18 March 2026 Punjab Khabarnama Bureau : A new study has revealed a surprising discovery about how the brain works in people with Attention Deficit Hyperactivity Disorder (ADHD). Researchers suggest that certain brain cells, or neurons, may briefly “nap” even while a person is fully awake, potentially affecting attention and focus.
Scientists studying brain activity found that in individuals with ADHD, some neurons appear to temporarily switch into a sleep-like state while the rest of the brain remains awake. This phenomenon could explain why people with ADHD sometimes experience sudden lapses in concentration or attention during tasks.
The research focused on the activity of neurons in areas of the brain responsible for attention, decision-making and impulse control. These regions are part of the brain’s prefrontal cortex, which plays a crucial role in maintaining focus and managing behavior.
During the study, researchers monitored brain signals while participants performed tasks requiring sustained attention. They observed brief moments when small groups of neurons seemed to behave similarly to how they would during sleep. During these micro-episodes, the affected neurons became less responsive to incoming signals.
Scientists believe this temporary “offline” state may reduce the brain’s ability to process information efficiently. When neurons involved in attention momentarily disengage, it could result in brief attention lapses, slower responses or difficulty maintaining focus.
Experts say this discovery offers a new perspective on how ADHD affects brain function. Rather than viewing attention difficulties purely as behavioral issues, the findings suggest there may be underlying biological mechanisms influencing how attention is regulated in the brain.
The idea that neurons can rest while a person is awake is not entirely new. Previous research has shown that sleep-like activity can occur in small regions of the brain even during wakefulness. However, the new findings suggest this phenomenon may occur more frequently or more intensely in people with ADHD.
Researchers believe that this “local sleep” in the brain may be linked to fatigue, overstimulation or challenges in regulating brain activity. When certain neural circuits become overworked, they may temporarily shut down to recover, similar to how the body needs rest after physical exertion.
Understanding this mechanism could help scientists develop more effective treatments for ADHD in the future. If attention lapses are partly caused by neurons entering short sleep-like states, therapies might focus on stabilizing brain activity or improving neural energy regulation.
Current treatments for ADHD often include behavioral therapy, lifestyle changes and medications that affect brain chemicals such as dopamine and norepinephrine. These treatments aim to improve focus, impulse control and executive functioning.
The new research does not replace existing treatments but may provide additional insight into why certain therapies work. By understanding how neuronal activity fluctuates in ADHD, scientists could refine treatment strategies and develop new approaches to managing the condition.
Experts also emphasize that ADHD affects individuals in different ways. Symptoms can include difficulty concentrating, impulsive behavior, restlessness and challenges with organization or time management. The condition is commonly diagnosed in childhood but can continue into adulthood.
Researchers say further studies are needed to confirm the findings and explore how widespread the phenomenon of “napping neurons” is among people with ADHD. Future research may also examine whether improving sleep quality, reducing stress or optimizing brain stimulation could help reduce these brief neural shutdowns.
The study highlights how complex the human brain is and how much scientists are still learning about attention and cognition. By uncovering the hidden patterns of brain activity, researchers hope to better understand conditions like ADHD and improve the lives of those affected.
Summary
A new study suggests that in people with ADHD, some neurons may briefly enter sleep-like states while awake, potentially causing attention lapses and offering new insight into the brain mechanisms behind the condition.
