Intellectual disability

Intellectual disability (ID), also known as general learning disability (in the United Kingdom),[3] and formerly mental retardation (in the United States),[4][5][6] is a generalized neurodevelopmental disorder characterized by significant impairment in intellectual and adaptive functioning that is first apparent during childhood. Children with intellectual disabilities typically have an intelligence quotient (IQ) below 70 and deficits in at least two adaptive behaviors that affect everyday living. According to the DSM-5, intellectual functions include reasoning, problem solving, planning, abstract thinking, judgment, academic learning, and learning from experience.[7] Deficits in these functions must be confirmed by clinical evaluation and individualized standard IQ testing. On the other hand, adaptive behaviors include the social, developmental, and practical skills people learn to perform tasks in their everyday lives.[8] Deficits in adaptive functioning often compromise an individual's independence and ability to meet their social responsibility.[9]
