BACKGROUND Excessive daytime sleepiness is a frequent complaint in Parkinson's disease (PD); however the frequency and risk factors for objective sleepiness remain mostly unknown. We investigated both the frequency and determinants of self-reported and objective daytime sleepiness in patients with Parkinson's disease (PD) using a wide range of potential predictors. METHODS One hundred and thi...

STUDY OBJECTIVES A single subjective question may be an effective screening tool for excessive daytime sleepiness. This study sought to determine whether the following single question about sleepiness can measure subjective sleepiness comparably to the Epworth Sleepiness Scale (ESS): "Please measure your sleepiness on a typical day: (0 = none, 10 is highest)." The relationship between this ques...

Daytime sleepiness in children and adolescents has negative consequences on schoolchildren's daily life and functioning (1-3). Thus it is important to evaluate the prevalence of daytime sleepiness and to find out its predictors. The prevalence of excessive daytime sleepiness in children and adolescents has varied between 0 and 35% in epidemiological studies (4-10). An increase of daytime sleepi...

Objectives: The aims of this study were to evaluate patterns of circadian preferences and daytime sleepiness, and to examine the extent to which the consumption of stimulant beverages is associated with daytime sleepiness and evening chronotype among Peruvian college-age students. Methods: A total of 2,581 undergraduate students completed a self-administered comprehensive questionnaire that gat...

Effects of recent food ingestion on daytime sleepiness were assessed in 16 subjects (8 men and 8 women) who were each studied on two occasions, 28 days apart. On each occasion, subjects ate a high-fat low-carbohydrate (CHO) (fat/CHO energy ratio 54:41) meal and an isoenergetic low-fat high-CHO meal (fat/CHO energy ratio 7:88) 4 h apart in a counterbalanced order. Sleepiness was measured at 2-hr...

Sleepiness of drivers is a dangerous situation with hazardous consequences. Prolong and constant driving results in transient state of brain that resonates between awake and sleep. The brain signal pulses are studied to detect the state of sleepiness and alarm the driver about his condition. This paper reviews, the system for sleepiness detection using Electroencephalogram (EEG) signal.

Introduction: Sleepiness may predispose drivers to road traffic accidents. Obstructive Sleep Apnea Syndrome is the most common medical cause of sleepiness. Hence increased neck circumference (NC) and obesity are known as obstructive sleep apnea syndrome risk factors. This study was conducted to assess OSAS role in occurrence of road traffic accidents in sleeping drivers of commercial heavy veh...

BACKGROUND Attention Deficit Hyperactivity Disorder (ADHD) is a frequent neurodevelopmental disorder that increases accidental risk. Recent studies show that some patients with ADHD can also suffer from excessive daytime sleepiness but there are no data assessing the role of sleepiness in road safety in patients with ADHD. We conducted an epidemiological study to explore sleep complaints, inatt...
