This information is provided directly by researchers, and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information. In some summaries, you may come across links to external websites. These websites will have more information to help you better understand the study.


We are learning more about how our brains work and why people experience the world in different ways. Some of these differences relate to autism and Attention Deficit Hyperactivity Disorder (ADHD). Many people are both autistic and have ADHD. These are neurodevelopmental conditions.

Some people with these conditions experience psychosis, which may involve hearing voices or believing things others do not. This can be frightening. It’s often hard to get the right care, because the signs of psychosis and neurodevelopmental conditions can look similar. For example, someone might prefer being alone or have unusual thoughts. These overlaps can lead to delays in diagnosis or the wrong kind of support.

In earlier work, I found that people with autism and/or ADHD who experience psychosis often go into hospital at a younger age and stay longer than others. Some experts believe that ADHD might affect how psychosis develops in people who are both autistic and have ADHD, but we don’t yet know for sure.

In this study, I will explore whether ADHD changes how psychosis affects people who are autistic, have ADHD, or both. The aim is to help health and care teams give better support, so people get the help they need in the way that works best for them.

I will invite people aged 18 and over who have had a first episode of psychosis (FEP). I will recruit people from NHS services at several sites.

People taking part will complete ADHD questionnaires, which usually take around 60 minutes. I will also look at their health records to learn more about their psychosis. Once they finish the questionnaires, they won’t need to do anything else.

The National Institute for Health and Care Research (NIHR) is funding this study. We will keep all personal information private and use it only for research.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.

Observational

Observational type: Cross-sectional;



You can take part if:



You may not be able to take part if:


1. FEP only group: RAADS-14 score > = 14 (59) and ASRS score of > = 17 as otherwise this group may be autistic and/or ADHD (60) 2. Lack of capacity to consent. Please note, these groups (FEP, FEP+ADHD, FEP+ASC, FEP+ADHD+ASC) are not treatment arms but have been defined solely to enable sufficient recruitment and meaningful cross-group analysis within a cross-sectional design. While most participants will be allocated clearly based on diagnosis or screening, a small number may fall near thresholds or present mixed indicators. In such cases, I will seek supervision and LEAP input to ensure appropriate grouping.
