Can a Child Have Both ADHD and Autism?

In this article, you’ll learn:

• What is AuDHD
• What a thorough evaluation should include
• Support strategies for AuDHD
• How to advocate effectively for your child's diagnosis and care

If you’re reading this, you’ve probably already done a lot of searching about ADHD and autism. Maybe your child has a diagnosis that explains some things but not everything. Perhaps you’ve discussed neurodiversity. You’ve tried strategies that work sometimes and fail other times. You’ve probably left appointments with pieces of an answer and a plan that never quite adds up to the full picture. What you know for sure is that something is still being missed.

Sometimes that something is AuDHD.

What is AuDHD?

AuDH is AuDHD is the experience of having both Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD). Part of the difficulty in identifying AuDHD is that it is not simply the sum of both conditions. AuDHD is what happens when ADHD and autism interact and create a separate experience that is different from the sum of its parts.

According to the American Psychiatric Association, some of the most common experiences for children with AuDHD include:

Being easily overwhelmed but feeling unable to slow down and recharge, struggling between a preference for routines and boredom from sameness, craving social connection while finding it hard to navigate social situations.

While ADHD and autism are different conditions, they involve some of the same underlying brain systems. Researchers believe that ADHD and autism may be different patterns within the overlapping networks that help the brain regulate:

• Executive functioning: Skills like organization, working memory, and starting tasks.

• Attention regulation: Difficulty shifting attention or sustaining focus.

• Sensory processing: Sensitivity to sound, textures, or crowded environments.

• Emotional regulation: Managing frustration, disappointment, and transitions.

AuDHD is a community-coined term, not a formal diagnosis. Clinicians will diagnose your child with ADHD and autism separately but many families, clinicians, and individuals have embraced the term AuDHD.

What a thorough evaluation should include

One thing that surprises many families: the diagnosis, evaluation, and treatment process isn't as simple as following a flowchart. There isn't a standard sequence of "if this, then that." The focus instead should be on your individual child, and what’s actually making their daily life hard right now. For most children, this means looking further and going deeper, rather than stopping at the first explanation that fits. A whole-child assessment addresses more than symptoms, it uncovers underlying causes that are often missed.

A quality evaluation for AuDHD should include:

• Input from multiple people across multiple settings. Both ADHD and autism require symptoms to be present in more than one environment. A clinician working only from a parent interview is missing a significant part of the picture. Teachers, coaches, and other adults in your child's life should be part of the process. The APA notes that input from both parents and teachers is critical to early and accurate identification and that without it, children with both conditions are frequently missed.

• Separate assessment tools for each condition. An ADHD evaluation and an autism evaluation use different tools. If your child has been assessed for one, that doesn't mean the other has been examined. A thorough evaluation uses validated measures for both including structured observation and standardized rating scales completed by caregivers and teachers across different settings.

• A full developmental history. When symptoms first appeared, how they've changed over time, what your child's early social and language development looked like, and what your family history includes: all of this matters. It's the difference between a clinician who understands your child and one who sees a snapshot.

• Attention to what else might be going on. Anxiety, depression, and sensory processing differences frequently travel alongside both ADHD and autism. A good evaluation doesn't stop at identifying the primary conditions. It looks at the full picture of what's affecting your child's daily life including evaluations with behavioral therapists, occupation therapists, speech and language therapists, and other specialists.

If your child already has one diagnosis and you're not sure whether the other has ever been formally evaluated, you can ask directly: has this been assessed, and what tools were used? You deserve a clear answer.

Which support strategies work best for AuDHD

When ADHD and autism occur together as AuDHD, support strategies often need to address multiple areas of development at once. Effective care may include combinations of:

• Behavioral or therapeutic support
  Helping children develop emotional regulation, social understanding, and coping strategies.

• Executive functioning support
  Building skills related to planning, organization, and task completion.

• Speech-language or communication support
  Addressing social communication differences when needed.

• Environmental adjustments
  Reducing sensory overload or providing structured routines.

• Medication management
  Sometimes used to support attention or emotional regulation when appropriate.

When medication isn't tolerated or isn't the right fit for a family, occupational therapy (OT) can be a primary path to helping children regulate their emotions and build executive functioning skills. It can also inform IEP or 504 accommodations in ways that are far more specific than a general ADHD diagnosis alone would allow.

Because every child’s profile is different, treatment plans often work best when they focus on the child’s specific strengths and challenges rather than a single diagnosis.

