ICF reframes ADHD as a functioning profile rather than a deficit list — most useful before a formal label is clinically appropriate.","answer_md":"*Before we reach for a diagnostic code, the clinical question that actually shapes therapy is functional: where, across a young child's day, does attention-regulation difficulty show up?*\n\n## In short\nIn early childhood, ADHD (ICD-11 **6A05**) is best understood not as a deficit list but through the WHO **ICF** lens — across **Body Functions**, **Activities & Participation**, and **Environmental & Personal Factors**. The functioning domains most affected are attention and other mental functions (b1), play and learning, communication and interpersonal interactions (Activities & Participation, d-codes), and self-care/daily routines — all heavily modulated by the child's home, preschool and family context. ICF reframes the picture from *what is wrong with the child* to *what the child can do, where, and with what support*.\n\n## The ICF functioning domains in practice\n**Body Functions (b)**\n- **b140 Attention functions** — sustaining, shifting and dividing attention; the core feature in early presentations.\n- **b130 Energy and drive functions** — activity level, impulse regulation, motivation.\n- **b164 Higher-level cognitive functions** — emerging executive skills (inhibition, working memory) appropriate to age.\n- **b152 Emotional functions** — regulation, frustration tolerance, reactivity.\n\n**Activities & Participation (d)**\n- **d160–d179 Applying knowledge** — focusing attention, sustaining a task at play.\n- **d2 General tasks & demands** — following routines, completing a single activity.\n- **d3 Communication** and **d7 Interpersonal interactions** — turn-taking, peer play, responding to instruction.\n- **d8 Major life areas** — early preschool participation and learning.\n- **d5 Self-care** — dressing, mealtimes, settling — often disrupted by impulsivity and distractibility.\n\n**Contextual factors**\n- **Environmental factors (e)** — predictability of routine, adult scaffolding, sensory load of the setting; these can be facilitators or barriers.\n- **Personal factors** — temperament, age, co-occurring profile.\n\nA note on age: a formal ADHD label is rarely meaningful in toddlers, where high activity and short attention spans are developmentally typical. The ICF profile is therefore the more useful early-childhood tool — it documents functioning and the support that helps, supporting a watch-and-monitor stance until a structured clinical assessment becomes appropriate (commonly from preschool age onward, per NICE NG87).\n\n## When to refer\nRefer for structured developmental review when attention, activity and impulse patterns are **pervasive across settings** (home and preschool), **persistent**, and producing **functional impact** beyond age-typical variation — and always sooner where there is co-occurring developmental, communication or learning concern.\n\n## The Pinnacle way\nA clinical **AbilityScore®** and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a screen, a form or an article.
