Signs of ADHD a nurse should watch for in a young child

Young children are naturally energetic and impulsive — so the nurse's eye is for patterns that are pervasive, persistent and disproportionate to age, not for normal busy-ness.

In short

In a young child, watch for a persistent pattern of inattention, hyperactivity and impulsivity that is present across settings (home, crèche, clinic), lasts well beyond a passing phase, and is clearly beyond what is expected for the child's developmental age. ADHD (WHO ICD-11 6A05) is not reliably identified before around 4–5 years, and a single observation never confirms it — your role is to notice, document objectively and route for structured assessment. The diagnosis is a clinical one made over time, not from a checklist in a single visit.

Signs worth documenting

Inattention

• Difficulty sustaining attention on play or tasks; quickly moves from one activity to another.
• Appears not to listen when spoken to directly; loses or forgets items frequently.
• Easily distracted, struggles to follow multi-step instructions appropriate to age.

Hyperactivity

• Constant movement — runs, climbs or fidgets in situations where settling is expected.
• Difficulty staying seated; "driven by a motor" quality.

Impulsivity

• Acts before thinking, interrupts, struggles to wait or take turns.
• Difficulty with transitions and frequent unintentional risk-taking.

Clinical framing for the nurse: ask whether the behaviour is pervasive (more than one setting), persistent (≥6 months), and impairing (affecting learning, relationships or safety). Always screen for differentials — hearing or vision deficits, sleep disruption, anxiety, language delay, iron deficiency or recent psychosocial stress — which can mimic ADHD presentations.

When to refer

Refer for structured developmental assessment when concerns are consistent across settings and carers, when behaviour impairs function or safety, or when a parent raises persistent worry. Avoid labelling at the bedside; instead provide objective, behaviour-specific documentation to support the clinician's evaluation.

The Pinnacle way

AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app, screener or single observation. Our clinician-administered structured assessment builds a precise developmental profile across attention, behaviour and adaptive function — see how the AbilityScore® works.
