measurementLess than 1 percent of older adults in primary care are referred for polysomnography, though these numbers may have increased recently due to greater awareness.

claimDepressed individuals exhibit specific abnormalities detectable via polysomnography.

measurementA large population-based study of more than 1,000 adults found a U-shaped relationship between sleep duration (measured by polysomnography) and body mass index, where adults who slept 7.7 hours had the lowest BMI, and those with shorter or longer sleep durations had progressively higher BMI.

referenceThe Sleep Heart Health Study is a community-based multicenter study of more than 6,000 middle-aged and older adults that measured the apnea-hypopnea index via polysomnography and found that the likelihood of hypertension was greater at higher apnea-hypopnea index levels.

claimPolysomnography detects abnormalities in depressed individuals including shortened initial REM periods, increased REM density, and slow-wave deficits, according to Benca (2005a).

referenceMontplaisir et al. (1997) characterized the clinical, polysomnographic, and genetic features of restless legs syndrome in a study of 133 patients.

referenceThe Sleep Heart Health Study, a large, cross-sectional, community-based study using polysomnography, found that impaired glucose tolerance and insulin resistance were more prevalent in individuals with the highest apnea-hypopnea index.

claimThe diagnosis of obstructive sleep apnea requires polysomnography to detect at least five or more apneas or hypopneas per hour of sleep.

claimThe Sleep Heart Health Study determined the apnea-hypopnea index using polysomnography and adjusted for confounding factors, including hypertension, finding that the association between obstructive sleep apnea and cardiovascular disease persisted even after adjusting for hypertension.

procedureSleep apnea testing for sleep deprivation can be conducted via an overnight sleep lab study called a polysomnogram or by using an at-home sleep apnea testing device.

procedurePolysomnograms (overnight sleep lab studies) or at-home sleep apnea testing devices are used to test for sleep apnea.

procedurePolysomnography is a clinical sleep evaluation procedure that utilizes an electroencephalogram (EEG), electrooculogram, electromyogram, electrocardiogram, pulse oximetry, airflow, and respiratory effort monitoring.

claimPolysomnography is the gold standard diagnostic test for sleep-related breathing disorders, including obstructive sleep apnea, central sleep apnea, and sleep-related hypoventilation or hypoxia.

claimPolysomnography is used to evaluate nocturnal seizures, periodic limb movement disorder, narcolepsy, and REM sleep behavior disorder.

procedureSleep scientists use polysomnography (PSGs) in laboratories to measure human brain activity, eye movement, and muscle tone to determine sleep states.

procedurePolysomnography is a physiological measurement technique used to observe sleep stages by measuring electrical activity in the brain, eye movements, and muscle movements.
