How adults get diagnosed with ADHD in the UK
In the UK, an adult ADHD diagnosis should be made by a specialist, such as a psychiatrist or a suitably qualified specialist nurse or psychologist, following national guidance from NICE.
The usual first step is to see your GP. They will ask about your difficulties, check for other possible explanations, and, if appropriate, refer you to an adult ADHD service. Some areas have their own local criteria, so the process can vary.
An assessment usually involves a detailed conversation about your life now and in childhood. You may be asked to complete questionnaires before or during the appointment. Many services also ask for information from someone who knew you as a child, such as a parent or older sibling, or for old school reports. Do not worry if these are not available — clinicians are used to working without them.
The specialist will look at whether your difficulties started in childhood, whether they are present in more than one area of life, and how much they affect you. They will also consider other conditions, such as anxiety, depression or autism, which can occur alongside ADHD or look similar.
At the end, you should receive a written report. If you are diagnosed, it will usually include recommendations, such as medication, psychological support or adjustments at work.
Whatever the outcome, an assessment can give you a clearer understanding of yourself. And if you are not diagnosed, that does not mean your difficulties are imaginary. You still deserve support for the things you find hard.
