Adult ADHD assessment by video: what to expect

Telepsychiatry.co.uk team · 20 August 2026

Many adults seek an ADHD assessment after years of wondering why focus, organisation or restlessness have been such a struggle. NHS waiting lists for adult ADHD assessment are long in many areas, and more people are choosing a private assessment by video. Here’s what the process usually looks like.

Why ADHD assessment suits telepsychiatry

An adult ADHD assessment is built on a detailed clinical interview, structured questions and a careful look at your history from childhood onwards. None of that requires being in the same room. Many people with ADHD also find it easier to fit a video call into a busy week than to travel to a clinic.

Before the assessment

You may be asked to complete questionnaires beforehand. It also helps to gather:

  • Childhood evidence. School reports, comments from teachers, or anything that shows how you were as a child. ADHD starts in childhood, so this matters.
  • Someone who knew you young. A parent, older sibling or relative who can describe your early years can be valuable. Ask whether they can be available or share their observations.
  • Examples from adult life. Think about work, study, relationships, money, driving and daily organisation.
  • Your health background. Other mental health conditions, sleep, alcohol and drug use, and physical health – including any heart problems – are all relevant.

During the assessment

The initial ADHD assessment with Happy Clinic lasts around 60 minutes. Your psychiatrist will explore:

  • your current difficulties with attention, impulsivity and restlessness;
  • how long they’ve been present and how they affect different areas of life;
  • other explanations or conditions that can look similar or co-exist, such as anxiety, depression, autism or sleep problems.

Sometimes a clear conclusion is reached at the first appointment; sometimes a further review is needed.

If ADHD is diagnosed

Your psychiatrist will talk through options, which may include medication, practical strategies and support. If medication is appropriate, treatment usually starts with a low dose, adjusted gradually in titration reviews (20 minutes each). You’ll typically be asked to monitor your blood pressure, pulse and weight during this time.

ADHD medication is only prescribed where it is clinically appropriate and safe – a diagnosis doesn’t automatically mean medication.

Moving care to your GP

Once your dose is stable, your psychiatrist may propose a shared care agreement with your NHS GP, so that routine prescribing can continue through the NHS with specialist oversight. Your GP practice decides whether to accept. Read more in our guide to shared care.
