Adult Autism & ADHD
Diagnostic Assessment

Our neuro-affirming Autism and ADHD assessments are available to adults aged 18+ across Australia via Telehealth. We take the time to understand your experiences, developmental history and individual strengths to explore whether you you meet the diagnostic criteria for Autism, ADHD or both (AuDHD).

Could Autism and ADHD explain your experiences?

You might consider a combined assessment if you experience a mixture of:

  • Difficulties with attention, organisation or time management
  • Sensory sensitivities or feeling easily overwhelmed
  • Social situations that require significant effort
  • A strong preference for routine alongside a need for novelty 
  • Periods of intense focus or changing interests
  • Masking or feeling like you’ve spent years trying to “fit in”.

You don’t need to know whether Autism, ADHD or both best explain your experiences before contacting us. That is what the assessment is designed to explore.

Post Assessment support

We can support you post assessment on an ongoing therapy basis to work through the outcome of your assessment (if you wish). 

Neurogrief is not uncommon with a late diagnosis of neurodivergence; in grieving the person you weren’t, the “what-if’s”, and the support you did not have access to.  You may find that you start re-experiencing memories that suddenly start to now make sense – for example; being overstimulated at events or social situations and not understanding unspoken rules.  

Please let us know if you would like to discuss how we can support you further.

Additional information

Whilst psychologists can diagnose Autism, and a diagnosis of Autism Level 2 or 3 may mean that you are eligible for support under the NDIS, this assessment only forms part of your NDIS application. 

Other assessments by other professionals (for example by an Occupational Therapist, Speech Therapist or a GP) are likely to be needed to have a diagnosis potentially accepted by the NDIA and funding provided by NDIS. There is no guarantee that you will receive NDIS funding.

If you are certain that you have ADHD and wish to trial medication, then we recommend that you go to a psychiatrist as they do their own assessment and prescribe medication. Psychologists are unable to prescribe medication.

Adult Autism & ADHD Assessment FAQ's

The pre-assessment pack requests clients’ complete forms and screening questionnaires for ADHD and/or Autism to gather information on your mental health. This allows time to be saved in your assessment appointment.

A 50% payment is required to secure your booking before the assessment session. The remainder is due before feedback session and report release.

Neurodiversity is the idea that differences in how people think, process information, and experience the world are a natural and valuable part of human variation. Rather than viewing Autism / ADHD as deficits, this perspective emphasies acceptance, strength-based understanding and support that honors individual differences.

Adults can live for many years without knowing they are neurodivergent. Seeking an assessment can be a transformative experience.

No. Medicare rebates do not apply to assessments.

Yes. This is a part of the diagnostic criteria for ADHD and/or Autism. Without this information, the outcome of your assessment may be affected. Please contact our team before booking if you would like to discuss this further.

No. Primary school reports can give information about ADHD related behaviours and your developmental history. We acknowledge that some people may not have access to these reports. As such, we will ask you to get two family members or friends (informants) to complete questionnaires and a person who knew you under the age of 18 to complete some questionnaires instead.

Please note: informants completing questionnaires on behalf of a client must be a person who was an adult at the time you were a child i.e. a parent, relative or family friend, or an older sibling.

The current healthcare system often has long wait times to see a psychiatrist. Psychologist can diagnose ADHD. A thorough assessment by a psychologist can shorten the diagnosis wait time. You will also receive a comprehensive report, feedback and personalised treatment recommendations for interventions.

No. Psychologist cannot prescribe medication. At present only psychiatrist can prescribe medication for ADHD (albeit there are plans to have GPs be trained in this area).  If you are sure you have ADHD and wish to trial stimulants we recommend you seek a referral to a psychiatrist via your GP.

Both psychologist and psychiatrists are trained in diagnosis. Psychologists focus on behavioural intervention for ADHD and psychiatrist pharmacology.

If you do not meet the diagnostic criteria for ADHD and/or Autism, you will be supplied with a summary detailing this and suggestions for further treatment.

Seeking assessment does not guarantee any diagnosis.

No. You are welcome to contact us by phone or email if you have any questions.

Yes. If you already have a diagnosis of one or the other, we can tailor the assessment to suit your needs.

This depends on the assessment. Our ADHD assessment is 1.5
hours; Autism 3 hours and combined 3-4 hours. We encourage movement breaks, fidget items, or other supports that may help you to feel as comfortable as possible
for the assessment session.
