| ABSTRACT |
|
Ten to 15% of general population suffers from excessive daytime sleepiness (EDS). EDS is observed more frequently in school-age children
or young adults than in middle-aged adults. The most common cause of EDS is “voluntary” sleep restriction causing night sleep deprivation.
Among the EDS conditions arising from central nervous system dysfunction, so-called primary disorders of somnolence, narcolepsy is the
most well known and extensively studied. Narcolepsy is characterized by chronic EDS and abnormal manifestations of rapid eye movement
sleep such as cataplexy, hypnagogic hallucination, and sleep paralysis. It is a frequently occurring but under-diagnosed condition that affects
0.02~0.18% of the general population in various countries. Idiopathic hypersomnia, the recurrent hypersomnias, and posttraumatic
hypersmonias also must be well understood to provide appropriate evaluation and management of the patient with EDS. Idiopathic
hypersomnia is frequently overdiagnosed due to a tendency to label as such all hypersomnias that do not fit the criteria of either narcolepsy
or sleep apnea syndrome. The authors reviewed the clinical features and pathogenesis of narcolepsy and other hypersomnias and described
diagnostic procedures and differential points between narcolepsy and other hypersomnias. |
