Sleep pattern in epilepsy patients: a polysomnographic study

Abstract

Background: Sleep disorders and epilepsy commonly exist and affect each other. Patients with epilepsy often complain of poor sleep and on the other hand, poor sleep makes epilepsy control difficult. Objectives: We aimed at comparing the sleep disturbances in a group of patients with medically controlled epilepsy versus another group with medically refractory epilepsy, from the electrophysiological standpoint. Subjects and methods: Sixty epilepsy patients were included; half of them with controlled epilepsy were assigned as group I, and the other half with refractory epilepsy was assigned as group II. All patients had an overnight polysomnogram and sleep EEG done. We excluded any patient with abnormal general or neurological clinical examination. Results: Patients in group II, had significantly delayed sleep onset latency and REM latency. However, higher arousal index, insomnia, and periodic limb movement index were found to be significantly higher in group I. Respiratory events; as light sleep durations, were observed to be higher in Group II, in addition to apnea-hypopnea index that was significantly higher in this group. Conclusion: Epilepsy affects sleep architecture and sleep-related events. Patients with refractory epilepsy suffer from more disturbance in sleep patterns. Moreover, antiepileptic drugs can have a diverse effect on sleep architecture and quality in epileptic patients.

Structural-Dynamic Characteristics of Sleep Stages in Adults With New-Onset Epileptic Seizures

“…По современным данным, острые нарушения сна инсомнического характера возникают в ответ на стрессовое воздействие и связаны с высокой реактивностью диэнцефальных структур [19]. Также нарушения сна диагностируются у большей части взрослых с эпилепсией [20]. Влияние эпилепсии на сон в общем проявляется снижением эффективности сна, увеличением латентности, фрагментацией сна и сдвигом гипнограммы в сторону поверхностных стадий [21], в то же время данных, характеризующих особенности нарушений структуры сна у взрослых с различными типами эпилепсий и эпилептическими приступами, к настоящему времени недостаточно [22].…”

A Novel Portable Real-Time Low-Cost Sleep Apnea Monitoring System based on the Global System for Mobile Communications (GSM) Network

“…Sleep-disordered breathing in elderly population is more prevalent, and it involves a longer event than young and middle-aged groups [6]. It can also be seen with other diseases like epilepsy [7], obesity [8], and venous thromboembolism (VTE) [9] and trigger them. So, the people suffering from SA cannot feel the benefits of a restful sleep due to effects caused by a collapse (total or partial) of the upper airways of the respiratory system [10].…”

Proof of Concept of a Novel Neck-Situated Wearable PPG System for Continuous Physiological Monitoring

“…Currently, the gold-standard for epilepsy patient monitoring involves a video-based electroencephalogram (EEG) or multichannel cardiorespiratory polygraphy/polysomnography (PSG) for epilepsy [12,13]. A variety of physiological channels are sensed, which might include electroencephalography (EEG), photoplethysmography (PPG), electrocardiography (ECG), electromyography (EMG), and respiratory effort.…”

“…Despite PSG and video-based EEG systems showing their versatility in overnight diagnostic studies and/or in-clinic longterm monitoring, these systems are designed with supervised clinical use in mind. Thus, they are not ideal for long-term, ideally unsupervised, monitoring of the cardio-respiratory function of the patient [12,13]. The potential wearable technologies could offer in this context is hence becoming increasingly apparent [14][15][16][17][18].…”
