What are Autism Spectrum Disorders (ASD)?

Autism spectrum disorder assessment is essential for individuals experiencing challenges with social interactions, communication, and behaviour. Autism spectrum disorders include conditions such as Autistic Disorder, Asperger’s Syndrome, and Pervasive Developmental Disorder (NOS). Early private autism evaluation can provide clarity and access to appropriate interventions.

What is Asperger's Syndrome?

Asperger’s Syndrome is a form of high-functioning autism that affects social interactions and communication. Individuals with Asperger’s may exhibit high intelligence, strong subject interests, and strict routines. Our private autism assessment cost includes thorough Asperger’s testing to provide a precise diagnosis and support plan.


These are some of the common Autism symptoms you or your child may be experiencing on a day-to-day basis.

Our ASD Services in London

We offer a comprehensive ASD service, providing thorough assessment and expert management for all autism spectrum disorders. Our service is designed to support children, adolescents, and adults, delivered by experienced psychiatrists and psychologists with extensive expertise in autism care.

The process begins with an initial assessment by our medical specialists, incorporating a gold-standard diagnostic interview to evaluate how ASD affects daily life.

To confirm the diagnosis, we use a series of online questionnaires, completed by you—or in the case of a child, by parents and teachers. This allows us to collect objective, reliable data to establish a baseline and measure ASD symptoms accurately. If ASD is diagnosed, this data becomes a valuable tool in monitoring progress, assessing treatment effectiveness, and making adjustments when necessary.

We understand that an ASD diagnosis can be a significant moment for you and your family. Our consultant psychiatrists and paediatricians will guide you through the next steps, offering tailored support and management strategies to help navigate the future with confidence.

How We Diagnose Autism

We understand that medical assessments can feel overwhelming, but there’s no need to worry—our autism assessment is a straightforward and supportive process. No health or blood tests are required. Instead, our specialists focus on observing how you interact socially and communicate with others. We also explore your childhood development and any mental health challenges you may have experienced.

To ensure a thorough and accurate diagnosis, we use a range of validated diagnostic tools, including:

  • Autism Diagnostic Observation Schedule (ADOS) – for children
  • School Report – for children
  • Autism Diagnostic Interview-Revised (ADI-R) & Client Questionnaire
  • AQ-10 – Autism Spectrum Quotient screening tool
  • AQ-50 – Self-assessment questionnaire measuring autism-related traits
  • EQ-40 – Empathy Quotient self-report measure
  • RAADS-R – Ritvo Autism Asperger Diagnostic Scale – Revised
  • Relative Questionnaire – gathering insights from close family members
  • GAD-7 – Generalised Anxiety Disorder assessment (7-item scale)
  • PHQ-9 – Patient Health Questionnaire (9-item scale for depression severity and treatment response)

Following the assessment, your results will be carefully evaluated against the diagnostic criteria outlined in the International Classification of Diseases (ICD-10) and the National Institute for Health and Care Excellence (NICE) guidelines. These internationally recognised frameworks, including the DSM-IV criteria, ensure a precise and reliable diagnosis of ASD and Asperger’s syndrome.

I had a great experience with PrivateADHD. Angel made the booking process quick and easy, and I got my assessment and diagnosis on the same day. Angel was incredibly helpful and kind—she really put me at ease and answered all of my questions. Dr Pav was also brilliant: calm, professional, and easy to talk to.

I’m so grateful I found Dr. Pav and Private ADHD through a friend who told me about it and convinced me to get tested for ADHD. For the first time in a long time, I felt like someone actually listened and took the time to understand what I was going through. Dr. Pav walked me through the entire ADHD assessment and helped me make sense of everything I’d been feeling for years. I’ve been struggling ever since I can remember. My parents didn’t understand its hard for me to do certain things

I first met with Dr Kooner about my daughter who had already been diagnosed with ADHD but I just couldn't find anyone who could prescribe. Dr Kooner spent a long time explaining that the person prescribing has to be the one that had performed the assessment. He kindly repeated the assessment efficiently & at a reasonable fee, arriving at the same diagnosis of my daughter with ADHD. Since then his management of her care has been absolutely second to none. We meet every 3 weeks...
