ADHD “forgetfulness” isn’t about losing memory... It’s about working memory

When people with ADHD talk about being forgetful, it’s not that we can’t remember things at all. The issue is usually working memory. Working memory is the mental space that holds information long enough for you to use it. It helps you remember what you were just doing, follow steps, or keep track of thoughts in real time. With ADHD, that system can be inconsistent. You might know something clearly, but if you don’t act on it immediately, it can disappear from your mind. Not because it’s gone forever, but because it didn’t stay active long enough to use. That’s why things like walking into a room and forgetting why, or losing a thought mid-action, are so common. It’s not carelessness. It’s a working memory system that clears too quickly, especially when there’s distraction or mental overload. This is also why external supports help so much. Writing things down, reminders, and cues aren’t about weakness; they’re about offloading a system that gets overloaded easily. Once you understand this, ADHD “forgetfulness” starts to make more sense. It’s not missing memory. It’s a workspace that doesn’t hold information for long.
