What is autism?

Autism spectrum disorder (ASD) is a lifelong neurological and developmental condition that shapes how people communicate, learn, and interact with the world.

While autism is a disability that can involve significant social or behavioral challenges, it’s also increasingly understood as a natural and valuable variation in human neurology. From this perspective, autism represents a different way of thinking and experiencing life, rather than a condition that needs to be “fixed.”

Clinically, autism is described through two main areas of difference: social communication and interaction, and patterns of behavior that may be repetitive or highly focused. In everyday life, this can look like unique ways of engaging in conversation, a strong preference for routines, or intense interests in specific topics.

Because autism is a spectrum, every person has their own unique combination of strengths, abilities, and support needs. These can change over time. To help guide support, clinicians sometimes describe autism using severity levels (1, 2, and 3), which describes how much assistance someone needs in daily life.

One of the most encouraging aspects of autism is the remarkable strengths many individuals possess. Many people on the spectrum have exceptional attention to detail, strong memory, and talents in areas such as math, science, music, art, or technology. Others are highly effective visual or auditory learners and bring creativity and fresh perspectives to the way they approach problems.

Living in a world largely designed for neurotypical people can present challenges. But with early identification of autism and supportive services—such as speech therapy, occupational therapy, and individualized interventions—many individuals on the spectrum build important skills and thrive. When we focus on strengths, and create environments that are inclusive and supportive, people with autism can lead fulfilling, independent, and self-directed lives.
