ADHD Brains Show Strange Sleep-Like Activity During Everyday Tasks A new study published in JNeurosci examined how brief bursts of sleep-like brain activity in awake adults affect their ability to stay focused during demanding tasks. Elaine Pinggal of Monash University and her colleagues investigated whether this unusual brain activity could help explain attention difficulties commonly seen in people with ADHD. Comparing Brain Activity in ADHD and Neurotypical Adults The research team monitored sleep-like brain activity in two groups while they completed a task that required sustained attention. The study included 32 adults with ADHD who were not taking medication and 31 neurotypical adults. Participants with ADHD showed more episodes of sleep-like brain activity during the task. These moments were linked to increased attention lapses compared with the neurotypical group. Additional analysis suggested that this brain activity may help explain the connection between ADHD and attention-related difficulties such as making mistakes during tasks, responding more slowly, and feeling sleepy. Why Sleep Like Brain Activity Happens Pinggal explains that these brief brain events are actually a normal part of how the brain responds to demanding mental work. “Sleep-like brain activity is a normal phenomenon that happens during demanding tasks. Think of going for a long run and getting tired after a while, which makes you pause to take a break. Everyone experiences these brief moments of sleep-like activity. In people with ADHD, however, this activity occurs more frequently, and our research suggests this increased sleep-like activity may be a key brain mechanism that helps explain why these individuals have more difficulty maintaining consistent attention and performance during tasks.” Source:SciTechDaily @EverythingScience
