What is intellectual disability?
Intellectual disability is a brain problem that results in lower than normal intelligence. It can happen as your baby's brain develops in your womb.

Most children start to show symptoms in preschool—they are usually slower to speak and use sentences
Treatment includes different kinds of therapy and special education
To lower the chance of your baby having intellectual disability:
Take folate (folic acid) before conception and in early pregnancy
Avoid alcohol during pregnancy
Get good health care while you're pregnant
