Abstract
Objectives
Clinicians often depend on the results of the the multiple sleep latency test (MSLT) for diagnosing narcolepsy, but the diagnosis can be confusing when there is a co-existence of obstructive sleep apnea (OSA). This study is aimed to address the diagnostic tendency and the strategies of treatment for narcolepsy and other hypersomnia in the grey zone.
Methods
We performed a web-based survey of Korean neurologists who were interested in narcolepsy and had experience with sleep studies.
Results
The results of this survey present their concerns according to the severity of comorbid OSA in analyzing the results of the MSLT.
Conclusions
This study also might help by providing the opinions of experienced Korean neurologists for the assessment and management of excessive daytime sleepiness.
