New research may change how we explain attention difficulties in ADHD. A study published in the Journal of Neuroscience found that adults with ADHD experience more “sleep-like slow waves” during wakefulness than neurotypical adults.

These are brief moments where small regions of the brain show activity patterns similar to sleep, even while someone is awake and trying to focus.

The researchers compared 32 adults with ADHD (off medication) with 31 neurotypical adults and found higher slow-wave activity in the ADHD group; more attention lapses, slower reaction times, and increased errors; and evidence suggesting these brain-state changes may help explain some attentional difficulties.

This doesn’t mean the ADHD brain is “falling asleep.” But it does suggest that attention challenges may be linked to measurable neurological processes, not simply motivation, discipline or effort.

For clinicians, coaches, and anyone working with ADHD, this offers powerful psychoeducation. When someone says, “I’m trying, but I just can’t stay focused,” there may be a biological explanation behind that experience.

The connection between sleep regulation and attention is becoming harder to ignore. Research like this helps shift the conversation from blame to understanding.
