The Epworth sleepiness scale (ESS) is often used clinically to screen for the manifestations of the behavioral morbidity associated to obstructive sleep apnea (OSA). The purpose of this study was to assess the sensitivity of the ESS in the identification of OSA, as defined by an elevated apnea-hypopnea index. A retrospective chart review of 268 consecutive(More)

DESIGN One diagnostic and 3 treatment polysomnograms were administered in a Latin-square design to identify the(More)
Sedation is the principal side effect of first generation H1 antihistamines, and recent studies have suggested that this side effect should limit the clinical application of these drugs. The sedative effect also underlies the use of these first-generation drugs as nonprescriptive remedies for insomnia. In both cases, the potential for tolerance to the(More)
To better gain insight into patient responses to insomnia, we take a medical anthropologically informed approach to patient beliefs and behaviors, particularly those related to self-diagnosis, management, help-seeking, and self-treatment of insomnia. We conducted 24 in-depth qualitative interviews in which participants were asked their beliefs about the(More)
The purpose of this study was to assess the effects of low ethanol doses on sleep and mood and to assess its reinforcing effects used as a hypnotic. Twenty healthy adults, aged 21–45 yrs, all moderate social drinkers, were studied: eleven subjects had insomnia and nine were normal sleepers, as documented by clinical polysomnography. On two sampling nights(More)

A chart review study at a sleep medicine clinic of 45 insomnia patients evaluated scores on the Dysfunctional Beliefs and Attitudes Scale(More)
OBJECTIVE The study evaluated the Time of Day Sleepiness Scale (ToDSS) to determine subjective estimates of sleepiness in the morning, afternoon, and evening. Scores on the ToDSS were compared to the Epworth Sleepiness Scale (ESS). The ToDSS was evaluated on three cohorts of patients at a sleep medicine clinic. METHOD The items of the ToDSS are modified(More)
Twenty-four men and women with insomnia, age 21–50 years, self administered hypnotics under a single-choice with placebo, single-choice with triazolam (0.25 mg), or forced-choice of placebo versus triazolam (0.25 mg) paradigm. Subjects received 4-sampling nights of placebo or triazolam in the single-choice conditions or 2 nights of each in the forced-choice(More)
