Introduction
The intelligence of individuals with autism is not fixed at a specific age level. Most have varying degrees of intellectual development differences, with some approaching normal intelligence or demonstrating talents in specific areas, while a minority may have co-occurring intellectual disabilities. If a child shows signs such as abnormal social communication and restricted interests, prompt medical evaluation is recommended. The core features of autism are impairments in social communication and the presence of repetitive, stereotyped behaviors.

The core features of autism are social communication difficulties and repetitive, stereotyped behaviors—not a fixed age of intellectual stagnation. Some individuals experience delays in language, logical thinking, and other developmental areas, and their intellectual performance may lag behind peers. However, through early intervention and systematic training, their cognitive abilities can progressively improve.
Individual variability is key to understanding intellectual expression in autism. Some individuals demonstrate exceptional talents in fields such as mathematics, music, or memory, with intellectual levels surpassing those of the general population. Therefore, it is inappropriate to define their intellectual potential using a single standard; personalized assessment and intervention should be based on individual characteristics.
Providing structured learning environments, focusing on targeted training for social and cognitive skills, offering consistent positive reinforcement, and incorporating the individual's interests and strengths into teaching can help gradually enhance adaptive functioning and intellectual development.
