An ADHD assessment is a structured clinical interview carried out by a qualified clinician to determine whether someone meets the diagnostic criteria for Attention Deficit Hyperactivity Disorder (ADHD). The goal is to understand your symptoms, how they affect your daily life, and whether ADHD or another condition may be the cause.

If you think you may have ADHD, there are a few different ways to access an adult ADHD assessment in the UK. 1. Speak to your GP For many people, the first step is to make an appointment with your GP. You can explain the symptoms you are experiencing and how they affect your daily life. If your GP believes ADHD may be a possibility, they can refer you to a specialist service for a full assessment. 2. NHS referral and waiting lists After referral, you may be placed on an NHS waiting list to see an ADHD specialist such as a psychiatrist or specialist clinician. Waiting times can vary depending on your local service. 3. NHS Right to Choose (England) If you are registered with a GP in England, you may be able to use the NHS “Right to Choose” pathway. This allows you to ask your GP to refer you to a qualified provider of your choice for an NHS-funded ADHD assessment. 4. Private ADHD assessments Some adults choose to access a private ADHD assessment. This usually allows for shorter waiting times and direct booking with a specialist clinician. Private assessments can take place online or in person and follow the same structured diagnostic process.

A private ADHD clinic for adults provides specialist services for people who believe they may have Attention Deficit Hyperactivity Disorder (ADHD) and want a clear diagnosis, professional guidance, and treatment options. Private clinics are designed to offer faster access to ADHD assessments compared with many public healthcare pathways. They provide a structured diagnostic process carried out by experienced clinicians who specialise in assessing ADHD in adults. Most private ADHD clinics offer a range of services, including: Comprehensive ADHD assessment A detailed clinical assessment to determine whether you meet the diagnostic criteria for ADHD. This usually involves discussing your current symptoms, childhood history, education, work life, and how attention or impulsivity difficulties affect your day-to-day functioning. Evidence-based diagnostic tools: Clinicians often use recognised screening questionnaires and structured interviews to ensure the assessment follows established ADHD diagnostic guidelines. A full diagnostic report: After the assessment, you will typically receive a written report outlining the assessment findings, whether ADHD has been diagnosed, and recommendations for support or treatment. Medication assessment and titration: If ADHD is diagnosed and medication is appropriate, a specialist prescriber may guide you through treatment options and carefully adjust medication over time to find the most effective dose. Ongoing support and follow-up care: Many clinics also provide follow-up appointments, medication reviews, and advice on strategies to help manage ADHD symptoms in everyday life, work, and relationships. Private ADHD clinics can be a helpful option for adults seeking timely access to diagnosis, personalised treatment plans, and specialist support to better understand and manage ADHD.

At ADHD Assessment and Treatment, adult ADHD assessments are conducted by qualified and experienced clinicians who specialise in ADHD. The assessment is carried out by a trained ADHD specialist clinician, ensuring the process follows recognised clinical guidelines used for diagnosing ADHD in adults. During the assessment, the clinician will take time to understand your experiences in detail. This includes discussing your current symptoms, exploring your childhood history, and looking at how attention, impulsivity, or organisational difficulties may affect different areas of your life such as work, education, and relationships. Your clinician will also use structured diagnostic tools and evidence-based questionnaires to support the assessment process. This helps ensure that the evaluation is thorough, consistent, and based on established ADHD diagnostic criteria. If ADHD is diagnosed, you will receive a comprehensive written report explaining the findings and outlining recommended next steps. Where appropriate, you may also be referred to a qualified nurse prescriber within the service who can discuss treatment options and medication titration. Our aim is to provide a professional, supportive, and thorough assessment process, helping adults gain clarity about their symptoms and access appropriate support if ADHD is diagnosed.

Our adult ADHD assessment is a structured clinical process designed to build a clear and accurate picture of your experiences and whether they meet the diagnostic criteria for ADHD. The process usually involves three main stages: Pre-assessment questionnaires Before the appointment, you’ll complete a screening pack which includes an ADHD self-report checklist and background questionnaire about your history, symptoms, and daily functioning. This helps us understand your experiences before the assessment. Comprehensive clinical assessment (90–120 minutes) The full assessment is carried out with one of our clinicians and can be done online or face-to-face in Preston. During this session we use recognised diagnostic tools such as the DIVA-5 structured ADHD interview, along with NICE guideline criteria, to explore your current symptoms, childhood history, and how these affect different areas of your life. Diagnostic report and outcome After the assessment, all information is reviewed and a detailed diagnostic report is prepared. This report explains whether ADHD criteria are met, outlines the assessment findings, identifies the ADHD presentation type (if applicable), and provides practical recommendations and next steps. Reports are typically provided within 2–4 weeks. If ADHD is identified, we can also discuss treatment options and further support.

The ADHD assessment itself typically takes 90–120 minutes and involves a detailed clinical interview reviewing your symptoms, history, and daily functioning. Before the appointment, you will complete screening questionnaires which help determine whether a full ADHD assessment is appropriate. After the assessment, the clinician reviews all information and prepares a comprehensive diagnostic report, which is usually provided within 2–4 weeks. The report confirms whether the diagnostic criteria for ADHD are met and includes recommendations for next steps. Overall, from the assessment appointment to receiving your report, the process usually takes around 2–4 weeks.

ADHD screening for adults is often an important first step in identifying whether Attention Deficit Hyperactivity Disorder (ADHD) may be present. While screening alone does not provide a formal diagnosis, it helps determine whether a full adult ADHD assessment is recommended. Screening typically involves completing evidence-based questionnaires or symptom checklists that look at common ADHD traits such as difficulties with concentration, impulsivity, organisation, and time management. These tools are designed to identify patterns of symptoms that are commonly associated with ADHD in adults. For many people, ADHD symptoms may have been present since childhood but were never recognised or formally assessed. Adult ADHD screening can help highlight these patterns and guide the next steps toward a professional diagnostic evaluation. However, screening results alone cannot confirm ADHD. A comprehensive ADHD assessment conducted by a qualified clinician is required to make a formal diagnosis. During this assessment, the clinician will explore your current symptoms, childhood history, and how these difficulties affect different areas of your life. If you suspect you may have ADHD, completing an initial screening and then seeking a specialist adult ADHD assessment can help provide clarity, accurate diagnosis, and access to appropriate treatment or support.
