The aim of this study is to investigate the influence of circadian rhythm-dependent alertness on ESS performance. Purpose This scale [1] measures the subjective show that KSS has a high validity. The KSS was closely related to EEG and behavioral variables, indicating a high validity in measuring sleepiness. "Orexin has been identified as a master regulator of sleep-wake states, and these early results demonstrate that an OX2R agonist may reduce daytime sleepiness in NT1, where there is a loss of orexin," said Deborah Hartman, PhD, Global Program Lead .

Introduction Sleepiness is involved in a large part of the accidents in transportation and in other areas of industry ( Maycock, 1996 ). The Stanford Sleepiness Scale (SSS), developed by William C. Dement and colleagues in 1972, is a one-item self-report questionnaire measuring levels of sleepiness throughout the day. As search strategy, the following terms were combined with Boolean operators "OR" and/or "AND": drowsiness, disorders of excessive somnolence, excessive daytime sleepiness, day sleepiness, midday sleepiness, daytime sleepiness, adolescents, Brazil, Brazilian adolescents, and children.
