'''Mental retardation''' (MR) is a generalized disorder appearing before [[adulthood]], characterized by significantly impaired [[cognitive]] functioning and deficits in two or more adaptive [[behaviors]]. It has historically been defined as an [http://en.wikipedia.org/wiki/Intelligence_Quotient Intelligence Quotient] score under 70. Once [[focused]] almost entirely on [[cognition]], the definition now includes both a component relating to mental functioning and one relating to individuals' functional [[skills]] in their [[environment]]. As a result, a person with a below-average intelligence quotient (BAIQ) may not be considered mentally retarded. Syndromic mental retardation is [[intellectual]] deficits associated with other [[medical]] and behavioral signs and [[symptoms]]. Non-syndromic mental retardation refers to intellectual deficits that appear without other abnormalities. | '''Mental retardation''' (MR) is a generalized disorder appearing before [[adulthood]], characterized by significantly impaired [[cognitive]] functioning and deficits in two or more adaptive [[behaviors]].
