If you have a child or a student who has been diagnosed with ADHD, it may feel like you finally have an answer to a big concern that you’ve been wrestling with.
But you may not have the answer you need most.
You know what that child has been diagnosed with. But do you know why homework takes hours? Why they forget directions almost as soon as they’re given? Why they can explain an idea out loud but can’t seem to get it onto paper? Why they lose their place while reading or blurt out answers before thinking? And do you know how to help?
An ADHD diagnosis doesn’t answer those questions.
That doesn’t mean the diagnosis is wrong. It doesn’t mean ADHD isn’t real. And it certainly doesn’t mean that medication, behavioral therapy, or school accommodations aren’t valuable. For many children and families, they are life-changing.
But in order to understand how a child learns—and how we can help them learn more successfully—we have to look beyond the diagnosis itself.
It Became Personal
This isn’t just a professional issue for me. It’s a personal one.
When my middle son was in the tenth grade, I sat in a parent-teacher conference where several of his teachers strongly encouraged me to have him evaluated for ADHD.
They weren’t wrong.
He was bright—very bright—but school was harder for him than it should have been. He struggled to stay organized, missed details, and had difficulty with many of the day-to-day demands of school that seemed to come more effortlessly to other students.
Looking back, I probably should have pursued an evaluation much earlier.
I remember one of his third-grade teachers—a wonderful teacher who genuinely loved him despite his endless energy—telling me with a smile, “He’s fine as long as I sit on him.” Not literally, of course. What she meant was that he did well when she stayed close, redirected him frequently, and kept him engaged.
At the time, I focused mostly on all the things she appreciated about him – which reflected my own experience with this unique young man – and my gratitude for her work with him. I didn’t really raise a concern for me.
I had three boys. They were all active. I assumed this was simply part of raising energetic boys.
By high school, though, it was clear that something more was going on.
When the ADHD evaluation was recommended, it felt like there were only two questions to answer:
Should he take medication?
Or shouldn’t he?
Those were important questions, and medication helps many children.
But looking back, I realize there was another question no one was asking.
How does his brain actually learn?
The diagnosis could tell me that he met the criteria for ADHD.
It couldn’t tell me whether his biggest challenges involved attention, working memory, inhibitory control, processing speed, cognitive flexibility—or some combination of those skills.
It didn’t explain why certain tasks were so difficult for him while others came easily.
Most importantly, it didn’t tell me which cognitive skills were making school harder than it needed to be—or which of those skills could be strengthened.
That’s the conversation I wish we’d been having.
And today, millions of parents are asking many of those same questions.
ADHD Is Increasing
Today, more than one in nine American children has been diagnosed with ADHD. According to the CDC, approximately 7 million children ages 3 to 17 have received an ADHD diagnosis—about 11.4% of all children in that age group. That represents an increase of roughly one million diagnoses in just six years.[i]
Whether the increase reflects greater awareness, improved diagnosis, changes in diagnostic practices, or a true increase in prevalence, millions of families are looking for ways to help their children succeed.
What a Diagnosis Tells Us—and What It Doesn’t
An ADHD diagnosis serves an important purpose.
It identifies a pattern of behaviors that can qualify a child for evidence-based treatments, school accommodations, and support services. It gives parents, teachers, and healthcare providers a common language for discussing a child’s challenges.
But ADHD is a diagnosis, not a learning profile.
It describes a pattern of behaviors.[ii]
It doesn’t explain the underlying cognitive processes that may be making learning difficult.
Imagine two children who have both been diagnosed with ADHD.
One struggles primarily to sustain attention.
Another pays attention reasonably well but has weak working memory and forgets instructions almost immediately.
A third processes information more slowly than classmates.
A fourth has difficulty with inhibitory control and acts before thinking.
All four children may meet the diagnostic criteria for ADHD.
Yet they don’t learn in the same way, and they won’t necessarily benefit from the same supports.
