Mental retardation is a side effect of Down Syndrome. Down syndrome or trisomy 21 (or Down's Syndrome in British English) is a chromosomal disorder caused by the presence of all or part of an extra Twenty-first chromosome. Children with Down syndrome tend to share certain physical features such as a flat facial profile, an upward slant to the eyes, small ears, a single crease across the center of the palms, and an enlarged tongue. A doctor can usually tell if a newborn has the condition through a physical exam. Down Syndrome also causes mild to moderate mental retardation.

Medical Encyclopedia: Mental Retardation Definition Mental retardation is a developmental disability that first appears in children under the age of 18. It is defined as an intellectual functioning level (as measured by standard tests for intelligence quotient) that is well below average and significant limitations in daily living skills (adaptive functioning). Description Mental retardation occurs in 2.5-3% of the general population. About 6-7.5 million mentally retarded individuals live in the United States alone. Mental retardation begins in childhood or adolescence before the age of 18. In most cases, it persists throughout adulthood. A diagnosis of mental retardation is made if an individual has an intellectual functioning level well below average and significant limitations in two or more adaptive skill areas. Intellectual functioning level is defined by standardized tests that measure the ability to reason in terms of mental age (intelligence quotient or IQ). Mental retardation is defined as IQ score below 70-75. Dictionary: mental retardation n. Subnormal intellectual development as a result of congenital causes, brain injury, or disease and characterized by any of various cognitive deficiencies, including impaired learning, social, and vocational ability. Also called mental deficiency. Neurological Disorder: Mental retardation Definition Mental retardation (MR) is a developmental disability that first appears in children under the age of 18. It is defined as a level of intellectual functioning (as measured by standard intelligence tests) that is well below average and results in significant limitations in the person's daily living skills (adaptive functioning). Sci-Tech Encyclopedia: Mental retardation A developmental disability characterized by significantly subaverage general intellectual functioning, with concurrent deficits in adaptive behavior. The causes are many and include both genetic and environmental factors as well as interactions between the two. In most cases the diagnosis is not formally made until children have entered into school settings. In the preschool years, the diagnosis is more likely to be established by evidence of delayed maturation in the areas of sensory-motor, adaptive, cognitive, social, and verbal behaviors. By definition, evidence of mental retardation must exist prior to adulthood, where vocational limitation may be evident, but the need for supervision or support may persist beyond the usual age of social emancipation. http://www.answers.com/mentally%20retarded
