What Behavioral Issues Are Typical in Children with ADHD Combined Type? 

ADHD Combined Type is a presentation of attention deficit hyperactivity disorder where a child shows both inattentive and hyperactive-impulsive traits. This means they struggle to concentrate, stay focused, control impulses, and remain seated. These tendencies appear in social, family, and school settings, making them easier to spot but sometimes harder to manage. 

Common Behavioural Traits in Combined Type ADHD 

Inattentive Behaviours 

Children with ADHD Combined Type may: 

• Frequently misplace schoolbooks, pencils, or personal belongings 

• Struggle to follow directions or complete tasks 

• Forget daily routines, such as getting dressed or packing their bag 

• Appear forgetful even when spoken to directly 

These behaviours can look like carelessness but are often due to attention challenges. 

Hyperactive-Impulsive Behaviours 

You might also notice: 

• Talk excessively, even when it is not appropriate 

• Interrupting conversations or giving answers without thinking 

• Act impulsively, such as grabbing items without asking or leaving unexpectedly 

• Constantly tap, fidget, or leave their seat 

These behavioural issues are typical in children with ADHD Combined Type and can be particularly challenging in structured environments such as classrooms. 

Why These Behaviours Happen 

The behaviours listed above are not simply down to a child being difficult or defiant. ADHD affects executive functions such as planning, impulse control, attention, and emotional regulation. These brain functions develop differently in children with ADHD Combined Type. Because of these brain differences, they may find it hard to sit still, listen, or follow instructions even when they genuinely want to. Understanding this encourages empathy rather than frustration. 

What Can Help at Home and School? 

Supportive strategies can go a long way in managing behavioural issues: 

• Visual reminders and structured routines help children know what’s expected 

• Movement breaks or discreet fidget tools provide an outlet without disruption 

• Clear, calm instructions spoken one at a time are more effective than lengthy explanations 

• Positive reinforcement, such as sticker charts or praise for effort, encourages progress 

• Teamwork between parents and teachers ensures consistency across environments 

With the right tools and understanding, children with ADHD can thrive.
