ADHD is Not a Deficit of Attention—It’s a Disorder of Dysregulation
Posted on 20th February 2025 at 13:51
For decades, ADHD (Attention Deficit Hyperactivity Disorder) has been misnamed and misunderstood. The term "attention deficit" suggests that people with ADHD simply lack attention, but anyone who has lived with or observed ADHD knows this isn't true.
ADHD is not about too little attention, it’s about inconsistent attention regulation. Sometimes, focus slips away too easily, and other times, it locks in so tightly that breaking free feels impossible. This isn’t a failure of willpower, it’s a neurological issue of dysregulation.
When we shift the way we talk about ADHD from "attention deficit" to "attention dysregulation," suddenly, everything starts to make sense.
ADHD as a Disorder of Dysregulation
The best way to understand ADHD is through the lens of dysregulation—the inability to properly balance certain brain functions. ADHD affects much more than just attention; it also impacts emotions, sensory processing, sleep, motivation, and impulse control.
At its core, ADHD is a problem of the brain’s ability to regulate itself, not just focus, but when and how it applies focus, emotions, and motivation.
The Regulation Model of ADHD Attention
ADHD can cause focus to swing between two extremes:
Hyperfocus: Too Much Regulation (Stuck 'On')
When engaged in something interesting, an ADHD brain locks in and struggles to shift away.
This can be a superpower when harnessed effectively but highly impairing when it leads to neglecting other responsibilities.
Breaking someone out of hyperfocus is like waking them from deep REM sleep—jarring, frustrating, and sometimes infuriating.
Interruptions during hyperfocus can trigger intense frustration or anger, because mentally shifting gears isn’t easy.
Distractibility: Too Little Regulation (Stuck 'Off')
When a task isn’t stimulating enough, an ADHD brain can’t maintain focus, no matter how important the task is.
This explains why routine or repetitive tasks (emails, paperwork, chores) can feel almost physically painful to engage with.
It’s not a lack of intelligence or effort, it’s the brain’s dopamine system failing to keep attention locked in.
Task-Switching: Regulation Breakdown
Moving between tasks can be especially difficult because ADHD brains struggle to release attention from one task and engage in another.
This is why transitions—like stopping a favorite activity to start something new—are mentally exhausting and frustrating.
It’s not stubbornness; it’s the neurological cost of switching mental gears.
Beyond Attention: Other Dysregulated Systems in ADHD
ADHD is more than an attention disorder—it involves dysregulation across multiple systems, including:
The Reward System
ADHD brains have lower baseline dopamine, which makes everyday tasks feel unmotivating.
External structure, deadlines, or novelty help because they artificially boost dopamine levels.
This is why ADHD people often procrastinate until the last minute, urgency temporarily overrides the dopamine deficit.
The Emotional System
Emotional responses in ADHD are intense and hard to regulate.
"Criticism sensitivity" (often mislabeled as "rejection sensitivity") is common because ADHD brains struggle to de-escalate emotional reactions.
Mood swings aren't bipolar disorder—they're rapid shifts in dopamine and emotional regulation.
The Sensory System
Many ADHD individuals experience sensory processing differences, leading to hypersensitivity or sensory-seeking behaviors.
Background noise, certain textures, or even subtle sensory inputs can be overwhelming and distracting.
The Sleep System
ADHD brains often struggle with delayed sleep onset, meaning it’s hard to fall asleep at a typical time.
Circadian rhythms are dysregulated, making waking up and maintaining energy levels inconsistent.
Sleep deprivation intensifies ADHD symptoms, creating a vicious cycle.
The Immune System & Gut-Brain Axis
There is increasing evidence that ADHD is linked to immune system dysregulation, with higher rates of allergies, asthma, and autoimmune conditions.
The gut microbiome plays a role in dopamine production, and research suggests that microbiome differences may contribute to ADHD symptoms.
Why This Model is So Important
By shifting from a "deficit-based" view to a "dysregulation model," we create a more accurate and empowering way to talk about ADHD.
It Explains Contradictions
ADHD isn’t a disorder of "not paying attention." It’s a disorder of inconsistent control over attention.
Hyperfocus and distractibility aren’t opposites—they are two sides of the same problem: regulation failure.
It Helps Reduce Stigma
ADHD isn’t about laziness or bad behavior—it’s a biological issue affecting brain function and self-regulation.
Understanding ADHD through dysregulation shows why external supports, accommodations, and strategies are essential.
It Creates More Effective Support Strategies
Instead of telling ADHD individuals to "just try harder," we can focus on harnessing strengths, creating structure, and using tools that support regulation.
Medication, therapy, lifestyle changes, and assistive technology can help rebalance dysregulated systems.
If ADHD is a disorder of dysregulation, should the name change? Many advocates argue that terms like “Attention Dysregulation Disorder” (ADD) or “Executive Function Dysregulation” would better describe the condition.
Regardless of the name, one thing is clear: ADHD is not a deficit of attention. It is a dysregulation disorder affecting multiple systems, attention, emotions, reward, sensory processing, and more.
By shifting how we talk about ADHD, we create better understanding, better accommodations, and better support for the millions of people navigating this incredible but challenging neurotype.
