ADHD: A Disorder of Regulation?
Updated: Oct 8
What if ADHD isn't really about a lack of attention?
By Kathryn Spence | Accredited BACP Psychotherapeutic Counsellor, Accredited BABCP CBT Therapist, EMDR Therapist | InnerFocus Therapy | October 2026
The name Attention Deficit Hyperactivity Disorder can make ADHD sound as though the problem is simply that someone cannot pay attention, or that they’re always hyperactive. But that doesn't quite fit the reality.
How can someone struggle to concentrate on a ten-minute email, but spend six hours completely absorbed in something they love?
How can someone be exhausted but unable to slow down?
How can someone forget to eat because they are so absorbed in something, yet become intensely aware of the smallest sound, texture or sensation?
How can someone struggle to start something for days, then suddenly complete it in a burst of energy when a deadline arrives?
And how can the same person experience happiness, excitement, love, music, nature or creativity with an intensity that can feel extraordinary?
Perhaps ADHD isn't simply about having too little attention. Perhaps, at least for some people, it is partly about regulation — regulating attention, energy, emotion, motivation, impulses, sensory information and other aspects of our internal state.
This doesn't mean ADHD has officially been redefined as a "regulation disorder". It hasn't. But regulation is becoming an increasingly useful way of thinking about ADHD. And there is an important difference between a deficit and a difficulty regulating something.
A deficit can sound as though something is missing.
A regulation difficulty suggests that the capacity may be there — but that it isn't always available at the right time, in the right amount, or under conscious control.
That distinction changes the way we can look at ADHD...
Emotional Regulation
Feeling deeply
People with ADHD can experience emotions intensely.
Frustration can become enormous.
A small criticism can hurt deeply.
Excitement can feel almost impossible to contain.
Anger can arrive quickly.
Sadness can feel physically painful.
But emotional intensity isn't inherently a bad thing. It can also mean experiencing joy, love, humour, excitement, compassion and beauty intensely.
Music can bring tears.
Falling in love can feel completely absorbing.
A friend's happiness can make you genuinely happy.
A beautiful landscape can stop you in your tracks.
The difficulty isn't necessarily feeling too much. It can be having difficulty controlling how quickly an emotion arrives, how intensely it is experienced, how long it lasts, or how quickly you can return to your usual state afterwards. The aim isn't necessarily to feel less. It is to have more control over the volume.
Attentional Regulation
Attention that follows interest
One of the strangest things about ADHD is being told that you "can't concentrate" when you know perfectly well that you can. You can concentrate for hours. Just not necessarily on the thing you're supposed to be concentrating on.
A boring form can feel almost physically impossible.
A fascinating subject can become completely absorbing.
A mundane job can take forever.
A problem you're passionate about can keep you awake until 3am.
This is why the word hyperfocus has become so closely associated with ADHD, although it isn't a formal diagnostic term. The issue may be less about having no attention and more about having difficulty directing and shifting attention deliberately.
Attention can be strongly influenced by:
interest; novelty; challenge; urgency; reward; emotional significance.
And there is a positive side... When something genuinely captures the mind, the resulting concentration can be extraordinary.
Curiosity can become deep expertise.
Interest can become mastery.
Absorption can become creativity.
The challenge is being able to access that attention when you choose, rather than only when the brain finds the task compelling enough.
Impulse Regulation
Acting quickly
ADHD can make the gap between thinking something and doing something unusually short.
You might interrupt because the thought feels as though it will disappear if you don't say it.
You might answer before someone has finished asking the question.
You might buy something on impulse.
You might say exactly what you're thinking.
You might make a spontaneous decision and only consider the consequences afterwards.
But spontaneity isn't inherently bad. It can also mean:
being adventurous; taking opportunities; trying things other people wouldn't; responding quickly; being playful; being willing to take a chance.
The problem isn't necessarily having impulses. It is having enough control over them to decide:
"Is this something I want to act on right now?"
Energy and Arousal Regulation
Tired and wired
Some people with ADHD experience their energy as something that is difficult to regulate. There can be periods of:
"I cannot get myself going." followed by "I cannot stop myself going."
You might be exhausted but restless.
You might desperately need sleep but find your brain and body unwilling to settle.
