Historically, the field of sleep medicine has revolved around
electrophysiological tools. However, the use of these tools as a
neurophysiological method of investigation seems to be underrepresented today,
from both international recommendations and sleep centers, in contrast to
behavioral and psychometric tools. The aim of this article is to combine a
data-driven approach and neurophysiological and sleep medicine expertise to
confirm or refute the hypothesis that neurophysiology has declined in favor of
behavioral or self-reported dimensions in sleep medicine for the investigation
of sleepiness, despite the use of electrophysiological tools. Using Natural
Language Processing methods, we analyzed the abstracts of the 18,370 articles
indexed by PubMed containing the terms ‘sleepiness’ or ‘sleepy’ in the title,
abstract, or keywords. For this purpose, we examined these abstracts using two
methods: a lexical network, enabling the identification of concepts
(neurophysiological or clinical) related to sleepiness in these articles and
their interconnections; furthermore, we analyzed the temporal evolution of these
concepts to extract historical trends. These results confirm the hypothesis that
neurophysiology has declined in favor of behavioral or self-reported dimensions
in sleep medicine for the investigation of sleepiness. In order to bring
sleepiness measurements closer to brain functioning and to reintroduce
neurophysiology into sleep medicine, we discuss two strategies: the first is
reanalyzing electrophysiological signals collected during the standard sleep
electrophysiological test; the second takes advantage of the current trend
towards dimensional models of sleepiness to situate clinical neurophysiology at
the heart of the redefinition of sleepiness.