Why one diagnosis often comes first

It's common for children with AuDHD to receive one diagnosis years before the other. ADHD traits often appear earlier, especially in structured settings where activity and attention level are easy to observe, like the classroom. If an evaluation follows, ADHD may be identified and because that explains some of what parents and teachers are seeing and the search sometimes stops there.

Autism traits may be slower to surface, especially in children with average or above-average intelligence. Many children develop ways of compensating such as masking or camouflaging by watching other children carefully and scripting conversations and actions. Children with less obvious symptoms, particularly girls, often fly under the radar entirely.

The reverse happens too. Autism is caught early. ADHD is assumed to be a part of it and the difficulties never get their own evaluation or their own treatment.

Neither sequence is unusual. But as ADDitude Magazine points out, if a child with autism is diagnosed only with ADHD, the treatment plan will miss core issues around social communication and inflexibility. Unaddressed ADHD can also undermine the autism therapies your child is already receiving, because distractibility gets in the way of the very skills those therapies are trying to build.

It's also worth remembering that children change significantly and quickly with age. This is why evaluation isn't a one-time event. Annual evaluations, alongside regular treatment plan reviews, mean that new patterns can be recognized as they emerge, rather than being missed because they weren't present at an earlier stage.

How to advocate for your child

You are the expert on your child. Cedars-Sinai puts it plainly: parents spend the most time with their children and know them very well. Trust your instincts if something feels incomplete.

You don't need certainty before you reach out. You need enough concern to ask the question clearly.

A few things that make a real difference when you're navigating this:

• Write things down before appointments. What you're seeing in concrete terms, what specific behaviors, how often, in what settings, what makes it better or worse. Include frequency and pattern where you can. Generalities are harder to work with than examples. Gather previous evaluations if they exist.

• Loop in the other adults in your child’s life. Teachers, coaches, camp counselors. Teachers can complete behavioral rating scales that are part of a formal evaluation. They're also often the first to notice patterns you don't see at home. If your child already has an IEP or 504, bring that documentation to every appointment, it tells a story about how your child functions in a structured environment over time. Children often present very differently across settings, and the differences matter clinically.

• Ask specifically whether both conditions have been assessed. Don't assume that because your child has been evaluated, everything has been looked at. Ask directly. If the answer is vague, that's useful information too.

• Follow through on referrals. If your pediatrician refers you to a specialist, follow up. If the waitlist is long, ask about alternatives. The system is strained; there simply aren’t enough specialists across the U.S., which means families often have to be persistent to be seen.

• Know that an evaluation is not a commitment. Asking for a comprehensive assessment doesn't lock you into a diagnosis, a treatment plan, or years of appointments. It gives you better information. What you do with that information is always your decision.

How Blackbird Health can help

At Blackbird Health, we don't start evaluations with an assumption about what we're going to find. Our whole-child model is built around the understanding that many children have more than one thing going on and that identifying all of it is what makes care actually work.

When both ADHD and autism may be present, we look at how they're interacting for your specific child. That means input from multiple sources, assessment tools for both conditions, attention to co-occurring factors like anxiety, sensory differences, and family history, and a treatment plan that addresses the full picture.

Care at Blackbird Health is built around a team, not a single provider. A nurse practitioner leads as the primary clinician and the keeper of the overall treatment plan — but they work closely with therapists, occupational therapists, speech and language specialists, and, when needed, school guidance counselors. All clinicians share access to the same treatment plan, which means when an OT evaluation happens, those findings are already integrated into the next medical visit. When a therapist notices something new, the NP can hear about it quickly. That kind of real-time communication across disciplines isn't available everywhere, and it changes what's possible in terms of care.

Families can expect regular treatment plan reviews—at minimum quarterly, and more frequently when medication is new or being adjusted. Starting a medication typically means check-ins every two weeks for the first two months. For children on a controlled substance, monthly visits are common even when things are stable. These aren't just administrative touch points—they're how the team stays current and responds to a child as they change.

We also stay with you after diagnosis. Therapy, medication management when appropriate, school advocacy, and coordination with your child's other providers are all part of how we work.

Families in Pennsylvania, Virginia, and New Jersey can typically access evaluations at Blackbird Health within 2–6 weeks. To get started or talk through your options, call (484) 202-0751, email info@blackbirdhealth.com, or click here to begin registration.

If you're a parent who has been carrying a diagnosis that felt like part of the answer, it's worth asking whether the rest of the picture has been examined.
