ADHD Symptoms in Children: Signs Parents Should Know
7 min read
Recognising ADHD in children is not always straightforward. All children can be inattentive, impulsive, or hyperactive at times. ADHD is distinguished by the pervasiveness, frequency, and functional impact of these behaviours across multiple settings.
Core symptom clusters
ADHD in children is grouped into three presentations: Predominantly Inattentive (difficulty focusing, following instructions, completing tasks), Predominantly Hyperactive-Impulsive (restlessness, interrupting, difficulty waiting), and Combined (significant symptoms in both clusters). The Combined presentation is most common in school-age children.
Inattention in children
Makes careless mistakes in schoolwork; has difficulty sustaining attention during play or lessons; appears not to listen when spoken to directly; fails to finish homework or chores; has trouble organising tasks; avoids activities requiring sustained mental effort; frequently loses pencils, books, and belongings; is easily distracted by external stimuli.
Hyperactivity and impulsivity
Fidgets or squirms constantly; leaves seat when expected to remain seated; runs or climbs in inappropriate situations; unable to play quietly; on the go as if driven by a motor; talks excessively; blurts out answers before questions are finished; difficulty waiting for a turn; frequently interrupts or intrudes on others.
ADHD at school
ADHD significantly impacts academic performance — not because of reduced intelligence but due to executive function deficits. Children with ADHD may struggle to copy from the board, maintain attention during whole-class instruction, manage homework independently, and regulate behaviour during unstructured time.
