The child is reluctant to speak with others and does not enjoy playing with other children. I’ve heard that such children may have autism. Could you please clarify whether intellectual disability and autism are different conditions?

Intellectual disability and autism in children are distinct conditions. In intellectual disability, a child’s cognitive development is impaired, resulting in generally low intelligence, fair social adaptability, relatively good environmental adaptability, no language impairment, and a desire to communicate with others—yet the condition is typically irreversible. In contrast, individuals with autism primarily lack typical social interaction skills and the ability to communicate effectively with the outside world; however, their IQ is not necessarily low. Some individuals with autism may even demonstrate exceptional abilities—“savant” talents—in specific domains. One shared feature of intellectual disability and autism is relatively low emotional intelligence, leading to difficulties in normal communication with others.
