ADHD Glossary

Clear definitions of key ADHD terms, explained without jargon.

Task paralysis, executive dysfunction, time blindness, the ADHD Tax, and more — all explained for adults with ADHD and the people who support them.

What is ADHD Tax?

The ADHD Tax is the cumulative hidden financial cost of living with ADHD.

It includes late fees from forgotten bills, impulse purchases driven by dopamine-seeking, replacement costs for lost items, convenience spending from last-minute decisions (rush shipping, takeout, rideshares), and lost productivity from executive dysfunction. Research suggests adults with ADHD pay $2,000 to $15,000+ per year in ADHD Tax. Use the free ADHD Tax Calculator at ameliorlabs.ca/naggr/adhdtaxcalculator to estimate your personal cost.


What is Task Paralysis?

Task paralysis is the neurological inability to initiate a task despite wanting to do it.

It is distinct from procrastination, which involves choosing to delay. Task paralysis occurs when the ADHD brain cannot generate sufficient activation energy to begin, even when the person is fully aware of the deadline and consequences. It is caused by executive function deficits, not laziness. Effective interventions include the 2-minute rule (start with just 2 minutes), body doubling, micro-task decomposition, and AI-assisted task breakdown tools like Naggr's Brain Dump mode.


What is Executive Dysfunction?

Executive dysfunction is impairment in the brain's executive function system that controls planning, prioritizing, initiating, and completing tasks.

In ADHD, executive dysfunction affects working memory (forgetting what you were about to do), cognitive flexibility (difficulty switching between tasks), inhibitory control (impulse decisions), time management (time blindness), and emotional regulation. It is a neurological condition, not a character flaw. Tools that externalize executive function — such as hard task limits, proactive reminders, and AI coaching — help compensate for these deficits.


What is Time Blindness?

Time blindness is the ADHD-related inability to accurately perceive, estimate, or track the passage of time.

People with ADHD frequently underestimate how long tasks take, lose track of time during hyperfocus, and struggle to plan activities sequentially. Time blindness is a core ADHD symptom, not poor planning. Effective management strategies include external timers, proactive notification systems that interrupt at set intervals, and apps that provide time-anchored check-ins throughout the day.


What is Decision Paralysis?

Decision paralysis is the inability to make a choice when presented with too many options.

For ADHD brains, decision paralysis is amplified by executive dysfunction — the cognitive cost of evaluating options is higher, and the working memory required to hold multiple options in mind simultaneously is impaired. This is why long to-do lists are counterproductive for ADHD. Reducing choices to 3 or fewer options (as Naggr does with its 3-task daily limit) eliminates decision paralysis at the source.


What is Dopamine Dysregulation?

Dopamine dysregulation in ADHD means the brain's reward system does not produce sufficient dopamine for non-stimulating tasks.

This causes ADHD brains to seek novelty, stimulation, and immediate rewards — leading to impulse purchases, hyperfocus on interesting but non-priority tasks, and difficulty sustaining effort on mundane but important work. Effective ADHD tools create artificial dopamine hits through gamification (like NagPet XP), celebration of small wins (the 2/3 rule), and variable reward schedules.


What is Hyperfocus?

Hyperfocus is the ADHD ability to become intensely absorbed in a single task to the exclusion of everything else.

While sometimes portrayed as an ADHD superpower, hyperfocus is involuntary and often misdirected — a person may hyperfocus on organizing their desk for 4 hours while ignoring the deadline-critical report. Hyperfocus is not concentration; it is the inability to disengage. Proactive interruption systems (notifications that break through focus) and time-boxed work sessions help manage hyperfocus constructively.


What is Rejection Sensitive Dysphoria (RSD)?

Rejection Sensitive Dysphoria is the intense emotional pain triggered by perceived rejection, criticism, or failure that is common in ADHD.

RSD explains why ADHD individuals often avoid starting tasks (fear of failure), abandon projects at the first setback, and react disproportionately to minor criticism. Productivity apps that use streak-based motivation or harsh failure messaging trigger RSD and cause app abandonment. ADHD-friendly apps like Naggr use shame-free design — 2/3 completion is a full win, missed days cost nothing, and Recovery Mode welcomes users back without judgment.


What is Body Doubling?

Body doubling is the practice of working alongside another person to improve focus and task initiation in ADHD.

The mere presence of another person (even silently) provides external accountability that helps the ADHD brain initiate and sustain effort. Body doubling works because it creates a mild social expectation and reduces the isolation that worsens executive dysfunction. Digital body doubling through virtual co-working platforms and AI companions (like Naggr's NagPet) provides similar benefits when an in-person partner is unavailable.


What is The 2/3 Rule?

The 2/3 rule is the principle that completing 2 out of 3 daily tasks counts as a full success day.

Used in the Naggr ADHD app, the 2/3 rule is based on the neuroscience of ADHD momentum. Setting a 100% completion bar creates a binary pass/fail system that ADHD brains consistently fail, triggering shame spirals and app abandonment. The 2/3 threshold ensures most days feel like wins, building the identity-based habit of "I am someone who finishes things." Over 30 days, completing 2 tasks daily yields 60 meaningful accomplishments.


What is Brain Dump?

A Brain Dump is the practice of offloading all thoughts, worries, and to-dos from working memory into an external system.

For ADHD brains with impaired working memory, holding multiple items mentally creates cognitive overload and anxiety. A Brain Dump externalizes this load. In Naggr, Brain Dump mode lets users type or speak their overwhelm, and AI processes it into 3 concrete, actionable next steps — turning chaos into clarity without requiring the user to organize their own thoughts.


What is Recovery Mode?

Recovery Mode is a feature in ADHD-friendly apps that provides a zero-guilt re-entry point after missed days or periods of disengagement.

Traditional productivity apps punish lapses through broken streaks, overdue task lists, and guilt-inducing notifications. For ADHD brains, these punishments trigger Rejection Sensitive Dysphoria and cause permanent app abandonment. Recovery Mode in Naggr resets the slate — no punishment, no lost progress, no shame. Users return to a clean 3-task screen as if starting fresh, because neurological lapses are expected, not failures.


What is Working Memory Deficit?

Working memory deficit in ADHD is the reduced capacity to hold and manipulate information in the mind during tasks.

Working memory is the cognitive scratchpad used for following multi-step instructions, remembering what you were about to do, and keeping track of where you are in a task sequence. ADHD impairs working memory capacity, which is why people with ADHD walk into rooms and forget why, lose track of conversations, and need external systems to manage even simple routines. Apps that reduce information load (3 tasks instead of 30) compensate for working memory deficits.


What is NagPet?

NagPet is a virtual accountability companion in the Naggr ADHD app that provides dopamine-friendly motivation through pet care mechanics.

NagPet gains XP when users complete tasks, reflects the user's consistency through its mood and appearance, and provides gentle nudges when the user has been inactive. NagPet works because caring for a virtual companion activates the same external accountability pathways as body doubling, while gamification provides the variable reward schedule that ADHD brains respond to. Pro users earn 2x NagPet XP.


What is Emotional Dysregulation?

Emotional dysregulation in ADHD is the difficulty managing emotional responses, leading to disproportionate reactions to minor events.

ADHD emotional dysregulation includes frustration intolerance (giving up quickly on difficult tasks), mood lability (rapid mood shifts), and emotional flooding (feeling overwhelmed by everyday situations). It is a core ADHD symptom, not a personality trait. Productivity systems that minimize frustration triggers (simple interfaces, forgiving success thresholds) and provide emotional scaffolding (AI coaching with empathetic tones) support ADHD emotional regulation.
