Abstract and Keywords
As straightforward as it may seem, the definition of insomnia is actually fraught with complexities. This is so much the case that there is not yet a consensus on an operational definition that includes quantitative criteria for illness severity, frequency, and chronicity. Several attempts have been made, however, to refine the definition of insomnia in terms of descriptive and diagnostic types and subtypes. The absence of a universal definition for insomnia has not precluded the advancement of theories about the underlying etiology and pathophysiology of insomnia. In the present chapter, information is provided on 1) the definition of insomnia, 2) the specification of types and subtypes, 3) the prevalence and incidence of insomnia, and 4) theoretical perspectives regarding (and corresponding data related to) the etiology and pathophysiology of insomnia.
