Online Adult ADHD Test

Attention Deficit Hyperactivity Disorder (ADHD) is often associated with children, but it also affects millions of adults. Many individuals remain undiagnosed, struggling with symptoms that impact their work, relationships, and daily life. If you suspect you have ADHD, taking an ADHD test online can be a crucial first step toward gaining clarity.

A structured ADHD assessment can help you determine whether you exhibit symptoms of the disorder. While an online test does not replace a professional diagnosis, it provides insights into whether you should seek further evaluation from a clinician.

Results

The ASRS screening tool uses only the scores from Part A for screening purposes. Higher scores in Part B are more indicative of ADHD in adults.

Part A

0 OF 6

Part B

0 OF 12

Although your screening results indicate that a diagnosis of ADHD is unlikely, you are welcome to schedule a formal evaluation with one of our clinical experts.

We advise consulting with a healthcare professional. Your test results show symptoms that align closely with ADHD. However, this test is not a definitive diagnosis, which can only be provided by a trained clinician specialised in ADHD. You may schedule a formal diagnostic assessment with one of our specialist ADHD clinicians, or alternatively, you could speak to your GP.

Our Reviews

I was already diagnosed in my home country and I moved to London recently. The NHS initially refused to consult me or provide medication, moreover the waiting list for the online sessions with psychologist are two years. I found this private clinic, and they were immediately very helpful, always responding and assisting me with any issues. The online sessions also helped me navigate my daily life better. Later on, we successfully established a shared care agreement with my GP...

I can’t thank this clinic enough! The ADHD assessment was thorough, and the staff were so helpful. After my ADHD diagnosis, they explained all my options, including ADHD medication, which has helped me stay organised and focused. I was super happy with everything and might get my girlfriend booked on because she is more worse concentrating than me

By far the best experience so far, within 2 days I was given support and answers that i’ve been waiting to hear as some who was put on the waiting list for 2 years. Oliver has been great at not only listening to my concerns but also educating me on ADHD, making me feel seen and understood, they put me on a plan immediately to help me out and i’m very happy to say i’ve picked Private ADHD!!!

I’d been trying to figure out how to become an ADHD assessor for a while and honestly this course from the ADHD Training Academy ticked every box. It’s well structured but still really practical. The use of actors and mock interviews was a game-changer for me — helped build real confidence. And the DIVA for ADHD was explained in such a clear way. I’ve done another training previously on Harley Street — this was much better than the one there in every way. Trainer was just excellent. And it was cool to hear from a SENCO guest speaker too, brought it all together.

The doctor was very nice and I had a great experience with him. During our online appointment. He was incredibly helpful and efficient getting me a quick appointment and understanding that the medication i'm on now isn't right, and ordering the right medication without any hassle. What really stood out was how clearly he explained ADHD in a way that other doctors haven't. He made me have a much clearer understanding of the next steps in my treatment.

"Dr. Kooner is the best doctor both myself and my daughter have had the pleasure to meet and work with. He has transformed our lives in the way he listened to us and diagnosed both of us. He has an incredible bedside manner, very thoughtful, measured and never judging. He also has a very good aftercare service and you can see and feel he is genuinely caring for you and seeking the best possible outcome. I highly recommend Dr.Kooner"

"I've never been listened to since I've been able to go to the doctors myself for help... It wasn't until I seeked private help with Dr Kooner at PrivateADHD, where I was finally listened to and taken seriously. He went through everything in so much detail and diagnosed me with ADHD. We have regular catch ups to ensure the medication is working for me, which is great... Since being placed on the recommended medication by Dr Kooner, my life has changed for the better, everyone around me has seen such a positive outcome and change."

His deep understanding of the unique challenges that come with ADHD is evident in every interaction and his support extends beyond just medical treatment - for eg. he routinely discusses and offers practical strategies to manage daily life. He takes the time to understand each patient’s individual needs and provides tailored advice that makes a real difference. For anyone seeking a comprehensive, well-rounded approach to ADHD treatment, I would highly recommend Dr. Kooner."

In complete despair, I decided to seek private treatment- I contacted Dr Kooner and was able to book a diagnostic reassessment and initial medication titration appointment within 24 hours, and received my first prescription within 3 days.
