In psychology and neuroscience, executive functions in the brain are a set of fundamental cognitive skills that serve as the mind’s management system, helping us plan, organize, start, monitor, and adjust behaviors to navigate daily life.
These areas are affected by neurodevelopmental disorders like ADHD and autism spectrum disorder (ASD). If you have these disorders (or other conditions that impact executive function), it’s critical to understand how these aspects of your neurobiology interact, especially if you find it hard to cut yourself slack when things go wrong.
This FAQ-style ef blog post explores 14 questions relating to executive function in the brain:
Executive functions are a set of mental skills that help us start, sustain, and adjust our actions and thoughts in daily life.
Executive functions are primarily handled by the prefrontal cortex, in the frontal lobe of the brain.
This region connects to other higher-level brain systems involved in memory, attention, emotion, and motor control, coordinating them so you can act effectively in complex, changing situations.
The brain finishes developing in the mid twenties, and much of that final maturation takes place in the frontal lobe. But experts believe we fully develop our executive function skills by age 29.
While this may be true, since executive functions are skills, so by definition, you can continue to improve and strengthen them.
Executive functioning psychology refers to the study of how our brain’s higher-level mental processes help us manage, control, and direct our thoughts, actions, and emotions to achieve goals.
Executive function is often assessed to understand difficulties people may have, especially in conditions like ADHD, autism, traumatic brain injury, and mood disorders. (Here’s an online executive function test).
High executive function means having strong skills in managing thoughts, actions, time, and emotions to achieve goals, especially in complex, unpredictable situations.
High executive function helps people turn intentions into effective action and supports:
Poor executive function means that the brain’s self-management system isn’t working as efficiently or consistently as it should.
Poor executive functions in the brain isn’t about laziness or lack of willpower; it’s that your mind isn’t coordinating these mental skills as effectively as you need in that moment.
Poor executive functions in the brain can affect:
Executive dysfunction refers to poor executive function and difficulties managing these mental skills.
Executive function disorder (EFD), also called executive function deficit, describes ongoing challenges with these skills. While not a formal medical diagnosis, EFD is common in conditions like ADHD and autism spectrum disorder (ASD).
In EFD, the brain’s coordination of memory, emotion, and motor systems is less efficient, making it harder to bridge the gap between intention and action.
Executive dysfunction can show up as:
Remember: It’s not about laziness or lack of willpower; it’s about how the brain is managing (or not managing) these essential skills.
Executive dysfunction can feel like knowing what you want or need to do, but being unable to make it happen, no matter how hard you try. It’s the invisible gap between intention and action, and it can feel deeply frustrating, confusing, and exhausting.
People often describe executive dysfunction as:
Executive functions in the brain aren’t fixed.
Your level of executive function access can vary depending on stress, sleep, health, or environment. And even people with typically high executive function may struggle in certain situations or under pressure.
Poor executive functions in the brain can happen temporarily during periods of extreme stress, sleep deprivation, or illness — even in people without a diagnosis.
Executive dysfunction is common in conditions like:
ADHD and related conditions often involve executive function challenges, but with the right supports (like planners, tools, coaching, and routines), executive function skills can be strengthened over time.
Here are five common categories of supports for executive functions in the brain:
Since the brain’s internal system may not be working as reliably, external tools provide structure:
Example: ADHD-friendly planners (like your Layouts A, B, C) offer both structure and flexibility — key for people with executive dysfunction.
Large or complex tasks can overwhelm the executive system. Breaking them down:
Tip: Write down micro-steps so you can check off progress as you go.
Establishing predictable routines reduces the demand on executive systems.
Daily review prompts like “What went well today?” or “What made this task easier?” build self-awareness. This helps you adjust your strategies without shame.
Tip: Layout C’s reflection section is designed exactly for this!
Executive dysfunction doesn’t mean you can’t succeed — it means you may need more tools and external structure to support the incredible ideas, intentions, and goals you already have.
With the right strategies, executive functioning can be supported, strengthened, and celebrated.
