ADHD and Working Memory
One question I ask in almost every coaching session is: “How are you going to remember this?” Because even with the best intentions, many of us with ADHD struggle with memory, specifically working memory.
This is why we lose our keys, forget what someone just said, or forget commitments we made. It is not a character flaw. It is a brain-based difference.
With understanding, self-compassion, and the right tools, we can reduce the impact of weaker working memory.
I. What Is Working Memory?
Working memory is the system that temporarily holds and processes information so we can complete tasks like learning, reasoning, and following instructions.
It is often described as a mental Post-it note that stores and processes information. The important part is this: working memory has limits. That mental Post-it note can only hold so much at one time.
II. How ADHD Impacts Working Memory
Research shows that people with ADHD often have significant working memory challenges, likely related to differences in brain activation, particularly in the prefrontal cortex and cerebellum.
In school-aged children, working memory is actually a stronger predictor of grades in math, spelling, and reading than IQ. That means bright students may be labeled as unmotivated when what they really need is better support for working memory. Over time, those negative messages can lead to disengagement.
ADHD tends to affect working memory in three main ways:
Capacity
There is only so much space on the mental Post-it note. When it fills up, we forget steps in a recipe, lose track of conversations, or blank on what we meant to say.
Processing speed
This is how quickly information gets onto the Post-it note and how fast we can process it. Many people with ADHD have slower processing speed than neurotypicals, which can make it harder to keep up in fast-moving conversations or environments.
Effort and self-talk
If we believe a task will take too much effort, it drains our energy before we even begin. That internal narrative directly impacts follow through.
III. What Can You Do About It?
Supporting working memory means working with your ADHD brain intentionally and taking time to pause. In the words of ADHD expert Edward Hallowell, “ADHD is like having a Ferrari engine for a brain with bicycle brakes. Strengthen the brakes, and you have a champion.”
1. Support Your Brain Physically
Sleep, balanced nutrition, and exercise, especially high intensity exercise, all improve working memory. Stress weakens it, so reducing stress where possible matters.
Self-compassion also matters. Harsh self-talk increases cognitive load. Supportive self-talk reduces it.
2. Work With Your Processing Style
We all have preferred ways of learning and processing information. When you align with your strengths, you reduce strain on working memory.
Auditory
Repeat instructions out loud. Ask others to restate information. Record and replay details.
Conceptual
Start with the big picture. Outline systems or break projects into clear frameworks. As a conceptual learner, I used outlines constantly as an attorney to see how evidence fit within each claim.
Kinesthetic
Move while thinking. Walk, stand, or use a fidget tool.
Visual
Write things down. Use diagrams, sticky notes, and mind maps.
Verbal
Talk it through. Ask questions. Repeat steps back.
Emotional
Create positive emotional engagement. Use music or body doubling with someone you trust.
Intuitive
Trust your pattern recognition, but pause to fact-check. I rely on intuition often, but I intentionally slow down to confirm accuracy.
Tactile
Handwrite notes. Print and highlight. Physically engage with the material.
3. Break Tasks Down
Smaller steps reduce cognitive load. If less has to fit on the mental Post-it note, overwhelm decreases and follow-through improves.
4. Use External Supports
Checklists, routines, calendars, alarms, and visual reminders act as external memory systems. I use checklists for my morning routine, evening routine, and client onboarding.
Organization also matters. When everything has a place, you do not have to rely on memory alone.
5. Reduce Distractions
Distractions quickly wipe working memory. Creating protected time without interruptions improves focus and retention.
