ADHD Glossary: Terms Explained in Plain English
The words people use for ADHD life, explained without jargon. Each term says whether it is a clinical term, something studied in research, or community language, so you know how much weight to give it.
A
- ADHD burnoutCommunity term, not a diagnosisADHD burnout is community language for deep physical and mental exhaustion after a long stretch of compensating for ADHD: overworking, masking and holding everything together. It is not a clinical diagnosis. Rest that would normally help does not seem to, and coping strategies that used to work stop working.
- ADHD taxCommunity term, not a diagnosisThe 'ADHD tax' is community slang for the extra money, time and stress that ADHD symptoms cost: late fees, forgotten subscriptions, spoiled food, rush shipping and replacing lost items. It is not a formal term, but it names real costs linked to forgetfulness and impulsivity.

C
D
- Doom pileCommunity term, not a diagnosisA doom pile is a stack of mixed items, like mail, receipts, chargers and clothes, that you moved somewhere to deal with later. Online, DOOM is often read as 'Didn't Organize, Only Moved.' It is community language, common among people with ADHD, for clutter built from postponed decisions.
- Dopamine menuCommunity term, not a diagnosisA dopamine menu is a personal list of quick, healthy activities that give you a lift of energy or mood, organized like a restaurant menu into starters, mains, sides and desserts. People with ADHD use it to pick something helpful in a low moment instead of defaulting to scrolling.
E
- Emotional dysregulationStudied in researchEmotional dysregulation is difficulty managing the intensity and duration of emotions: feelings rise fast, hit hard and take longer to settle. It is not in the formal ADHD criteria, but research shows it is common in ADHD, including in adults, and it often causes more day-to-day distress than inattention.
- Executive dysfunctionClinical termExecutive dysfunction means difficulty with executive functions, the brain's self-management skills such as planning, starting tasks, holding information in mind, shifting between activities and regulating emotions. It is a central feature of ADHD, though it also appears in other conditions, and it is about managing skills, not intelligence.
H
- HyperfixationCommunity term, not a diagnosisHyperfixation is community language for an intense interest that takes over your thoughts and free time for days, weeks or months, often followed by a sudden loss of interest. Hyperfocus describes a single absorbed session; hyperfixation describes the longer obsession. It is not a clinical term.
- HyperfocusStudied in researchHyperfocus is a state of intense, absorbed concentration on something interesting or rewarding, to the point of losing track of time and ignoring needs like food or sleep. It is not in the official ADHD criteria, but studies find adults with more ADHD symptoms report hyperfocus more often.

R
- Rejection sensitive dysphoria (RSD)Community term, not a diagnosisRejection sensitive dysphoria (RSD) describes sudden, intense emotional pain after real or perceived rejection, criticism or disapproval. The term was popularized by psychiatrist William Dodson and is widely reported by people with ADHD. It is not an official diagnosis, and research on it is still early, but emotional dysregulation in ADHD is well documented.
- Revenge bedtime procrastinationCommunity term, not a diagnosisRevenge bedtime procrastination means delaying sleep to claim personal time you did not get during the day, even when you are tired and know you will regret it. The phrase spread online from a Chinese expression around 2020. It is not ADHD-specific, but it is very common in ADHD.
S
- Sensory overloadStudied in researchSensory overload happens when sounds, lights, textures, smells or crowds become more than your brain can process, leading to irritability, panic or a need to escape. It is common in ADHD and autism, though it is not part of the formal ADHD criteria.
- StimmingClinical termStimming, short for self-stimulatory behavior, means repetitive movements, sounds or touch that help regulate focus, energy or emotions, such as bouncing a leg, clicking a pen or twirling hair. It is often discussed with autism, but people with ADHD stim too, and it is usually harmless.
T
- Task paralysisCommunity term, not a diagnosisTask paralysis, often called ADHD paralysis, is the state of knowing what you need to do, wanting to do it, and still being unable to start. It is community language rather than a diagnosis, and it is usually linked to difficulties with starting tasks, prioritizing and managing overwhelm, not to laziness.
- Task switching (transitions)Studied in researchTask switching means moving your attention from one activity to another, like stopping work to cook or leaving the couch to get ready. Difficulty with transitions is common in ADHD: stopping something absorbing and starting something new both cost effort, so the gap between them can stretch.
- Time blindnessStudied in researchTime blindness is a common ADHD experience of not feeling time pass: minutes and hours slip by unnoticed, tasks take far longer than expected, and future deadlines do not feel real until they are close. It is not a formal diagnosis, but research does link ADHD with differences in time perception.
W
- Waiting modeCommunity term, not a diagnosisWaiting mode is community language for the ADHD experience of being unable to start anything before an upcoming event, even one hours away. The appointment takes over the day: you wait, check the time and get little done. It is not a clinical term, but it is linked to time management difficulties.
- Wall of AwfulCommunity term, not a diagnosisThe Wall of Awful is a metaphor, popularized by ADHD coach Brendan Mahan, for the emotional barrier that builds up around a task after repeated disappointment, shame or failure. Each bad experience adds a brick, so the task feels heavier than it really is. It is a coaching concept, not a diagnosis.
- Working memoryClinical termWorking memory is the brain's short-term notepad: the ability to hold information in mind while you use it, like a phone number, the next step of a recipe or what someone just asked. It is one of the executive functions, and difficulties with it are common in ADHD.
