A significant confounder for the MSLT
is insufficient sleep time since many people are chronically sleep deprived (35).
W, a diagnosis of narcolepsy was unlikely due to his MSLT
Intriguingly, there is some discrepancy between cataplexy improvement and lack of amelioration regarding PSG parameters and EDS as measured by MSLT
. Subjective evaluation of EDS by naps and its objective recording through MSLT
is a further difficulty in evaluating symptom severity.
The diagnosis of narcolepsy is supported by polysomnography and later by MSLT
. A dozing-off time shorter than 15 minutes, frequently shorter than 5 minutes during the test and initiation of sleep during the REM period (achievement SOREM) are diagnostic (8).
The ESS has been shown to correlate with more cumbersome, expensive, and time-consuming tests such as the Multiple Sleep Latency Test (MSLT
) in patients with sleep apnea.
The patient was a six-year-old girl whose parents reported all four cardinal symptoms of narcolepsy--paroxysmal sleep, cataplexy, hypnagogic hallucinations, and sleep paralysis--but she was misdiagnosed as having atypical epilepsy (despite the absence of EEG evidence) and a variety of other diagnoses by several internists and neurologists at eight hospitals over a period of 10 months before the correct diagnosis was confirmed by conducting a Multiple Sleep Latency Test (MSLT
) and an overnight polysomnography (PSG).
They were assessed by two consecutive nocturnal PSG to be followed by a daytime multiple sleep latency test (MSLT
At the clinical control, the patient had no residual daytime sleepiness; then MSLT
was not performed.
Sensitivity and specificity of the multiple sleep maintenance tests, the maintenance of wakefulness tests and the Epworth sleepiness scale: failure of the MSLT
as a gold standard.
In this study, we aimed to compare polysomnography (PSGI and multiple sleep latency test (MSLT
) findings in narcolepsy and idiopathic hypersomnia patients.
Two methods used to assess the impact of sleep disorders are the Multiple Sleep Latency Test (MSLT
) and the Maintenance of Wakefulness Test (MWT).
On the fourth day objective sleepiness was assessed with the Multiple Sleep Latency Test (MSLT
), and meals were provided five times to assess diet.
