Autism Vs. ADHD: What Parents Should Know

Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are two conditions that affect how the brain works and develops. Areas of the brain that control thinking, focus, and emotions may work differently in children with these diagnoses. 

ASD and ADHD are often identified in childhood and can look similar at first, which is why families sometimes feel unsure about what’s really going on. Understanding how they overlap (and how they differ) can help parents, caregivers, and teachers give children the right type of support.

Are ADHD and autism linked?

According to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the guide healthcare providers use to diagnose behavioral and developmental conditions, both autism spectrum disorder and ADHD are recognized neurodevelopmental conditions. This means they begin in early childhood and affect how a child learns, behaves, and interacts with the world.

While they are separate diagnoses, many children show overlapping traits between ADHD and autism, which can sometimes make it harder to tell them apart early on. Autism spectrum disorder affects how a child communicates, interacts socially, and processes sensory information. Common characteristics include:

• Differences in social interaction and communication
• Restricted or repetitive behaviors and interests
• Sensory sensitivities or seeking intense sensory input
• Difficulty with changes in routine or transitions

ADHD affects attention, impulse control, and activity level. In children, it often shows up as:

• Difficulty focusing or staying on task
• Seeming “always on the go” or very active
• Impulsivity, such as acting without thinking or interrupting
• Trouble organizing tasks or following multi-step directions

ADHD vs. autism spectrum disorder

Some children may be diagnosed with both ASD and ADHD, while others may show overlapping traits without meeting criteria for both. Studies show that 30% to 50% of individuals with autism display symptoms of ADHD, especially at younger ages. On the other hand, up to two-thirds of individuals with ADHD show features of autism. In clinical settings, even more children with autism may show ADHD-related behaviors, with some studies reporting rates as high as 85%.¹

Attention-deficit/hyperactivity disorder (ADHD)

Attention-deficit/hyperactivity disorder affects how children pay attention, manage energy, and control impulses. Some children diagnosed with ADHD struggle to stay focused, while others may be more hyperactive or act without thinking. ADHD is often treated with medication, behavioral therapy, school accommodations, and changes to daily routines.

Autism spectrum disorder

Autism is a spectrum disorder, meaning it affects each child differently. Children diagnosed with autism may have trouble with communication, eye contact, or understanding social cues. They may repeat certain movements, prefer routines, or develop strong interests in specific topics. Autism is often supported through therapies such as applied behavior analysis (ABA) therapy, which uses the science of learning to help children build new skills using evidence-based strategies and positive reinforcement.

How are autism and ADHD similar?

Despite their differences, autism and ADHD share several traits. Both conditions can affect how children behave, interact with others, and understand the world around them.

Children with either condition may experience:

• Trouble paying attention
• Seeking or avoiding sensory experiences
• Social challenges
• Impulsive behaviors
• Difficulty staying motivated

Some children may have both ASD and ADHD. However, having a few shared symptoms doesn’t always mean a dual diagnosis. A pediatrician or specialist can help determine what’s truly going on and recommend the next steps. 

Common challenges when autism and ADHD overlap

Every child is different, but common challenges for children children diagnosed with autism who also show challenges with attention, activity level, or impulse control can include:

• Big emotions and frequent meltdowns: Overwhelm from sensory input, frustration, or changes in routine can lead to intense reactions.
• Difficulty focusing and following directions: Your child may struggle to stay with a task, remember steps, or shift attention when needed.
• Impulsivity and safety concerns: Running off, grabbing items, or acting without thinking can be more common.
• Sensory seeking or sensory avoidance: Some children crave movement, touch, or noise, while others may be sensitive to these sensations.
• Challenges with social skills: Taking turns, reading body language, or managing conversations can be hard, especially in busy environments.

How ABA therapy helps children diagnosed with ASD 

Applied behavior analysis is a gold standard, evidence-based treatment for children diagnosed with autism spectrum disorder. At Action Behavior Centers, we focus on helping children build meaningful skills and reduce behaviors that make learning and daily life harder.

Some children diagnosed with autism may also have attention, activity level, or impulse-related challenges, like ADHD. While ABA therapy is designed to address needs related to autism, it can also support these areas when they impact a child’s ability to learn, communicate, and participate in everyday routines. These skills are always taught within the context of your child’s autism-related goals.

