Private Autism Diagnosis and Support Services

At AuDHD Psychiatry,

We provide private autism assessments to help individuals and families gain clarity, answers, and access to tailored support.

Our experienced clinicians use gold-standard tools and a compassionate approach to deliver accurate diagnostic and post-assessment care for adults.

Understanding the ADHD Diagnostic Process

An ADHD assessment combines screening tools and clinical evaluations to identify symptoms and provide a clear diagnosis.

How Does the ADHD Diagnosis Process Work?

Here’s how we build an accurate picture of your challenges:

ADHD Screening Tools

We use clinically approved ADHD screening questionnaires to identify symptoms and patterns.

1:1 Diagnostic Interview

These structured conversations explore your developmental history, lifestyle, and daily functioning.

Information Gathering

You’ll provide context through forms or reports (e.g. school or work history) to support a comprehensive evaluation.

Symptom Analysis

We assess both inattentive and hyperactive traits, helping to rule out other conditions and give a clear picture.

How Does the ADHD Diagnosis Process Work?

A high-quality ADHD assessment is about understanding your brain, validating your experience, and getting the right support.

    Work, Academic, and Developmental History Review

    We look at your past experiences in school, work, and relationships to identify patterns consistent with ADHD across your lifespan.

    Rule-Out Screening for Other Conditions

    To ensure an accurate diagnosis, we may screen for other mental health conditions that can mimic or co-occur with ADHD (e.g. anxiety, autism, or trauma).

    Symptom Impact & Functional Assessment

Psychological vs Psychiatric ADHD Testing

ADHD assessments take more than a single test, and not all clinicians approach it the same way.

Here’s how psychological and psychiatric ADHD testing differ, and why choosing a clinic that offers both ensures a complete, accurate diagnosis.

Psychological ADHD Testing

Psychiatric ADHD Testing

Conducted by: Clinical or counselling psychologists

Conducted by: Medical doctors (psychiatrists) specialising in ADHD

Focuses on: Cognitive, emotional, and behavioural patterns

Focuses on: Medical history, symptom profile, and medication suitability

Tools used: Self-report questionnaires, cognitive assessments, structured interviews

Tools used: Diagnostic interview, clinical ADHD evaluation, medication trial, where appropriate

Ideal for: Understanding how ADHD affects learning, emotions, and everyday functioning

Ideal for: Adults seeking both diagnosis and ongoing treatment

Common in: School and university assessments, especially for children and young adults

Common in: Private ADHD clinics and medication-based treatment plans

Why Choose Us?

AuDHD Psychiatry brings both expertise areas together. Our multidisciplinary team includes ADHD psychiatrists, psychologists, and prescribing specialists.

If you meet the criteria, you’ll get diagnosed with ADHD using methods that are grounded in both psychological insight and medical evaluation.

Plus, you’ll get fast access to treatment when needed.

ADHD Assessment: How It Works

Your diagnosis starts by choosing a qualified ADHD diagnosis doctor. At AuDHD Psychiatry, all assessments are conducted by clinicians with experience in adult ADHD and neurodivergent care.

You don’t need a GP – self-referrals are welcome.

Before your appointment, you’ll be asked to complete validated screening tools that explore ADHD symptoms in adults.

You’ll also be guided on how to prepare notes about your personal, academic, and work history.

During your session, a specialist will explore your current challenges, background, and symptom presentation using structured diagnostic interviews.

This process is designed to be collaborative, clear, and non-judgmental. Appointments typically last 90–120 minutes and can be done remotely.

If you meet the criteria for ADHD, you’ll receive a written diagnostic report within days.

This includes:

  • Formal diagnosis
  • Recommendations for treatment, workplace adjustments, or university support
  • Optional follow-up appointments for treatment

Costs and Benefits of Private ASD Assessments

At AuDHD Psychiatry, we understand that choosing a private assessment is an important decision.

Mental Fatigue from Masking

Mental Fatigue from Masking

Constantly trying to “fit in” can be exhausting. Many adults unconsciously mask their natural behaviours, which can lead to burnout, anxiety, or a sense of disconnect.

Need for Routine and Predictability

Need for Routine and Predictability

Sudden changes or unclear plans can feel overwhelming. Having predictable routines helps reduce stress and creates a sense of safety.

Challenges in Social Settings

Challenges in Social Settings

Small talk, group conversations, or picking up on non-verbal cues can feel confusing or draining — even with people they know well.

Sensory Sensitivities

Sensory Sensitivities

Everyday environments — like supermarkets, offices, or public transport — might feel too loud, too bright, or simply too much.

Deep Interests and Focus

Deep Interests and Focus

Despite the challenges, understanding autism can bring a powerful sense of self-awareness and relief. A diagnosis isn’t about labelling — it’s about clarity, self-compassion, and finding the right support.
