Try our 6-question ADHD Test

Free Online ADHD Test London and Surrounding Area

If you’re conveniently located near London and considering an assessment, our free symptom checker offers a preliminary look at your potential ADHD indicators.

This straightforward tool helps evaluate the presence of ADHD symptoms. Should your results suggest further investigation is needed, we recommend proceeding with a full assessment with Dr Shyamal Mashru. This could be the first step towards a tailored ADHD treatment and medication plan tailored just for you.

  • Start

    To complete the ADHD symptom checker you will need to answer each of the following 6 questions based on how you have felt and conducted yourself over the past 6 months.

    There are no right or wrong answers. At the end you will be given a result that will either suggest that ADHD is something that is worth being assessed for if your score is high enough OR, if your score is low, it is unlikely that you would fulfil the criteria for a diagnosis of ADHD.

    Please note, this questionnaire is not diagnostic or a replacement for a full assessment. It is for initial consideration.

Overcoming the challenge of ADHD diagnosis in London

Swift ADHD Assessment in London

Located in Marylebone, London, the ADHD Health Clinic recognise the challenges many face in accessing timely and effective ADHD diagnosis and treatment. The path to obtaining necessary care can be lengthy and frustrating, particularly in densely populated areas like London where demand often outstrips available healthcare resources.

To address these challenges we offer swift ADHD assessments to alleviate the often prohibitive wait times associated with ADHD diagnosis and treatment. Our streamlined processes ensure that accessing the support you need is neither a lengthy or an overly burdensome process.

Dr. Shyamal Mashru, our lead consultant, is at the forefront of providing specialist ADHD support. His expertise and commitment to patient care make him a trusted figure in ADHD diagnosis and treatment. Recognising the initial uncertainty many may feel, Dr. Mashru offers a free 10-minute screening call, providing an opportunity to discuss symptoms and concerns before committing to a full assessment. This personalised approach ensures that you can make informed decisions about your ADHD journey with confidence.

Using Health Insurance for Your ADHD Assessment

Understanding the financial aspects of healthcare is equally important, which is why we facilitate the use of health insurance to cover assessment costs. We collaborate with major insurers such as Vitality Health, Bupa, Bupa Global, Cigna, and WPA making the process straightforward and stress-free.

If you have a health policy with any of these providers, it can help remove financial constraints which could otherwise have hindered your access to essential ADHD services. 

Bridging the Gap Between Private Care and NHS

We are acutely aware of the challenges that come with long NHS waiting lists, which is why many individuals seek private care. Our clinic is dedicated to offering exceptional care in the private sector while also supporting patients within the NHS framework. Where appropriate, we can work alongside your GP to discuss Shared Care Agreements. These agreements aim to transition your care back to the NHS when feasible, ensuring you continue to receive the support you need.
