Combined Autism and ADHD Assessment for Adolescents and Adults

What a Combined Autism and ADHD Assessment Involves

This integrated approach reduces misdiagnosis and strengthens diagnostic accuracy.

Assessments are aligned with DSM-5-TR criteria and current Australian best-practice standards. They are suitable for personal clarity, workplace accommodations, university support, NDIS documentation where relevant, and referral to medical practitioners for medication discussion if appropriate.

This approach is particularly valuable for individuals with subtle or masked presentations who may not fit outdated stereotypes.

For condition-specific information, you can read about the Autism assessment process or the ADHD assessment process.

The Assessment Process

The process includes:

  • Comprehensive developmental questionnaires
  • A structured diagnostic interview
  • Detailed clinical analysis and report writing
  • A personalised feedback session with recommendations

This assessment is particularly valuable for adults seeking later-life diagnosis, where overlapping traits may previously have been overlooked.

Comprehensive Developmental Exploration

The assessment begins with detailed standardised questionnaires and developmental history measures. These explore early childhood development, communication patterns, attention regulation, executive functioning, sensory experiences and daily functioning.

This structured information allows identification of patterns over time, not only current concerns. It ensures the diagnostic session is focused, informed and clinically grounded.

Structured Diagnostic Interview

During the extended diagnostic session, I use validated clinical interview frameworks aligned with DSM-5-TR criteria.

Assessments incorporate structured diagnostic interviews and contemporary tools, including the MIGDAS approach, supporting nuanced understanding of Autism, particularly in individuals who mask or camouflage traits.

We explore social communication, cognitive flexibility, emotional regulation, attentional patterns, impulsivity, masking behaviours and functional impact across settings.

This is a formal clinical assessment – not a checklist conversation.

Formal Diagnostic Report

Following the assessment, you receive a comprehensive written diagnostic report. This outlines diagnostic criteria considered, evidence supporting conclusions, differential considerations and functional impacts.

Reports are suitable for educational institutions, workplaces, NDIS documentation where relevant, and referral to medical practitioners if appropriate.

The report is clinically robust and clearly written.

Individualised Feedback and Recommendations

In your feedback session, we review findings in detail. I explain how diagnostic criteria were met or not met and answer your questions.

You receive practical, individualised recommendations tailored to strengths, support needs and life context. This may include educational adjustments, workplace accommodations or referral pathways.

Appointments are available in Darwin and via telehealth across Australia.
