Relationship between perceived sleep and polysomnography in older adult patients
Conclusion These results suggest that the older adult population have a good perception of their sleep. The questionnaires aimed at this population should be used as an alternative to polysomnography. (Source: Sleep Science)

Pedunculopontine arousal system physiology – Implications for insomnia
Publication date: Available online 10 July 2015 Source:Sleep Science Author(s): Edgar Garcia-Rill , Brennon Luster , Susan Mahaffey , Veronica Bisagno , Francisco J. Urbano We consider insomnia a disorder of waking rather than a disorder of sleep. This review examines the role of the reticular activating system, especially the pedunculopontine nucleus, in the symptoms of insomnia, mainly representing an overactive waking drive. We determined that high frequency activity during waking and REM sleep is controlled by two different intracellular pathways and channel types in PPN cells. We found three different PPN cel...

Effects of sleep reduction on the phonological and visuospatial components of working memory
In conclusion, five days of sleep reduction produces a decrease in the phonological and visuospatial storage components of working memory, which may interfere with processing verbal information and solving problems that require spatial analysis. (Source: Sleep Science)

Treatment of obstructive sleep apnea with mandibular advancement appliance over prostheses: A case report
This study aimed to present a possible to OSA treatment with MAD in over complete upper and partial lower dentures. The patient, a 38-year-old female with mild OSA, was treated with a MAD. The respiratory parameter, such as apnea–hypopnea index, arousal index and oxyhemoglobin saturation was improved after treatment. (Source: Sleep Science)

Pedunculopontine arousal system physiology—Implications for schizophrenia
Publication date: Available online 15 May 2015 Source:Sleep Science Author(s): Edgar Garcia-Rill , Stasia D’Onofrio , Susan Mahaffey , Veronica Bisagno , Francisco J. Urbano Schizophrenia is characterized by major sleep/wake disturbances including increased vigilance and arousal, decreased slow wave sleep, and increased REM sleep drive. Other arousal-related symptoms include sensory gating deficits as exemplified by decreased habituation of the blink reflex. There is also dysregulation of gamma band activity, suggestive of disturbances in a host of arousal-related mechanisms. This review examines the role of the...

Clinical factors associated with extreme sleep apnoea [AHI>100 events per hour] in Peruvian patients: A case-control study–A preliminary report
Conclusion Our results suggest that arterial hypertension, neck circumference, and over 10% SatO2Hb≤90% in total sleep time were associated with a higher probability of Extreme OSA. We recommend investigators to study this population of Extreme OSA looking for an early diagnosis and the identification of prognostic factors in comparison with moderate to severe levels.

Principal component analysis of the EEG spectrum can provide yes-or-no criteria for demarcation of boundaries between NREM sleep stages
Publication date: Available online 10 March 2015 Source:Sleep Science Author(s): Arcady A. Putilov Human sleep begins in stage 1 and progresses into stages 2 and 3 of Non-Rapid-Eye-Movement (NREM) sleep. These stages were defined using several arbitrarily-defined thresholds for subdivision of albeit continuous process of sleep deepening. Since recent studies indicate that stage 3 (slow wave sleep) has unique vital functions, more accurate measurement of this stage duration and continuity might be required for both research and practical purposes. However, the true neurophysiological boundary between stages 2 and 3 rem...

Beyond mean values: Quantifying intraindividual variability in pre-sleep arousal and sleep in younger and older community-dwelling adults
Publication date: Available online 11 March 2015 Source:Sleep Science Author(s): Kristy D. Shoji , Caitlan Tighe , Natalie D. Dautovich , Christina S. McCrae Intraindividual variability is an often understudied aspect of health outcomes research that may provide additional, complementary information to average values. The current paper aims to further our understanding of intraindividual variability in health research by presenting the results of a daily diary study of sleep and pre-sleep arousal. Pre-sleep arousal is often implicated in poor sleep outcomes, although the arousal–sleep association is not uniform a...

The validity of Actiwatch2 and SenseWear armband compared against polysomnography at different ambient temperature conditions
Publication date: Available online 3 March 2015 Source:Sleep Science Author(s): Mirim Shin , Paul Swan , Chin Moi Chow There were no validation studies on portable sleep devices under different ambient temperature, thus this study evaluated the validity of wrist Actiwatch2 (AW2) or SenseWear armband (SWA) against polysomnography (PSG) in different ambient temperatures. Nine healthy young participants (6 males, aged 23.3±4.1y) underwent nine nights of study at ambient temperature of 17°C, 22°C and 29°C in random order, after an adaptation night. They wore the AW2 and SWA while being monitored for PSG simultaneous...

Sleep disturbances and mild cognitive impairment: A review
Conclusions Sleep disturbance is prevalent and predictive of cognitive decline in older people and in those with neurodegenerative disorders. The sleep problems have to be identified and treat to preserve the cognition and the MCI subjects with sleep disturbances have to be follow more closely to identify the initial signs of dementia.
