Intellectual disability begins in childhood. People with intellectual disability have limits in their mental functioning seen in below-average intelligence (IQ) tests and in their ability to communicate, socialize, and take care of their everyday needs. The degree of disability can vary from person to person. It can be categorized as mild, moderate, severe, or profound.

Some causes of intellectual disability can be prevented with proper medical care. Children diagnosed with an intellectual disability are most successful when they get help early in life. If you suspect that your child may have an intellectual disability, contact your doctor.
