Are children with ADHD and child intelligence less smart? 

No, children with ADHD are not less smart. The idea that there is a link between ADHD and child intelligence is based on misunderstanding rather than fact. In truth, children with ADHD have the same intellectual potential as their peers. The condition affects attention and behaviour, not innate intelligence. 

What often confuses the issue is the impact ADHD can have on academic performance. These children may struggle with focus, organisation, or sitting still in a classroom. As a result, their grades may not always reflect their true learning potential or IQ. But when supported appropriately, they can thrive academically and socially. 

Why the Myth Persists 

Disrupted focus affects performance 

Children may find it hard to concentrate on tasks that don’t interest them, which can affect their school results. 

Behaviour masks ability 

Restlessness or impulsivity may distract from the child’s actual intelligence or ability to learn. 

Standard tests don’t fit all 

Traditional testing methods may not account for the unique ways in which children with ADHD process information. 

Misunderstood strengths 

These children often excel in creative, hands-on, or problem-solving tasks that aren’t always measured in typical assessments. 

Dismissing the ADHD and child intelligence myth helps ensure children receive support based on their true potential, not surface-level performance.
