Executive functions (EFs) are the brain’s self-management skills — the mental abilities that help us plan, focus, organize, remember, and regulate ourselves. Executive functions help us to meet goals, manage time, follow routines, and adapt when things don’t go as expected.
Executive functions are a set of interconnected skills that develop gradually throughout childhood and adolescence.

Executive functions develop gradually through childhood, adolescence, and into young adulthood — typically until around age 25. Because no child or teenager has a fully developed set of skills, differences in organization, time management, emotional regulation, and task initiation are completely normal.
Everyone has a unique profile of executive strengths and challenges, and these can shift day to day based on sleep, stress, and other factors. For individuals with executive function deficits, however, the struggles are more consistent and impactful. They show up across home, school, and social life, not just during busy or stressful times.
These difficulties are not about motivation or effort. They reflect real differences in how the brain’s self-regulation systems develop (Wang et al., 2025). With understanding, structure, and targeted support, young people can strengthen these skills and build systems that help them thrive.
ADHD can be understood as a delay or deficit in executive functioning (Barkley, 2024). These difficulties affect how the brain manages attention, behaviour, and emotions. In other words, ADHDers often know what to do but have trouble doing what they know — especially when tasks are boring, complex, hard or emotionally charged.
