Neuropsychological Testing for Autism Diagnosis

Learn how neuropsychologists diagnose autism and why their expertise is essential.

When parents begin to notice differences in their child’s development, it’s natural to wonder if autism could be a factor. Getting clear and accurate answers is essential—and that’s where neuropsychological testing comes in. At North Shore Pediatric Therapy, we partner with families through the Chicago Autism Testing Institute (CATI) a part of NSPT, to provide comprehensive neuropsychological evaluations that help parents understand their child’s unique strengths, challenges, and needs.

Understanding Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that affects communication, social interaction, and behavior. According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), children with ASD may experience challenges such as:

  • Difficulties with social-emotional reciprocity
  • Trouble interpreting nonverbal communication like body language and facial expressions
  • Challenges forming or maintaining relationships

In addition, many children with autism show repetitive behaviors, strong interests, or a need for routines. Because autism presents differently in every child, accurate diagnosis requires expert evaluation and input from both professionals and family members.

The Importance of Screening and Early Identification

Screening is often the first step toward recognizing autism. Pediatricians and healthcare providers use screening tools during well-child visits—often at 18 and 24 months—to look for signs of developmental differences. These tools are not diagnostic but help determine whether a more in-depth evaluation may be needed.

If screenings or parental concerns suggest autism, a comprehensive evaluation is recommended. Early diagnosis ensures children and families can access the resources, therapies, and support systems that make a meaningful difference in a child’s growth and development.

What Does a Neuropsychologist Do?

A neuropsychologist is a specialist who studies the relationship between the brain, behavior, learning, and emotions. Unlike general psychologists, neuropsychologists take a broad, detailed look at how a child thinks, processes, and interacts.

In autism evaluations, a neuropsychologist will:

  • Conduct in-depth interviews with parents and caregivers
  • Administer standardized tests to assess memory, language, attention, problem-solving, and social skills
  • Observe how a child communicates, interacts, and adapts in different situations
  • Differentiate autism from other conditions, such as ADHD, learning disorders, or anxiety

This level of expertise is critical, as many developmental challenges overlap, and a clear understanding helps create the best plan of support for the child.

Why Neuropsychological Testing Matters

Because autism is a spectrum, every child’s profile looks different. Some may excel in problem-solving but need extra support in social communication. Others may thrive in structured routines but struggle with flexibility or daily living skills.

Neuropsychological testing provides a complete picture of your child’s development, including:

  • Cognitive strengths and challenges
  • Social communication abilities
  • Emotional and behavioral regulation
  • Academic readiness and learning styles
  • Daily living and adaptive skills

Rather than stopping at a diagnosis, neuropsychological testing helps families understand how autism impacts their child specifically. This information becomes a roadmap for early intervention, individualized therapies, school supports, and ongoing growth.

Testimonials

Success looks different for every child... But we bet we have a story that matches your child's needs. Like James, who started with us as non-speaking and lacking the ability to initiate and maintain social interactions. Today, he can speak complete sentences, clearly state his needs, and navigate social interactions with his friends!

Our infant daughter was in physical therapy with Anna Zahn for about five months.  Anna was consistent, patient, and wonderful with our daughter.  Anna was also clear in her communications with us as parents which helped us understand our daughter's progress and needs, as well as how we could help our daughter at home.  While we are proud that our daughter graduated PT, we will miss Anna's warmth and kindness.

I love this place! Chista is an amazing person, so sweet and kind and very professional in her work. All staff are very kind with children. I feel happy to find this place for my daughter. Thank you!!!

Maria Di Rita

I cannot say enough nice things about the staff! My son worked with Khadija as his ABA therapist and is finishing up this week with his OT, Sabrina. They were really instrumental in helping us navigate a new diagnosis. Both were so easy to approach with questions. From Leeann at the front desk to the RBTs (Alex, Rabbia, Molly, and many others), we always felt so welcomed. It seems like the staff genuinely enjoy their jobs, consistently offering feedback and suggestions on how to help my son.
