Expert ADHD & Mental Health Assessments

A private ADHD assessment is a comprehensive evaluation carried out by a qualified mental health professional to determine whether you meet the criteria for Attention Deficit Hyperactivity Disorder (ADHD). At Harley Street Mental Health, our private adult ADHD assessments in the UK include an in-depth clinical interview, evidence-based diagnostic tools such as the DIVA 5.0, and a review of developmental history and current symptoms. Assessments typically explore how ADHD symptoms impact areas such as work, education, relationships, and daily functioning.

Choosing a private ADHD assessment offers faster access to diagnosis and treatment compared to NHS waiting times. Following the assessment, a formal diagnostic report is provided, and if a diagnosis is confirmed, we offer guidance on ADHD treatment options, including medication, therapy, and lifestyle strategies.

Yes, all of our private ADHD assessments at Harley Street Mental Health are fully compliant with the National Institute for Health and Care Excellence (NICE) guidelines for the diagnosis and management of ADHD. We go beyond the standard requirements by also following the Associated Quality Assured Standards (AQAS) developed by UK adult ADHD specialists. This ensures that our assessments are not only evidence-based but also reflect best practices in the field.

Our clinicians use validated diagnostic tools such as the DIVA 5.0 and follow a structured clinical interview format that meets and exceeds NICE standards. This comprehensive approach includes a detailed review of your developmental history, current symptoms, and the impact of ADHD across different areas of life, including education, work, relationships, and everyday functioning.

By exceeding national guidelines, we aim to provide the highest standard of ADHD care available privately in the UK.

ADD (Attention Deficit Disorder) and ADHD (Attention Deficit Hyperactivity Disorder) refer to the same condition, but the terminology has evolved. ADHD is the current medical term used to describe individuals who have difficulties with attention, impulsivity, and/or hyperactivity, even if hyperactivity isn’t a prominent symptom.

Historically, ADD was used to describe individuals who had trouble with attention and focus but did not show signs of hyperactivity. Today, this would be diagnosed as ADHD, Predominantly Inattentive Presentation, one of three recognised subtypes under the modern ADHD diagnostic criteria.

At Harley Street Mental Health, we assess for all presentations of ADHD, including:

• Predominantly Inattentive Type (formerly known as ADD)
• Predominantly Hyperactive-Impulsive Type
• Combined Type

Yes, we have a dedicated team of CAMHS consultant psychiatrists that can diagnose and treat ADHD in individuals aged under 18
