What are the types or levels of ADHD?

"What type does my child have?" is one of the first questions parents ask — and the honest, reassuring answer is that ADHD isn't a ladder of severity so much as a set of patterns.

In short

Under the WHO's ICD-11, ADHD (6A05) is described by three presentations rather than strict 'levels': a predominantly inattentive presentation, a predominantly hyperactive-impulsive presentation, and a combined presentation where both patterns appear together. A child's presentation can also shift as they grow — the picture at five is not fixed for life. Severity (how much it affects daily life) is judged separately by a clinician, not by a fixed scale you can score at home.

The three presentations, simply

• Predominantly inattentive — the child finds it hard to sustain attention, is easily distracted, may seem forgetful, loses things, or drifts off mid-task. This pattern is often quieter and so noticed later, especially in girls.
• Predominantly hyperactive-impulsive — the child is constantly on the go, fidgets, struggles to wait or stay seated, talks a great deal, and acts before thinking.
• Combined — features of both inattention and hyperactivity-impulsivity are present together. This is the most commonly recognised picture in childhood.

Clinicians describe how much these patterns affect a child's day — at home, at school, with friends — as mild, moderate or more significant. That judgement of impact is what guides support, and it is always made by a qualified professional who sees the whole child, not from a label alone.

When to seek a check

If attention, activity or impulsivity is causing real difficulty across more than one setting — say both home and school — and has done so for several months, it is worth a developmental check. ADHD is recognised reliably in the school years, not in toddlers, and a calm, structured assessment brings clarity rather than worry.

The Pinnacle way

A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online form or this page. Understanding which presentation fits your child is the start of a plan you can actually follow.
