What is borderline intellectual functioning?

Borderline intellectual functioning, also called borderline mental disability, refers to a cognitive impairment of intelligence wherein a person has lower than average intelligence (generally an IQ of 70-85), but the deficit is not as severe as intellectual retardation.

Consistent scores within the 70 to 75 range are considered suggestive of borderline intellectual functioning and may indicate a mental disability.

Symptoms

People with borderline intellectual functioning typically have difficulties in learning, reasoning, planning, abstract thinking and judgement etc.

Causes

Lower than average intellectual functioning can result from birth injury, infections, genetics, fetal alcohol syndrome, or environmental exposure to toxins such as lead.

It is recommended that multiple tests be applied to confirm a diagnosis.
