Abstract and Keywords

This chapter pertains to the different assessment methods used to characterize insomnia, complement evaluation, and improve diagnosis accuracy. Physiological assessment methods, the most popular being polysomnography, are introduced as well as more refined neurophysiological techniques such as quantitative electroencephalography, neuroimaging, and event-related potentials. A table describing the most commonly used techniques of assessments presents the advantages and disadvantages of each of them. In addition, to compare results obtained from primary insomnia sufferers to those obtained with good sleepers, this chapter aims at providing a review of the most recent literature while, at times, taking into account results obtained from two different types of insomnia sufferers (psychophysiological and subjective/paradoxical). This chapter also briefly reports on the use of the different assessment methods in individuals afflicted with other sleep disorders. Finally, two tables stating influential research studies related to the neurophysiological assessment techniques (Table 21.2 : Power Spectral Analysis; Table 21.3 : Neuroimaging and Event-Related Potentials) complete the chapter.

Keywords: insomnia, assessment, subjective sleep, objective sleep, devices, polysomnography, power spectral analysis, neuroimaging, event-related potentials.
