Child and adult autism assessments London
Autism and ADHD testing in London
The Nook Neurodevelopmental Clinic is a leading private clinic specialising in ASD and Attention Deficit Hyperactivity Disorder (ADHD) assessments. Our clinicians provide a complete range of ASD and ADHD diagnostic evaluations so we can support children from five years upwards to adults. We operate from clinics in South Kensington & Farnham in Surrey.
We are a multidisciplinary team of professionals led by Dr Selina Warlow, a Clinical Psychologist with over 10 years of experience. Dr Warlow has worked in mental health services for the NHS and The Priory.
Neurodevelopmental conditions can have a profound effect on individuals and their families. Dr Warlow and her team aim to offer both diagnoses and support to adults and children and ensure that individuals and their families feel nurtured and supported through the assessment process.
Our diagnostic assessments follow best practice tools and guidelines set out by the National Institution for Health and Care Excellence (NICE), which is also used by the NHS.
Our team includes a multidisciplinary team which Dr Warlow leads, but also includes Clinical Psychologists, Speech and Language Therapists and Occupational Therapists.
For answers to common questions about the assessment process, please see our FAQs.
Our London clinic is based in South Kensington and is easily accessible by all public transport routes. We also have clinics in Farnham Surrey & Summertown Oxford.

Autism spectrum disorder diagnostic evaluation London
Our team uses the gold standard of autism screening and assessment tools. This allows us to quickly and accurately diagnose autism and put together tailored recommendations and support. Our process aims to be supportive and nurturing, and we seek to put people at ease during our assessment.
Our autism assessments consist of several stages to ensure we understand each individual’s strengths and areas where they may need additional support. The assessment includes sending out screening questionnaires to parents/carers and schools for child assessment, and these are sent directly to individuals for adult assessments. We will then arrange a time for an Autism Diagnosis Interview Revised (ADI-R) so we can gather information about you or your child’s behaviour and development over time.
We then complete a formal face-to-face assessment, called an ADOS-2, the gold standard for autism assessments. A multidisciplinary team completes this. We will then issue a detailed report and organise a feedback appointment to go through any recommendations and support and answer any questions you might have.
We are aware that some individuals may mask their difficulties, and this can be common in both women and girls, and behaviours can therefore be overlooked. Our team has a lot of experience diagnosing girls and women with ASD, and we can answer any questions about this.

London ADHD assessments for children and adults
Are you looking for an ADHD assessment for you or a child near London? Our clinic can also diagnose Attention-Deficit Hyperactivity Disorder (ADHD), both inattentive, hyperactive and impulsive and combined types (previously known as ADD).
We understand many people may be waiting for NHS assessments, and we want to ensure we can provide you or a child with quick and in-depth assessments so you can begin accessing support.
Our assessment process involves completing an in-depth developmental history using the ACE assessment tool. We will then meet you or your child to complete the QB Check, a computerised task used to assess hyperactivity, impulsivity, and inattention. We also used the Conners -4 screening tool to further assess for ADHD symptoms in children at school and at home.
The report you receive will include information, resources and recommendations for further support.

Pathological Demand Avoidance (PDA) assessments London
Some children and adults have a particular profile on the autism spectrum called Pathological Demand Avoidance (PDA).
Individuals with PDA experience significant levels of stress and anxiety and seek to maintain control to avoid demands placed on them.
While PDA does not appear separately in diagnostic manuals, such as ICD-10 or DSM-V, it has been formally recognised as a subtype of autism, which can be explored as part of the assessment process if necessary.
