ADHD Assessment · Children & Teens · North York & Oakville
Answering the question of ADHD fully.
When families come to us wondering if their child has ADHD, they are usually carrying more than one question. Is this ADHD or something else? Is it both? What does this mean for school, for home, for who my child understands themselves to be?
We are here to hold all of those questions. At Whole Kids Health, our ADHD assessments are comprehensive, strength-based, and designed to give your family a full picture, not just a label. North York, Oakville, and across Ontario.
Understanding ADHD
ADHD is about how the brain regulates. Not willpower.
As human beings, we regulate three things: our attention, our behaviour, and our emotions. Children with ADHD have brains that regulate differently. That is not a reflection of how much they care, how hard they try, or how capable they are.Regulating attention
Where attention goes, how long it stays, and how easily it shifts. This is why the same child who cannot focus on homework can lose themselves completely in something that genuinely interests them.
Regulating behaviour
Acting before thinking, difficulty waiting, impulsivity. Or the quieter version: spending so much energy holding it together on the outside that everything else quietly suffers.
Regulating emotion
Big feelings that arrive fast and are hard to bring back down. Frustration, rejection sensitivity, emotional flooding. This part is often the hardest on families, and the most frequently missed.
A comprehensive assessment sees the whole child.
What the assessment covers
Our ADHD assessment is built on the same three-pillar psychoeducational foundation as all our assessments, with additional ADHD-specific components layered in. Every piece of information we gather is considered together, across home, school, and the broader context of your child's life.Step 01
Cognitive testing
How your child thinks and reasons. This includes the ability to take in and process new information, hold things in working memory, plan and organize, and shift between ideas.
Step 02
Learning and academic testing
Reading, writing, spelling, math, and oral language. We look at where your child's academic skills are and how attention is affecting learning specifically.
Step 03
Socio-emotional testing
Questionnaires and clinical interviewing covering anxiety, mood, self-esteem, and peer relationships. ADHD rarely travels alone, and this piece tells us what else may be present.
Step 04
Document review and interviews
Report cards, previous assessments, and conversations with parents, teachers, tutors, and therapists who know your child well.
Step 05
Written report
A clinical formulation with findings, any relevant diagnoses, and specific recommendations you can share with school and care providers.
Step 06
Feedback session
A dedicated appointment to walk through the results together, answer questions, and make sure the recommendations are workable for your family.
Executive functions are the CEO of the brain. And sometimes that CEO needs support.
Executive Functioning
One of the core pieces of the ADHD picture is executive functioning. These are the skills that help a child plan, start, organise, and follow through. Think of the brain as a company. You can have excellent workers in every department. But without a strong CEO directing them, the whole operation struggles to get going. Executive functions are the CEO of the brain. When the brain regulates differently, these skills can be harder to access, and that shows up in very specific ways at home and at school.
Knowing how to start a task
Keeping attention on something over time
Breaking a big task into manageable steps
Organising materials, time, and thoughts
Holding information in mind while using it
Managing frustration and emotional responses in the moment
What this looks like in real life
"They always forget their water bottle."
"Homework takes four times as long as it should."
"Their backpack is always a disaster."
"They focus perfectly on video games. Just not on anything else."
"They rush through everything and never want to fix it."
"They know what to do. They just cannot seem to start."
The video game focus is one of the most misunderstood things we see. ADHD is not an inability to focus. It is a difficulty regulating where attention goes, and for how long. High-stimulation tasks pull attention automatically. That is a very different thing than not caring.
When ADHD gets missed
Every child deserves to be understood for exactly how their brain works.
Most people picture ADHD as the child who cannot sit still, full of energy and always on the go. And that child exists. But ADHD shows up in quieter ways too, ones that are much easier to miss.The inattentive profile
Present in the room. Somewhere else in their mind.
This child is often described as a daydreamer, someone who just needs to focus more, or a kid who is bright but not working to their potential. What is actually happening is that their brain is working hard in a different direction. The support they need has simply not been found yet.
ADHD in girls
Capable, creative, and quietly exhausted.
Girls with ADHD are often some of the most capable, creative, and socially attuned kids in the room. That capacity is real. It is also part of why they are missed. When you are good at holding it together, the people around you often believe you are fine. A comprehensive assessment sees what even the most resilient kids cannot always show.
