A new study from Monash University shows that adults with attention-deficit/hyperactivity disorder (ADHD) experience brief periods of sleep-like brain activity during the day, especially during demanding tasks. Researchers found that these moments lead to distraction, slowed reactions and mental fatigue.
The research results provide new understanding of ADHD symptoms and brain function and attention problems as they reveal the underlying causes that make it difficult for some individuals to maintain their mental focus.
The brain goes offline for a while
The research compared people with ADHD and neurotypical people in performing tasks that require focus. People with ADHD had more “mini sleep” episodes than neurotypical people.
Short sleep interruptions may not be visible but affect performance. People with ADHD made more mistakes and felt tired. Researchers say it’s as if the brain shifts gears to handle higher levels of thinking.
Researchers claim that this offline response occurs more often in people with ADHD, but it can affect any person who experiences high-stress situations. When the brain’s processing capacity reaches its maximum limit the brain makes a mini reset.
People with ADHD show more active moments that require less effort to maintain, and this leads to difficulty maintaining focus during all activities.
The new research results will fundamentally change the current understanding and treatment methods for ADHD. Experts now view ADHD through the brain structure problems present in people with the condition, rather than considering it a pure behavioral disorder.
Researchers are testing sound-based sleep stimulation methods as a possible solution to enhancing daytime concentration abilities. The current method shows potential to reduce the subtle “shutdown” episodes that occur during these early developmental stages.
Studies show that people who struggle to maintain their focus require more effort to stay on task. The way people react to mental pressure and stress reveals how their brain works.
