pages APA formatted article: Down’s Syndrome into a Mainstream Primary. Down syndrome accounts for around 5-6% of intellectual retardation, though the mental retardation in children with Down syndrome is mostly mild or moderate. There are some characteristics that make a child with this disorder easily recognizable. Children suffering from Down syndrome or mongolism as it was traditionally referred are known to have a small body stature, protruding tongue, as a result of having a small oral cavity, thick folds in the corners of their eyes and having a low muscle tone. The condition is noticed in a child either during birth or in a prenatal screening. However, the physical conditions in children suffering from this condition differs greatly, with some children with Down syndrome requiring a higher level of medical attention while some just leads a normal life (Down, 1999 p259). Though the Down syndrome condition cannot be treated, health problems related to it can be treated, more so when they are recognized earlier before a child is born and help the child to lead a better life. The condition is related to a delay in the cognitive ability of the child and a slow rate of their physical growth (Beck, 1999 p24). Facial characteristics are the most common of the observable features in a child suffering from Down syndrome.
