Many parents know this feeling: their child is clearly bright, but school is a constant struggle. Missing assignments, can't sit still, always drifting into their own world. Does my child have ADHD — or is this just a phase?
If that question sounds familiar, you're not alone. ADHD is one of the most common neurodevelopmental conditions in Australian children, affecting an estimated 6–10%. Despite this, many children go years without a formal diagnosis — leaving families searching for answers and children carrying unfair labels.
The good news: we understand ADHD better than ever, and with the right support, outcomes can change significantly. The first step is knowing what to look for.
Your child might have ADHD if they:
- Struggle to stay focused on tasks that aren't immediately interesting
- Are frequently on the move — fidgeting, leaving their seat, or finding it hard to settle
- Have trouble controlling impulses or waiting their turn
- Have difficulty following multi-step instructions or completing tasks
- Show these behaviours consistently across both home and school
What Is ADHD in Children?
ADHD is a neurodevelopmental condition affecting attention, impulse control, and energy regulation. It has nothing to do with intelligence or effort — and it is not a reflection of parenting. Children with ADHD are often simply experiencing the world through a different neurological lens.
There are three presentations: inattentive, hyperactive-impulsive, and combined. ADHD also looks different from child to child — and notably, from boy to girl. Girls more commonly present with the inattentive type, which is frequently missed or misread as daydreaming, anxiety, or social withdrawal. If your daughter has been told she just needs to focus more, it may be worth looking closer.
Common Signs of ADHD in Children
The signs below can help you identify whether what you're observing aligns with known ADHD presentations. These are indicators — not a diagnosis. A formal assessment is the only way to know for certain.
Signs of Inattentive ADHD
- Difficulty sustaining focus on tasks that aren't urgent or immediately interesting
- Frequently loses everyday items — bags, pencils, homework
- Appears not to listen when spoken to directly
- Makes careless mistakes, even on familiar tasks
- Avoids or resists tasks requiring sustained mental effort
- Easily distracted by sounds, movement, or internal thoughts
Signs of Hyperactive / Impulsive ADHD
- Fidgets, taps, or leaves their seat when expected to stay still
- Talks excessively or interrupts conversations
- Acts before thinking — blurts out answers, takes risks without hesitation
- Has difficulty waiting their turn
- Seems constantly "on the go," even in quiet settings
Many of these signs can also appear in other conditions. Anxiety, autism, and learning disabilities can all produce similar patterns — which is exactly why a professional, comprehensive assessment matters.
When Should I Be Concerned?
It can be hard to know where typical developmental variation ends and something worth investigating begins. Three signals suggest it's time to seek an assessment:
- Symptoms are present consistently across multiple settings — most commonly both home and school
- They have persisted for six months or longer
- They are causing real functional impairment — academically, socially, or emotionally
Even if your child shows all three, it doesn't mean they definitely have ADHD. But it does mean a conversation with a psychologist is a sensible next step.
Could It Be Something Else?
Possibly — and a good assessment will account for this. ADHD frequently co-occurs with, or can be mistaken for, anxiety, autism, dyslexia, and sensory processing differences. A single label rarely tells the full story.
At ThinkAhead, our assessment looks at the complete picture — including any co-occurring conditions that may be shaping your child's experience. If autism or a learning difficulty is also a concern, our Autism Assessment Sydney and Cognitive Assessment Sydney pages outline what those processes involve and how they work alongside an ADHD assessment.
How Is ADHD Diagnosed in Children?
At ThinkAhead, our child ADHD assessment is thorough, evidence-based, and designed with both parent and child in mind. The process includes structured clinical interviews, standardised rating scales (including the Conners), cognitive testing, and questionnaires completed by both parents and teachers — followed by a dedicated feedback session and a detailed written report with findings and recommendations.
A GP or paediatrician referral may enable Medicare rebates under a Mental Health Care Plan. NDIS funding may also apply depending on your circumstances.

"A formal assessment doesn't just confirm or rule out ADHD — it gives you a complete picture of your child's strengths, challenges, and the support that will actually help."
If you recognise these signs, an ADHD assessment with ThinkAhead can provide the clarity and direction your family needs. No referral required. Clinics in Frenchs Forest and Meadowbank.
