ADHD Shutdown
A state where executive function collapses entirely. You can’t think, choose, or act. Often triggered by overwhelm, sensory overload, or long stretches of understimulation. Different from sleepiness – it’s the brain going offline.
Why it matters: Recognizing a shutdown helps you respond with rest instead of self-criticism.
ADHD Tax
The financial and time cost of having ADHD: late fees, missed appointments, replaced lost items, expedited shipping, gym memberships you don’t use, food that goes bad in the fridge. Many people describe it adding up substantially over a year.
Why it matters: Naming it helps you stop treating it as personal failure. ADDitude has a deeper write-up.
Body Doubling
The practice of working alongside another person – physically or in person, on a video call, or in a coffee shop – while you each do your own task. Their presence acts as external regulation that an ADHD brain can borrow. Free, often the most effective non-medication tool.
Why it matters: It addresses three executive function gaps at once. Full guide here.
Co-regulation
A proposed process in which people attune to each other physiologically, leading to calmer focus and easier action. It is one explanation offered for why body doubling helps, not a settled one. Babies learn it from caregivers; adults benefit from it lifelong.
Why it matters: If self-regulation is hard for you, co-regulation isn’t a workaround – it’s a feature. More on body doubling.
Decision Paralysis
Being unable to choose between options – even small ones – when each has some merit, often resulting in choosing nothing. Common in ADHD because of working memory load and time blindness compounding.
Why it matters: Reducing the number of decisions you have to make in a day is one of the most underrated ADHD interventions. Related: task paralysis.
Dopamine Deficit
A commonly used shorthand for differences in how the ADHD brain handles reward and motivation. Imaging studies have reported differences in dopamine markers in ADHD, though findings vary between studies. It is one of several factors that may make low-interest tasks harder to begin.
Why it matters: It’s why “just try harder” rarely helps. Why task initiation breaks.
Emotional Regulation
The ability to manage the intensity and duration of your emotions. ADHD impairs this – emotions arrive faster, hit harder, and last longer. Small slights can feel devastating. Frustration can become rage in seconds.
Why it matters: It’s why ADHD relationships, jobs, and self-image take a beating that has nothing to do with character.
Executive Dysfunction
When one or more executive functions don’t work reliably. Common symptoms: trouble starting tasks, finishing tasks, switching tasks, regulating emotions, holding information in mind. It’s the broader category that includes task initiation deficit.
Why it matters: It’s the umbrella under which ADHD, autism, depression, and burnout all sit. Related: task initiation deficit.
Executive Function
The brain’s “management” system: the seven core skills you use to plan, start, focus, monitor, and finish what you set out to do. ADHD impairs all seven, but task initiation and working memory are usually the first to break down.
Why it matters: Once you understand executive function, a lot of what gets read as a moral failure stops looking like one.
Hyperfocus
The opposite of distraction. Intense, immersive concentration on a task – often for hours – with reduced awareness of time, hunger, and surroundings. The same dopamine system that fails task paralysis can power hyperfocus on something interesting.
Why it matters: It’s why “you can focus when you want to” is a misunderstanding. You can hyperfocus on what your brain finds rewarding – the dopamine doesn’t show up on command.
Inhibition
The executive function that lets you NOT do things – not interrupt, not blurt, not act on the first impulse. ADHD impairs inhibition, which is why interrupting, impulsive purchases, and saying things you immediately regret are so common.
Why it matters: It’s not poor manners – it’s the brain not braking.
Late Diagnosis
Being diagnosed with ADHD as an adult, often after years of struggle, mislabeling as lazy or anxious, or burning out one too many times. Especially common in women, who are systematically underdiagnosed in childhood.
Why it matters: If you’re recently diagnosed, the grief is real. So is the relief of finally having a name for it.
Masking
Consciously hiding ADHD traits to fit in: forcing stillness, suppressing stimming, mimicking neurotypical behavior, working twice as hard to look like everyone else. Effective short-term. Exhausting long-term. Often a path to burnout.
