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 with Dr. Kooner. 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 Dr. Kooner 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. Dr. Kooner 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, Dr. Kooner 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 and Dr. Kooner.

ADHD Assessment FAQs

A few of our frequently asked questions about assessments

What is the assessment for ADHD?

FAQ arrow

ADHD assessments typically involve a series of evaluations to determine if an individual meets the DSM criteria for Attention Deficit Hyperactivity Disorder. These assessments can include interviews with the individual, their parents or caregivers, and teachers to gather information about symptoms and behaviours. Additionally, questionnaires and rating scales may be used to assess the severity of symptoms and their impact on daily functioning. Other assessments, such as cognitive neuropsychology testing and behavioural observations, may also be carried out to provide a comprehensive understanding of the individual's difficulties. Overall, the assessment process for ADHD aims to accurately diagnose the condition and develop an appropriate treatment plan to help manage symptoms effectively.

What does an ADHD assessment for adults involve?

FAQ arrow

An ADHD assessment for adults typically involves thoroughly reviewing the individual's medical history, symptoms, and behaviour patterns. It may include self-report questionnaires, interviews with family members or significant others, and cognitive testing to assess areas such as attention, impulsivity, and hyperactivity.

Is an ADHD assessment available in the UK?

How much does an Adult ADHD assessment cost?

What happens if I'm diagnosed with ADHD?

FAQ arrow

If you are diagnosed with ADHD, you will receive a proposed treatment plan along with options tailored to your diagnosis, as well as an information pack outlining the next steps for implementing your treatment plan.

What if I decide to take medication?

FAQ arrow

For adults with ADHD, treatment often includes stimulant medications such as Methylphenidate (Ritalin, Concerta) and Amphetamine-based drugs (Adderall, Vyvanse). These medications help improve focus, attention, and impulse control and are usually prescribed in higher doses compared to those for children. Non-stimulant options like Atomoxetine (Strattera) are also available, particularly for adults who have additional conditions like anxiety or heart issues.

ADHD titration involves starting with the lowest dose of ADHD medication and gradually increasing it. It may take up to a week to notice a difference in your symptoms when taking the medication.

It’s common to have a few side effects with ADHD medication, but titration is how we avoid this by gradually increasing the dose. Some side effects are reduced appetite, weight loss, transient blood pressure increases, headaches and trouble sleeping.

How much does ADHD medication cost?
FAQ arrow

Medication is recommended as the first-line treatment in ADHD for adults and certain age groups in childrenwith clinically significant impairment in their life (NICE, 2008). Any medication must be considered carefully along with any health concerns or other issues that would contraindicate a trial of medication. Taking into account your diagnosis and symptoms, consideration of a trial of medication may be appropriate to determine whether this would assist you with your ADHD symptoms. Medications have been found to improve attention span, task completion and self-organisation, whilst reducing impulsivity, distractibility, and restlessness.

There are many myths about treatment. Treatment carries fewer risks than not taking treatment. Please find a useful video discussing common myths around ADHD medication: https://www.youtube.com/watch?v=JCIT0YbNSCU Life with unrecognised ADHD often leads to mental health problems. It is important to consider the impact of these as well as ADHD on wellbeing. Treatment with medication will likely improve your symptoms of ADHD and this can change how other issues impact on your wellbeing.

Safety Notice: ADHD medications can sometimes be unsafe for individuals with pre-existing heart conditions. Therefore, an interim evaluation, such as an ECG, may be required from your GP (you will be advised if you need these investigations). If needed, we can recommend private GPs in your area who offer fast turnaround times.

NHS waiting times for ADHD assessments vary by location and can be exceptionally long, with some areas facing backlogs that may take up to eight years to clear. Exploring alternatives, such as exercising your Right to Choose, could be worth considering.
