A study published in the Journal of Neuroscience investigates the impact of sleep-like brain activity during wakefulness on focus in adults with ADHD. Led by Elaine Pinggal from Monash University, the research involved 32 adults with ADHD who had discontinued medication and 31 neurotypical adults, all of whom completed a task requiring sustained attention.

The findings revealed that adults with ADHD exhibited more frequent episodes of sleep-like brain activity, which were associated with increased attention lapses. This phenomenon might help clarify the reasons behind attention difficulties in ADHD, including more errors during tasks, slower reaction times, and heightened feelings of sleepiness.
Pinggal noted that brief episodes of sleep-like brain activity are common, particularly during mentally challenging tasks. She likened it to tiring during a long run, necessitating a break. However, in individuals with ADHD, this activity occurs more frequently, suggesting that it may be a significant factor contributing to their attention and performance challenges.
The study also indicates potential future treatments aimed at addressing sleep-related brain activity. Prior research in neurotypical individuals has shown that auditory stimulation during sleep can enhance slow wave activity, potentially reducing sleep-like brain activity the following day. Pinggal suggests testing whether this approach could diminish daytime sleep-like brain activity in individuals with ADHD, offering new strategies for improving attention and task performance.
ADHD is a common neurodevelopmental disorder affecting both children and adults, characterized by persistent patterns of inattention, hyperactivity, and impulsivity. These symptoms can significantly impact daily life, affecting educational, occupational, and social functioning. Variances in symptoms are seen among individuals, with some primarily struggling with focus while others may display more hyperactive or impulsive behaviors.
