We offer comprehensive assessments for ADHD, ASD, or a combination of both. Our assessments are designed to provide clarity and support for children and adolescents who may be experiencing challenges related to attention, behaviour, or social communication.
The assessment process involves thorough interviews, standardised questionnaires, and observations that take into account the child’s developmental history and current functioning. We collaborate closely with families, educators, and other professionals to gather a complete picture of the child's strengths and needs.
Upon completion of the assessment, we provide detailed feedback and recommendations tailored to the individual. Our goal is to empower families with the information they need to make informed decisions about appropriate interventions and support strategies.
ADHD Assessment
If you are concerned that your child may have ADHD, our diagnostic clinic offers a thorough, efficient, and expert assessment — completed in a single appointment with a same-day report.
Attention Deficit Hyperactivity Disorder (ADHD) presents differently in every child. Some children are visibly hyperactive and impulsive; others struggle quietly with attention and focus. Many are not identified until difficulties at school or home reach a point of crisis. An accurate diagnosis is the first step to getting the right support in place.
What the assessment involves
Your child's ADHD assessment is led personally by Dr Athina Zakynthinaki and takes approximately 1.5-2 hours. It includes:
• QB Test— a computer-based objective assessment measuring attention, activity levels, and impulsivity. This is a highly sensitive and accurate tool that provides measurable data to support the clinical assessment.
• Young DIVA diagnostic interview — a structured interview with parents or carers and your child exploring your their ADHD symptoms across different settings and developmental history.
• Clinical observation of your child during the appointment.
• Conners 4 rating scales — completed by parents and teachers to capture how your child presents across home and school environments.
• Screening for co-existing conditions — including anxiety, autism, learning difficulties, and other presentations that can look like or co-occur with ADHD.
• Immediate verbal feedback on the diagnostic decision at the end of the appointment.
• Full written diagnostic report and treatment plan — provided the same day.
The role of school
School input is a required part of our ADHD assessment. ADHD must be present across more than one setting to meet diagnostic criteria. Before your appointment, teachers will be asked to complete a short questionnaire — this typically takes around 15–20 minutes.
For home-educated children, we accept input from tutors or other professionals who work regularly with your child in a structured setting.
After the assessment
You will leave your appointment with a clear diagnostic decision and a full written report. If your child receives an ADHD diagnosis and you wish to explore medication, we offer an ADHD Medication package covering six medication review appointments, prescriptions, and titration support.
If no diagnosis is made, the report will still include clinical findings and recommendations for any appropriate support.
Autism Spectrum Condition Assessment
Our autism assessment is a comprehensive, multidisciplinary evaluation led by Dr Athina Zakynthinaki and conducted alongside a Speech and Language Therapist or an Occupational Therapist.
Autism Spectrum Condition (ASC) presents differently in every child, and can be particularly difficult to identify in girls, in children who have learned to mask their difficulties, or in those with high academic ability. Our assessment is designed to look beyond surface behaviour to understand your child's underlying profile.
What the assessment involves
The assessment consists of two appointments, which can take place on the same day depending on our and your availability:
Appointment 1 — ADI-R (Autism Diagnostic Interview-Revised)
A structured interview with parents or carers lasting approximately two hours. Dr Athina Zakynthinaki will explore your child's developmental history, social communication, language development, play, and repetitive or restricted behaviours. This is conducted without your child present, allowing you to speak openly.
Appointment 2 — ADOS (Autism Diagnostic Observation Schedule)
A standardised observation session with your child. This is a naturalistic, semi-structured assessment designed to observe social communication and interaction in a relaxed, non-threatening way. It is presented as a series of activities and conversations.
The role of school
School input is a required component of the autism assessment. Teachers provide essential information about how your child presents in a structured social environment. We will send questionnaires to your child's school before the appointment.
For home-educated children, we accept information from tutors, coaches, or other professionals who work regularly with your child.
After the assessment
Following the assessment, you will receive a full multidisciplinary diagnostic report. This includes the findings from each member of the team, a diagnostic conclusion, and detailed recommendations for support — at home, at school, and beyond. A 30-minute feedback appointment with Dr Athina Zakynthinaki is included to discuss the findings and agree next steps.
Important
Management of risk is a critical aspect of mental health care, and it's important to emphasise that such services are primarily available through Child and Adolescent Mental Health Services (CAMHS) within the NHS. While we are committed to making appropriate referrals based on individual needs, we must clarify that we are unable to provide urgent support or handle emergencies due to the limitations of our remote working arrangements. For immediate concerns or crisis situations, it is essential to contact your local emergency services or visit the nearest accident and emergency department. Our focus remains on ensuring that every child and adolescent receives the appropriate level of care through the proper channels.
