Understanding ADHD
ADHD stands for Attention-Deficit/Hyperactivity Disorder. It’s a neurotype which means it affects how the brain works, especially in areas like attention, focus, self-control, and organisation. People with ADHD are often bright, creative, energetic, and full of ideas but they may also struggle with everyday tasks that others find easy, like staying still, finishing work, or remembering instructions. These challenges are not due to laziness, bad parenting, or lack of effort. They’re linked to how the brain processes information and manages behaviour.
The Key Features of ADHD
ADHD can show up in different ways, often grouped into two main subtypes:
01.
Inattention
- Easily distracted
- Finding it difficult concentrate or finish tasks
- Forgetting things, and / or losing items
- Struggling to follow instructions or stay organised
02.
Hyperactivity and Impulsivity
- Feeling restless or “on the go”
- Talking a lot and / or moving constantly
- Fidgeting, tapping, and / or struggling to sit still
- Interrupting or speaking out without thinking
- Finding it hard to wait for a turn or queuing
Some people mainly have difficulties with inattention (this was previously called Attention Deficit Disorder, ADD), while others are more hyperactive and impulsive. Some people are a combination of both.
ADHD is not
❌ A result of bad parenting
❌ Caused by too much screen time or sugar
❌ A sign of low intelligence
❌ Something you can just “try harder” to overcome
ADHD is a real, recognised condition supported by decades of research. With the right understanding, support, and strategies, people with ADHD can thrive.
ADHD in Children vs Adults
ADHD is not something that only affects children. While signs often appear early in life, many people continue to experience symptoms into their teens and adulthood, although the way ADHD shows up can change over time.
Key Differences
Children (typically ages 4–12)
In children, you might notice difficulties sitting still, following classroom routines, or managing emotions.
Teenagers (12–17)
In teenagers, challenges may involve social struggles, emotional ups and downs, academic pressure, and feeling misunderstood.
Adults (18)
In adults, ADHD may look like poor time management, difficulty staying organised, forgetfulness, or burnout from constant overcompensating.
Many adults with ADHD grow up undiagnosed, especially women and girls, whose symptoms were often missed or mistaken for anxiety or mood issues.
What is involved in an ADHD Assessment?
Our ADHD assessments are comprehensive, neuro-affirming, and designed to be validating and accessible. The process is rigorous, compassionate, and designed to explore the full picture of how ADHD may be impacting the individual. We offer home-based assessments, so you or your child / loved one can feel as comfortable and supported as possible throughout the process.
Pre-assessment telephone consultation:
A 20-minute discussion to understand your goals, history, and any immediate concerns. This helps us tailor the assessment to your needs and prepare for the visit.
Screening questionnaires:
Prior to the assessment, we may ask you (and/or your child, depending on age) to complete one or more screening questionnaires. For school age children we will also provide screening questionnaires to be completed by school or the provider of their education.
These tools help us gain additional insight into the key facets of ADHD such as attention, concentration, impulsivity and hyperactivity as well as social, and emotional patterns. The type of questionnaire used will depend on age and profile, and we will explain this during the telephone consultation.
In-home assessment session (same day):
Our clinician will visit your home to complete the full assessment over several hours. This includes:
- Informal interaction and discussion to understand lived experience, sensory needs, and strengths
- A detailed developmental history (with the individual and/or parent/carer)
- The Young / DIVA – 5 diagnostic Interview for ADHD. (A structured diagnostic interview assessment designed specifically for evaluating ADHD in both children and adults).
Diagnostic report and feedback session:
Within 3 weeks from the assessment you will receive a 60-minute feedback session (online) and this will walk you through the report, findings, answer questions, and provide tailored recommendations and next steps. The comprehensive report will then be sent to you straight after the session.

Frequently Asked Questions
Do you offer ADHD medication or titration?
No. As a psychology-led service, we do not prescribe medication. However, we will provide you with a diagnostic report that you can share with your GP or psychiatrist to support access to medication. We always recommend you speak to your GP before booking an assessment to see if they will accept this arrangement if medication is something you might want to consider in the future.
