An intellectual disability is an impairment that affects a person’s ability to learn, problem-solve, make judgments, or adapt to daily circumstances. As well as having learning difficulties, someone with an intellectual disability might have a difficult time getting dressed or eating without the aid of a caretaker, for example. Some intellectual disabilities are the result of head injuries, infections, or other conditions that occurred during or after birth. Others, such as Down syndrome, are associated with genetic disorders.
