ADHD, in examples — not in a quiz

What inattention and hyperactivity-impulsivity look like in a life. A pattern, across settings, with a childhood trail. Not a test you can pass on a bad week.

7 minute readEvidence last reviewed: 1 September 2026

People do not arrive at clinic saying “Criterion A2(d)”. They arrive saying they lose the morning, interrupt the people they love, and cannot make a form stay finished. Guidelines still have to translate that life into a persistent pattern of inattention and/or hyperactivity-impulsivity. This page is the translation in the other direction: construct into examples. It is not a checklist that can diagnose you.

Claim
  1. 1 · Statement

    Clinical guidelines model ADHD as a persistent pattern of inattention and/or hyperactivity-impulsivity, with features present in more than one setting and with several signs in childhood, even if recognition comes later. Educational examples of those features are not a diagnostic test, a severity score, or a reason to start or stop a medicine.

  2. 2 · Classification

    Established. The construct is set out in AADPA 2022 and NICE NG87, which rest on DSM-5 / ICD framing.

  3. 3 · Papers

  4. 4 · Claim limitation

    A list of examples will match almost anyone on a bad week. Persistence, settings, developmental history and impairment are the parts a website cannot complete for you.

Inattention, as it tends to look

  • Detail slip — a line in a form, a step in a recipe, a figure in a spreadsheet. Not because the work is beyond them.
  • Sustaining attention — meetings, homework, a conversation. The mind leaves without deciding to leave.
  • Appearing not to listen — spoken to directly; the words do not land. Often called rude.
  • Follow-through — the email started, the tax return open, several loops, none closed.
  • Organisation — deadlines, bags, the order of a morning. Systems built, then abandoned.
  • Avoiding effortful tasks — forms, long reading, admin. Aversive load, not a moral verdict.
  • Losing things — keys, phone, glasses, the object that was in the hand a minute ago.
  • Distractibility — a notification, a thought, a sound. The original task is still open. It is no longer occupied.
  • Forgetfulness in daily life — appointments, returning a call, paying a bill, the reason for standing up.

Hyperactivity and impulsivity, as they tend to look

  • Fidget, tap, leave the seat when sitting is expected. In adults this is often an inner motor more than running the corridor.
  • Difficulty with quiet leisure. A film, a waiting room, a classroom that requires stillness.
  • On the go — described by others as driven; described by the person as unable to downshift.
  • More words than the conversation budgeted for. Interrupting as the thought arriving faster than the pause.
  • Difficulty waiting — queues, turn-taking, the spinning wheel on a website.
  • Blurted answers, walked-into conversations. Not always intended as dominance.

The parts a list cannot do

  • A pattern, not a bad week.
  • More than one setting — home and school, or work and relationships.
  • Several features present in childhood, even if nobody had the language then. Late recognition is not late onset.
  • Interference with life. Difference without impairment is not what these criteria are for.
  • Not better explained, on its own, by another condition — and not cancelled by another condition either.
