ADHD (ICD-11 6A05) is a common, recognised difference in how a child's brain manages attention, activity and impulse control — not bad behaviour or low intelligence. It appears as inattentive, hyperactive-impulsive or combined patterns across settings. Diagnosis is made only by qualified clinicians, and children thrive with the right support.

*Many parents notice their child seems to run on a different rhythm — more movement, more distraction, more energy — and wonder if there's a name for it.*

## In short
ADHD — attention deficit hyperactivity disorder — is a common, well-recognised pattern in how a child's brain manages **attention, activity and impulse control**. Children with ADHD may find it harder to stay focused, sit still, or pause before acting, in ways that are stronger and more persistent than usual for their age. It is not bad behaviour, poor parenting, or low intelligence — it is a difference in how the brain regulates attention and energy, and it is very supportable.

## Understanding it simply
Doctors group ADHD (classified by the WHO as **ICD-11 6A05**) into three patterns: mainly inattentive (drifting, forgetful, easily distracted), mainly hyperactive-impulsive (always on the go, interrupting, restless), or a combination of both. To be considered ADHD, these traits need to show up **across settings** — home and school — and genuinely affect daily life, not just appear on a tiring day. Many children with ADHD are bright, creative and energetic; with the right understanding and [behaviour support](/behaviour-therapy), they thrive at home and in the classroom.

## The Pinnacle way
A clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed **only at a Pinnacle Blooms Network centre, under qualified clinician care** — never from an online form or checklist. From there, your family gets a clear baseline and a plan you can follow. Learn more about [ADHD support](/adhd).
