Your child isn't defiant. They're not lazy. And they're definitely not "doing it on purpose." They may just have a brain that works differently — and one that desperately needs to be understood.
If you've watched your child struggle through school, meltdowns, forgotten homework, and friendships that keep falling apart — while being told they just need more discipline or better effort — this is for you.
ADHD (Attention-Deficit/Hyperactivity Disorder) is one of the most common neurodevelopmental conditions in children and adolescents, affecting an estimated 5–9% of Canadian youth. Yet it remains one of the most misunderstood — especially when it looks different from the classic "bouncing-off-walls" stereotype.
At Théla Psychotherapy in Markham, we work with children, teens, and the families navigating life with ADHD. This post is for every parent who has ever thought: something is going on, but I can't quite name it.
ADHD in Youth: It Doesn't Always Look Like Hyperactivity
ADHD presents across three types, according to the American Psychiatric Association's DSM-5: Predominantly Inattentive, Predominantly Hyperactive-Impulsive, and Combined. The hyperactive subtype is the one most people recognize — but the inattentive subtype is frequently missed, especially in girls, gifted children, and kids from cultures where quiet compliance is expected.
Inattentive signs — daydreaming, losing belongings, difficulty following multi-step instructions, forgetting to hand in completed work, losing track of conversations.
Hyperactive-Impulsive signs — interrupting, difficulty waiting their turn, restlessness, talking excessively, impulsive decision-making without considering consequences.
Combined presentation — many children show both, often shifting in which symptoms are more prominent depending on age, setting, and stress level.
In girls specifically, ADHD tends to look quieter: excessive daydreaming, people-pleasing, anxiety, and social difficulties rather than disruptive classroom behaviour. This is why girls are diagnosed significantly later than boys — often not until adolescence or adulthood, after years of quietly struggling.
The School Experience: Why "Try Harder" Doesn't Work
For a child with ADHD, school is often an exercise in sustained frustration. Executive function — the set of cognitive skills that govern planning, organization, task initiation, and working memory — is neurologically impaired in ADHD, not just underdeveloped. Telling a child with ADHD to "just focus" is like telling a child with a broken arm to "just lift more."
What you may see at home after school: emotional collapse, refusal to do homework, rage over seemingly small things, and an exhausted child who held it together all day and simply has nothing left. This is sometimes called the After-School Restraint Collapse — and it's a sign your child is working extremely hard just to cope.
ADHD and the Emotional Layer: What Gets Overlooked
One of the most underappreciated features of ADHD is emotional dysregulation — and it matters enormously for children and teens.
Research from Dr. Russell Barkley, one of the world's leading ADHD researchers, shows that children with ADHD have significantly more difficulty managing emotional reactions — not because they don't care or aren't trying, but because the same neurological circuits governing attention also regulate emotional response.
This shows up as:
- Intense reactions to disappointment, transitions, or perceived unfairness
- Rejection Sensitive Dysphoria (RSD) — deep, acute pain when criticized or left out
- Difficulty calming down once escalated
- Big emotions that "don't match" the situation, from a neurotypical lens
This emotional dimension is also why anxiety and ADHD so frequently co-occur — up to 50% of children with ADHD also have an anxiety disorder. Many kids develop anxiety as a secondary response to years of failures, social rejection, and feeling "wrong" in environments that weren't built for their brains.
Got it — I can see the full Jane booking page. The free consultation link is https://thela.janeapp.com/#/staff_member/1/treatment/13 and there's also a Youth & Family Services booking path. I'll use both strategically.

A Note for Families from Cultural Communities
Cultural context shapes how ADHD is seen — and whether it gets named at all.
In many East Asian, South Asian, and immigrant families, academic performance is central to family identity, and behavioural challenges may be interpreted through a lens of disrespect, insufficient effort, or poor parenting. Children may be pushed harder, shamed more, or quietly watched while their struggles go unnamed.
This doesn't reflect bad parenting. It reflects a mismatch between cultural frameworks and neurodevelopmental realities — one we see often in our work with GTA families. A child who is struggling is not a child who is failing their family. They are a child who needs their family to understand their brain.
At Théla, our services are available in English, Mandarin, Cantonese, and Portuguese, and we bring a culturally sensitive lens to every conversation with families navigating these intersections.
What Actually Helps: Treatment Options for Youth ADHD
Clinical guidelines for youth ADHD from the Canadian Paediatric Society recommend a multimodal approach combining behavioural support, school accommodations, family involvement, and where appropriate, medication.
Psychotherapy for the child or teen For children 6 and up, CBT adapted for ADHD addresses avoidance, negative self-talk, and study and organization strategies. For teens, therapy also supports identity — adolescence is already a time of profound self-questioning, and carrying a shame-laden relationship with your brain makes that harder. Therapy offers a space to understand the diagnosis, build self-advocacy, and separate "I have ADHD" from "I am broken."
Parent coaching and education Parents are often the most powerful intervention. Parent training in behaviour management — learning how to structure the environment, reduce friction, respond to dysregulation effectively, and advocate at school — is among the most evidence-based treatments for childhood ADHD, particularly for younger children. At Théla, we offer Parent Consultation & Coaching specifically for this purpose.
School accommodations Individual Education Plans (IEPs) and Identification, Placement, and Review Committees (IPRCs) are available through Ontario school boards. A psychoeducational assessment is often the gateway to formal accommodations — extended time, reduced-distraction environments, chunked assignments, and modified assessment.
Medication Stimulant medications are among the most well-studied treatments in all of paediatric medicine. For many children, medication meaningfully improves focus, impulse control, and emotional regulation — and when combined with therapy and parent coaching, outcomes are strongest. Medication decisions are made with your child's paediatrician or psychiatrist.
Canine-Assisted Therapy with Emma & Evee For anxious or dysregulated youth, our therapy dogs Emma (Bernese Mountain Dog) and Evee (Bernedoodle) are available in in-person sessions. Research supports the use of animal-assisted therapy in reducing anxiety, improving attention, and creating a sense of safety that makes therapeutic work more accessible for children and teens.
What You Can Do Right Now
You don't need a diagnosis in hand to begin. You need a clinician willing to listen, hold the complexity, and work alongside you.
Some of the most important things parents can offer their child with ADHD are simple but profound: believing them when they say they tried, reducing shame in how the diagnosis is discussed at home, and becoming a vocal advocate in every system your child navigates.
Your child's ADHD is not a parenting failure. It is a neurological reality that, with the right support, does not have to define their ceiling — only the kind of support they deserve.
Your child deserves support that actually fits their brain. Théla Psychotherapy offers youth therapy (ages 12–17), parent coaching, and canine-assisted sessions in Markham — in English, Mandarin, and Cantonese. Book a Free 15-Minute Consultation →
