The Study
Quantitative study of the sleep onset period via detrended fluctuation analysis: normal vs. narcoleptic subjects.
This study looked at how long it takes for people with narcolepsy to fall asleep compared to people without it, using brain wave patterns. It found a difference, but it didn't change anything or control for other factors — so we can't say narcolepsy makes people take longer to sleep, just that the two groups are different.
Analysis score
Maximum 44 for a cross-sectional study.
Where the score came from
Scientists measured how long it takes for people to fall asleep using brainwave patterns, comparing those with narcolepsy to healthy people.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — taking nearly 100 seconds longer to fall asleep means narcoleptics transition into sleep much more easily, even when trying to stay awake.
- 2Narcoleptic people took about 239 seconds to fall asleep, while healthy people took about 145 seconds.
