Adult ADHD Assessment Process at PrivateADHD
Comprehensive Adult ADHD Assessment and Personalized Care
Before your appointment, you’ll be asked to complete some preliminary forms, including a brief symptom checklist and relevant background information. This helps the clinician gain an objective understanding of how ADHD symptoms may have impacted your life. Being open and detailed about your experiences and challenges will allow the clinician to develop a tailored and effective treatment plan.
Assessments are carried out by a specialist adult ADHD consultant or psychiatrist, and you are welcome to bring a support person to your appointment if you wish. After the assessment, you will receive a detailed report summarising the findings, diagnosis, and a personalised plan for managing ADHD that is specific to your needs.
Book your private adult ADHD assessment online at a time that works for you.
Appointments are available without long waiting lists, so you can be seen quickly. All assessments are carried out securely via video call, allowing you to attend from the comfort of your own home.
Once booked, you’ll receive confirmation and details of what to expect next.
Before your appointment, you’ll be sent an ADHD self-assessment questionnaire by email.
You can complete this yourself, or ask someone who knows you well to help provide additional insight.
The questionnaire covers your symptoms, daily challenges, and personal history. This information helps your clinician prepare for the assessment and supports an accurate diagnosis and a more personalised treatment plan.
Your assessment takes place during a one-to-one video consultation with a specialist ADHD clinician.
The session is relaxed and conversational, allowing you to talk openly about your experiences.
You’ll discuss your symptoms in depth, how they affect your daily life, and any concerns you may have. There is no pressure to answer everything perfectly, and it’s completely normal to find some questions difficult. Your clinician will also explain potential treatment and support options.
Within 10 working days of your assessment, you’ll receive a detailed written report by email.
This report clearly explains the outcome of your assessment, including whether you meet the criteria for ADHD and which type has been identified, if applicable.
It also includes an explanation of the findings, recommended treatment options, and an information pack to help you understand your diagnosis and plan your next steps.
If you decide to begin treatment, your care will be fully supported by the clinical team.
This may include follow-up appointments, medication management, and ongoing monitoring of your progress.
Medication can be delivered directly to your door, and shared care arrangements with your GP can be set up where appropriate. Treatment consultations cost £245 (medication costs are charged separately by the pharmacy).
Ongoing support focuses on helping you understand your ADHD, set realistic goals, and develop strategies to manage challenges and build on your strengths.
What is ADHD?
Attention Deficit Hyperactivity Disorder (ADHD) is a neurological condition that is present from birth and often runs in families. It is estimated that around 5% of the population may have ADHD, with many people unaware they are affected. Symptoms usually appear in childhood but are often overlooked, which can result in a diagnosis being delayed until adulthood. ADHD is not caused by poor parenting, diet, or screen time.
Research, including large-scale studies using brain imaging, shows that ADHD is associated with differences in brain structure and function. These findings reinforce that ADHD is a genuine neurological condition, not simply a behavioural issue or “label” for difficult behaviour.
ADHD often occurs alongside other neurodevelopmental conditions, such as autism spectrum disorders. It has a strong genetic component, though the exact genes involved are not fully understood, making inheritance patterns complex and unpredictable. Advanced imaging, such as functional MRI (fMRI), highlights differences in brain activity between individuals with ADHD and those without, providing further insight into how the condition affects attention, impulse control, and executive function.
Common ADHD Symptoms
These are some of the common adult ADHD symptoms you may be experiencing:
What to Expect During an Adult ADHD Assessment
An adult ADHD assessment is a thorough evaluation that gathers information from multiple sources to provide an accurate diagnosis and guide treatment. Here’s what typically happens:
- Detailed Diagnostic Interview: The clinician will ask about your symptoms, medical history, and daily life to understand how ADHD may be affecting you.
- Standardised Behaviour Questionnaires: You (and sometimes a close friend or family member) will complete questionnaires to help quantify the presence and severity of symptoms.
- Review of Past and Current Functioning: Your education, work history, social interactions, and other life experiences will be reviewed to assess how ADHD has impacted different areas of your life.
- Screening for Co-existing Conditions: The clinician will check for other mental health or neurological conditions that may mimic or co-occur with ADHD, ensuring a thorough assessment.
- Input from Loved Ones: Where possible, insights from a family member or close friend can provide valuable context on your behaviour and functioning.
