Accessible ADHD assessments for adults. Get a clear diagnosis and the support you need to thrive personally and professionally.

Why get an ADHD assessment? 

Getting assessed as an adult can be a transformative step. Many people go through life struggling with focus, organisation, time management or emotional regulation without realising ADHD could be a factor. Understanding the root of these challenges can bring a huge sense of relief and clarity. A formal diagnosis can help you:

Understand symptoms

Gain clarity on personal challenges and work with ADHD professionals to create strategies to manage symptoms effectively.

Access to treatment and support

Find the right combination of therapy, coaching and/or lifestyle changes to improve quality of life.

Get workplace and academic adjustments

A formal diagnosis enables employers and schools to make reasonable accommodations to better support people with ADHD.

Empower yourself with peace of mind

Work with a specialist to remove the uncertainty, understand yourself better and move forward with confidence.

Signs and symptoms of ADHD in adults 

Everyone’s experience is different, and it’s not always easy to recognise ADHD, especially as symptoms can overlap with other conditions.

Struggling to stay focused

People with predominantly inattentive ADHD may have trouble paying attention, finishing tasks and staying organised – even when they’re trying their best.

Feeling restless or can’t sit still

People with hyperactive-impulsive ADHD often find it hard to stay still or slow down. They may act without thinking, talk more than others, interrupt unintentionally, or struggle to wait their turn.

Impulsivity and trouble concentrating

People with combined ADHD often experience a mix of inattentiveness and hyperactivity–impulsivity. They may struggle to focus and complete tasks, while also feeling restless or acting on impulse.

Frequently asked questions

How do I know if I have ADHD as an adult?

Common signs include:

  • Difficulty concentrating or completing tasks
  • Impulsivity and poor time management
  • Disorganisation and forgetfulness
  • Mood swings and emotional sensitivity
  • Restlessness or fidgeting

If these symptoms impact daily life, a professional assessment can offer clarity and help you move forward.

Who is involved in the assessment

Our adult ADHD assessments are conducted by a specialist clinician trained in ADHD and neurodevelopmental assessments. You may also be asked to involve someone who knows you well (e.g. your partner, friend, colleague) to help build a full picture. With your consent, workplace feedback may also be requested if relevant.

Can I get an ADHD diagnosis online?

Yes. Our services are delivered online, designed to fit around your life and schedule. With Xyla, you’ll have access to trusted, thorough assessments conducted by expert clinicians. With no long waiting times, you can start the process and receive your assessment within days, not months.

Is the diagnosis valid for workplace adjustments?

Yes. A formal diagnosis from Xyla can support reasonable accommodations under the Equality Act 2010.

Will I be able to access medication?

Following an ADHD diagnosis, medication may be recommended if appropriate. While we don’t currently prescribe medication, we’re working towards offering this soon. In the meantime, we provide clear guidance on next steps, including how to explore medication options with your GP or a specialist.

As part of our comprehensive and personalised approach to care, we also offer post-diagnostic support pathways focused on wellbeing, lifestyle and education.

How long does does an adult ADHD assessment take?

Our remote clinical assessment for ADHD usually takes around 60 minutes, followed by a separate 30-minute feedback session. From your initial consultation to receiving your diagnosis, the full process can typically be completed within 14 days. Timeframes may vary slightly depending on your availability and individual needs.
