Confusional arousal episodes, a milder form of Disorders of Arousal (DOA), reveal intriguing brain activity patterns. In a study involving a 12-year-old child with sleepwalking, 20 episodes were analyzed using high-density EEG. Findings showed a significant increase in slow wave activity (SWA) across theta, alpha, beta, and gamma frequencies during episodes compared to baseline sleep. Notably, connectivity analysis indicated enhanced communication between brain regions, particularly from the prefrontal cortex and temporal lobe, suggesting a unique brain state associated with night terrors and somnambulism.
