Adult ADHD
Assessment
A thorough, consultant-led diagnosis for adults — precise, personal, and built around how ADHD actually affects your life and your work.

Precision, not a check-box exercise
Your ADHD assessment is led personally by Consultant Psychiatrist Dr. Saal Seneviratne. It goes well beyond a simple label — a careful clinical look at how your attention, focus and energy really work, and what will genuinely help.
It's designed with capable, busy adults in mind: people who have spent years quietly compensating, and sense there's more to the picture than "trying harder."
How ADHD shows up in adults
In adulthood, ADHD rarely looks like physical hyperactivity. Far more often it's executive dysfunction — a persistent difficulty with the brain's "command centre" that no amount of willpower fully resolves.
This isn't a deficit of willpower. It's a difference in how the brain regulates attention and drive — and a proper assessment gives you the clarity to work with it.
Task paralysis
Struggling to begin high-priority work even when the motivation, and the deadline, are both clearly there.
Variable focus
Intense "hyper-focus" on new or interesting tasks, then real difficulty sustaining attention on routine but essential ones.
Emotional dysregulation
Frustration, overwhelm or burnout from the constant effort of masking symptoms in a professional setting.
The compensatory cycle
Leaning on late nights and adrenaline to hit deadlines — and paying for it with chronic exhaustion.
Why it happens: the dopamine gap
In the ADHD brain, the pathways responsible for planning and sustained focus often don't receive a steady supply of key signalling chemicals — particularly dopamine and noradrenaline. Low-stimulation tasks can feel genuinely, physically effortful, while novel or urgent ones come easily.
Understanding this is what shifts things from self-blame to strategy. Your assessment looks closely at how your neurochemistry interacts with your work and life, so any plan fits the way your mind actually operates.
A three-part assessment
Built to give the most comprehensive, clinically robust and personally relevant diagnosis possible.

Gold-standard diagnosis
We use the DIVA-5, a structured diagnostic interview for adult ADHD, examining symptoms across both your childhood and adult life to reach a robust, formally recognised diagnosis.

Whole-person evaluation
ADHD rarely travels alone. We screen for masking and for conditions that can mimic or accompany it — anxiety, low mood, burnout, sleep problems — so your plan reflects the full picture.

A clear way forward
A diagnosis is a starting point, not the end. You receive a tailored management plan, which may include medication, therapy and practical strategies suited to your life.
The clinical journey
A clear path from first enquiry to a plan you can act on.
Clinical pre-screening
You complete validated screening tools and a history questionnaire through our secure portal, so your consultation is spent on insight, not paperwork.
Specialist consultation
A thorough diagnostic session with Dr. Saal, in person at our Harley Street clinic — the depth of inquiry a remote consultation can't offer.
Comprehensive report
You receive a formal report you can share with your GP or employer to support workplace adjustments or ongoing care.
Management plan
A follow-up to talk through your tailored way forward — whether that's medication, therapy, or practical adjustments to suit how you work.
10 Harley Street, London
Assessments take place in the heart of London's medical district. Private, calm and consultant-led throughout.
Enquire about an assessment
Because a proper diagnosis calls for a full clinical review, we don't offer automated bookings. Every assessment begins with a short enquiry, so we can make sure it's the right step for you.
