Good results with autism therapyPosted on Diana RTrustindex verifies that the original source of the review is Google. PTSD diagnosis and treatment I had a very positive experience at Diverse Minds Clinic today. I decided to have a comprehensive psychiatric assessment for childhood trauma, which was a difficult step for me. Dr Cappai has extensive experience in trauma in women, and I was impressed reading her profile. She also worked with women from disadvantaged backgrounds and prisoners. I was diagnosed with cPTSD, and I suffered from recurrent depression all my life. Dr Cappai made me feel finally heard, after years of struggles and I am very grateful to her for this. I am now on my pathway to recovery, and I would recommend Dr Cappai to anyone who has struggled to find a doctor who really listens.Posted on JonathanTrustindex verifies that the original source of the review is Google. Combined ASD and ADHD assessment I was impressed by the quality of care offered at Diverse Minds Clinic. I had a combined ASD and ADHD assessment, and Dr Cappai helped me understand where my difficulties stem from and provided support and possible solutions. I will continue working with Dr Cappai and have just started my ADHD medications titration. On a separate note, the administrative team were very friendly and helpful on the phone, which helped me relax, and Dr Cappai's office and the building in Harley Street were very pretty.Posted on John WilsonTrustindex verifies that the original source of the review is Google. At 49, I finally received a diagnosis of ASD and ADHD—a moment that brought both relief and a new sense of understanding. The professionalism of everyone at Diverse Minds Clinic truly stood out. From my very first call, the staff answered every question with patience and kindness, never once making me feel like a burden. Throughout the evaluation, Dr. Cappai made sure I was comfortable by being kind and encouraging, even setting up breaks if I needed them. The consultation room itself was spacious, well-equipped, and neither scary nor unduly clinical. The assessment's thoroughness was what most impressed me. The consultant psychiatrist who performed the evaluation, Dr Cappai, was obviously an expert in her area and fostered an atmosphere that allowed me to be myself. The report that followed was incredibly detailed; they listened, they didn't rush, and it provided me with the clarity I've been looking for my entire adult life. I was confident in the diagnosis since I had a consultant psychiatrist who specialised in neurodevelopmental disorders. I heartily suggest it.Posted on T WTrustindex verifies that the original source of the review is Google. Great ADHD assessment from Dr CappaiPosted on Libby OsborneTrustindex verifies that the original source of the review is Google. Such a lovely experience, after years of fighting with medical professionals i finally felt seen, heard and understood. Nothing but good words to say about Dr Alessandra CappaiPosted on S STrustindex verifies that the original source of the review is Google. Diagnosis of any neurodiversity greatly depends on the expertise of the assessor. There are lots of clinic who does ADHD and Autism assessment including some that you can chose through NHS Right to Choose. But I came across mixed reviews about all of them. BBC panorama report about few clinics really shocked me and made me even more confused about where to go for diagnosis. I did extensive research about different clinics and came across Dr Alessandra Cappai's clinic Diverse Minds Clinic. I wasn't quite confident about this either. They don't have a phone number to receive calls but they have one for only what's app messages. That made me little dubious. I sent an email saying I had few queries if they could call me back. I was pleasantly surprised that Dr Cappai is happy call me for about 10 minutes appointment for answering my queries and that's completely free of charge. She called me exactly on time and answered all my questions patiently. After that appointment, I was confident about her clinic and her expertise. I got my first assessment within two weeks time. They sent all the forms that needed to be filled in straight away and also sent reminder to do them well ahead of time. On day of assessment, I had a three hour long ( I had a combined assessment) session and Dr Cappai asked extensive questions. I am still waiting to get my report as I have not completed all the forms yet. Although they don't have any direct phone number to call instantly but please don't let that put you off. They promise to get back to your queries within 48hours and so far they have not failed and I am sure that will be the case going forward. The other point for which I chose her clinic is because Dr Cappai personally do the titration process which gave me peace of mind. If you are looking for a reliable ADHD or ASD assessment, please go for Diverse Minds Clinic. Thank you Dr Cappai.Posted on Meret BachmannTrustindex verifies that the original source of the review is Google. My experience with Diverse Minds Clinic has been amazing.
