We hypothesize that the EEG changes caused by OSA could be related to the occurrence of respiratory-related arousals, as well as thalamic inhibition in the slow oscillation generation due to increases in arousal levels aimed at recovery from respiratory events. EEG activity and irregularity information from the most severely affected children were significantly associated with polysomnographic variables, which were coherent with both micro and macro sleep disruptions. We found that as the severity of the disease increases, OSA broadly affects sleep EEG to the point that the information from the different frequency bands becomes more similar, regardless of activity or irregularity. Then, a correlation network analysis was conducted to evaluate relationships between them, six polysomnography variables (apnea–hypopnea index, respiratory arousal index, spontaneous arousal index, overnight minimum blood oxygen saturation, wake time after sleep onset, and sleep efficiency), and six cognitive scores (differential ability scales, Peabody picture vocabulary test, expressive vocabulary test, design copying, phonological processing, and tower test). First, the activity and irregularity of overnight EEG spectrum were characterized in the typical frequency bands by means of relative spectral power and spectral entropy, respectively: δ 1 (0.1–2 Hz), δ 2 (2–4 Hz), θ (4–8 Hz), α (8–13 Hz), σ (10–16 Hz), β 1 (13–19 Hz), β 2 (19–30 Hz), and γ (30–70 Hz). A two-step analysis involving 294 children (176 controls, 57% males, age range: 5–9 years) was conducted for this purpose. Here, our main objective was to characterize the overnight EEG of OSA-affected children and its putative relationships with polysomnographic measures and cognitive functions. However, its relationships with sleep electroencephalogram (EEG) have been scarcely investigated. Pediatric obstructive sleep apnea (OSA) is a prevalent disorder that disrupts sleep and is associated with neurocognitive and behavioral negative consequences, potentially hampering the development of children for years. 4Pneumology Service, Río Hortega University Hospital, Valladolid, Spain.3Department of Child Health, Child Health Research Institute, The University of Missouri School of Medicine, Columbia, MO, United States.2Centro de Investigación Biomédica en Red en Bioingeniería, Biomateriales y Nanomedicina (CIBER-BBN), Valladolid, Spain.1Biomedical Engineering Group, University of Valladolid, Valladolid, Spain.Gutiérrez-Tobal 1,2*† Javier Gomez-Pilar 1,2 Leila Kheirandish-Gozal 3 Adrián Martín-Montero 1 Jesús Poza 1,2 Daniel Álvarez 1,2,4 Félix del Campo 1,2,4 David Gozal 3*† Roberto Hornero 1,2*† HEALTH | STAT NEWS | For kids with Down syndrome, a new device offers hope for treating difficult sleep problems.Gonzalo C.

How many times have you woken up from a dream that has deeply stirred your emotions? Terrifying dreams of chasing and fighting, grandiose experiences of free flight through space, moving or disturbing reunions with loved ones who have drifted away or died. A single dream that is particularly remarkable for its beauty, surprise, power or sadness can completely change your day, your week, your life. ![]() The effect on health and lifestyle is likely to be profound. People are seeing into themselves in ways not possible before and are finding new ways to act on what they learn. An Apple Watch collects millions of data points per day.