Thus, the answer posed by the title of this article is that it isn’t ADHD or something else. It’s ADHD and a unique pattern of cognitive strengths and weaknesses that determine how they learn. If we want to help children succeed, we have to understand both.
The Behaviors May Look the Same
Many of the behaviors commonly associated with ADHD can arise from different underlying cognitive skills, especially executive functions[iii] (working memory, inhibitory control and cognitive flexibility).
| What We See | Possible Cognitive Skills Involved |
| Doesn’t seem to listen | Sustained attention, working memory |
| Forgets multi-step directions | Working memory, sequential processing |
| Makes careless mistakes | Sustained attention, inhibitory control |
| Rushes through assignments | Inhibitory control, processing speed |
| Struggles to finish work | Sustained attention, processing speed, cognitive flexibility |
| Interrupts others | Inhibitory control |
| Has trouble shifting between activities | Cognitive flexibility |
| Takes much longer than expected to complete work | Processing speed, working memory |
Notice something important.
These behaviors don’t point to just one cognitive skill.
Nor are these skills independent. Working memory depends on attention. Inhibitory control supports sustained attention. Processing speed influences how efficiently information can be held in working memory. Learning depends on these systems working together.
That’s why two children with the same diagnosis can have very different learning needs.
Behavior Is What We See. Cognitive Skills Help Explain Why.
ADHD is diagnosed based on observable behaviors.
Learning happens through invisible cognitive processes.
A cognitive assessment helps us understand why those observable behaviors may be happening.
That’s an important distinction because once we understand the cognitive skills involved, we can choose interventions that address those specific areas of need.
Rather than asking only, “Does this child have ADHD?” we can also ask:
- Which cognitive skills are supporting learning?
- Which skills are making learning more difficult?
- Which skills could be strengthened?
Those questions move us from labeling to understanding.
For example, a common accommodation for children diagnosed with ADHD is extra time on tests. But this may or may not be helpful, depending on underlying cognitive skills such as processing speed. If a child with ADHD also has slower processing speed, then extra time makes sense. But it may not be helpful and maybe even counterproductive for a child with processing speed that is much quicker and who tends to rush, regardless of the time available.
A child whose working memory is weak may benefit from being given a list of steps to follow to solve a certain type of math problem. Providing such a list to a child whose working memory is strong simply encourages them to wait for someone else to provide direction rather than building independence and a sense of self-efficacy.
Cognitive Skills Can Be Developed
Perhaps the most encouraging discovery from modern neuroscience is that many cognitive skills are not fixed. [iv]
Attention can become stronger.
Working memory can improve.
Inhibitory control can develop.
Processing can become more efficient.
Cognitive flexibility can increase.
The list of cognitive skills doesn’t end there, but these are the ones that are often associated with an ADHD diagnosis.
That doesn’t mean cognitive training cures ADHD.
But strengthening the cognitive skills that underlie learning can make other supports even more effective by helping children process information more efficiently, stay organized, regulate their behavior, and become more independent learners.[v]
Today, my middle son, the one whose third-grade teacher had to “sit on him,” is a high-school English teacher. He is extremely well organized and channels his energy into his passion for helping his students learn to love reading and the magic of language. He is also a poet. Unfortunately, comprehensive integrated cognitive training (CICT®) wasn’t something I knew about back when it would have made things much easier for him. Today we know that many cognitive skills can be strengthened in a matter of months. While that doesn’t change an ADHD diagnosis, it can make learning easier, increase independence, and help children experience greater success in school and beyond.
Looking Beyond the Label
An ADHD diagnosis may explain that a child is struggling.
A cognitive assessment helps explain how they are struggling.
That distinction matters.
Because when we understand the individual cognitive skills involved, we move beyond simply managing symptoms. We begin building the mental tools children use every day to pay attention, remember, solve problems, regulate their behavior, and learn.
Labels have an important place. They help us understand, communicate, and access services.
But labels don’t learn.
Children with stronger cognitive skills do.
