Is Autism a Mental Illness or a Developmental Disorder?

June 9, 2025

Autism is not a mental illness, it is a developmental disorder.



Specifically, autism spectrum disorder (ASD) is a neurological condition that affects how a person communicates, interacts socially, and processes information. It typically appears in early childhood and lasts throughout life.

While mental illnesses like anxiety or depression can co-occur with autism, they are not the same thing. Mental illnesses often develop later in life and may come and go. Autism, on the other hand, is present from early development and influences how a person experiences the world.


Understanding this difference is important. Children with autism don’t need to be “fixed”—they need support that honors their unique strengths and challenges. That’s where ABA therapy comes in.


At Divine Steps ABA, we offer personalized, compassionate ABA therapy in Maryland, Virginia, and North Carolina to help children with autism build skills, gain confidence, and reach their full potential.
