Which of the following statements regarding autism is correct?

The statement that most cases of autism are diagnosed by age 3 is correct. Research and clinical observations indicate that signs of autism typically emerge in early childhood, often before the age of 3. Early identification is crucial because it allows for timely intervention, which can significantly improve outcomes for children on the autism spectrum.

While there is a range of development in kids diagnosed with autism, identifying the condition early means that strategies and supports can be provided to enhance communication skills, social interactions, and behavior. This emphasis on early diagnosis is part of efforts to promote awareness and improve developmental support for children with autism.

The other statements are not accurate. Autism is not always diagnosed during adolescence as many individuals are diagnosed in early childhood. Furthermore, while it’s true that some individuals with autism may have above-average intelligence, this is not universally applicable, as autism can occur across a wide range of cognitive abilities. Additionally, many children with autism benefit greatly from and often require special education services tailored to their unique learning needs.