How long does the assessment take?
The in-home assessment takes approximately 4 – 6 hours, depending on the individual’s age, communication style, and need for breaks. We aim to complete all in-person components in a single day to minimise disruption and reduce stress. Your full report will be provided within 3 weeks, directly after the feedback session.
Why do you offer assessments at home?
Many people feel more relaxed and themselves in their own space, especially those individuals with ADHD. Home-based assessments allow us to see more natural behaviours and create a more comfortable, less clinical experience. It’s ideal for children, adults who find more formal settings anxiety provoking, or those who mask heavily in formal settings.
What happens during the home visit?
Our clinician will carry out a structured but friendly assessment, including:
- A developmental history (with the individual and/or parent/carer)
- The DIVA – 5 assessment interview (a structured specialist interview for ADHD)
- Observations and informal discussion
We will take breaks as needed and move at a comfortable pace. The environment is kept calm, respectful, and person-centred.
What screening tools or questionnaires will I need to complete?
Depending on age and needs, we may ask you to complete one or more brief questionnaires before the assessment. For school age children we also require their school or educational setting to complete a set of questionnaires (typically these are the Connors questionnaire and the SNAP – IV parent / teacher questionnaire). We will explain exactly what is needed during your initial telephone consultation.
We will take breaks as needed and move at a comfortable pace. The environment is kept calm, respectful, and person-centred.
What is the DIVA – 5?
DIVA-5 stands for Diagnostic Interview for ADHD. It is a structured diagnostic ADHD assessment designed specifically for evaluating ADHD in both children (the Young DIVA – 5) and adults. Developed by experts in the field, including researchers and clinicians, this tool is tailored to address the unique challenges and manifestations of ADHD in both children and adults.
Can you assess for co-occurring conditions like Autism, anxiety, or learning differences?
While our standalone ADHD assessments focus on ADHD, we are highly experienced in recognising signs of co-occurring conditions such as:
- Autism
- Learning Disability
- Anxiety and mood differences
- Sensory processing challenges
If we observe traits consistent with another neurotype during the assessment, we will:
- Note this in your report
- Provide thoughtful commentary on how these traits may be impacting day-to-day life
- Offer clear, tailored recommendations for further assessment or support.
Our goal is to see the whole person, not just a diagnosis, and to help you find clarity and direction, whatever your support needs may be.
Do I need a referral?
No referral is required. You can self-refer at any time. However, we’re happy to collaborate with your GP, NHS professionals, or school.
Will a diagnosis help?
For many people, a diagnosis brings relief, clarity, and a deeper understanding of themselves or their child. It can open doors to support, accommodations, and connection with others. We also provide practical recommendations for school, work or family settings based on the outcome.
Can my child be assessed even if school hasn’t raised concerns?
Yes. Many children with ADHD compensate well in structured environments like school but struggle at home. We take input from both settings to build an accurate picture.
Can schools or employers use your report?
Yes. Our reports are detailed and professional, and are often used to support SEN provision, EHCP applications, University disability services, or workplace accommodations.
What if the outcome is not ADHD?
If the assessment does not indicate ADHD, we will still provide a detailed report outlining observations and possible next steps for further support (e.g. Autism, anxiety, trauma-informed care). We aim to make the process helpful regardless of the outcome.
Is the assessment suitable for adults and late-diagnosed individuals?
Yes. We regularly assess teenagers and adults who may be seeking a diagnosis later in life. Our process takes into account masking, burnout, and emotional regulation difficulties, which are common among those lately-diagnosed with ADHD (especially women and those from underrepresented backgrounds).
How can I prepare for the ADHD assessment?
