Katherine Goodsell Bio

Why Choose ADHD Health Clinic for Your Child’s Combined Assessment?

Autism and ADHD frequently coexist in childhood and adolescence. Our pathway is purpose-built for ages 6–17 and evaluates both conditions together, so you avoid repeated appointments and receive one coherent outcome.

Your assessment is delivered by highly experienced clinicians in child neurodevelopment. We integrate parent/carer interview, a focused child session, and standardised input from school. Validated rating scales (including SRS-2 and Conners 4™) help quantify traits and functional impact across settings. The result is a balanced, evidence-based formulation that clarifies where traits overlap, where they differ, and what will make the most difference day to day.

Following the assessment you’ll receive a single, practical diagnostic report to share with your GP and school. It sets out the findings, confirms diagnoses where met, and provides tailored recommendations for the classroom, home routines and next steps. Appointments are typically available within weeks, helping families access support sooner.

Understanding ADHD Symptoms

Symptoms often manifest differently in individuals and can have a significant impact on various aspects of life.

What is a combined child ADHD and autism assessment?
A combined child ADHD and autism assessment is a detailed evaluation that looks at whether your child meets the diagnostic criteria for ADHD, autism, or both. It is designed to build a joined-up understanding of your child’s strengths, differences and support needs across home, school and everyday life.
This assessment is suitable for children where there are concerns about both ADHD and autism traits, or where it is unclear which diagnosis may best explain their difficulties. It can be particularly helpful where there are overlapping concerns around attention, behaviour, social communication, sensory processing and emotional regulation.
Assessments are carried out by experienced neurodevelopmental clinicians, including professionals with expertise in both ADHD and autism. The assessment process follows recognised diagnostic standards and considers your child’s presentation carefully and thoroughly.
The online assessment is a structured process rather than a single appointment. It may include a developmental and medical history, parent questionnaires, school feedback, direct clinical assessment completed remotely, and a review of any previous reports or relevant background information.
Yes. Parent information is an important part of the process, and school feedback is often very helpful where available. This allows the clinician to understand how your child presents across different settings and to build a fuller picture of their needs.
A combined assessment allows clinicians to look at ADHD and autism together in one pathway. This can help provide a clearer and more complete picture of your child’s profile, rather than splitting their needs across separate assessments.
The assessment looks at areas such as attention, impulsivity, activity levels, social communication, sensory differences, emotional regulation, behaviour, learning and developmental history. It may also consider whether other factors, such as anxiety, trauma or learning differences, could be relevant.
No. A combined child assessment is more than a brief screening or checklist. It is designed to gather information from different sources so that any diagnosis, or decision not to diagnose, is careful, robust and evidence-based.
After the assessment, you will receive a comprehensive report explaining whether your child meets the criteria for autism, ADHD, both, or neither. The report is designed to be clear and practical, helping you understand how your child’s profile may affect learning, behaviour, social interaction and day-to-day life.
Yes. The report can be shared with schools and is written to help teachers, SENCOs and other professionals understand your child’s needs more clearly. It includes practical recommendations that may help support your child in the classroom and across wider school life.
Yes. The report may form an important part of the evidence used for SEN support planning, an Education, Health and Care Plan application, or an EHCP review. It explains your child’s needs, the impact on learning and daily functioning, and the kinds of support and adjustments that may be appropriate.
Yes. The report includes practical recommendations tailored to your child’s needs. These may relate to support at home, in school and in other settings, so families and professionals have clearer guidance on the next steps.
Yes. If ADHD is diagnosed and medication is considered clinically appropriate, medication options can be discussed with a consultant psychiatrist. This includes considering benefits, possible side effects, monitoring and how treatment may fit alongside non-medication strategies and autism-informed support.
In many cases, the aim is to move to shared care once ADHD medication is stable and effective. Clear documentation can be provided for the NHS GP, including treatment summaries and titration details. However, the final decision always rests with the GP and local NHS policy.

Yes. Follow-up appointments can help families understand the outcome of the assessment, review next steps, discuss support at school and, where relevant, review medication or wider treatment plans.

Yes. Online appointments can be a helpful option for families who would prefer to avoid travel or need something that fits more easily around school and family life.
