ADHD red flags warranting referral in young children

A young child seldom presents with "ADHD" — they present with a pattern of activity, impulsivity or inattention that a parent or teacher flags. The clinician's task is to separate developmentally typical exuberance from a referral-worthy signal.

In short

In pre-school and early-school children, ADHD is a clinical judgement of age-inappropriate inattention, hyperactivity and impulsivity that is persistent (≥6 months), pervasive across at least two settings (home, childcare/school), and causing functional impairment. Refer when these features exceed developmental expectation and are not better explained by hearing loss, sleep disorder, anxiety or global delay. Caution: a confident ADHD label below ~4–5 years is rarely appropriate — assess and monitor rather than diagnose.

Red flags that warrant referral

Inattention

• Cannot sustain attention on age-appropriate play or tasks well below same-age peers
• Does not follow simple instructions; rapid, repeated shifting between activities
• Marked forgetfulness and disorganisation disproportionate to age

Hyperactivity–impulsivity

• Constant, driven motor activity that others reliably remark on, not just liveliness
• Cannot remain seated for circle time or meals when peers can
• Frequent interrupting, difficulty awaiting turn, acting before thinking — with injury risk or social fallout

Always weigh

• Pervasiveness across ≥2 settings and duration ≥6 months
• Genuine functional impairment — learning, peer relationships, family stress
• Comorbidity or differentials: language delay, ASD, anxiety, sleep-disordered breathing, hearing loss, lead exposure

When to refer

A child need not meet full ICD-11 6A05 criteria to be referred. Persistent, cross-setting, impairing symptoms — especially with a co-occurring developmental concern — justify onward multidisciplinary assessment. Arrange hearing and vision checks in parallel, and consider behavioural therapy support while assessment is organised.
