Autism Spectrum Disorder
What Is Autism Spectrum Disorder?
Autism spectrum disorder (ASD) is a developmental condition affecting social skills, communication and behaviors. ASD symptoms, ability and support needs can vary from minor to severe. The autism spectrum refers to the full range of these symptoms and needs. For example, some children with autism may thrive in school and community settings. Others might require assistance with everyday tasks, such as attending class or getting dressed.
About 1 in 31 8-year-old children documented in a Centers for Disease Control and Prevention (CDC) program have been identified with ASD. The program used 2022 data from 16 sites across the country. ASD occurs across all racial and ethnic groups and is 3.4 times more common among boys than among girls.

What Are the Signs of Autism?
ASD affects each child differently, and signs may appear as early as infancy.
Here are some common characteristics:
- Appears to be in their "own world" or disengaged from others around them.
- Delayed speech or language development
- Intense focus on specific topics, routines or activities
- Limited eye contact and difficulty with social interactions
- Minimal babbling during infancy
- Reduced use of gestures such as pointing or waving
- Repetitive behaviors or speech patterns
- Sensory sensitivities, such as strong reactions to sounds, lights and tastes
- Sensory-seeking behaviors, such as a strong interest in visual inspection and exploring textures
What Causes Autism Spectrum Disorder?
There is no single known cause of ASD. Experts believe it develops from a combination of genetic and environmental influences:
- Genetics: About 70% of ASD cases have a suspected genetic link, though it is not always identifiable.
- Environmental factors: Some environmental factors may increase risk, but currently, they are not fully understood.
How Is Autism Spectrum Disorder Diagnosed?
There is no blood test or brain scan that can confirm autism. If your child has ASD, they will be diagnosed based on their behavior and developmental history.
Diagnostic tools include:
- ADOS (Autism Diagnostic Observation Schedule), a play-based, standardized assessment
- Clinical observations by developmental pediatricians, psychologists or other trained providers
- Parent and teacher input through developmental questionnaires and interviews
Diagnosis typically involves a team-based approach.
How Is Autism Treated?
There is no one standard treatment for ASD. We personalize your child’s treatment plan and may include a mix of therapies, including the following:
- Applied behavior analysis (ABA) teaches new skills and behaviors using positive reinforcement.
- Occupational therapy helps with motor coordination, sensory issues and daily living skills.
- Social skills groups teach children how to interact with peers in structured settings.
- Speech therapy supports verbal and nonverbal communication.
The Role of Medications
Your doctor may prescribe medicine to help manage ASD-related conditions such as ADHD, anxiety, sleep problems or aggression. However, these medications do not treat ASD itself.
Parental Training
Parent training is a key part of ASD treatment and is essential to your child’s care plan at Lurie Children’s. It equips caregivers with practical tools to manage disruptive behaviors, build routines and support their child’s development at home.
At Lurie Children’s, parents learn how to use special techniques consistently across different settings — home, school and the community. This helps children carry the skills they learn during therapy sessions into everyday life.
Research over the last decade shows that parental training improves a child’s behavior and skill development while reducing caregiver stress. The training works by helping parents feel more confident and competent in managing their child’s behavioral challenges.
Communication Tools
Some people with ASD use augmentative and alternative communication (AAC) tools if they are nonspeaking or have limited speech. These tools can help your child communicate, either by assisting them with their verbal skills or allowing them to express themselves without actually speaking.
Here are some examples:
- Apps that help with sentence formation and comprehension
- Picture boards or visual schedules
- Tablet-based systems that vocalize messages
AAC devices can help your child participate more fully in daily life.
What Are the Long-Term Effects of Autism Spectrum Disorder?
ASD is generally a lifelong condition. However, with early support and consistent therapy, many people build skills they need to meet the challenges they face.
Long-term outcomes vary widely. Some people live independently, go to college and build fulfilling relationships. Others may require lifelong support, depending on their needs and access to resources.
Are There Any Strengths Associated With ASD?
Many people with ASD excel in certain areas, including:
- Strong memory and attention to detail
- Advanced visual or spatial reasoning
- Keen sensitivity to environmental changes
These qualities are part of the broader concept of neurodiversity, which values and respects different ways of thinking and experiencing the world.
The Truth About Autism
Misunderstandings about autism abound. Here’s the truth:
- Autism is not the same as an intellectual disability. Many people on the autism spectrum have typical or high intelligence.
- People with ASD aren’t necessarily antisocial. Many people on the autism spectrum seek out and enjoy social interaction. However, they may struggle with the nuances of communication.
- Vaccines do not cause autism. There’s no legitimate research to suggest a connection.
