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.

"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 was already ADHD diagnosed back home and have recently moved to London. The NHS initially refused to provide medication and sessions for the psychologist has two years waiting list. I found this private clinic, and they were immediately very helpful, always responding promptly and assisting me with any issues. The online sessions also helped me navigate my daily life more better. Later on, we successfully established a shared care agreement with my GP, and the clinic did not charge extra for this service, unlike other clinics"

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."

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 for this!"
