We’re with you every step of the way

How an ADHD assessment works

To be able to help you in the most positive way, we first need to fully understand your neurodevelopmental makeup and needs. Our specialist team will conduct a thorough, expert assessment to ascertain if you do, or don’t, have ADHD.

step 1


If you think you may have ADHD, our free screening process will give clarity and insight. It will be carried out by our psychology team, led by a consultant clinical psychologist. If the results are indicative of ADHD, we’ll recommend a diagnostic assessment to give a definitive answer.

step 2

Understanding you Better

Before we arrange your assessment, we ask someone who knows you well (ideally since you were young) to fill in a report form and an online screening tool, so we can understand more about you and how you were as a child. This is because neurodevelopmental conditions like ADHD are always with us, right from birth. A better understanding of your strengths and needs helps our clinical team with their assessment, but if you don’t have someone who can help give details don’t worry. We’ll still be able to carry out your assessment and would just ask you to bring as much information as you can about how you were as a child. For example, old school reports.

step 3

Diagnostic Assessment

The diagnostic assessment is carried out by either a clinical psychologist or psychiatrist, who are experts in identifying ADHD in adults.  During the appointment, they will carry out a thorough clinical interview using the DIVA-2, which covers questions about how your symptoms or traits are impacting on your life at home and at work, your relationships, plus what you were like as a child. They will compile all the information that has been gathered during and prior to the assessment and consider this against the DSM-5 criteria to determine whether you do, or don’t, meet the threshold for a diagnosis of ADHD.  The outcome will be explained to you on the day, along with recommendations for adjustments at home and work as well as support options available to you.

step 4

Diagnostic Report

Following the assessment, we will provide you with a comprehensive report giving a full breakdown of the assessment and our findings. The assessment outcome will be clear and easy to understand. It will include both our recommendations and helpful signposting for post-diagnostic support and treatment available at Psicon.

step 5

Treatment and Support

If the results of the assessment indicate that you have ADHD, we will go through all the relevant support options with you. This usually looks like a ‘menu’ of possibilities (including medication and therapeutic options) and we’ll help you select those you feel would work best for you.  If you choose to opt for medication to treat your symptoms, a specialist prescriber will assess your suitability for treatment, carry out some routine tests and, if appropriate, initiate a treatment plan for you.  After your first prescription, you will be asked to have regular reviews with your prescriber who will monitor the efficacy of the medication and any side effects you might have.  When you and your clinician feel that the treatment is working and a stable dose has been reached, we will make a referral to your local NHS ADHD service or GP, who will take over the management of the prescriptions and routine monitoring.

Understanding ADHD

Cherishing unique minds

Neurodiversity is part of being human; a fact of life for many millions of children and adults alike. And having a neurodevelopmental (ND) condition doesn’t mean you have a disease that needs to be cured, but that your neurological functions are organised differently to people who are neurotypical. It’s your unique mind.

However, neurodevelopmental differences can cause great distress when not recognised or understood. This is where the importance of adult ADHD assessments comes into play. Once fully assessed and diagnosed, we can offer tools, support and treatment to help individuals move forward with positivity, peace and productivity.

Some words from our patients

We've helped thousands of patients over the years, and here are some of their thoughts.

I was made to feel at ease straight away

The doctor was very patient and understanding and I was treated with the utmost respect. I came away feeling well informed and I have a plan moving forward for my condition.

Fantastic clinic. I would highly recommend.

I chose to go here to get diagnosed with autism privately. Sadly I have been let down by the NHS since my childhood in the 1980’s and I decided I had to go private, but I would say it was worth every penny and the long drive from my home. Lovely professional staff. Thank you.

Thank you once again for all of your help Psicon!

An outstanding company. Are always willing to help on the phone with any questions, concerns or problems. I would recommend them to anyone.

Quick efficient service.

I could not have been happier with timescales, responses and communication.

The centre is a lovely welcoming place and the professionals put my highly anxious son at ease.

We went to the children's centre to get my son aged 17, a private Autism assessment. From the start the staff were informative and helpful. The centre is a lovely welcoming place and the professionals put my highly anxious son at ease. In fact he even asked when we were going back! After negative experiences with the NHS and school, my son felt that he could finally access support that was right for him. Thank you 😊

Would highly recommend Psicon for any assessments

Absolutely amazing with my son, very easy to talk to and my son loved interacting with the staff.

I would recommend this service to anyone that I know.

I attended the practice in June of 2022. The practice had such welcoming and kind staff members. This really eased any anxieties I had about going to the practice, and set a very calming atmosphere.

Excellent communication and explanation throughout the assessments.

All staff seemed very knowledge, were prompt and courteous and we were given a conclusion by the end of the assessment

From the minute we arrived staff were welcoming and professional.

