I'm glad I took the time to do this.
I wasn't sure what to expect going into my assessment with Dr. Hossein Rostamipour but if I had any worries he soon settled them
He was courteous and professional, he made me feel at ease and explained everything in detail. I never felt rushed and by the end of the assessment we were laughing.
I felt cared for and listened to.
He had lots of patience and im glad I chose him to speak with.
Thank you Dr Rostamipour.

Great experience so far
Can only speak on the assessment part as that is the only part I have completed. Assessor was very professional and fair. Very quick service. I had an assessment same day which is the best availability I have seen. Assessor made me feel relaxed and like I could speak freely. Also felt that the assessment is very thorough and detailed so I feel that my results are accurate.

Thorough and Professional Assessment
I was pleased I'd booked the ADHD assessment with Dr Sani as she was very thorough and professional throughout, so that I felt confident in the diagnosis given.
She was also patient and understanding during the assessment, so that my initial trepidation was eased quickly and a rather demanding process was made so much easier than it could have been.
I'd certainly recommend Dr Sani and the ADHD Centre.

Dr Mohhamadnisab - Thorough, Knowledgeable, Reassuring
Having struggled all my life in many areas, reading an article about ADHD around a year ago was a real lightbulb moment. Even so, the practical part of me was skeptical about getting a diagnosis, particularly as I knew I would have to pay to go privately due to NHS waiting times in my area.

A recent escalation in my symptoms and affect on my family, led me to push the button and finally seek a diagnosis and the ADHD centre had good reviews at what seemed like a fair price. The booking process was simple and I chose to speak to Dr Mohhamadnisab. I researched him, read his individual reviews online and alongside his positive reviews, it was a negative review that made me trust that he was the doctor to speak to. Whilst the perception the negative reviewer gave was of someone who didn’t want to give them a diagnosis, what I perceived was him being very thorough and diligent. On meeting him, this was very much the case.

During our appointment he was respectful, reassuring and had an eye for detail I was very impressed with. He diagnosed me with ADHD, for which I am very thankful for, but due to a recent fainting episode, he asked me to go for an ECG before he could prescribe. I very much see this as above - a doctor being very thorough and honourable with my best interests at heart. I now look forward to our follow up meetings to work together to find the right medication for me.

She regularly recapped to make sure she had heard everything correctly and noted all important points. She was also very informative explaining things carefully in a way which was easy to understand.

Dr Kelleher was fantastic
Dr Kelleher was fantastic, I was immediately at ease and he made it clear that I may not be diagnosed via our session but I can still be helped. I appreciated that honesty. The assessment was thorough and it was clear Dr Kelleher was taking into account my mental ill health and not just rushing to a conclusion of ADHD, as was the thorough pre-appointment process of having my wife and my parents answer a questionnaire each about me alongside my own questionnaire. As it happens I was diagnosed and feel very safe in his hands for my follow ups and titration. Thank you 🙏

I had long suspected that I had adult ADHD and my family and friends all encouraged me to seek a diagnosis, but the NHS would not see me because I no longer have any documents from my childhood that might support this evidence.

After some online research I found the ADHD Centre and booked and appointment with Dr Rostamipour.

The process was very well structured and both the clinic and the Dr made sure I had provided enough information before concluding that my family's suspicious and mine were correct and it would be beneficial for me to be given medication and further assistance on the matter.

The Dr also made sure to structure things to minimise my economical burden since obviously doing this the private route is rather expensive.

I am extremely happy I decided to take this step and delighted with who they have handled my case.

She listened carefully to my history and addressed any concerns I had, giving me the opportunity to have input in the approach to my treatment. She made a daunting situation much more approachable and provided excellent insights into my challenges and the ways in which my ADHD presents. I am delighted to finally have some answers and to be working with such an empathetic clinician.

Very quick, efficient and straightforward
I was delighted to get an assessment done here within 24 hours having spent several months seeing NHS doctors and then referrals to local private clinics only to meet a dead end each time. This process did involve two good friends input but the overall process was relaxed and easy to do. Having someone just to listen whilst I talked was brilliant and the pace went really well. Highly recommended.

Life-Changing Support from Dr. Chowdhury and The ADHD Centre
Suffering from what I assumed was Chronic Fatigue Syndrome (CFS) my entire life, I was fortunate to have someone notice traits of ADHD that could be the root cause of my struggles. With NHS wait times nearing two years, I decided to seek private help. I was incredibly nervous, so I researched extensively before choosing The ADHD Centre, specifically Dr. Chowdhury. Her reviews made me feel the most comfortable, and I'm so glad I trusted them.

The process was extremely straightforward, but I was still filled with dread before my first appointment. That all disappeared the moment I met Dr. Chowdhury. She is so easy to talk to, and for someone like me, who finds it hard to open up, her calming presence made all the difference. I felt heard, understood, and supported throughout the entire process.

I was diagnosed with ADHD (combination type) and have been guided through titration and a medication change. This has been the best investment I’ve ever made in myself. My quality of life has vastly improved, and I truly believe that Dr. Chowdhury’s compassionate attitude played a huge role in that. She creates a safe space for open and candid conversations during reviews, which has been crucial in finding the right treatment plan for me.

If you’re considering The ADHD Centre or Dr. Chowdhury, I can’t recommend them enough. Their support has been life-changing, and I’m incredibly grateful for the care I’ve received.

The consultation was easily booked and scheduled. I found the consultation itself and Doctor Zadeh to be thorough, constructive and effective. Follow-up and completion of the tests, to ensure the ADHD Centre had access to the information they required to progress to treatment, was a little clunky between the centre, the practice and myself, but that's probably me!

Our Private Autism Assessment Process

A private autism assessment at The ADHD Centre is a structured, thorough process designed to provide clarity and confidence in your diagnosis. Our clinicians use recognised diagnostic tools alongside specialist clinical expertise to ensure the assessment is accurate, comprehensive, and supportive.

Step 1: Pre-Assessment Questionnaires

Before your appointment, you and someone who has known you since childhood will be asked to complete several questionnaires. These help our clinicians understand your developmental history and early life experiences. Informants may find old school reports, childhood photos, or health records useful when recalling details.

Step 2: Clinical Interview & Developmental History

Your assessment is carried out by a specialist clinician and currently takes place online. Family members are welcome to join for part of the session. The interview explores your background, symptoms, and current experiences, and also screens for other psychological conditions that can present with similar features to autism.

Step 3: Diagnostic Tools & Testing

As part of the assessment, you may be asked to complete self-rating screening questionnaires. These are combined with clinical observations and professional judgement to build a complete picture. Autism is ultimately a clinical diagnosis, so the process involves synthesising different perspectives and carefully excluding other conditions.

Step 4: Outcome and Recommendations

At the end of the assessment, your clinician will provide clear feedback, including whether you meet the criteria for an autism diagnosis. You will also receive a detailed written report with practical recommendations. This may include strategies to manage challenges, treatment suggestions for related issues such as anxiety or depression, and referrals for therapeutic support such as autism coaching or cognitive behavioural therapy (CBT).
