What age is autism usually diagnosed? Autism Spectrum Disorder (ASD) can be reliably diagnosed by age 2, but the average age of diagnosis in the U.S. is closer to 4 or 5 years old.
Early vs. Average Diagnosis
Specialists can identify autism signs as early as 18 to 24 months, when social and communication delays become clear. However, many children receive a formal diagnosis later due to symptom variability and access to screening.
The CDC reports the average diagnosis age is about 4 years, with boys often diagnosed slightly earlier than girls.
Why Early Diagnosis Matters
Early diagnosis allows for early intervention like Applied Behavior Analysis (ABA) therapy, which improves language, social skills, and behavior, leading to better outcomes.
