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.

I had a telephone consultation and found him to be calm, attentive, and reassuring throughout. Despite it being a remote appointment, he created a comfortable atmosphere and took the time to listen carefully to my concerns. His questions were clear and thoughtful, and he explained things in a way that was easy to understand. I felt heard and respected, and the consultation gave me confidence in the next steps of the process. A very positive experience overall.

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. I truly appreciate his calm...

It was an absolutely pleasure to be trained. He delivered the ADHD training sessions with exceptional skill and expertise. Facilitated the session with clarity, engagement, and a thorough analysis of the subject, responding to all questions with confidence and depth. I highly recommend the ADHD trainings: Diagnostic and Management. Both sessions offer a comprehensive understanding of gold-standard diagnostic tools and current treatment options, including pharmacological approaches. An invaluable resource for anyone working in mental health or related fields.

I highly recommend training courses to professionals working in this field.

"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."

"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."

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!"

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."
