Intellectual deficit

Intellectual disability (ID), also known as general learning disability and formerly mental retardation (MR), is a generalized neurodevelopmental disorder characterized by significantly impaired intellectual and adaptive functioning. It is defined by an IQ under 70, in addition to deficits in two or more adaptive behaviors that affect everyday, general living. [Source: Wikipedia ]
