We measured the effects of slow-release caffeine (SRC) and melatonin (Mlt) on sleep and daytime sleepiness after a seven-time zone eastbound flight. In a double-blind, randomized, placebo-controlled study, each of three groups of nine subjects was given either 300 mg SRC on recovery day 1 (D1) to D5 (0800) or 5 mg Mlt on preflight D-1 (1700), flight day D0 (1600), and from D1 to D3 (2300), or p...

BACKGROUND Nearly 70% of individuals with multiple sclerosis (MS) experience sleep disturbances. Increasing physical activity in people with MS has been shown to produce a moderate improvement in sleep quality, and exercise has been shown to improve sleep quality in non-neurologically impaired adults. OBJECTIVE The purpose of this pilot randomized controlled trial study was to examine the eff...

The symptom burden resulting from sleep-disordered breathing (SDB) in patients with mild-to-moderate congestive heart failure (CHF) is unclear. The current authors monitored 24-h activity levels and compared subjective and objective measures of daytime sleepiness in 39 CHF patients, New York Heart Association class 2-3, on optimal medication. A total of 22 patients were classified as SDB (apnoe...

Objectives: Sleep is a physiological process essential to life. The aim of this study is to investigate the association between demographic factors, sleep habits, and behavior in Taiwanese preschool children. Methods: This is a cross-sectional study conducted between February 2012 to April 2012. Children aged 3 to 6 years (mean age=4.59 years; 50.83% girls) were recruited from certified public ...

BACKGROUND macronutrient intake has been found to affect sleep parameters including obstructive sleep apnoea (OSA) in experimental studies, but there is uncertainty at the population level in adults. METHODS cross-sectional analysis was conducted of participants in the Men Androgen Inflammation Lifestyle Environment and Stress cohort (n = 784, age 35-80 years). Dietary intake was measured by ...

Fatigue is a frequent and distressing symptom in patients with multiple sclerosis (MS). In contrast, sleepiness, characterized by difficulties to stay awake and alert during the day, seems to be less prevalent in MS; however, exact studies are lacking. In addition, there is a semantic confusion of the concepts of "fatigue" and "sleepiness", which are often used interchangeably. We conducted a s...

The daytime polysomnogram was used to evaluate 310 consecutive patients with suspected sleep disorders, referred mainly because of excessive daytime sleepiness. Abnormalities consistent with pathologic sleep apnoea were present in 102 cases, and with narcolepsy-cataplexy in 49 cases. The daytime polysomnogram is a readily accessible, accurate, and cost-effective method for diagnosing many sleep...
