When One Answer
Has Never Been
The Whole Story.
Autism and ADHD are the most commonly co-occurring neurodevelopmental conditions — yet they are routinely assessed separately, leaving families with a partial picture and clinicians working from incomplete maps. This assessment evaluates both, together, in one integrated clinical formulation.
If you’ve been told it’s “probably ADHD” and something still doesn’t fit — or if an autism diagnosis has never accounted for the attention and executive function challenges — this is the assessment designed to see the full picture at once.

Not all assessments result in a diagnosis — our goal is an honest, evidence-based clinical answer. Combined ASD + ADHD assessments are designed to clarify what is genuinely present, including ruling out conditions that may be mimicking either profile. Findings are documented in a single integrated written report and reviewed with you in a dedicated feedback session.
Why This Matters Clinically
ASD and ADHD co-occur in a significant proportion of individuals — yet they are frequently evaluated in isolation, leaving important diagnostic questions unanswered.
When assessed separately, clinicians often see only part of the picture. Attention difficulties can mask autistic traits. Sensory and social processing challenges can look like inattention. An integrated evaluation — using validated tools for both domains simultaneously — produces a single, coherent formulation that a sequential two-assessment approach may not.
Two Conditions. One Integrated Picture.
ASD and ADHD share surface presentations but have meaningfully different underpinnings. A combined evaluation does what two separate assessments cannot — it sees how they interact in this specific person.
Shared Surface. Different Roots.
Inattention, impulsivity, and executive function challenges appear in both conditions — but for different reasons. Treating them the same way produces inconsistent outcomes. An integrated assessment identifies which mechanism is driving what.
One Referral. One Report.
A combined assessment produces a single integrated report — not two documents that schools, physicians, and workplaces have to reconcile. The formulation speaks to both conditions together, with unified accommodation recommendations.
Recommendations That Actually Fit
Accommodation strategies for ADHD and autism overlap — but they diverge in important ways. When both are understood, the recommendations are tailored to the real profile, not a generic template for one condition.
Saves Time and Cost
Two separate assessments with two separate waiting lists can take years. A combined assessment is more time-efficient, more cost-effective, and produces a more complete clinical picture than sequential evaluations.
Masking Is Assessed Directly
Autistic masking can suppress visible ADHD symptoms in structured settings. ADHD can make autistic social patterns harder to distinguish. A trained clinician evaluating both simultaneously accounts for these interactions rather than being misled by them.
Schools Ask for Exactly This
Many Ontario school boards and post-secondary institutions now request documentation that addresses both attention and neurodevelopmental profiles in a single report. This assessment is structured to meet that standard.
The Overlap That
Changes Everything.
In clinical practice, ASD and ADHD rarely present as textbook versions of themselves when they co-occur. The picture is more nuanced — and more informative — than either condition alone would suggest.
Our clinicians are trained to hold both frameworks simultaneously and distinguish what belongs to each — so the report you receive reflects what is actually present, not what is most visible.
What ASD + ADHD Looks Like At Every Age
The combination presents differently across age groups — and the gap between what people see on the outside and what’s actually happening on the inside tends to grow over time.
Young children with both ASD and ADHD often present as intensely energetic in some moments and completely shut down in others. The combination can look different each day, making patterns hard to name.
Explosive reactions to transitions that feel both inflexible (ASD) and impulsive (ADHD) — impossible to predict from the outside
Deep, consuming interests — but the ability to shift attention when needed is minimal, and not for lack of trying
Social interactions that are genuinely confusing — not because of disinterest, but because the rules feel invisible and changing
Sensory sensitivities alongside hyperactivity — environments that are overwhelming also trigger restlessness, not calm
Prior assessment left you with a partial answer — one condition was identified, but the full picture still doesn’t fit
This is the age where the combined presentation often becomes impossible to manage quietly. Academic demand increases. Social complexity intensifies. And the strategies that sort-of worked in earlier years stop working.
Homework that takes hours — not because they’re not trying, but because starting, sustaining, and shifting tasks is genuinely difficult on multiple levels
Friendships that feel like work: social rules that shift unpredictably, and impulsive moments that damage relationships they care about
Teachers see one child. Parents see another. Neither picture is wrong — but neither is complete.
