Frequently Asked Questions

A private ADHD assessment is a comprehensive evaluation carried out by a qualified mental health professional to determine whether you meet the criteria for Attention Deficit Hyperactivity Disorder (ADHD). At Harley Street Mental Health, our private adult ADHD assessments in the UK include an in-depth clinical interview, evidence-based diagnostic tools such as the DIVA 5.0, and a review of developmental history and current symptoms. Assessments typically explore how ADHD symptoms impact areas such as work, education, relationships, and daily functioning.
Choosing a private ADHD assessment offers faster access to diagnosis and treatment compared to NHS waiting times. Following the assessment, a formal diagnostic report is provided, and if a diagnosis is confirmed, we offer guidance on ADHD treatment options, including medication, therapy, and lifestyle strategies.
Yes, all of our private ADHD assessments at Harley Street Mental Health are fully compliant with the National Institute for Health and Care Excellence (NICE) guidelines for the diagnosis and management of ADHD. We go beyond the standard requirements by also following the Associated Quality Assured Standards (AQAS) developed by UK adult ADHD specialists. This ensures that our assessments are not only evidence-based but also reflect best practices in the field.
Our clinicians use validated diagnostic tools such as the DIVA 5.0 and follow a structured clinical interview format that meets and exceeds NICE standards. This comprehensive approach includes a detailed review of your developmental history, current symptoms, and the impact of ADHD across different areas of life, including education, work, relationships, and everyday functioning.
By exceeding national guidelines, we aim to provide the highest standard of ADHD care available privately in the UK.

ADD (Attention Deficit Disorder) and ADHD (Attention Deficit Hyperactivity Disorder) refer to the same condition, but the terminology has evolved. ADHD is the current medical term used to describe individuals who have difficulties with attention, impulsivity, and/or hyperactivity, even if hyperactivity isn’t a prominent symptom.
Historically, ADD was used to describe individuals who had trouble with attention and focus but did not show signs of hyperactivity. Today, this would be diagnosed as ADHD, Predominantly Inattentive Presentation, one of three recognised subtypes under the modern ADHD diagnostic criteria.
At Harley Street Mental Health, we assess for all presentations of ADHD, including:
- Predominantly Inattentive Type (formerly known as ADD)
- Predominantly Hyperactive-Impulsive Type
- Combined Type
Yes, we have a dedicated team of CAMHS consultant psychiatrists that can diagnose and treat ADHD in individuals aged under 18
If you have been diagnosed elsewhere, and want to transfer your care to Harley Street Mental Health please do get in touch and we can guide you through the process.

EXCELLENT Based on 301 reviews Posted on parsa mTrustindex verifies that the original source of the review is Google. Dr Sijjad Ijaz was very efficient, and understanding during my consultation. The consultation was well structured and he was very easy to talk to. Great experience overall.Posted on MuscabTrustindex verifies that the original source of the review is Google. Dr Sijjad Ijaz was brilliant. He made the assessment feel like a conversation, he was professional with some friendly banter and made me feel understood. He put my symptoms into words that I couldn’t describe and me agreeing “yes that’s me” and explained my diagnoses and what our options were going forward. With Hsmh the experience was great from start to finish, the booking process was simple with next day appointments. We had to fill in Questionnaires before the assessment which was demanding but got there in the end and the Admin team were understanding and compassionate on key points. Would definitely recommend DR Ijaz, to anyone looking for a serious compassionate idea of their condition.Posted on Jessie TafazzoliTrustindex verifies that the original source of the review is Google. I had a brilliant ADHD assessment with Dr Sijjad Ijaz. I felt listened to and understood throughout. Dr Ijaz explained what was going to happen in what order at the start and then reminded me throughout which helped me remain focused. Dr Ijaz made me feel super comfortable and asked me questions about my posters and fidget toy which calmed my nerves. He gave me time to explain myself, whilst helping me keep on topic by splitting up questions which I found overwhleming into smaller, easier ones. He made me feel able to ask for breaks if needed but because the session was done in such a way to avoid ovewhelm, I didn't need one! Often after long meetings like this I feel super exhausted and drained, but I left the meeting feeling heard, understood and excited for the future. Thank you Dr Sijjad Ijaz!Posted on Gregory STrustindex verifies that the original source of the review is Google. Was very nervous prior to the interview but Dr Sijjad Ijaz was friendly and made the process feel natural very early on. Learnt about myself + tons about adhd and potential treatments in a short time and all my questions were answered to a professional standard. I’m very gratefulPosted on marian franksTrustindex verifies that the original source of the review is Google. Dr Sarah Sullivan is very professional, supportive. Thank you so muchPosted on MatthewTrustindex verifies that the original source of the review is Google. Zero complaints about HSMH, it's affordable, it's extremely quick but also thorough, every single thing was explained clearly and in great detail. The Dr who assessed me, Dr Sarah Sullivan, was absolutely lovely. I came into the assessment incredibly nervous, but was almost immediately calmed once she started speaking. The entire call was detailed, but it didn't feel like an interview or interrogation, it just felt like a regular, pleasant conversation. Anyone wanting to go private for an ADHD diagnosis should absolutely use this place, I'm absolutely delighted.Posted on Donna NaltonTrustindex verifies that the original source of the review is Google. I was able to get an appointment 2 days after contracting Harley street mental health. We spoke to Dr Sijjad Ijaz, he was brilliant. Explained everything clearly and clearly knew what he was talking about. We even received his report on Christmas Day, we came away from the appointment with a sense of relief that a diagnosis had been given. Hopefully enabling a more structured and settle future.Posted on Twiggy GarciaTrustindex verifies that the original source of the review is Google. had a great experience with Dr Sijjad, covered in depth everything I needed to know and was great an answering any questions. I wish I had done this sooner. Would highly recommendPosted on Emma SarjeantTrustindex verifies that the original source of the review is Google. I was incredibly nervous before my assessment but Dr Sijjad Ijaz made me feel at ease from the beginning. I was able to book an assessment for the following day, even with the holidays coming up, and it did not feel that Dr Sijjad was trying to rush me at all. There were a few forms to complete prior to my assessment, including one to be completed by someone who knew me in childhood. I was nervous that the observer forms may have been too vague or not exact due to my specific circumstances, but Dr Sijjad reassured me and even let me send additional documentation that I had located following the submission of forms. Dr Sijjad explained things incredibly well and outlined my options which included both medical and non-medical support, which I appreciated. My case was quite complex, and I knew going into the assessment that it may not be as straight forward. It was explained to me that it needed to be heard in an MDT meeting, and my expectations were managed around this. I was expecting this to take weeks, but the very next day I have received my report and the outcome of the meeting. Dr Sijjad was great and quick at communicating with me, which is amazing particularly as I struggle with uncertainty. Dr Sijjad clearly explained the recommended treatment plan and for the first time I feel a sense of clarity and hope that I can work on my symptoms. I couldn’t recommend Harley Street Mental Health and Dr Sijjad more. Thank you Dr Sijjad for your care and compassion throughout this process.Posted on Samuel TottmanTrustindex verifies that the original source of the review is Google. Nothing bad to say about them at all. I had an ADHD assessment with Dr. Benjamin Walters, who was very understanding and knowledgeable and made me feel completely comfortable. They've been incredibly fast during every step of the process and are willing to answer questions whenever needed. Slightly more expensive than other similar options but very much worth the price for the quality and speed of serviceVerified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
