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.

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.

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 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...

I tried Concerta 38mg as part of my ADHD treatment, but unfortunately, it wasn’t the right fit for me. Despite not being able to continue the full course of treatment due to financial reasons, Dr. Pav was incredibly understanding and supportive. He advised me free of charge and kindly arranged to transfer my care agreement to my GP at no additional cost. If I decide to return to a private clinic in the future to continue managing my ADHD, I would 100% choose to work with Dr. Pav again

I am very pleased with my experience with the clinic. I had gone through another assessment a few months prior with a private psychiatrist and felt very diminished. They did not listened to what I had to say and assumed things based on a couple sentence about my life. I found private adhd through an ad and thought to give it a try. And I'm so happy I did. The lady I spoke to, Angel, is lovely and so helpful. She was extremely available even though I felt like messaging her a bit too...

His deep understanding of the unique challenges that come with ADHD is evident in every interaction and his support extends beyond just medical treatment - for eg. he routinely discusses and offers practical strategies to manage daily life. He takes the time to understand each patient’s individual needs and provides tailored advice that makes a real difference.
