Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited

ADHD is one of the most common neurodevelopmental conditions of childhood, affecting roughly 5 to 7 in every 100 school-aged children worldwide. It is recognised across all backgrounds, more often in boys, and is usually identified in the school years when attention demands rise. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.

*ADHD is one of the most common ways a child's developing brain works differently — and recognising how often it occurs helps replace worry with understanding.*

## In short
Attention deficit hyperactivity disorder (ADHD) is **one of the most common neurodevelopmental conditions of childhood**, affecting roughly **5 to 7 in every 100 school-aged children** worldwide. It is seen across every country, culture and background, and is more often recognised in boys — partly because girls more frequently show quieter, inattentive patterns that are easy to miss. Being common does not make it less real: with the right understanding and support, children with ADHD thrive.

## What the numbers mean
- **Around 5–7%** of children and adolescents meet criteria for ADHD internationally — that means most classrooms have at least one or two children who experience it.
- **It is recognised more often in boys**, but this partly reflects that girls tend to show inattentive rather than hyperactive patterns, so many girls are identified later or not at all.
- **It often travels alongside other things** — such as learning differences, anxiety, or sleep difficulties — which is why a whole-child view matters.
- **It is genuinely developmental**, not a result of poor parenting, screen time alone, or lack of discipline. The behaviours reflect how attention, activity and impulse-control are developing in your child's brain.

ADHD is usually recognised in the **school years**, when demands on sitting still, sustained attention and organisation increase. Brief restlessness or distractibility in a young child is common and expected — what matters is a *consistent* pattern across home, school and play that affects everyday life.

## When to seek a check
Consider a developmental check if you notice persistent difficulty paying attention, frequent restlessness or impulsivity, or trouble following routines — and these patterns show up in **more than one setting** (such as both home and school) and are affecting learning, friendships or self-esteem. The earlier a child's profile is understood, the sooner the right support can be put in place.
