At What Age can Autism be Diagnosed?
According to the American Academy of Pediatrics (AAP), all children should undergo ASD screening between 18 and 24 months of age. It is a crucial period for identifying potential signs and symptoms. Moreover, screenings should be conducted whenever concerns arise regarding social interactions, language development, or other developmental milestones. Timely screenings play a pivotal role in initiating appropriate evaluations and interventions.
To ascertain whether a child exhibits autism-related traits, several commonly used screening questionnaires are available.
The first among them is the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F).
This widely recognized questionnaire relies on parental reports concerning their child’s behavior and development in critical areas such as social interaction, communication, and play. If a child is deemed at risk for ASD based on the M-CHAT-R/F, it is recommended to pursue a follow-up evaluation.

Moving on, the second questionnaire is the Screening Tool for Autism in Toddlers and Young Children, affectionately known as STAT.
This screening tool employs play-based activities to assess a child’s social, communication, and play skills. Typically, a trained evaluator administers the STAT, which requires approximately 20-30 minutes to complete.
Next in line is the Ages and Stages Questionnaires:
Social-Emotional, Second Edition (ASQ:SE-2). This particular questionnaire evaluates a child’s social and emotional development, encompassing communication, play, and social interaction. ASQ:SE-2 can be conveniently completed by parents or other caregivers.
Lastly, we have the Communication and Symbolic Behavior Scales Developmental Profile (CSBS DP).
As a screening tool, the CSBS DP assesses a child’s communication and language skills, as well as their play and social interaction abilities. A trained evaluator administers the CSBS DP, and the process typically spans 30-45 minutes.
It is important to note that diagnosing autism involves a comprehensive evaluation conducted by a team of healthcare professionals. This team usually includes a developmental pediatrician, psychologist, speech therapist, and occupational therapist. The evaluation process entails observing the child’s behavior, conducting interviews with parents and caregivers, and administering standardized tests to assess the child’s developmental skills.
Extensive research has consistently shown that early detection and intervention yield significant improvements in outcomes for children with autism. For instance, a study published in the Journal of the American Academy of Child & Adolescent Psychiatry revealed that children who received early intensive behavioral intervention (EIBI) for autism exhibited better long-term outcomes compared to those who received intervention at a later stage.
Additionally, there is compelling evidence indicating that early detection and intervention can induce changes in the brain’s functioning. A study published in the Journal of Child Psychology and Psychiatry demonstrated that children who underwent early behavioral intervention for autism demonstrated alterations in brain activity associated with social and cognitive processing.
Conclusion
In conclusion, autism can be diagnosed at any age. However, the criticality of early detection and intervention cannot be overstated. By adhering to the recommended screening guidelines and promptly seeking professional evaluation, parents can identify potential signs of autism and embark on a journey of comprehensive support for their child’s development. Remember, early intervention lays the foundation for a brighter future for children with autism.
