Deficits in working memory – but not ADHD

The go-to diagnosis for kids who have trouble learning, focusing and following directions in school is ADHD. Even leaving aside official diagnoses, when we look at the way parents and teachers talk about these children, it doesn’t take long for ADHD to pop up as the label of choice regardless of the actual problem.

In The Learning Brain by Torkel Klingberg, the author points out that kids who have deficits in working memory may be misdiagnosed with ADHD. People with ADHD often have problems with working memory, but not everyone with working memory issues has ADHD.

What’s working memory? There’s a colorful description of it here: “your brain’s Post-it note.”

Working memory helps you retain and process incoming information, such as a set of directions with multiple steps, the thread of a conversation, unfolding stories, math problems and other academic exercises. Even if most of this information never makes it to your long-term memory, you need to hold onto it for the present time to carry out different tasks successfully.

You can see why kids with working memory deficits struggle at school. And given that working memory and attention are closely intertwined, the label of ADHD hovers over these kids. It doesn’t help that when kids are struggling with schoolwork and falling behind their classmates, they often get restless, act out, or let their attention wander – which further reinforces the notion in people’s minds that they have ADHD.

And in kids with both ADHD and working memory deficits, the concern is that people will focus on controlling (medicating) any hyperactivity, at the expense of addressing the working memory problems.
