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've known I had ADHD for years. When I used to work in a college, my Head of College told me, and that was quite significant because I assumed he was quite knowledgeable. Fast forward a few years, I discovered self-development, therapy, and spent 10 years deep in that. A few years later, I thought, let’s get assessed. I never thought I needed to do this, especially as someone who has achieved financial success. But this time, I considered it because I realized I needed to slow down...

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.

I had the chance to speak with Dr. Pav while meeting him and his wife during a vacation abroad. It was remarkable to hear about the high level of clinical expertise, empathy, and support that he brings to his ADHD practice. As he described his assessment process, it became clear that he has a deep understanding of how to make what is often a stressful and overwhelming experience feel manageable and reassuring for his patients.

I am very pleased with my experience with the clinic. I had gone through another assessment a few months prior with a private psychiatrist and felt very diminished.

"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 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 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."
