In the WHO ICF, inattention maps to b140 — Attention functions, within the Mental functions chapter of Body Functions. This describes the specific mental functions of focusing and sustaining, shifting, dividing and sharing attention. It is distinct from how attention shows up in daily life, captured under Activities and Participation (e.g. d160 Focusing attention), and from diagnostic labels such as ADHD in ICD-11.

*Inattention in early childhood is not first a label — in the ICF it is a described function of the developing mind, anchored in attention itself.*

## In short
Within the WHO **International Classification of Functioning, Disability and Health (ICF)**, inattention maps to **b140 — Attention functions**, a sub-category of the **Mental functions** chapter (Body Functions, Chapter 1). Specifically, b140 covers the specific mental functions of focusing on an external stimulus or internal experience for the required period — including sustaining, shifting, dividing and sharing attention. Inattention is thus described as a variation in these attention functions, not as a free-standing diagnosis.

## The ICF framing
The ICF deliberately separates the *function* (the body-function level, where b140 sits) from its real-world consequences. So inattention as **b140** is distinct from how it shows up in a child's life — which the ICF captures through **Activities and Participation**, for example *d160 Focusing attention*, *d161 Directing attention*, and the learning and play codes (*d130–d159*, *d880*). In early childhood this distinction matters: a young child's attention span is still maturing rapidly, so a b140 description is read alongside age expectations and contextual (environmental and personal) factors, never in isolation. For clinical and epidemiological purposes, ICF coding complements — rather than replaces — diagnostic systems such as the ICD; ADHD as a disorder is classified separately in ICD-11, while b140 describes the underlying functional dimension.

## Why this matters for measurement
For researchers and clinicians, mapping inattention to b140 supports a strengths-and-needs profile rather than a binary verdict. It lets a child's attention be documented functionally, linked to participation codes, and tracked over time as development unfolds — an approach well suited to early childhood, where function is dynamic and highly context-dependent.

## The Pinnacle way
This is general, classification-level information, not a diagnosis — a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated), a clinician-administered structured assessment, and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care, never from an app or form. Our teams describe attention functionally and build individualised plans drawing on [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) and allied supports.
