Purpose Of Review: There is a known interrelationship between sleep and epilepsy. This review highlights the recent findings regarding interactions between sleep and circadian rhythms and the manifestations of epilepsy and surgical treatments for refractory epilepsy.
Recent Findings: CLOCK gene expression may be reduced within the epileptogenic focus in patients with refractory epilepsy. Interictal epileptiform discharges during NREM and especially REM sleep may lateralize to the epileptogenic hemisphere. Intracranial video EEG monitoring and EEG from implanted responsive neurostimulator devices confirm scalp video EEG findings of a nocturnal peak for interictal epileptiform discharges. Successful epilepsy surgery may improve sleep macrostructure and quality. Sleep outcomes in people with epilepsy undergoing epilepsy surgery and neurostimulator implantation may provide innovative understandings into the associations between sleep and epilepsy. These associations may then provide novel therapeutic options targeting sleep and circadian pathways to improve seizure control and improve the quality of life for patients with this debilitating disorder.

Fixed sleep schedules with an 8 h time in bed (TIB) are used to ensure participants are well-rested before laboratory studies. However, such schedules may lead to cumulative excess wakefulness in young individuals. Effects on older individuals are unknown.

Purpose: Two previously proposed modelling approaches to explain the bimodal pattern of activity and/or sleep in are based on 1) the concept of morning and evening oscillators underlying the peaks of activity in the morning and evening, respectively, and 2) the concept of two cycles of buildup and decay of sleep pressure, gated only by the circadian oscillator. Previously, we simulated 24-h alertness-sleepiness curves in humans using a model postulating the circadian modulation of the buildup and decay phases of two (wake and sleep) homeostatic processes. Here, we tested whether a similar model could be applied to simulate the bimodal 24-h rhythm of fly locomotor activity and sleep.

Chemotherapy treatment can significantly increase the survival of patients with cancer, but it also causes collateral damage in the body that can lead to treatment dose reductions and can reduce patient quality of life. One understudied side effect of chemotherapy is circadian disruption, which is associated with lasting biological and behavioral toxicities. Mechanisms of how chemotherapy alters circadian rhythms remain largely unknown, although leveraging rodent models may provide insights into causes and consequences of this disruption.

Sleep deficiency is associated with infectious disease risk. However, little is known about the individual roles of different aspects of sleep, including sleep duration, sleep quality, sleep timing (assessed by chronotype) and sleep regularity (in the form of social jet lag) in this context. Here, we examined associations of the probability of reporting a cold or other infections with self-reported sleep duration, sleep quality and chronotype in a sample of 642 adults, and with social jet lag in a subsample of 274 adults.

The intricate relationship between circadian rhythms and mood is well-established. Disturbances in circadian rhythms and sleep often precede the development of mood disorders, such as major depressive disorder (MDD), bipolar disorder (BD), and seasonal affective disorder (SAD). Two primary factors, intrinsic circadian clocks and light, drive the natural fluctuations in mood throughout the day, mirroring the patterns of sleepiness and wakefulness.
