AI Article Synopsis
- Sleep deprivation has been explored as a technique to enhance EEG testing for epilepsy, but previous studies have produced inconsistent results regarding its diagnostic effectiveness.
- A meta-analysis examined 12 studies from the Web of Science and PubMed, focusing on the impact of factors like patient age, sleep deprivation duration, and EEG recording time on diagnostic value.
- While overall results showed no significant benefit, a trend indicated a slight diagnostic advantage after removing outliers, highlighting the need for standardized protocols in future research.
Article Abstract
Sleep deprivation has been studied as a method to induce sleep before EEG testing to improve the diagnosis of epilepsy. However, the effectiveness of sleep deprivation in diagnosing epilepsy through EEG in humans showed conflicting findings in previous studies. This meta-analysis aimed to provide statistical evidence for the diagnostic value of sleep-deprived EEG in epilepsy. A systematic search of the Web of Science and PubMed databases identified 12 relevant studies from May 1997 to the present. These studies were included to examine the diagnostic value of sleep-deprived EEG in epilepsy and its associated clinical variables, such as patient age, duration of sleep deprivation, and EEG recording duration. The results of the random effects model did not show a significant overall diagnostic effect for sleep-deprived EEG in epilepsy, but revealed high heterogeneity among the studies. Notably, this heterogeneity was not accounted for by the clinical variables analyzed. Upon excluding outliers, a trend suggesting a modest diagnostic value of sleep-deprived EEG emerged. The high heterogeneity among studies indicates the need for a standardized protocol for sleep deprivation in future studies. Overall, while sleep deprivation may have a small positive effect on EEG-based epilepsy diagnosis, further research is needed to better understand its impact and optimize its use in clinical practice.

Sleep deprivation and corneal chronobiology: reevaluating overnight corneal changes.
Sci Rep
January 2025
Department of Ophthalmology, Faculty of Medicine, University of Debrecen, Nagyerdei blvd. 98, Debrecen, 4012, Hungary.
This prospective cohort study is aimed to investigate circadian variations in corneal parameters, focusing on sleep-deprived subjects. Sixty-four healthy individuals (age range: 21-76 years) actively participated in this study, undergoing examinations at least five times within a 24-hour timeframe. The analysis encompassed keratometric parameters of the cornea's front (F) and back (B) surfaces, refractive power in flattest and steepest axes (K1, K2), astigmatism (Astig) and its axis (Axis), aspheric coefficient (Asph), corneal pachymetry values of thinnest corneal thickness (Pachy Min) and corneal thickness in the center of the pupil (Pachy Pupil), volume relative to the 3 and 10 mm corneal diagonal (Vol D3, Vol D10) and surface variance index (ISV).

Article Synopsis
- Neuroimaging studies show that sleep deprivation (SD) disrupts brain functional connectivity (FC), but traditional analysis methods have limitations that can lead to inconsistent findings.
- The current study employed a data-driven, whole brain voxel-based approach to assess 52 young adults, revealing significant changes in connectivity, particularly in the default mode network (DMN) and limbic network after SD.
- Results indicate that the right precuneus is crucial for FC disturbances linked to wakefulness, offering potential avenues for interventions against sleep deprivation effects.

Article Synopsis
- People often face cognitive challenges while sleep-deprived due to various obligations, which leads to different resilience levels among individuals.
- The study examines the relationship between resilience to sleep deprivation and EEG functional network metrics like mean node strength and stability during a baseline period of good rest.
- Results indicate that high mean node strength and stability correlate with resilience against sleep deprivation, but the same traits may contribute to vulnerability during natural sleep onset, revealing varying correlations over time.

Article Synopsis
- * In mice subjected to 48 hours of sleep deprivation, cTBS treatment was found to reduce oxidative stress and inflammation in hippocampal tissues by lowering malondialdehyde levels and increasing superoxide dismutase activities.
- * cTBS also mitigated excessive autophagy and promoted antioxidant capacity through the activation of the Nrf2 pathway, demonstrating its potential in reversing cognitive impairments caused by sleep deprivation.

Understanding the function of sleep requires studying the dynamics of brain activity across whole-night sleep and their transitions. However, current gold standard polysomnography (PSG) has limited spatial resolution to track brain activity. Additionally, previous fMRI studies were too short to capture full sleep stages and their cycling.
