Intellectual disability




Intellectual disability is characterized by significant limitations in both intellectual functioning and in adaptive behavior, which covers many everyday social and practical skills. This disability originates before the age of 18. Intellectual functioning—refers to general mental capacity, such as learning, reasoning, problem solving, and communication & so on. One way to measure intellectual functioning is an IQ test. Generally, an IQ test score of around 70 or less indicates a limitation in intellectual functioning.
