Re-examining sleep׳s effect on motor skills: How to access performance on the finger tapping task?
Publication date: Available online 10 February 2015 Source:Sleep Science Author(s): Sofia Isabel Ribeiro Pereira , Felipe Beijamini , Roberta Almeida Vincenzi , Fernando Mazzilli Louzada Here our goal was to determine the magnitude of sleep-related motor skill enhancement. Performance on the finger tapping task (FTT) was evaluated after a 90min daytime nap (n=15) or after quiet wakefulness (n=15). By introducing a slight modification in the formula used to calculate the offline gains we were able to refine the estimated magnitude of sleep׳s effect on motor skills. The raw value of improvement after a nap decreased...

The relationship between self-reported sleep quality and reading comprehension skills
Publication date: Available online 24 December 2014 Source:Sleep Science Author(s): Stephanie K. Ellis , Jeffrey J. Walczyk , Walter Buboltz , Victoria Felix Inadequate sleep undermines many cognitive functions, including memory, concentration, and attention, which are vital in everyday activities. We hypothesized that poor quality or shorter sleep length may impair reading-related skills, resources, and outcomes, specifically verbal working memory span, verbal efficiency, and reading comprehension. Contrary to the hypotheses, neither short sleep length nor self-reported sleep quality were related to reading skills...

Model of oronasal rehabilitation in children with obstructive sleep apnea syndrome undergoing rapid maxillary expansion: Research review
Publication date: Available online 17 November 2014 Source:Sleep Science Author(s): Luca Levrini , Paola Lorusso , Alberto Caprioglio , Augusta Magnani , Giovana Diaféria , Lia Bittencourt , Silvana Bommarito Rapid maxillary expansion (RME) is a widely used practice in orthodontics. Scientific evidence shows that RME can be helpful in modifying the breathing pattern in mouth-breathing patients. In order to promote the restoration of physiological breathing we have developed a rehabilitation program associated with RME in children. The aim of the study was a literature review and a model of orofacial rehabilitat...

Environmental noise and sleep disturbances: A threat to health?
Publication date: Available online 15 November 2014 Source:Sleep Science Author(s): Halperin Demian Environmental noise, especially that caused by transportation means, is viewed as a significant cause of sleep disturbances. Poor sleep causes endocrine and metabolic measurable perturbations and is associated with a number of cardiometabolic, psychiatric and social negative outcomes both in adults and children. Nocturnal environmental noise also provokes measurable biological changes in the form of a stress response, and clearly affects sleep architecture, as well as subjective sleep quality. These sleep perturbations ...

The effects of sleep loss on capacity and effort
Publication date: Available online 15 November 2014 Source:Sleep Science Author(s): Mindy Engle-Friedman Sleep loss appears to affect the capacity for performance and access to energetic resources. This paper reviews research examining the physical substrates referred to as resource capacity, the role of sleep in protecting that capacity and the reaction of the system as it attempts to respond with effort to overcome the limitations on capacity caused by sleep loss. Effort is the extent to which an organism will exert itself beyond basic levels of functioning or attempt alternative strategies to maintain performance. ...

The effects of long-term dopaminergic treatment on locomotor behavior in rats
This study suggests changes in locomotor activity in rats after long-term PPX treatment that include an immediate reduction of locomotion and an increase in immobilization, and after 64 days, these values returned to baseline levels without evidence of augmentation. In addition, it was not possible to demonstrate a relationship between locomotor activity and the expression of D2 receptors under these conditions. (Source: Sleep Science)

Prevalence of periodical leg movements in patients with narcolepsy in an outpatient facility in São Paulo
The objective of this study was that of describing and discussing the prevalence of periodical leg movements in patients with narcolepsy in the outpatient facility of diurnal excessive sleepiness of the Federal University of São Paulo, Brazil. We revised 59 files of patients with the clinical and electrophysiological diagnosis of narcolepsy according to the American Academy of Sleep Medicine. Of these 59 cases of patients with narcolepsy, 12 (20.3%) demonstrated periodical leg movements. Thirty five patients (59.3%) had history of cataplexy and 38 patients (64.4%) had the presence of the allele HLA-DQB1⁎0602. There was ...

Experience with the use of modafinil in the treatment of narcolepsy in a outpatient facility specialized in diurnal excessive sleepiness in São Paulo
In this study, modafinil was effective for the control of the symptoms related do narcolepsy in 66% of the studied patients. The side effects such as headache, parestesias and diarrhea were the main reasons for the discontinuation of treatment with modafinil. It is important to clinically follow up the patients for a long period to evaluate symptomatology, control of use, tolerability and re-evaluation of the more effective therapeutic dosage able to control narcolepsy. Due to its high cost and clinical benefits, this drug should be on the government׳s list of free drugs for the treatment of these patients. (Source: Sleep Science)
