For the last decade, Sam Thompson has appeared on shows like Made in Chelsea and Celebs Go Dating. But off camera, Sam has spent his whole life struggling with inattention, disorganisation and hyperactivity - impacting not only himself, but also his friends, family and partner Zara McDermott.
After turning 30, Sam wants to finally figure out if these issues are quirks of his personality, or if they're symptoms of ADHD. An estimated 1.9 million adults in the UK have ADHD, the majority of whom are believed to be undiagnosed.
Sam will find out if he's one of them. He soon realises he's part of a wider trend. A growing number of young people are taking to social media to speculate if they have undiagnosed ADHD, with #ADHD racking up billions of views on TikTok alone.
As Sam explores the subject more closely, he grapples with whether to seek out a formal diagnosis, meets others who have been in a similar situation, and examines how therapy and medication can impact day-to-day life with ADHD.
Sam Thompson: Is This ADHD? airs Monday 08th May at 9pm on E4.