You might spend hours unable to start something, followed by a burst of extraordinary productivity.
You might need movement, music, stimulation or activity to feel properly awake.
And then, sometimes, you crash.
Researchers have explored this in terms of arousal and state regulation — essentially, whether the brain and body are at the right level of activation for what is being asked of them. This may help explain why the same person can appear sluggish in one situation and full of energy in another.
And again, there can be a positive side. When the right thing captures your attention, there can be enormous energy, enthusiasm and persistence. The problem isn't necessarily having too much or too little energy. It may be getting the engine into the right gear.
Cognitive and Executive Regulation
A busy, flexible mind
ADHD can make organising thoughts and actions difficult.
You may know what you need to do but not know where to begin.
You may start one thing, remember another, get distracted by a third and suddenly find yourself researching something completely unrelated.
You may struggle to: organise; prioritise; plan; remember several steps; finish what you started; switch between tasks; or keep a goal in mind.
Your mind can also become crowded with thoughts.
Ideas arrive one after another.
A worry can turn into ten worries.
A passing thought can become a rabbit hole.
But a busy mind isn't necessarily an empty or incapable mind. It can also be curious, associative, imaginative and quick to make connections.
You may notice relationships between ideas that other people don't immediately see.
You may approach problems from unusual directions.
You may think laterally rather than linearly.
The challenge is not necessarily to make the mind less active. It is to develop ways of steering it.
Motivational Regulation
When wanting to isn't enough
One of the most misunderstood parts of ADHD is motivation.
You can genuinely want to do something and still be unable to start.
You can care deeply about the outcome.
You can know exactly what will happen if you don't do it.
And still sit there unable to make yourself begin.
This can be incredibly confusing — both to the person experiencing it and to the people around them. Why would someone who cares about something so much struggle to do it? Because motivation isn't necessarily experienced as a simple decision. Tasks involving novelty, interest, challenge, immediate reward, urgency or emotional significance can suddenly become much easier to engage with. This is one reason deadlines can be strangely powerful.
At 2pm, tomorrow's deadline may feel abstract.
At 11pm, it is suddenly very real.
And suddenly you can work.
That doesn't necessarily mean you were lazy at 2pm.
It may mean that urgency changed your motivational state.
When interest switches the system on:
A person might become completely absorbed in something they care about. Once the motivational system is engaged, there may be enormous enthusiasm, curiosity, creativity and persistence. This can be frustrating when the outside world says:
"If you can do it for something you enjoy, why can't you just do it for everything?"
But that question misses something important. The issue may not be a lack of motivation as much as difficulty regulating access to motivation. The same system that makes boring tasks incredibly difficult to start can make an interesting idea almost impossible to let go of.
Effort Regulation
Why easy things can sometimes feel harder than difficult things
ADHD can create one of the most confusing experiences of all:
"I know I can do this. So why can't I make myself do it?"
The difficulty of a task isn't always the same as the amount of effort it takes to start it. A complicated project that you find fascinating may be easier to work on than putting the washing away.
Writing an essay about something you love may be easier than answering three emails.
Learning something new may be easier than completing a familiar administrative task.
This is one reason someone with ADHD can sometimes produce an extraordinary amount of work while struggling with an apparently tiny task. It isn't necessarily a question of ability. It can be a question of whether the brain can generate enough activation and effort for that particular task. And when it does, the results can be remarkable.
Time Regulation
Where did the time go?
Time can feel strangely slippery with ADHD.
Five minutes can feel like an hour.
Three hours can disappear.
A deadline that is two weeks away can feel almost imaginary.
Then suddenly it is tomorrow.
This can make things like estimating how long something will take, leaving on time, starting early, remembering future commitments and breaking large projects into stages surprisingly difficult. Research supports the idea that people with ADHD can experience differences in how time is perceived and estimated.
But there is another side to this. When you're completely absorbed in something, you can enter a state where the outside world almost disappears.
Time can stop mattering.
You're simply there.
Music, creativity, conversation, exercise, gaming, reading, nature or an absorbing problem can produce this kind of deep immersion.
The challenge is being able to move between:
"I'm completely in this moment"
and
"I need to remember what happens next."
