BACKGROUND An altered breathing pattern in sleep, over two to three weeks, reported by the parents of a child on Vagal Nerve Stimulation (VNS) therapy for refractory epilepsy, prompted a sleep study in him. His polysomnography (PSG) revealed respiratory irregularity concordant with VNS activation. Dyspnoea is a well recognised and reported side effect of the VNS. However there are only a few st...

background and objective : morningness–eveningness (me) refers to the individual differences in diurnal inclination, sleep-wake pattern for activity, and vigilance in the morning and evening. quantitative and qualitative components of sleep can be measured through its quality. this study aimed to evaluate the association of me chronotype with sleep quality and insomnia in students. materials an...

BACKGROUND Sleep pattern is an important factor in a child's mental, behavioural and physical status. To evaluate the sleep patterns of children, subjective tools such as sleep logs and questionnaires are still widely used in addition to objective methods of sleep assessment. Despite the established correlation between subjective and objective sleep variables, the characteristic features of sub...

Poor sleep accompanied by little daytime impairment suggests that enough sleep has been obtained to satisfy biologic need. Decreasing wake time in bed, not increasing sleep, becomes the primary therapeutic goal. There is insufficient experience with this method to recommend its preferred use with a type of insomnia (e.g., primary vs comorbid, midlife vs late life) or with a particular pattern o...

BACKGROUND AND PURPOSE Hypersomnia, sleep-disordered breathing and narcoleptic traits such as rapid eye movement (REM) sleep onset periods (SOREMPs) have been reported in Prader-Willi syndrome (PWS). In a group of young adult patients with genetically confirmed PWS we evaluated sleep and breathing polysomnographically, including cycling alternating pattern (CAP), and we analyzed the potential i...

In spite of tremendous advances in medical science, sleep has not been understood completely. The causes for many of parasomnias are still not evident. Even then these parasomnias are treated with different drugs, one of the major groups among them being sedative hypnotics. The use of sedative hypnotics are always associated with adverse effect, and there is many a times loss of the normal slee...

BACKGROUND Sleep problems, especially in the adolescent stage of development, may be associated with excessive daytime sleepiness, impaired neurocognitive function, and a host of others leading to suboptimal performance. OBJECTIVES To determine the pattern of sleep problems in school-going adolescents based on the bedtime problems; excessive daytime sleepiness; awakenings during the night and...

OBJECTIVE Sleep restriction has been associated with deteriorated insulin sensitivity. The effects of short sleep duration have been explored little in patients with type 1 diabetes. This study addresses the question of whether sleep curtailment affects HbA1c levels in patients with type 1 diabetes. RESEARCH DESIGN AND METHODS Seventy-nine adult patients with type 1 diabetes (median age 40 ye...

The sleep-wake cycle of students is characterized by delayed onset, partial sleep deprivation and poor sleep quality. Like other circadian rhythms, the sleep-wake cycle is influenced by endogenous and environmental factors. The aim of the present study was to determine the effects of different class starting times on the sleep-wake pattern of 27 medical students. The data were collected during ...

Continuous spike and waves during sleep is an age-related epileptic encephalopathy that presents with neurocognitive regression, seizures, and an EEG pattern of electrical status epilepticus during sleep. Patients usually present around 5 years of age with infrequent nocturnal unilateral motor seizures that progress within 1 to 2 years to a severe epileptic encephalopathy with frequent seizures...
