claimAdvanced sleep phase syndrome is primarily associated with impaired social and occupational activities, as the total amount of sleep is generally not affected.
claimAdvanced sleep phase syndrome does not affect the total amount of sleep an individual gets, unless evening activities force later bedtimes.
claimDetermining the prevalence of advanced sleep phase syndrome is challenging because affected individuals typically do not perceive it as a disorder and therefore do not seek medical treatment.
claimPolymorphisms in circadian clock genes have been identified in a family with advanced sleep phase syndrome.
claimIndividuals with advanced sleep phase syndrome have circadian rhythms that are less than 24 hours.
claimFamilial cases of advanced sleep phase syndrome have been reported, and these cases segregate in a dominant mode.
claimBright light therapy in the evening has been used successfully in a limited study to reduce awakenings in individuals with advanced sleep phase syndrome.
claimIt is hypothesized that administration of low levels of melatonin in the early morning may be used to treat advanced sleep phase syndrome, though there are no published reports verifying this option.
claimIndividuals with advanced sleep phase syndrome do not experience a change in the total amount of sleep they receive, unless evening activities result in later bedtimes.
measurementIt is estimated that as many as 1 percent of middle-aged adults may suffer from advanced sleep phase syndrome.
referenceOndze B, Espa F, Ming LC, Chakkar B, Besset A, and Billiard M published a study on advanced sleep phase syndrome in the journal Reviews of Neurology in 2001.
referenceThe 2005 update of the International Classification of Sleep Disorders designated nine different circadian disorders, including delayed sleep phase type, advanced sleep phase type, nonentrained sleep-wake type, irregular sleep-wake type, shift work type, and jet lag type.
claimAdvanced sleep phase syndrome is characterized by involuntary bedtimes and awake times that occur more than 3 hours earlier than societal means.
claimAdvanced sleep phase syndrome is primarily associated with impaired social and occupational activities.
referencePalmer CR, Kripke DF, Savage HC Jr, Cindrich LA, Loving RT, and Elliott JA published a study on the efficacy of enhanced evening light for treating advanced sleep phase syndrome in Behavioral Sleep Medicine in 2003.
claimSeveral familial cases of advanced sleep phase syndrome have been reported, and these cases segregate in a dominant mode, according to research by Jones et al. (1999), Ondze et al. (2001), Reid et al. (2001), and Satoh et al. (2003).
referenceA study on the estimated prevalence of delayed and advanced sleep phase syndromes was published in the journal Sleep Research in 1995.
claimAffected individuals typically do not perceive advanced sleep phase syndrome as a disorder and therefore do not seek medical treatment, as noted by Reid and Zee (2005).
