Simon Pegg has revealed that he was recently diagnosed with attention deficit hyperactivity disorder, saying the diagnosis brought him a sense of relief.
The Mission: Impossible and Shaun of the Dead star discussed the diagnosis on the I’m ADHD! No You’re Not podcast, explaining that he received it only recently. For Pegg, having a clearer explanation for patterns he had experienced over the years helped put parts of his life into a new context.
The 56-year-old actor has spoken candidly in the past about personal challenges, including addiction and recovery. His latest comments continue that openness, this time focusing on neurodiversity and the experience of receiving an ADHD diagnosis in adulthood.
Adult ADHD has become a more visible subject in entertainment as public figures discuss late diagnoses and how they affect work, relationships and self-understanding. Pegg’s comments are notable because he described the diagnosis not as a setback but as useful information that helped make sense of his experiences.
Pegg remains active across film and television, with a career that ranges from British comedy to major Hollywood franchises including Mission: Impossible and Star Trek. His ability to move between writing, comedy and action roles has made him one of the most recognizable British performers of his generation.
By speaking publicly about the diagnosis, Pegg joins a growing group of performers who have helped bring adult ADHD into mainstream conversation without reducing it to a celebrity label.
