The assessment explained

What Is an Adult ADHD Assessment?

There is no single blood test or brain scan for ADHD. A diagnosis is made through a detailed clinical assessment: a structured diagnostic interview covering your current symptoms, your developmental history back to childhood, and the impact your symptoms have on work, relationships and daily life.

Your Consultant Psychiatrist will also screen for co-existing conditions that can mimic or accompany ADHD — such as anxiety, depression and autism — so you receive an accurate diagnosis rather than a label that misses the full picture. ADHD was formerly known as ADD (attention deficit disorder); today, clinicians diagnose ADHD in three presentations: predominantly inattentive (what many people still call ADD), predominantly hyperactive-impulsive, and combined.

Recognise yourself?

Do I Have ADHD? Signs It May Be Time for an Assessment

Many adults reach us after years of feeling that something has been harder for them than it seems to be for everyone else. You may recognise yourself in some of these patterns:

Inattentive symptoms

  • Difficulty sustaining focus on work, reading or conversations; frequent careless mistakes
  • Chronic procrastination, missed deadlines and unfinished projects
  • Losing things, forgetting appointments, struggling to organise everyday tasks

Hyperactive and impulsive symptoms

  • Restlessness, difficulty relaxing, feeling “driven by a motor”
  • Interrupting others, impulsive decisions or spending, talking excessively
  • Low frustration tolerance and mood swings

ADHD is frequently missed in adults — especially in women, whose symptoms more often present as inattention, anxiety or exhaustion from “masking” rather than visible hyperactivity. Read more about ADHD in women.

Not sure whether an assessment is right for you? Take our free five-minute adult ADHD self-test. It is a screening tool rather than a diagnosis, but it will give you a clear indication of whether a full assessment is worthwhile.

What is adult ADHD?

Attention-deficit/hyperactivity disorder (ADHD), formerly known as ADD or Attention Deficit Disorder, is a neurodevelopmental disorder commonly characterised by symptoms of hyperactivity, inattentiveness, impulsivity.

It can affect both adults and children, and due to the range and subtlety of symptoms it can present with, it is not always easy to notice or diagnose.

Do I have adult ADHD?

If you were diagnosed with childhood ADD/ADHD, the chances are that you have carried at least some of the symptoms into adulthood. But even if you were never diagnosed with ADD/ADHD as a child, that does not mean that you cannot be affected by the symptoms as an adult.

Many people with undiagnosed childhood ADHD will seek an ADHD diagnosis and treatment in adulthood because that is when the symptoms start to affect their lives in different, and often more troubling and detrimental, ways.

Bespoke Assessment and Diagnosis for Adult ADHD

Adult ADHD assessment

Prior to the appointment, we will ask you to provide some information. This will include a simple symptom checklist, registration forms and collateral information forms. This will help the doctor to get a better objective understanding of how your ADHD symptoms may have affected you throughout your life.

We advise that you are as open and transparent as possible about your symptoms and the impact they have had on your life, as this will help us to devise an effective treatment plan.

Your assessment will be conducted by one of our specialist ADHD Consultant Psychiatrists. You are more than welcome to bring someone with you to the appointment if you wish.

Following the assessment, you will receive a report from your Consultant Psychiatrist outlining the diagnosis and bespoke treatment plan details.

Adult ADHD diagnosis

Accurate diagnosis is a crucial part of managing ADHD, and while there is no single physical test that can determine whether a person has ADHD, a diagnostic analysis and structured clinical assessment performed by an experienced Consultant Psychiatrist can provide accurate results.

Diagnosis will be based on the number and frequency of the symptoms, as well as the amount of time the client has been experiencing them. The doctor will also be able to determine whether these symptoms have been caused by other coexisting disorders, such as anxiety or depression.

Throughout the process, you will be provided with guidance and support from our expert clinicians. You will also have freedom of active participation in your ADHD treatment and management plan. The sooner you receive an accurate diagnosis and start a bespoke treatment plan for adult ADHD, the more likely the chances will be for optimal symptom management, and the more freedom and confidence you will have to make positive life changes.