Building focus and task completion skills

Our clinicians help children build attention and follow-through by breaking skills into small, achievable steps and using positive reinforcement. Over time, children may learn to:

• Stay engaged with tasks for longer periods
• Follow directions and daily routines
• Complete activities like schoolwork or self-care with more independence

Supporting functional communication

When a child has difficulty expressing their needs, it can show up as frustration or unsafe behaviors. ABA therapy helps children build safer, more effective ways to communicate by:

• Teaching functional communication to express wants and needs
• Introducing strategies like asking for a break or requesting help
• Reducing behaviors such as hitting, yelling, or running away by addressing the underlying need

Improving daily living and independence

ABA therapy also supports everyday routines that help children become more independent. This may include:

• Morning and bedtime routines
• Dressing, toileting, and hygiene
• Mealtime participation
• Transitioning between activities

Every child’s treatment is individualized based on their unique needs. Our goal is to help children build skills that support their growth, independence, and participation in daily life.

How to support autistic children at home

You can’t change a diagnosis, but you can shape your child’s environment in ways that help them feel more supported, calm, and successful. Some children diagnosed with autism may also have challenges with attention, activity level, or impulse control. These strategies can help support your child’s daily routines and make learning more manageable.

Here are practical strategies you can start using today:

1. Create predictable routines

Children diagnosed with autism often do best when they know what to expect. Predictable routines can reduce stress and help your child move through the day with more confidence.

• Use simple routines for mornings, after school, and bedtime
• Keep steps short and consistent
• Give transition warnings like, “5 more minutes, then we clean up”

2. Use visual supports

Many children understand and follow visuals more easily than spoken instructions. Visual supports stay in front of your child longer than spoken directions, which can reduce confusion and repeated prompts.

• Try visual schedules with pictures or simple words
• Use visual timers so your child can see how much time is left
• Create “first-then” boards, like “First homework, then play”

3. Build in movement and sensory breaks

Some children need more movement or sensory input to stay engaged and comfortable. Planned breaks can help your child reset and return to tasks with better focus.

• Offer short movement breaks between tasks, like jumping, stretching, or walking
• Use tools like fidgets or cushions if recommended by your care team
• Create a calm space with soft items for quiet breaks

4. Give clear, simple instructions

Long or complex directions can be overwhelming. Clear instructions can reduce frustration and make it easier for your child to follow through.

• Use short, direct phrases like “Shoes on” or “Sit at the table”
• Give one step at a time when possible
• Ask your child to repeat the direction to check understanding

5. Use positive reinforcement 

Children learn best when helpful behaviors are noticed and encouraged. This helps your child understand what to do and builds motivation to keep trying.

• Praise specific actions, like “You followed directions right away”
• Offer small rewards, such as stickers, extra playtime, or a favorite activity
• Keep reinforcement immediate and consistent

6. Break tasks into smaller steps

Large tasks can feel overwhelming, especially when attention or organization is a challenge. Smaller steps help your child experience success more often and build independence over time.

• Break activities into small, manageable steps
• Let your child check off each step as they go
• Offer short breaks between steps if needed

How to support children with autism and ADHD traits at school

School can feel overwhelming for some children diagnosed with autism, especially when they also have challenges with attention, activity level, or transitions. Working closely with your child’s school team helps create a more supportive, consistent environment where they can learn and participate more fully.

Here are a few ways to support your child at school:

Work with teachers and support staff
Open, ongoing communication helps everyone stay aligned.

• Share what works well at home, including routines, motivators, and calming strategies
• Ask for regular updates on outcomes, behavior, and classroom participation
• Collaborate on consistent strategies your child can use across settings

Explore accommodations and supports
Some children benefit from extra structure or environmental adjustments.

• Preferential seating or reduced distractions
• Visual schedules or written instructions
• Movement or sensory breaks during the day
• Extra time for transitions or completing tasks

Ask about formal support plans
If your child needs additional support, you can talk with the school about formal services such as an Individualized Education Program (IEP) or a 504 plan.

These plans can outline:

• Specific learning and behavior goals
• Accommodations tailored to your child’s needs
• Services like speech, occupational therapy, or classroom support
