ADHD Brains Drift into Sleep-Like Bursts While Awake, Study Finds

Researchers found that adults with ADHD show more frequent sleep-like slow waves during wakefulness while performing attention-demanding tasks, and these bursts are linked to more errors, slower reaction times, and lapses in attention. The study compared 32 adults with ADHD off medication to 31 neurotypical controls. The findings suggest a brain mechanism behind ADHD-related attention difficulties, and future work may test whether sleep-based stimulation to boost slow waves could reduce daytime sleep-like activity and improve focus.
