ADHD Assessment and Treatment.

ADHD is a neurodevelopmental condition that impacts attention regulation, impulse control, and activity levels. Symptoms can present differently at different life stages, and in some people, they may go unnoticed for years.

Typical ADHD symptoms

Many individuals with ADHD also experience challenges with sleep, emotional regulation, academic or professional performance, and self-esteem.​

New Adult ADHD Assessments London

Our new adult ADHD assessments are for people who have not previously received a formal diagnosis.

During your appointment, your psychiatrist will take the time to understand the difficulties you are experiencing, how long they have been present and how they affect different areas of your life. You will receive a written diagnostic report, along with clear recommendations based on the outcome of your assessment.

Appointments are available online or in person at our Harley Street clinic in London.

Existing ADHD Diagnosis Assessments London

You may already have an ADHD diagnosis but feel that your current support no longer reflects your needs or circumstances.

An existing diagnosis assessment gives you the opportunity to discuss your current experiences with a consultant psychiatrist. We will review your previous diagnostic report and any relevant clinical documents before confirming whether this appointment is suitable for you.

Please note your previous psychiatric reports and letters will need to be sent to us before your appointment. Please email enquiries@diversemindsclinic.co.uk

Reviews are available online and at our Harley Street clinic.

Book an Assessment

Private adult ADHD assessments are available at Diverse Minds Clinic, 10 Harley Street, London, W1G 9PF, or online across the UK.

Choose a new adult ADHD assessment if you are looking for your first formal diagnosis. Choose an existing diagnosis review if you already have a diagnostic report and would like your current needs reviewed.

Please contact the clinic on 020 3576 5911 or WhatsApp us if you are unsure which appointment to book.

Choosing the right medical professional for your circumstances is not easy; I know this as someone with high-masking autism & ADHD co-occurring. I’d been curious to explore my symptoms for quite some time, aware how ADHD behaviour with ASD could be more nuanced to identify, & may overlap, or cancel-out. I also felt confused though, having previously been dismissed by one medical professional, on the basis I had been able to sit still during our conversation (an outdated view BTW!). I subsequently carried out a lot of research before finding Dr Alessandra Cappai, and I’m incredibly pleased I did. When scheduling my appointment, Zahra was incredibly considerate in communicating the process effectively, so I felt comfortable with what to expect. Plus, I didn’t have to wait for months either. Dr Cappai was particularly helpful at directing my assessment so conversation remained focused on the most relevant details and explored my personal experience, whilst playing back comments in a way that made me feel understood. This ensured time was used effectively to also then offer support, rather than simply assess. I left my assessment equipped with useful action points which I have been able to implement immediately to help ease certain pain-points. I was also provided some useful research pointers and concepts to consider, on the topic of various approaches for treatment. I am confident I will be choosing Dr Cappai’s expertise again in the near future, as I follow-up on some of these options.

I’ve met Dr Cappai several years ago and she has a warm personality, you really feel she is listening to you and understanding where you are coming from. The online appointments are very helpful, particulary living abroad, and they work very well.

I have been one of Dr Cappai's patients for a couple of years and she helped me understand and manage my ADHD and depression. She has always been flexible and understanding of my needs and her support has really made a positive impact on my mental health.

My daughter has been seeing Dr Cappai (in person and online) since January after an ADHD assessment. We have found Dr Cappai and all the staff at Diverse Minds extremely helpful, professional, supportive and reassuring. I would highly recommend Diverse Minds