Circadian and Biological Regulation
When your body clock doesn't seem to agree with the rest of the world
Sleep is a major part of ADHD for many people.
You might struggle to fall asleep even when you're exhausted.
You might find mornings almost impossible.
Your natural energy might arrive late at night.
Your sleep schedule might drift.
You might feel awake when everyone else is winding down and exhausted when everyone else is starting the day.
Sleep and circadian difficulties are associated with ADHD, although there isn't one single explanation for why this happens. And sleep itself affects everything else. Poor sleep can make attention harder.
It can affect mood.
It can reduce patience.
It can make motivation harder.
It can increase emotional reactivity.
So sometimes what looks like an ADHD problem can become a feedback loop:
The aim isn't necessarily to force every person into exactly the same biological rhythm. It is to find ways of making their natural rhythms work with, rather than constantly against, the demands of life.
Sensory Regulation
When the world is too much — or wonderfully intense
This is one of the areas where the idea of regulation becomes particularly interesting. Some people with ADHD can be highly sensitive to sensory information.
A ticking clock can become impossible to ignore.
A light can feel painfully bright.
Clothing can feel unbearable.
Several people talking at once can become overwhelming.
A background noise that other people don't notice can completely destroy concentration.
But sensory sensitivity isn't only about being overwhelmed. It can also make the world incredibly vivid.
Music can send chills through your body.
A particular song can produce frisson — those sudden goosebumps and waves of emotion.
Certain textures can feel wonderful.
Food can be intensely pleasurable.
Exercise can feel exhilarating.
The smell of rain can be captivating.
Colours, sounds and physical sensations can become deeply immersive.
Some people also seek additional sensory stimulation through movement, exercise, fidgeting, loud music, strong flavours, touch or novelty.
So sensory regulation exists at both ends:
"Everything is too much."
and
"I need more."
The goal isn't necessarily to become less sensitive. It is to have greater control over how much sensory information you take in.
Social Regulation
Intensity can exist in relationships too
ADHD can affect relationships because conversations require constant regulation.
You have to listen while holding what the other person is saying in mind.
You have to wait for your turn.
You have to notice when someone has finished.
You have to regulate your emotional response.
You have to remember what happened five minutes ago.
And sometimes all of those things are difficult at once.
You might interrupt.
You might accidentally talk over someone.
You might become distracted.
You might react strongly during an argument.
You might become completely absorbed in a conversation.
But the same characteristics can also make someone:
enthusiastic, funny, expressive, spontaneous, passionate, deeply engaged.
The challenge isn't necessarily caring too much. It is regulating attention, emotion and impulse while another human being is doing the same thing.
Interoception and the Body
Listening to internal signals
This is a newer and less certain part of the picture.
Interoception is our ability to notice signals coming from inside the body:
hunger
thirst
fatigue
tension
heartbeat
physical stress
pain
body temperature
Some people with ADHD describe becoming so absorbed in something that they don't notice these signals until they become impossible to ignore.
"I suddenly realised I haven't eaten all day."
"I didn't realise how exhausted I was."
"I didn't notice I needed the toilet until it became urgent."
Research into ADHD and interoception is still developing, so this shouldn't be treated as a defining characteristic of ADHD. But it fits an interesting idea:
You can't regulate a state you haven't noticed.
So what is the common thread?
Look at all of these experiences together and a pattern begins to emerge. Maybe ADHD isn't simply about having too little attention. Maybe it involves difficulties regulating the state in which attention, motivation, emotion, energy and behaviour become available.
Think about a dimmer switch rather than an on/off switch. The problem isn't necessarily:
"The light doesn't work."
It might be:
"I can't reliably set the light to the level I need."
Sometimes it is too dim.
Sometimes it is painfully bright.
Sometimes it suddenly switches on.
Sometimes it refuses to come on until something interesting happens.
And sometimes it is exactly right.
The ADHD paradox
This may explain one of the most frustrating experiences of ADHD:
"I know I can do it."
And that's often true.
The person who cannot start the report may be capable of writing thousands of words.
The person who cannot sit through a boring meeting may be capable of concentrating for hours on something fascinating.
The person who struggles to get out of bed may run for ten miles once they are activated.
The person who is overwhelmed by sound may experience music more intensely than almost anything else.