Preparation is simple! Generally, it’s useful to:
- Find a quiet, comfortable space at home for the clinician’s visit
- Gather any relevant reports, school records, or previous assessments if you have them
- Think about key developmental milestones and challenges you want to discuss
- Have favourite toys, books, or activities ready (especially for children)
- Talk with your child about the visit in a calm, positive way — reassuring them that the clinician is there to help and that there’s no ‘right’ or ‘wrong’ answer
- Complete any pre-assessment questionnaires we send
Feel free to ask us any questions before the day — we’re here to support you every step of the way.
What support is available while waiting for my assessment report?
Waiting for assessment results can be a stressful time. Here are some things that might help:
- Keep a journal or notes on your experiences, feelings, and any questions you want to ask at the feedback session
- Reach out to peer support groups or local ADHD organisations for community and advice
- Consider self-help resources focusing on wellbeing, sensory needs, or social skills (we can recommend trusted materials)
- Maintain routines and strategies that support comfort and reduce anxiety
- Contact us anytime if you have urgent concerns or need guidance during the waiting period
Remember, the wait is temporary, and we’re committed to providing timely, thorough feedback to help you move forward with confidence.
What causes ADHD?
For most people with ADHD, the condition is caused by a combination of genetic and environmental factors.
Genetics – The genetic factors that lead to someone developing ADHD are generally made up of lots of small genetic differences rather one single gene.
Environmental factors – environmental factors can include things like:
- difficulties when you were in the womb
- birth complications
- exposure to toxins
- nutritional deficiencies
- brain injury.
Studies have shown that the genetic and environmental factors leading to ADHD are also found in other common mental and physical health conditions.
Is there a gender difference in ADHD?
ADHD is more commonly diagnosed in boys than in girls. However, in adults the diagnosis of ADHD in men and women is more equal. This might be because, as children, boys are more likely to show hyperactive and impulsive symptoms, which are more noticeable.
When it comes to diagnosis, girls and women might be more likely to:
have undiagnosed ADHD; not be referred for assessment for ADHD; receive an incorrect diagnosis of another mental health or neuro-developmental condition.
Is ADHD becoming more common?
In recent years, ADHD services across the UK have seen an increase in the number of referrals. There are lots of possible reasons for this, including:
• more widespread awareness of ADHD amongst the general public and healthcare professionals
• the COVID-19 pandemic, which has meant that working and educational environments have changed. This may have made ADHD behaviours more noticeable.
More people being referred for ADHD assessments is a positive thing, because it means that those who do have ADHD can receive the support they need. Those who find out that they don’t have ADHD, but have related support needs, can also get help.
We are aware that some people incorrectly say that ADHD is ‘fashionable’ or ‘made up’. In fact, the first description by a doctor of a disorder resembling ADHD was in the 18th century. The name of the disorder has changed over time but the same challenges are described that we recognise as ADHD today.
There is agreement between health care professionals and scientists around the world that ADHD is a valid diagnosis. There are clear guidelines describing how ADHD is diagnosed, and how it should be assessed, supported and treated.
When would you notice ADHD and does it change over time?
ADHD can start to show itself at an early age, however this is often first noticed when someone is at school. However, some people might not experience challenges until adulthood, or these challenges might not be noticed until they are much older.
Although people with ADHD share common, ‘typical’ symptoms, ADHD can look different from person to person. What ADHD looks like can depend on a person’s:
• background
• personality
• fit with their environment
• level of support and structure
• positive and negative life experiences
• stage of life
Hyperactive and impulsive symptoms tend to be more common in childhood and be less of a challenge for some people over time. Inattentive symptoms tend to become more of an issue in teenage years and adulthood.
Growing up
Usually, as young people grow up, they experience more challenges and receive less support. For example, if someone has lived at home and had lots of support, their ADHD might not cause them problems until they move out of home.
Young adults with ADHD often face new challenges, such as:
• work or education
• living independently
• relationships
• finances
In adulthood
Throughout life, new challenges like parenthood might further increase a person’s overall level of stress. This can mean that their ADHD causes more challenges as they get older.
As the overall level of demand and stress increases, people with ADHD are more likely to struggle to keep up. When this happens, they can become overwhelmed and unwell. This can be avoided through appropriate support.