The assessment may take one or two sessions depending on individual circumstances. After reviewing all the information, the clinician can determine whether you meet the criteria for ADHD and discuss a personalised treatment plan.
Treatment Plans & Next Steps after ADHD Diagnosis
If you receive a positive ADHD diagnosis, your clinician will discuss personalised next steps to help manage your symptoms and improve your quality of life. Options may include:
Medication: Your specialist can explain available treatments, how they work, potential side effects, and support you through the process. Medication has strong evidence for improving daily functioning and overall well-being in adults with ADHD.
Cognitive Behavioural Therapy (CBT): CBT helps you identify and change negative thought patterns, equipping you with strategies to better manage your thoughts, emotions, and behaviours related to ADHD.
Group Therapy: Group sessions provide a supportive environment to share experiences, develop coping strategies, and learn practical skills from others facing similar challenges.
Couples or Family Therapy: ADHD can affect relationships and family dynamics. Therapy can help improve communication, build trust, and develop strategies to manage family life together.
A comprehensive post-diagnosis plan may combine these approaches to create a tailored programme of support, ensuring you receive the therapy, guidance, and treatment best suited to your needs.
Stimulant Medications
Stimulant medications are the most commonly prescribed treatment for Attention Deficit Hyperactivity Disorder (ADHD). They work by increasing the levels of certain neurotransmitters in the brain, particularly dopamine and norepinephrine, which help improve attention, focus, and impulse control. These medications have a rapid onset of action, often showing effects within 30 minutes to an hour after ingestion.

Non Stimulant Medication
Non-stimulant medications are an alternative for individuals who cannot tolerate stimulants or when stimulants are ineffective. These medications tend to have a slower onset of action and may take several weeks to reach full efficacy. They work by different mechanisms to improve attention, impulse control, and other ADHD symptoms

Adult ADHD Assessment FAQs
A few of our frequently asked questions about assessments
What is the assessment for ADHD?
ADHD assessments typically involve a series of evaluations to determine if an individual meets the DSM criteria for Attention Deficit Hyperactivity Disorder. These assessments can include interviews with the individual, their parents or caregivers, and teachers to gather information about symptoms and behaviours. Additionally, questionnaires and rating scales may be used to assess the severity of symptoms and their impact on daily functioning. Other assessments, such as cognitive neuropsychology testing and behavioural observations, may also be carried out to provide a comprehensive understanding of the individual's difficulties. Overall, the assessment process for ADHD aims to accurately diagnose the condition and develop an appropriate treatment plan to help manage symptoms effectively.
What does an ADHD assessment for adults involve?
An ADHD assessment for adults typically involves thoroughly reviewing the individual's medical history, symptoms, and behaviour patterns. It may include self-report questionnaires, interviews with family members or significant others, and cognitive testing to assess areas such as attention, impulsivity, and hyperactivity.
Is an ADHD assessment available in the UK?
Yes, ADHD assessments are available in the UK through healthcare providers, such as GPs, psychologists, and psychiatrists. Private ADHD offers professional adult ADHD assessments and ADHD assessments for children in a safe, professional and welcoming environment. You may choose to do an online assessment or visit us at our clinic in London.
How long is an assessment?
The booking process and initial questionnaire should only take a few minutes. The assessment itself involves a 60-minute discussion, followed by a comprehensive assessment report, which will be emailed within 10 working days.
How much does an Adult ADHD assessment cost?
Adult ADHD assessments cost £650.
What happens if I'm diagnosed with ADHD?
If you are diagnosed with ADHD, you will receive a proposed treatment plan along with options tailored to your diagnosis, as well as an information pack outlining the next steps for implementing your treatment plan.
What if I decide to take medication?
For adults with ADHD, treatment often includes stimulant medications such as Methylphenidate (Ritalin, Concerta) and Amphetamine-based drugs (Adderall, Vyvanse). These medications help improve focus, attention, and impulse control and are usually prescribed in higher doses compared to those for children. Non-stimulant options like Atomoxetine (Strattera) are also available, particularly for adults who have additional conditions like anxiety or heart issues.
ADHD titration involves starting with the lowest dose of ADHD medication and gradually increasing it. It may take up to a week to notice a difference in your symptoms when taking the medication.
It’s common to have a few side effects with ADHD medication, but titration is how we avoid this by gradually increasing the dose. Some side effects are reduced appetite, weight loss, transient blood pressure increases, headaches and trouble sleeping.
