What is an intellectual disability1?
The person who has an intellectual disability has significant intellectual functioning limitations (reasoning, planning, problem resolution, abstract thought, understanding complex ideas, learning by experience, memorization, attention).
This person also has significant adaptive behaviour limitations, that is the whole conceptual, social and practical skills learned by the person so that they can function on a daily basis.
Intellectual disability appears during the development period and implies deficits both on the intellectual and the ability to adapt in daily life.
To decide on an intellectual disability, three criteria must be present :
- intellectual deficit
- adaptative skills deficit
- and difficulty starting during the development period.