Anxiety that has become a constant background — driven partly by social uncertainty (ASD) and partly by performance gaps (ADHD)
A prior ADHD or ASD diagnosis helped somewhat — but not enough, because the other piece was never formally identified
Teenagers with both ASD and ADHD often experience compounding burnout — the autistic exhaustion of masking meets the ADHD dysregulation of not being able to regulate the response to that exhaustion.
They’ve done their own research — autism, ADHD, both — and what they’re finding resonates, but they want a real clinical answer, not a self-identification
School is survived, not experienced. The effort required to manage the environment leaves nothing for the actual work.
Emotional regulation has become the dominant challenge — storms arrive fast, last long, and are genuinely hard to recover from
Social withdrawal increasing — not from disinterest, but from a real cost-benefit calculation about energy and outcome
One diagnosis was given and one piece of the puzzle was addressed. The rest was left unnamed.
Many adults with both conditions developed elaborate coping systems that worked — until they didn’t. A combined adult assessment is often the first time someone receives a coherent explanation for a lifetime of experiences.
You’ve been told it’s anxiety, or depression, or “just stress” — but none of those explanations have ever quite fit what you actually experience
Work, relationships, and daily functioning require a level of effort that other people don’t seem to need — and the gap has been growing
One diagnosis was given at some point — ADHD in childhood, or an autism identification in adulthood — but it explained only part of what you experience
You want a single thorough evaluation that looks at everything together — not two separate referrals with a year between them
You need documentation for workplace accommodations, HR processes, or disability support that reflects the full clinical picture
Both Domains.
One Formulation.
Our clinicians are trained in both neurodevelopmental frameworks simultaneously. We use validated tools from both domains, evaluated by a single clinician who holds the full picture throughout — so the report you receive reflects how the conditions interact, not just whether each one is present in isolation.
Validated Tools from Both Domains
ASD assessment uses ADOS-2 and ADI-R where indicated. ADHD assessment uses CPT-3, CAARS, and BRIEF-2. Both are administered and interpreted by the same clinician, producing a single integrated formulation.
Differential Diagnosis Across Both Conditions
We look for what is genuinely present — including anxiety, mood, and learning differences that may be driving what appears to be ASD or ADHD. Clarity is the goal, not a predetermined answer. Not all assessments result in a diagnosis.
One Report. Multiple Uses.
The integrated report is structured for direct use by schools, physicians, workplaces, and post-secondary accommodation offices. One document covers both conditions, with unified accommodation recommendations that reflect how they interact.
Your Teen Gets Their Own Feedback Session
For teens aged 12 and up, we offer a private feedback session — a dedicated space where your teenager hears directly from their clinician what was found in both domains, in language built for them, not for a school file. Understanding yourself changes how you approach everything. Delivered in accordance with Ontario consent and confidentiality standards.
We See You in Your Real Environment
Sensory, attentional, and social challenges often present differently in familiar environments than in a clinical office. Virtual-first delivery means we observe individuals where the challenges actually occur — at home, in their space, during real routines.
Clinically Driven Delivery: Assessment methods are selected based on age, presentation, and clinical appropriateness, and are administered in accordance with professional standards and standardized administration requirements.
Neurodiversity-Affirming: We approach both autism and ADHD as differences in how the brain processes the world — not deficits to be corrected. Our goal is understanding, and a set of recommendations that fits this person’s actual life.
Choosing the Right Level of Depth
The right pathway depends on your specific question, your child’s or your own history, and what the report needs to accomplish. If you’re unsure, our free Guidance Call is the right place to start.

If anxiety, mood, or learning differences also need to be evaluated — that is a different scope of assessment.
When co-occurring conditions like anxiety, depression, or learning disabilities need to be formally assessed alongside ASD and ADHD, the right path is one of our broader integrated assessments — not an add-on tier. This keeps the formulation coherent and the report defensible. See the ASD + ADHD + Learning Disability assessment or speak to your clinician on your Guidance Call about the right scope for your situation.
