 Zusammenfassung: Introduction: According to its guidelines, the Multiple Sleep Latency Test (MSLT) should be performed following an all-night polysomnography (PSG). However, the sleep quality and consequently the MSLT results may be affected by PSG and by the fact that a subject sleeps under unfamiliar conditions. The aim of this study was to examine whether PSG performed in a sleep laboratory has any influence on the MSLT and other measures of daytime sleepiness. Methods: Twenty healthy subjects with a mean age of 35.9 +/- 10.1 years underwent two MSLT examinations, and the 2 examination days were at least 4 weeks apart. In addition, on each occasion a monotonous vigilance task (VT) was performed and the subjects were asked to fill out the Epworth Sleepiness (ESS) and Visual Analogue Scales (VAS). In a cross-over design, a group of 10 subjects underwent a MSLT (MSLT-P) following a PSG and, on a second occasion, a MSLT (MSLT-N) was performed without a prior PSG. Vice versa, a second group of 10 subjects underwent first MSLT-N and then MSLT-P. Results: None of the MSLT parameters differed significantly between MSLT-P and MSLT-N. The other measures of daytime sleepiness (VT, ESS, VAS) also showed no evidence of significant differences between days with and without a prior PSG. Conclusions: The results of MSLT and other measures of daytime sleepiness in healthy subjects are not influenced by the fact whether or not the subjects had a PSG the night prior to MSLT.
