claimIdiopathic hypersomnia without long sleep time is characterized by a complaint of excessive daytime sleepiness and a short mean sleep latency on the Multiple Sleep Latency Test (MSLT).
claimThe choice of medication for a psychiatric disorder should be influenced by the nature of the patient's sleep complaint, such as using sedating antidepressants at night for insomnia or alerting antidepressants for excessive daytime sleepiness.
claimExcessive daytime sleepiness, including sleep attacks, has been associated with the use of dopamine agonists in Parkinson’s disease patients (Paus et al., 2003).

claimResearch conducted over the past decade has overturned the belief that sleep loss has no health effects other than daytime sleepiness.
claimActivities associated with parasomnias are characterized by being potentially violent or injurious, disruptive to household members, resulting in excessive daytime sleepiness, or associated with medical, psychiatric, or neurological conditions, as noted by Mahowald and Ettinger (1990).
claimNewman et al. (2000) determined that daytime sleepiness predicts mortality and cardiovascular disease in older adults.
claimAnti-Ma-2 antibodies in cancer patients tend to cause hypothalamic lesions, which may precipitate daytime sleepiness and cataplexy, according to Rosenfeld et al. (2001).
claimDaytime sleepiness is a predictor of mortality and cardiovascular disease in older adults.
claimIdiopathic hypersomnia with prolonged sleep time is a rare disorder characterized by excessive daytime sleepiness where naps are typically unrefreshing, excessive daily sleep (typically more than 10 hours per day), and sleep drunkenness (sleep inertia).
measurementRestless legs syndrome (RLS), periodic limb movement disorder, sleep apnea, and excessive daytime sleepiness affect up to 70 percent of patients with end-stage renal disease receiving hemodialysis.
claimThe main symptom of sleep loss is excessive daytime sleepiness, with other symptoms including depressed mood and poor memory or concentration.
claimExcessive daytime sleepiness, including sleep attacks, has been associated with the use of dopamine agonists in patients with Parkinson’s disease, often requiring the use of daytime stimulants such as modafinil or amphetamine to relieve the sleepiness.
referenceProinflammatory cytokines, including interleukin-1, tumor necrosis factor-α, and interleukin-6, possess somnogenic and pyrogenic properties and are linked to postdialytic symptoms such as daytime sleepiness and sleep disturbances (Konsman et al., 2002; Raison and Miller, 2001; Capuron et al., 2002).
claimIndividuals with epilepsy are susceptible to nocturnal sleep disturbance and daytime sleepiness associated with commonly used medications.

claimSleep disturbances, including insomnia, excessive daytime sleepiness (hypersomnia), and parasomnia, are common features of psychiatric disorders and are listed as diagnostic criteria in the DSM-IV (APA, 1994).
claimExcessive daytime sleepiness is the defining symptom of sleep-disordered breathing, likely caused by sleep fragmentation from recurrent arousals.
claimA critical review of randomized controlled clinical trials concluded that CPAP therapy leads to convincing decreases in blood pressure specifically in patients with severe Obstructive Sleep Apnea (OSA), but shows a lack of benefit in patients who do not experience daytime sleepiness.
measurementA subgroup of patients below age 60 with both snoring and excessive daytime sleepiness experienced twice the risk of mortality, according to Lindberg et al. (1998).
claimIndividuals with Parkinson’s disease often experience excessive daytime sleepiness, and sleep disturbances typically increase as the disease progresses.
claimNarcolepsy and idiopathic hypersomnia are defined by a clinically significant complaint of excessive daytime sleepiness that is not explained by circadian sleep disorders, sleep-disordered breathing, sleep deprivation, or other medical conditions (AASM, 2005).
claimMany medical therapies have iatrogenic effects on sleep-wake regulatory systems, resulting in disturbed sleep, daytime sleepiness, and other related side effects.
referenceFava M identified daytime sleepiness and insomnia as correlates of depression.
claimCytokines used as biotherapy adjuncts, specifically interferon, interleukin-2, and tumor necrosis factor, are associated with side effects including daytime sleepiness, disturbed sleep, and depression.
procedureThe diagnosis of narcolepsy and idiopathic hypersomnia is primarily based on the Multiple Sleep Latency Test (MSLT), which objectively quantifies daytime sleepiness (Carskadon et al., 1986; Arand et al., 2005).
