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 specialist.

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.

I had a brilliant experience. The team was amazing and made me feel very at ease as it can be quite daunting. They have stayed in contact with me all the way up to my assessment. I feel like they went above and beyond to make sure I had the right care. Oliver Trafford was amazing and reassured me that everything was going to be okay. He answered one of my questions. Angel was an absolute delight by helping me and keeping in contact, and listening to me at any time that I messaged...

The customer service team were fantastic. Responded quickly and never skipped any important information I had. They always answered any questions I had. Oliver was amazing in the assessment. He let me rant on a little bit and I never felt like I couldn't speak. He was always willing to sit and listen to my answers, and if there were topics I didn't want to answer he made sure to move on. I never felt forced. I can't say thank you enough

I tried Concerta 38mg as part of my ADHD treatment, but unfortunately, it wasn’t the right fit for me. Despite not being able to continue the full course of treatment due to financial reasons, Dr. Pav was incredibly understanding and supportive. He advised me free of charge and kindly arranged to transfer my care agreement to my GP at no additional cost. If I decide to return to a private clinic in the future to continue managing my ADHD, I would 100% choose to work with Dr. Pav again

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

I waited nearly 2 years for an NHS ADHD diagnosis; following the NHS appointment in April I was told the wait to start medication would be 8-10 months. 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. Having access to medication has been an absolute game changer for me and I am so thankful to Dr Kooner

I have found that it has helped me in coping with my ADHD symptoms and have benefited from the one on one consultations with my assigned Doctor. It has helped me so much that I can talk to someone who can understand how I feel and give sound advice on how to cope with my anxieties and concerns. and prescribe medications to help achieve this. To have waited for any sort of diagnosis through the NHS would have taken years...

I first met with Dr Kooner about my daughter who had already been diagnosed with ADHD but I just couldn't find anyone who could prescribe. Dr Kooner spent a long time explaining that the person prescribing has to be the one that had performed the assessment. He kindly repeated the assessment efficiently & at a reasonable fee, arriving at the same diagnosis of my daughter with ADHD. Since then his management of her care has been absolutely second to none. We meet every 3 weeks...

Dr Kooner is so good, we already had a diagnosis for our 14 year old daughter but urgently needed to start treatment. Dr Kooner saw us within one week and we had medication delivered within a couple of days. The service is excellent and we feel extremely lucky to have found him. Our daughter has started treatment now and after just 3 weeks we have noticed positive improvements.

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."

"Very helpful doctor. 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."

"I have been suffering from a significant number of ADHD symptoms as a child, which worsened over the years. This convinced me to get assessed for ADHD privately, as the NHS waiting list is extremely long (up to 4 years for an assessment).

I liked how he intensively explained what causes ADHD, how ADHD runs in families, and such. Finally, as someone who has ADHD, he completely understands the debilitating and crippling effects ADHD has had on me academically, socially, and mentally throughout the years."
