Intellectual disability is a disability characterised by significant limitations in both intellectual functioning and in adaptive behaviour, which covers many everyday social and practical skills. This disability originates before the age of 18.

A person with an intellectual disability may have significant limitations in the skills needed to live and work in the community, including difficulties with communication, activities of daily living, social skills, safety and self direction.

Intellectual disability has certain effects on the lives of individuals.  Every person who has intellectual disability is a unique individual and as such they are going to face different challenges.
