ADHD, or Attention-Deficit/Hyperactivity Disorder, is a condition that affects both children and adults. It can make it hard to pay attention, control impulses, and sit still. People with ADHD may struggle with staying focused, organizing tasks, and impulsiveness. An ADHD assessment with the right treatment can lead people towards the support and help they need.

Identifying ADHD in adults

ADHD can present with a wide range of signs and symptoms. Although many people with ADHD may experience similar struggles, each person has their own distinct difficulties. It is important for an ADHD diagnosis to be conducted by professionals who possess up-to-date expertise and knowledge in this field.



ADHD can make it difficult to maintain attention and focus on tasks, often leading to difficulty staying on track


People with ADHD often struggle with impulsivity, finding it challenging to think before acting


ADHD can affect the ability to be organised, with difficulty structuring tasks, managing time effectively, and keep track of belongings


Many people with ADHD experience anxiety, as the constant struggle with attention and organization can create a sense of unease and overwhelm

It is very common for symptoms of ADHD to first appear in early childhood and persist into adulthood. The way that these symptoms present and interfere with a person’s life may change as a person gets older.

While it is common to receive an ADHD diagnosis as a child, this is not always true. As people get older they may notice certain ADHD traits affecting them more, and an adult ADHD assessment with suitable treatment can make a positive difference.


While each person with ADHD is unique, it can be useful to listen to the feedback of other people who have been through similar experiences. The testimonials below are a small selection from several patients who very kindly agreed to feature in this section (certain personal details have been removed).

I am incredibly grateful for the autism assessment with Dr Maritan, as it led to a life-changing discovery. While I initially expected to be diagnosed with autism, the doctor went above and beyond in her evaluation and identified that I had bipolar disorder. Her expertise and attention to detail allowed for an accurate diagnosis, which was pivotal for me. The whole team’s compassionate support and personalised advice have guided me towards effective treatments and strategies. Although the result was unexpected, it ultimately set me on the right path. I highly recommend that anyone seeking clarity and support gives it a shot, as it can genuinely make a difference.
Before my assessment, the only help I ever managed to get was a prescription for antidepressants. I think my GP did want to help, but they told me they’ve had patients on waiting lists for over 2 years and now with Covid it’s even worse. It was a lot of money, but the assessment with Harley Psychiatrists led to an autism diagnosis that changed everything. I have finally started therapy that’s actually tailored to my needs, and I am learning to stop blaming myself for “not trying hard enough”. The clinic’s understanding and guidance have empowered me to embrace my strengths and manage my challenges effectively. I highly recommend their assessments to anyone seeking the right support and understanding.
The assessment at Harley Psychiatrists was done at a complete low point in my life, and to be honest I didn’t think it would change anything. I was so wrong and I’m so glad my parents talked me into it. Dr Nigel did diagnose me with Asperger’s but also asked me to come back for an ADHD assessment too, and it turns out I have both. With Dr Nigel’s support, I started treatment for ADHD, and it has made a big positive difference in my life. I got a shared care agreement so I get prescriptions from my GP and the whole process has made me feel like a different person.

Taking the first step towards an ADHD assessment can feel daunting, but accessing diagnosis and treatment from an expert Consultant Psychiatrist can make a real difference.

Your psychiatrist will take into account factors such as your physical health, family history and impact of symptoms. It is important for ADHD assessments to be bespoke and developed around your specific difficulties. During your assessment, particular attention will be given to comorbidities – related conditions (such as anxiety or mood disorder) so that the diagnosis is made as accurately as possible.

Once an ADHD diagnosis is given, your psychiatrist will consider your individual needs when suggesting any kind of treatment plan to manage your specific symptoms. This ADHD treatment plan will be personalised to you. Although an “ADHD cure” doesn’t exist, with appropriate medical treatment and psychological support it is possible to lessen the impact of many associated symptoms.

Common questions and answers

Types of ADHD

ADHD encompasses three main types: predominantly inattentive type, predominantly hyperactive-impulsive type, and combined type.

The predominantly inattentive type is characterized by difficulties sustaining attention, being easily distracted, and struggling with organisation and follow-through.

The predominantly hyperactive-impulsive type involves excessive physical activity, restlessness, impulsivity, and difficulty with self-control. The combined type presents a combination of symptoms from both inattentive and hyperactive-impulsive types.

It is important to note that ADHD is a spectrum, and individuals may exhibit symptoms that fall within different types or experience symptom variations over time. A comprehensive assessment by a Consultant Psychiatrist specialising in ADHD is crucial to determine the specific type and tailor appropriate treatment and support.

By recognizing the diverse nature of ADHD, we can appreciate the unique strengths and challenges each person brings and therefore their support and interventions can be tailored accordingly.
