Adult ADHD & Autism Assessments
Assessments that empower and illuminate.
A trauma-informed, neuroaffirming assessment process where your lived experience is taken seriously.
We help you make sense of what has been happening, understand your patterns with more compassion, and identify practical next steps you can use in real life.
A calm place to start
For many people, the hardest part is starting.
You might feel overwhelmed, doubtful, or exhausted from years of pushing through. We slow it down, listen carefully, and build a clear picture with you at a pace that makes sense.
Many adults seek assessment because something is not adding up. You may want clarity, language for your experience, documentation, or guidance about what to do next. Most people want understanding that leads to real change.
This may be for you if:
you have spent years masking, coping, or people-pleasing
you’re often told you seem “fine” while privately struggling
burnout, shutdown, overwhelm, anxiety or depression keep returning
bills, emails, tasks, work or study demands feel harder than they should
you’ve tried support before but still feel unclear about what is really going on
you suspect ADHD, autism, or both
you want more than a “yes/no” answer
you want practical recommendations that fit how you actually function
Our special focus: complex adult presentations
Does this story sound familiar?
Years of masking, burnout, trauma, or being told you are “fine” while nobody realises how much you are privately struggling.
Bills get missed. Email inboxes pile up. Projects stay unfinished. Future demands feel unbearable. You might find yourself scrolling, procrastinating, or getting stuck in looping thoughts that say you have to keep pushing through, or people will be disappointed, frustrated, or leave.
This can show up everywhere: school, work, study, relationships, home life. You feel worse over time, the demands keep coming, and there never seems to be enough energy to do what life requires.
You might have tried support or medication for anxiety or depression, but still feel flat, overwhelmed, or no clearer about what is really going on. Some days, it is hard to get out of bed.

This is where our approach is often most helpful.
We often see that capable, caring, high-effort people are especially vulnerable to autistic burnout, and that burnout can look like anxiety or depression when the neurodevelopmental picture has been missed.
We work carefully with complex and overlapping presentations, including ADHD and autism, anxiety and depression, learning differences such as dyslexia or dysgraphia, trauma, and substance use or other addictions.
Once we understand how your system fits together, we can help you adjust your supports and daily structure to protect your energy, lean into your strengths, and get the right help in the places it will matter most.
What makes our assessments different
-
We consider internal experience, compensatory strategies and the cost of coping, not only what others can see.
-
We do not reduce people to paperwork. We aim to understand the person behind the report.
-
Our assessments use structured interviews, screening tools and clinical formulation. Adult ASD assessments include ADOS-2 Module 4.
-
You receive clear diagnostic reasoning and recommendations for work, relationships, wellbeing, support planning and daily life.
-
With your consent, we can liaise with your GP, psychiatrist or treating providers where helpful.

ADHD assessment pathways
There is more than one way to pursue an adult ADHD diagnosis and medication in Western Australia.
-
your main goal is a medication trial
your presentation feels straightforward
your mental health is relatively stable
you have a clear history of childhood symptoms and current functional impact
-
the picture feels complex
trauma, burnout, anxiety, depression, sleep disruption or emotional dysregulation are present
you are high-masking or have spent years compensating
you have been dismissed or misdiagnosed in the past
you suspect autism as well as ADHD
you want practical recommendations alongside diagnostic clarification
Not sure which pathway fits? If you enquire, we can help you consider the most suitable, efficient and safe next step.

We do not reduce people to paperwork.
Our assessments aim to be clinically robust while still honouring the person behind the report. We are trauma-informed, neuroaffirming, masking-aware and focused on practical recommendations that support real-life outcomes.
We often see people’s eyes light up when they realise they were given the wrong manual for their system, and they thought the problem was them.
Our work helps you update that manual, recover from burnout, rebuild self-trust and move forward with more clarity and confidence.

-
These assessments are for adults seeking clearer understanding of ADHD and/or autistic patterns, diagnostic clarity where appropriate, and practical recommendations for support.
Some people also need documentation to support planning, workplace adjustments, study needs, treatment planning, or other support pathways.
-
Medicare rebates may be available depending on the clinician you see and the referral pathway used, such as a Mental Health Treatment Plan or Chronic Disease Management Plan.
If you are unsure, please ask us before booking and we can clarify what may apply in your situation.
-
We take masking seriously.
We explore internal experience, compensatory strategies, burnout patterns, and the cost of coping alongside observable functioning. Many capable adults have been missed because they learned to hide how much effort life was taking.
-
This worry is common.
We consider patterns over time, including the effort it takes to function, not only what others can see. If a full assessment is unlikely to be useful, we will not pressure you to proceed.
-
For many adults, yes.
Understanding your neurotype can reduce self-blame, make past patterns make sense, and support better decisions about work, relationships, energy, wellbeing and support needs. If you are unsure, we are happy to talk it through with you.
-
For us, trauma-informed care is the front door. It means safety, pacing, respect, and careful attention to what a person has had to survive.
Our approach is also neuroaffirming. That means we treat you as the expert in your own life and recognise that your efforts, values, strengths and coping patterns may have been organised around survival rather than around ease.
We work with you to gently challenge harmful narratives such as “lazy”, “broken” or “unmotivated”, and to build a more accurate manual for how your system works.
-
Our process is thorough, paced and whole-of-person.
We consider the factors that shape your day-to-day experience, including masking, burnout, environment, relationships, work or study demands, psychological wellbeing and functional impact. The goal is not only diagnostic clarity. The goal is practical understanding that supports real-life change.
