| Outline of Final Research Achievements |
The nocturnal sleep time of university students was 5.80 hours on weekdays and 7.69 hours on weekends based on sleep log, and total record time was less than 5 hours in portable electroencephalography on weekdays. In this sleep deprivation state, subjective sleepiness was alleviated when sleep time on weekends was long, but objective sleepiness (multiple sleep latency test; MSLT) fulfilled narcolepsy criteria by 24% of subjects.
For patients of daytime sleepiness, the receiver operating characteristic curve analyses appeared the optimal cutoffs for narcolepsy type 1 (NT1) were mean sleep latency less than or equal to 2.38 minutes, three or more sleep onset REM periods and mean REM latency less than or equal to 3.50 minutes. By logistic regression analysis, NT1 was associated only with the number of DQB1*06:02 alleles, although narcolepsy type 2 was associated with younger age, male sex and a difference in sleep times between weekdays and weekends.
