Why Your Brain Sometimes Feels Like It's Working Against You: Executive Functioning & ADHD Explained

Written By carrie gensler

Let me ask you something. How many tabs do you have open right now on your browser, and in your brain? If you have ADHD, the answer is probably "too many," and closing them feels basically impossible. That's not a focus problem or willpower problem, it's an executive functioning problem. And once you understand what that actually means, a lot of things about the way your brain works will finally start to click. Let’s look at a brief overview of what executive functioning is, how it shows up, and how it changes across the life span.

So... What Is Executive Functioning?

Think of executive functioning as your brain's CEO.

It's the set of mental skills that help you plan, start tasks, manage time, control impulses, and keep track of what you're doing and why.

It includes things like:

  • Getting started on tasks (even ones you want to do)

  • Staying focused when things aren't immediately interesting

  • Managing your time and not losing track of it

  • Holding information in your mind while using it

  • Shifting gears when plans change

  • Managing frustration and emotional reactions

Where Does Executive Functioning Live in the Brain?

The short answer: right behind your forehead.

The prefrontal cortex is the part of the brain most responsible for executive functioning. It sits at the very front of your brain and acts as the command center for decision-making, planning, and self-control.

In ADHD brains, this area develops differently. For someone without ADHD the prefrontal cortex (the last area of the brain to develop) would be fully developed around 25/26. With ADHD the prefrontal cortex can develop up to 3 years behind the “typical” timeline. Meaning that a 7 year old might look more like a 3 or 4 year old when it comes to the areas executive functioning plays a role in (emotional regulation, task initiation, self starting, etc.).

Communication between the prefrontal cortex and the rest of the brain relies heavily on dopamine, a chemical messenger that plays a big role in motivation and focus.

When dopamine levels are lower or less regulated (which is the case with ADHD), the prefrontal cortex doesn't fire the way it needs to. That's why so many ADHD strategies, including medication, focus on supporting healthy dopamine (screen time, sugar, tik tok, instagram scrolling are examples of unhealthy dopamine). Healthy dopamine looks like going for a walk, working out, connection with others, sunlight, music, and engaging with your favorite hobbies. These are just a few examples. It's all about giving your brain the fuel it needs to do its job.

What This Actually Looks Like Day-to-Day

  • Task initiation: Knowing you need to do something and genuinely not being able to start — even when the consequences are serious.

  • Time blindness: Feeling like time only exists as "now" and "not now." Missing deadlines even with the best intentions. Being either late or too early for something.

  • Working memory: Forgetting what you walked into a room for, losing your train of thought mid-sentence, or reading a paragraph three times.

  • Emotional dysregulation: Feeling emotions more intensely and having a harder time calming down.

  • Hyperfocus: Getting so locked into something interesting that hours disappear and everything else is forgotten.

These things can make one feel like they are always missing the mark, always falling behind, worthless, and striving to always do better. Especially if you do not understand that something might be working differently in your brain.

Kids vs. Adults: It Shows Up Differently

ADHD doesn't disappear with age but it often changes shape.

In children: executive dysfunction tends to be thought of as loud and visible, but that is not always the case. Some children are visibly hyperactive: running, climbing, blurting things out, unable to sit still. Others are quietly daydreaming, losing track of instructions, or shutting down when faced with a task that feels too big.

Common signs in children include:

·       Explosive frustration over tasks that feel overwhelming to start

·       Losing belongings constantly — water bottles, homework, shoes

·       Difficulty transitioning between activities ("just five more minutes" on repeat)

·       Forgetting multi-step instructions almost immediately

·       Emotional reactions that seem intense or disproportionate

·       Hyper-focusing on preferred activities while completely avoiding others

In Adults: ADHD can look quieter on the surface, but the internal experience can feel even more exhausting. By adulthood, most people have spent years developing workarounds and coping strategies just to keep up. From the outside, they can appear to be managing fine. On the inside, it's a different story.

Common signs in adults include:

·       Chronic procrastination — not laziness, but genuine inability to initiate

·       Difficulty keeping up with responsibilities like bills, appointments, or emails

·       Feeling constantly behind, no matter how hard you try

·       Struggling to maintain relationships due to forgetfulness or emotional intensity

·       Starting many projects and finishing few

·       A persistent sense of underachieving despite being clearly capable

Women and girls especially tend to be missed or misdiagnosed because they often internalize symptoms rather than externalizing them.

What Can Help?

Understanding this is the first step. From there:

  • External structure — calendars, timers, written lists — to replace what the brain doesn't do automatically

  • Body-doubling — working near another person, even virtually, to help get started

  • Tiny first steps — not "clean the kitchen," but "put one dish in the sink"

  • Therapy — particularly working with someone who specializes in ADHD, and understands the unique brain style differences.

  • Medication — which can significantly support dopamine regulation for many people.

  • The Pause Strategy
    When overwhelmed, ask:

    • What’s the next smallest step?

  • Normalize Resetting
    ADHD productivity often works in bursts, not steady output. Build intentional reset points during the day.

  • Self-Compassion Scripts
    Replace self-criticism with supportive language:

    • “My brain works differently.”

    • I need more structure, not more shame.”

  • Work With Your Energy, Not Against It
    Schedule tasks based on brain state:

    • High focus time: deep work

    • Low energy: admin tasks

Understanding executive functioning can help make sense of many of the challenges that come with ADHD, and help reframe the way you see your brain.

For both children and adults with ADHD, recognizing these patterns can be an important step toward reducing frustration and self-criticism. When people begin to understand that their brain may simply need different strategies, structures, and supports.

With the right tools, guidance, and support, individuals with ADHD can learn practical strategies that help them work with their brain rather than against it. Over time, this can lead to greater confidence, less overwhelm, and a better understanding of how to navigate executive functioning challenges in everyday life.

If you or your child are experiencing difficulties related to ADHD or executive functioning, working with a therapist can help identify supportive strategies and build skills that make daily tasks feel more manageable.
