An adult ADHD specialist matched to your requirements and personality.

An adult ADHD assessment is more than a tick‑box exercise – it’s a chance to understand how your brain works and why everyday tasks can feel harder than they “should”. With Augmentive, the pathway is straightforward and transparent. Assessments start from £650, with follow‑up appointments (if necessary) from £150. Most people have around three follow‑ups over three to six months, but this can vary depending on your needs and how you respond to treatment. A full private adult ADHD assessment typically lasts around 1.5–2 hours and is most often carried out via secure online video, with in‑person options available in some locations. You’ll meet a psychiatrist or other ADHD‑experienced clinician, who will review your history, use recognised ADHD rating scales and consider any other conditions that may be involved. Afterwards, you receive clear verbal feedback and a written report, along with personalised recommendations for treatment and support. Your diagnosis becomes an action plan, not just a label – so you know exactly what your next steps are.

Symptoms of adult ADHD

Adult ADHD is defined by the NHS as a neurodevelopmental condition that affects attention, organisation and impulse control. There is a range of symptoms. You might find it hard to start or finish tasks, lose track of time or everyday items, or feel your focus pulled by every notification or noise. Some people swing between feeling stuck and then hyper‑focussed for hours, talk a lot, act or spend on impulse, or constantly feel “on the go”. ADHD can also be easier to miss in women and in people who have learnt to mask their difficulties, which is why a specialist adult ADHD assessment is so important.

What happens in an adult ADHD assessment?

An adult ADHD assessment with Augmentive is structured and thorough, but designed to feel as straightforward as possible. Before you meet, you’ll usually complete short questionnaires. You’ll then have a 1.5–2 hour appointment with a specialist clinician, most often via secure online video, where they take a detailed history, explore your current difficulties and use recognised ADHD rating scales. They will also consider other conditions, such as anxiety, depression or autism, that can overlap with ADHD. At the end, your clinician explains whether you meet diagnostic criteria for adult ADHD and talks you through clear next steps, whatever the outcome.

Types of adult ADHD

Clinically, ADHD in adults is described in three main presentations: predominantly inattentive, predominantly hyperactive–impulsive, and combined. Inattentive ADHD is more about focus, memory and organisation; hyperactive–impulsive ADHD is more about visible restlessness and acting quickly without thinking; and the combined presentation includes traits from both. In real life, many adults recognise themselves in more than one pattern, and symptoms can shift over time or in different settings, so a personalised assessment looks at how ADHD shows up for you rather than forcing you into one box.

Adult ADHD treatment & support

Treatment for adult ADHD is usually a mix of approaches, tailored to your needs. Medication can help with attention, impulsivity and hyperactivity where it’s clinically appropriate, and your specialist will explain the options and monitor how you respond. Talking therapies and ADHD‑informed coaching can support emotional regulation, routines and self‑esteem, while practical adjustments at work or university and tools for organisation and time‑management make day‑to‑day life easier. When things are stable, your specialist may write to your GP to explore a shared‑care agreement so, where local services allow, ongoing prescriptions can be managed through the NHS.
