The present study analyses the variations of the skin resistance level (SRL) during 48 h of total sleep deprivation (TSD) and its relationship to body temperature, self-informed sleepiness in the Stanford Sleepiness Scale (SSS), and reaction time (RT). All of the variables were evaluated every 2 h except for the SSS, which was evaluated every hour. A total of 30 healthy subjects (15 men and 15 ...
BACKGROUND AND PURPOSE In stroke patients, obstructive sleep apnea (OSA) is associated with poorer functional outcomes than in those without OSA. We hypothesized that treatment of OSA by continuous positive airway pressure (CPAP) in stroke patients would enhance motor, functional, and neurocognitive recovery. METHODS This was a randomized, open label, parallel group trial with blind assessmen...
Aim. To compare the efficacy and safety of armodafinil, the R-enantiomer of modafinil, with modafinil in patients of shift work sleep disorder (SWSD). Material and Methods. This was a 12-week, randomized, comparative, double-blind, multicentric, parallel-group study in 211 patients of SWSD, receiving armodafinil (150 mg) or modafinil (200 mg) one hour prior to the night shift. Outcome Measures....
Background and purpose: Sleepiness is a major public health problem. Several reasons such as shift work, long time studying, etc, are the cause of sleepiness in medical students, which affect their academic performance .The aim of this study was to assess the level of daytime sleepiness in medical students. Materials and methods : Â descriptive study designed to evaluate the daytime sleepi...
Paying down the Sleep Debt: Realization of Benefits during Subsequent Sleep Restriction and Recovery
The study objective was to determine whether sleep extension (a) improves alertness and performance during subsequent sleep restriction and (b) mediates the rate at which alertness and performance are restored by postrestriction recovery sleep. Twenty-four healthy adult participants (ages 18-39) were randomly assigned to an Extended [10 hours time in bed (TIB)] or Habitual [mean (SD) = 7.09 (0....
Background : There are a few studies to assess nurses’ sleep quality and sleepiness in the Iranian context. This study thus was carried out to examine the prevalence of sleepiness and sleep quality among nurses in South East of Iran. Subjects and methods : The study applied a descriptive, explorative design.252 nurses randomly selected from Kerman University Hospitals during winter 2009. Us...
Objectives: Cardiovascilar disesases and sleep disorders are two major health problems common in old age. The aim of the present study was to examine the relationship between daytime sleepiness and cardiovascular indices among Iranian older adults. Methods & Materials: A cross-sectional design was used. The sample included 321 older adults who were selected from primary healthcare centers in K...
Introduction: Information on the sleepiness and sleep quality is limited for Asians. This study was conducted to determine the prevalence of sleepiness and sleep quality among the adult population in Iran. Materials and Methods: This is a descriptive and explorative design study in which 1100 participants randomly selected from the Kerman city population in South –East of Iran. Using two ques...
This study aimed to investigate the effects of sleep deprivation on postural control, subjective fatigue assessment and psychomotor performance, and to assess the efficiency of an objective posturographic test as an indicator of mental fatigue. Postural sway using static posturography (Romberg's test), subjective fatigue assessment (Stanford Sleepiness Scale) and psychomotor performance (Sternb...
Driver fatigue can be further categorized into passive and active based on the task-induced perspective, with its categorization necessary from a theoretical basis practical needs. Passive is caused by mental underload inactive task engagement, which considered more hazardous. To facilitate construction of driver monitoring system (DMS), current study aims to investigate physiological behaviora...