The person who struggles to control anger may also experience love, excitement and compassion profoundly.
The person who loses track of time may become completely immersed in the present.
These things aren't necessarily contradictions.
They may be different expressions of a nervous system that is highly dependent on state and context.
Regulation, not suppression
This may be the most important distinction.
If ADHD involves regulation difficulties, the answer doesn't have to be:
"How do we make the person less emotional?"
Or:
"How do we make them less energetic?"
Or:
"How do we stop them being so sensitive?"
Those characteristics can also be part of what makes someone who they are.
Emotional intensity can become passion.
Sensitivity can become appreciation.
Curiosity can become expertise.
Spontaneity can become adventure.
Energy can become drive.
Deep interest can become mastery.
A busy mind can become creativity.
The goal is not necessarily to remove those characteristics. It is to develop greater control over them.
To turn the volume down when it is overwhelming.
To turn it up when more energy is needed.
To redirect attention.
To pause before acting.
To create motivation when interest isn't naturally there.
To recognise when the body needs rest.
To notice when sensory input is becoming too much.
To recover after becoming emotionally overwhelmed.
In other words:
Not less intensity — more control over intensity.
And what about autism?
This is where the idea of regulation becomes even more interesting. There is considerable overlap between ADHD and autism, but regulation may play out somewhat differently.
A simplified way of thinking about it is:
ADHD may often involve difficulty regulating the level, direction and timing of internal states.
Autism may often involve difficulty regulating the fit between the person and their sensory, social and environmental world.
These aren't absolute distinctions, and many people experience both.
For someone with ADHD, the question might be:
"Can I get my brain and body into the state I need for this task, at the time I need it?"
For someone with autism, it might more often be:
"Is my environment, sensory world and social situation compatible with the way my nervous system processes information?"
There is overlap in attention, emotion, sensory processing, arousal, executive functioning and recovery. But there can also be important differences. For example,
Novelty can sometimes be stimulating and motivating for someone with ADHD, whereas predictability and knowing what to expect can be particularly regulating for someone with autism.
Sensory differences are also particularly central to the diagnostic picture of autism, whereas sensory processing differences in ADHD are increasingly recognised but are not a core diagnostic criterion.
And, of course, someone can experience both.
In AuDHD, these systems can interact in complicated ways.
This points towards an even broader idea:
Regulation doesn't happen entirely inside a person.
It happens at the intersection between a nervous system and its environment. A person may struggle because something is too noisy, too bright, too unpredictable, too boring, too socially demanding, too fast, too slow — or simply because the demands of the situation don't match the state their brain is currently in.
This may help explain why the same characteristic can be a difficulty in one environment and a strength in another.
What does the research actually support?
The research isn't yet saying that ADHD is a single regulation disorder. But several parts of this picture have substantial scientific support.
Emotional regulation difficulties are well documented in ADHD, although emotional dysregulation is not currently part of the core diagnostic criteria.
Attention, inhibition and executive-function difficulties are among the most established findings in ADHD.
Research also finds differences in responses to delayed versus immediate rewards, differences in time perception, and increasing evidence of sensory-processing differences.
Researchers have also investigated arousal and "state regulation", although this evidence is more mixed.
Sleep and circadian difficulties are substantially associated with ADHD, but the relationship is complicated and likely goes in both directions.
Interoception is an interesting emerging area, but the evidence isn't yet strong enough to treat it as an established core feature.
So the evidence doesn't justify saying: "Science has proved ADHD is a regulation disorder." But it does support asking a much more interesting question:
"How much of ADHD can we understand as difficulty regulating different aspects of attention, emotion, motivation, arousal, behaviour, time and sensory experience?"
That is a question researchers are increasingly investigating. And perhaps that perspective gives us a more complete picture of ADHD than the words "attention deficit" alone ever could. Because sometimes the problem isn't that the ability isn't there.
It's that you can't always access it when you need it.
ADHD and regulation at a glance
The "strengths" in this table are potential strengths, not guaranteed ADHD benefits. The same characteristic can be helpful in one environment and difficult in another. The point is that the difficulty and the potential strength can sometimes arise from the same underlying tendency to regulate intensity, attention, motivation or stimulation differently.
