whether or not acute and chronic insomnia are part of the same phenomena is an important question, one that has yet to be empirically evaluated. in recent years, the issue of “what is acute insomnia and how should it be defined?” has been the subject of renewed interest, largely owing to the conduct of several natural history studies [10,13,14] and the publication of one theoretical review dedicated to ai [6]. that is, acute insomnia may be considered a normal part of the fight/flight response. in general, chronic insomnia has been found to occur in 6–10% of the population [26,27,28,29]. in sum, the population prevalence of chronic insomnia is around 10% while up to 30% of the population experiences new onset or acute insomnia on an annual basis.
in general, the case for hyperarousal is supported by studies of central and/or autonomic nervous systems and endocrine system activation in patients with chronic insomnia as compared to good sleepers. finally, it may be the case that hyperarousal is more characteristic of certain types (e.g., ci with objective short sleep duration phenotype [76]) or sub-types of insomnia (initial, middle, and late insomnia [66]), and, therefore, these differences should be accounted for in future research. in the case of ci, while it is logical that the precipitant for sleeplessness may be the same, it is unlikely given that fight/flight levels of hyperarousal may only be sustained for minutes to hours. all this said, a conservative reading of the behavioral models of insomnia suggest that acute hyperarousal is sufficient to precipitate acute insomnia but that chronic hyperarousal is not sufficient to serve as a perpetuating factor for chronic insomnia. more, there is no clear evidence to support that the severity and frequency of ai and ci are the same (it may be the case that ai is a brief yet more intense version of ci) and/or that the biopsychosocial concomitants of ai and ci are the same.
