Night sleep does not predict day sleep in narcolepsy. 1994

It has been suggested that the increased day sleep in narcolepsy-cataplexy is secondary to the known fragmentation and reduction of night sleep, there being no differences in 24 h sleep totals from normals. Twenty-two untreated patients underwent 24 h sleep wake recordings by ambulatory monitoring. Correlations were assessed by stepwise multiple regression between day sleep and night sleep measures. Almost no significant or near significant correlations emerged. It is concluded that day sleep in narcolepsy is based upon a different mechanism, perhaps a diurnal "subvigilance syndrome" of impaired arousal mechanisms.

D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009290	Narcolepsy	A condition characterized by recurrent episodes of daytime somnolence and lapses in consciousness (microsomnias) that may be associated with automatic behaviors and AMNESIA. CATAPLEXY; SLEEP PARALYSIS, and hypnagogic HALLUCINATIONS frequently accompany narcolepsy. The pathophysiology of this disorder includes sleep-onset rapid eye movement (REM) sleep, which normally follows stage III or IV sleep.

D011237	Predictive Value of Tests	In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
