Intellectual disability is a decreased ability to think and learn. It's caused by a problem with how the brain works. 
            The diagnosis is based on intelligence quotient (IQ) tests and a child's learning problems. 
            The disability can range from mild to severe. People who have intellectual disability may have a hard time with: 
            
              - Learning, especially complex tasks. 
 
              - Language. 
 
              - Self-care (in cases of severe intellectual disability).
