Can Autism Be Diagnosed Before Age 2?

July 27, 2025

Yes, autism can often be diagnosed before age 2, although it can be challenging. Early signs of autism may appear as early as 6 months, and more obvious signs typically emerge by 12 to 18 months. While a formal diagnosis is generally made by a healthcare professional, some children may show early developmental differences in communication, social interaction, and behavior that can suggest autism.

Healthcare providers may look for signs like limited eye contact, delayed speech, repetitive behaviors, or difficulty with social engagement. Early intervention is crucial for helping children with autism develop vital skills. The earlier autism is diagnosed, the sooner therapy can begin, which can significantly improve outcomes.


At Little Rays ABA, we specialize in early intervention in Florida through personalized ABA therapy that focuses on communication, social skills, and behavior. Early therapy helps children develop the skills they need to succeed in life.
