An accurate ADHD diagnosis is the foundation of effective treatment. Without it, you might spend years treating the symptoms of anxiety or depression without ever addressing the underlying neurodivergence.
To ensure you get the best support available, our clinic conducts expert ADHD assessments that adhere to the NICE (National Institute for Health and Care Excellence) guidelines – the UK’s “gold standard” of ADHD care. We ensure that, no matter what, every diagnosis is safe, accurate, and robust enough to be recognised by the NHS and other healthcare providers.

NICE-Backed Diagnosis - A Multi-Step Assessment Process
ADHD is not something that can be diagnosed with a simple blood test or a five-minute chat. It is a complex neurodevelopmental condition that presents differently in every individual. To capture the full picture, our clinicians follow a multi-layered assessment process, backed by NICE guidelines:
Clinical Interviews
The core of our assessment is the clinical interview.
We start with an empathetic conversation about your life, then our clinicians look at your history from early childhood through to the present day. We then explore your academic experiences, your career trajectory, and your interpersonal relationships, looking for patterns of inattention, hyperactivity, or impulsivity that have been present throughout your life.
Because ADHD is neurodevelopmental, these traits don’t just “appear” in adulthood, though they are often masked until the demands of adult life (like university or parenthood) become too much to manage. That’s why a clinical interview can help shed light on childhood experiences and how symptoms may have manifested back then.
Validated Rating Scales
While the conversation provides the “story”, validated rating scales provide the data. PrivateADHD.co.uk clinicians use internationally recognised tools such as the DIVA-5 (Diagnostic Interview for ADHD in Adults) or Conners Scales to quantify the severity of symptoms and compare them against standardised norms.
By using these tools, we ensure that our clinical experience is backed by objective, measurable evidence.
Informant Reports
With your permission, we may ask a partner, a parent, or even a long-term friend to complete a brief questionnaire or join a portion of the interview. Hearing how your symptoms manifest in different environments – such as at home versus the workplace – is crucial for an accurate NICE-aligned assessment.

Differential Diagnosis: Is it ADHD or Something Else?
One of the most critical roles of a clinician is “differential diagnosis”. This is the process of distinguishing ADHD from other conditions that look remarkably similar.
This is important because symptoms like poor concentration, emotional dysregulation, and restlessness aren’t exclusive to ADHD. They can also be hallmarks of:
- Anxiety Disorders – where “racing thoughts” are driven by worry rather than neurodivergent processing.
- Complex PTSD – where hyper-vigilance can mimic the distractibility of ADHD.
- Mood Disorders – such as Bipolar Disorder or Chronic Depression.
Our clinicians are highly trained to untangle these threads and identify comorbidities. We will actively look for alternative explanations to ensure we aren’t misdiagnosing a different underlying issue.
Meeting the NICE Criteria: The Threshold for Diagnosis
To receive a formal diagnosis under NICE guidelines, it isn’t enough to simply “have” the traits of ADHD – the traits must meet specific clinical thresholds.
Impact on Daily Functioning
The defining factor of a clinical diagnosis is impairment. We all lose our keys or forget an appointment occasionally. However, for an ADHD diagnosis, these symptoms must significantly interfere with your quality of life in at least two major areas – such as your work performance, your social relationships, or your ability to manage a household.
We look for evidence that your symptoms are causing genuine distress or preventing you from reaching your potential.
Persistence Over Time
NICE guidelines require evidence that symptoms were present during childhood (typically before the age of 12). While you may not have been diagnosed as a child, perhaps because you were high-achieving or “quietly” inattentive, the traits must have been there.
Our clinicians are experts at helping you look back through the lens of adulthood to identify these early markers, such as old school reports or childhood memories of feeling “constantly bored” or “getting in trouble for talking”.
Unsure if your symptoms meet the criteria? Our specialists can help you find the answers. Schedule your Initial Screening and take the first step towards clarity. |
Post-Diagnosis: Developing the Treatment Plan
A diagnosis is not an endpoint. Once a diagnosis is confirmed, we move into the “stabilisation” phase, guided by NICE recommendations.
Pharmacological vs. Non-Pharmacological Options
NICE guidelines recommend a tiered approach to treatment. For many adults, medication is a highly effective tool, however it works best when paired with non-pharmacological support. We offer guidance on:
- ADHD-focused CBT – to help manage the “emotional baggage” of a late diagnosis.
- Psychoeducation – helping you understand how your specific brain works.
- Coaching – practical strategies for time management and organisation.
The Shared Care Agreement
We understand that private healthcare can be an investment. To ensure long-term affordability, we work toward Shared Care Agreements. Once you are stable on your medication, we provide a detailed report to your NHS GP. This allows the GP to take over the prescribing at NHS prescription costs, while we continue to provide the specialist annual reviews required by NICE. This “bridge” ensures you get the rapid assessment you need privately without losing the long-term support of the NHS.
