Sleep disturbances are prevalent in patients with Alzheimer' disease (AD), being one of the most troubling symptoms during the progression of disease. However, little research has been made to determine if impaired sleep patterns appear years before AD diagnosis. This study tries to shed light on this issue by performing polysomnographic recordings in healthy elders and patients with mild cogni...

OBJECTIVE To assess the effect of passive body heating on the sleep patterns of patients with fibromyalgia. METHODS Six menopausal women diagnosed with fibromyalgia according to the criteria determined by the American College of Rheumatology were included. All women underwent passive immersion in a warm bath at a temperature of 36 ±1 °C for 15 sessions of 30 minutes each over a period of thre...

Cortical evoked response potentials (ERPs) display a rich set of waveforms that are both context and state dependent. However, the mechanisms that underlie state dependent ERP patterns are unclear. Determining those mechanisms through analysis of single trial ERP waveform signatures may provide insight into the regulation of cortical column state and the roles that sleep plays in cortical funct...

Overheating may cause terminal apnoea and cot death. Rectal temperature and breathing patterns were examined in normal infants at home during the first 6 months of life. Twenty one infants had continuous overnight rectal temperature and breathing recordings for 429 nights (mean 20.4 nights, range 7-30) spaced over the first six months of life. Periods when breathing was 'regular' were directly ...

Bedtime activities, sleep environment, and their impact on sleep/wake patterns were assessed in 509 elementary school children (6-12 years of age; 252 males and 257 females). Television viewing, playing video games, and surfing the Internet had negative impact on sleep/wake parameters. Moreover, presence of a television set or video game in the child's bedroom increased their activity before be...

Primary Objective: To determine staffdocumented sleep/wake patterns of hospitalized brain injury patients. Research Design: Cohort study. Methods and Procedures: Data on 17 patients were recorded hourly for a twoweek period by staff as to the wakefulness of patients. In addition, demographic data and FIM scores were obtained. Main Outcomes and Results: Seventeen patients experienced interrupted...

During sleep, the thalamus generates a characteristic pattern of transient, 11-15 Hz sleep spindle oscillations, which synchronize the cortex through large-scale thalamocortical loops. Spindles have been increasingly demonstrated to be critical for sleep-dependent consolidation of memory, but the specific neural mechanism for this process remains unclear. We show here that cortical spindles are...

Sleep plays a key role not only in children’s physical growth, behavior, and emotional development, but also in cognitive functioning. The present study was designed to survey the sleep characteristics and to examine the associations between sleep characteristics and child-reported sleep quality in urban school-aged children of China. A random sample of 19,299 children aged 5.08 to 11.99 years ...

background and objectives: muscle relaxing technique is an effective method in improving sleep quality. the purpose of this study was to determine the effect of muscle relaxation technique on fetal outcomes in complicated pregnancies who had sleep disorders. materials and methods: this study was performed as a clinical trial on 160 pregnant women who suffered from preeclampsia and gestational d...
