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 was already diagnosed in my home country and I moved to London recently. The NHS initially refused to consult me or provide medication, moreover the waiting list for the online sessions with psychologist are two years. I found this private clinic, and they were immediately very helpful, always responding and assisting me with any issues. The online sessions also helped me navigate my daily life better. Later on, we successfully established a shared care agreement with my GP...

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

So good, we already had a diagnosis for our 14 year old daughter but urgently needed to start treatment. They 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.

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 men

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 mentally and be more strategic. I did a lot of research into private ADHD clinics. What I found from places like Reddit is that most do the assessment within a week, but the diagnosis takes another week, and then nearly a month for treatment because that’s a separate appointment. Some of them are even inefficient, you still need to go to the GP for a blood pressure check, even though I can do this at home and record it on video. Then I came across Private ADHD. I booked a same day appointment, 1 PM for a 6 PM slot. Before booking, I had a few questions, which were answered quickly. Unlike other sites where you’re stuck with slow chat boxes, I got responses straight away via WhatsApp, which made things so much easier. Once I booked, they sent me a long form to complete. That actually put me at ease because I knew they were properly considering everything before making a decision. My mum even completed part of it, which added more insight. A few hours later, I was on a live call. He went into detail, asked me a lot of questions, and of course, I already knew I had ADHD. I was very nervous about taking medication, but they answered all my questions. He even referenced scientific studies I could read or watch, which helped a lot. He explained the treatment options, and the next day, I had my medication, all thanks to their private prescription and links to same day delivery pharmacies. Since taking the medication, my life has completely changed. \t•\tI’m not impulsive, I can literally sit at my desk without constantly getting up. \t•\tI’m getting tasks done without procrastinating. \t•\tMy focus at work is deep, I can lock in and actually finish things. \t•\tI’m driving sensibly instead of being all over the place. \t•\tI have so much control over my emotions. For years, I thought therapy was the key to getting my emotions in control. I didn’t need therapy, I needed medication. I used to be all about the holistic approach, but my view on medication has completely changed. He made a great analogy, he said I’m like a Ferrari, going from 0 to 100 instantly, but now, I’m learning to go slower and use other gears. This has other benefits I never even considered. I’m so grateful that I can now access the full part of my brain that I never knew I could. On top of that, they offers WhatsApp support, which is incredible. From appointment to treatment was less than 24 hours. I’m genuinely so thankful. If you’re thinking about getting an ADHD assessment, I highly recommend Private ADHD

The course offered by PrivateADHD.com was v. well structured and presented. It provided a clear, practical framework for ADHD assessment, with excellent coverage of diagnostic tools such as the DIVA 5. The content was engaging and clinically relevant, making it easy to apply directly to patient care. Each section built logically on the last, and the delivery was both professional and approachable. I now feel much more confident conducting assessments and highly recommend this course to any clinician working in ADHD.

"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."

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.

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."