From the minute we arrived staff were welcoming and professional. Thank you for listening and helping my son to be as comfortable as possible. You were so attentive to his ways and the consultant, speech and language therapist had extensive knowledge and were able to pick up on things I wasn’t even aware of. The support throughout was amazing, everything was explained in detail and I would definitely recommend Psicon to others. Thank you again.

All practitioners were friendly, understanding and really knowledgeable

All practitioners were friendly, understanding and really knowledgeable and informative about autism, but also girls and autism. They managed to put my anxious daughter at ease. They listened carefully, and were responsive to what we were saying. They also gave helpful suggestions to think about with the school and within the family.

They treated me like I was a person

They treated me like I was a person and demonstrated they treat each individual on a case to case base using treatments tailored to the individuals needs. They listened without judgement offering to treat individuals with complex needs.

Exceptional service.

The sessions were well organised. The psychologist was outstanding and it was like they knew me after just a couple of sessions. I would 100% recommend this service. I feel so much better and am going forward with several tools to keep me mentally healthy. I cannot recommend this service enough.

As a parent, it gave me the reassurance that my daughter will grow up knowing how her mind works

My daughter came out of her ADHD assessment feeling very positive about herself and empowered. As a parent, it gave me the reassurance that my daughter will grow up knowing how her mind works and what she needs to put in place to help herself along the way. We are very grateful to have been given such high quality care.

All staff are trained immaculately!

All staff are trained immaculately! Very kind, very helpful. Just wonderful. I could not have asked for a better service!

Frequently Asked Questions

Want to know more about how we can help?

Everyone’s mind is unique. Many of us are neurodiverse. And while the neurological differences that make us individuals can bring challenges, we believe that with understanding, empathy and expert support, everyone can thrive.

See all our FAQs

Will a private diagnosis be accepted by the NHS?

Our assessments fully comply with NICE guidelines, and we use the highest quality and well-regarded clinical model within our service. We are also a trusted NHS provider and often support different NHS Trusts and ICBs with waiting lists. This means a diagnosis made by our service will be accepted by the NHS.

How long will I have to wait before I am assessed?

This often depends upon how quickly we receive the pre-assessment information, but once we've received all questionnaires, we aim to provide an assessment appointment within four to six weeks.

Do you provide ADHD treatment with medication?

Yes, we can provide treatment for ADHD in the form of medication for clients who have been diagnosed and are deemed suitable for treatment. Before deciding whether medication is the right option for you, you will need to meet with a specialist prescriber who will discuss the benefits and risks of treatment and carry out some medical observations (blood pressure, pulse, height and weight). We will also usually ask your GP to carry out an ECG and sometimes routine blood tests prior to deciding if medication is a safe option for you. If you and the clinician agree that medication is appropriate, we will provide you with a treatment plan and give you your first prescription. You will need to be regularly reviewed to monitor for any side effects and to ascertain if your symptoms are being adequately managed. Sometimes the clinician will need to adjust the dose or type of medication you are prescribed, and this will happen alongside monitoring until you reach a stable dose and you and your clinician feel your ADHD is being adequately managed. We will then ask your GP to take over monitoring and prescribing, but we will always be available to you and your GP for ongoing specialist advice and support.

What happens if I'm not diagnosed?

Our assessment process includes a free screening stage, carried out by our psychology team and led by a consultant clinical psychologist. They will look at information contained within your referral, as well as scores from a well-researched and clinically validated screening tool. ‍‍This information will show whether ADHD is indicated, or not. And even though it’s not diagnostic, it will enable you to make an informed decision as to whether to proceed with a full assessment before making any financial commitment. However, it is important to understand that despite the screening process being positive for ADHD, sometimes the outcome of the assessment will be a non-diagnosis. ‍‍This means you don't meet the threshold to be diagnosed with ADHD. If this is the case for you, our clinical team will still be able to provide recommendations for further support and we may even be able to ask your GP to make an onward referral for another type of assessment should this be clinically appropriate.

I don't have anyone to help with the pre-assessment questionnaires, will this affect my assessment?

We ask someone who knows you well to support the assessment process by giving extra information. This is because the Diagnostic Statistical Manual (DSM-5) states that to meet the threshold for a diagnosis of ADHD, symptoms/traits/behaviours must have been present from childhood. Put simply, ADHD is a neurodevelopmental condition caused by physiological differences in the brain, so will have been with you all your life. However, we understand that some people won't have anyone to support the process, and while this can make it trickier to conclude the assessment, it won't prevent the assessment from going ahead. If you aren't able to find someone to support you, we would advise you to bring as much information as you can that shows your strengths and needs as a child, for example old school reports.
