Intellectual Disability
Intellectual Disability: Intellectual disability1 involves problems with general mental abilities that affect functioning in two areas:
- Intellectual functioning (such as learning, problem solving, judgement).
- Adaptive functioning (activities of daily life such as communication and independent living).
Additionally, the intellectual and adaptive deficit begin early in the developmental period.
Intellectual disability affects about 1% of the population, and of those about 85% have mild intellectual disability. Males are more likely than females to be diagnosed with intellectual disability.