Why it matters: Most late-diagnosed ADHD adults masked for years without realizing what they were doing.
Neurodivergent
A descriptor for brains that develop and function differently from the typical norm – including ADHD, autism, dyslexia, dyspraxia, and more. Coined as a non-pathologizing alternative to “disordered.”
Why it matters: Using “neurodivergent” reframes ADHD as a difference rather than a defect.
Perfectionism Paralysis
Being unable to start because you can’t guarantee the result will be perfect. Especially common in ADHD because intense self-criticism plus executive dysfunction equals “if I can’t do it right, I won’t do it at all.”
Why it matters: Lowering the bar is often the unlock – done badly beats not done. Related: procrastination vs paralysis.
The Pomodoro Technique
A focus method of 25-minute work blocks separated by 5-minute breaks. Used widely for ADHD because the bounded time horizon reduces overwhelm and the structure provides external pacing.
Why it matters: It’s a sustain tool. Pair it with a launch tool like the 2-minute rule.
Rejection Sensitive Dysphoria (RSD)
Extreme emotional pain triggered by perceived rejection, criticism, or failure. Different from “being too sensitive” – it’s a neurological response that can leave you reeling for days from a comment most people would forget in minutes.
Why it matters: Up to 99% of people with ADHD experience some form of RSD, according to clinical observations summarized by ADDitude magazine.
Self-Regulation
The brain’s ability to manage your own behavior, emotions, and attention without external prompting. Russell Barkley’s framework places ADHD as fundamentally a self-regulation disorder.
Why it matters: External tools (apps, body doubling, schedules) work because they replace internal regulation that ADHD brains struggle to generate.
Stimming
Self-stimulatory behavior: fidgeting, tapping, rocking, humming, doodling. Often misread as distractibility, but stimming usually helps ADHD brains regulate and focus, not the opposite.
Why it matters: If you stim, it’s probably helping you. Suppressing it costs you something.
Sustained Attention
The ability to maintain focus on something for an extended time, especially when it isn’t intrinsically rewarding. ADHD makes this enormously variable: 5 minutes for boring tasks, 5 hours for novel ones.
Why it matters: Once you know your sustained attention is biological, you stop demanding the impossible from yourself.
Task Initiation Deficit
A measurable executive function failure where your brain can’t get from “I should do this” to “I’m doing it,” even when you genuinely want to. It’s not laziness – it’s a documented neurological pattern, most often part of ADHD.
Why it matters: It is the term researchers use for what many people experience as task paralysis. It is not a formal diagnosis. Full explainer here.
Task Paralysis
The acute experience of being frozen, unable to start a task even when there are no obstacles. Your body feels heavy. Your thoughts spiral. The harder you try to push yourself, the more stuck you get.
Why it matters: It’s the moment many people search for help, and the central problem FOCO is built around. Pillar guide here.
Time Blindness
The ADHD difficulty in perceiving time accurately. A 30-minute task can feel like a 3-hour ordeal. “Five more minutes” can become two hours. The internal clock runs differently from a neurotypical brain’s.
Why it matters: It’s why deadlines hit late, meetings start by surprise, and “I have plenty of time” so often turns into “I’m completely out of time.”
The 2-Minute Rule
A productivity technique that says: shrink your first action until you can do it in under two minutes. For ADHD specifically, it helps because it shrinks the first action, which is where starting most often stalls.
Why it matters: Many people describe it as the closest thing to a reliable unlock they have found. Full guide here.
Working Memory
The mental scratchpad your brain uses to hold information in active use. ADHD reduces working memory capacity – which is why instructions slip, you walk into rooms and forget why, and large tasks feel impossibly heavy.
Why it matters: When you “forget” what you were doing, this is usually why. Externalizing tasks (paper, apps) compensates for it directly.
The Bottom Line
If something on this list described you, you’re not alone in it. Each of these terms exists because thousands of researchers, clinicians, and ADHD adults named what they were experiencing, again and again, until the experience had a word for it.
You are not lazy. You are not unmotivated. You have a brain that needs different tools – and now you know what to call them.
