Can autism be diagnosed before age 2?

Parents often ask whether autism can be diagnosed before age 2. The answer is yes, early signs of autism can often be identified in toddlers as young as 18 months, and in some cases even earlier. Key indicators may include limited eye contact, delayed speech or babbling, reduced response to name, and less interest in social play or imitation.

While every child develops at their own pace, recognizing these early signs is crucial. A formal diagnosis typically involves developmental screenings and evaluations by specialists who assess communication, behavior, and social interaction. Early detection matters because it opens the door to early intervention, which research shows can significantly improve long-term outcomes in language, social skills, and independence.

Families should not wait until preschool years if concerns arise. Seeking guidance early allows children to access therapies that build foundational skills during critical developmental stages.
