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.

My experience with them Private ADHD was brilliant. The staff are very helpful and times saving and you just got what you needed instant no wasting time. God bless them. I was actually really worried about getting the medication for my daughter. She was struggling for a long time and we couldn’t get prescribed, 24 hours I’ve seen the doctor and I got my medication. I highly highly recommend them if you’re struggling with ADHD please contact them ASAP. Your life will be sorted. Thank you.

Very happy, I was being messed about elsewhere these guys sorted me out feeling much better about my exams. I also got extra time and rest breaks sorted out with the school when other letters from other companies were rejected. The dr runs an academy so was super knowledgeable and helpful felt very lucky.

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 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'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."
