Borderline intellectual functioning

Borderline intellectual functioning is a categorization of intelligence wherein a person has below average cognitive ability (an IQ of 71–85), but the deficit is not as severe as mental retardation (70 or below). This is technically a cognitive impairment.

Persons who fall into this categorization have a relatively normal expression of affect for their age, though their ability to think abstractly is rather limited. Reasoning displays a preference for concrete thinking. They are usually able to function day to day without assistance, including holding down a simple job and the basic responsibilities of maintaining a dwelling.
