“…Participants were recruited through advertisements and the Netherlands Sleep Registry (Benjamins et al, 2013). Telephone screening and subsequent face-to-face interview were conducted to exclude potential participants: with any psychiatric or neurological illness; with a history of sleep apnea, restless leg syndrome, narcolepsy, circadian disorders or chronic sleep deprivation; who have used hypnotics in the previous 2 months.…”

More Severe Insomnia Complaints in People with Stronger Long-Range Temporal Correlations in Wake Resting-State EEG

et al. 2016

The complaints of people suffering from Insomnia Disorder (ID) concern both sleep and daytime functioning. However, little is known about wake brain temporal dynamics in people with ID. We therefore assessed possible alterations in Long-Range Temporal Correlations (LRTC) in the amplitude fluctuations of band-filtered oscillations in electroencephalography (EEG) recordings. We investigated whether LRTC differ between cases with ID and matched controls. Within both groups, we moreover investigated whether individual differences in subjective insomnia complaints are associated with LRTC. Resting-state high-density EEG (256-channel) was recorded in 52 participants with ID and 43 age- and sex-matched controls, during Eyes Open (EO) and Eyes Closed (EC). Detrended fluctuation analysis was applied to the amplitude envelope of band-filtered EEG oscillations (theta, alpha, sigma, beta-1, beta-2) to obtain the Hurst exponents (H), as measures of LRTC. Participants rated their subjective insomnia complaints using the Insomnia Severity Index (ISI). Through general linear models, we evaluated whether H, aggregated across electrodes and frequencies, differed between cases and controls, or showed within-group associations with individual differences in ISI. Additionally, we characterized the spatio-spectral profiles of group differences and associations using non-parametric statistics. H did not differ between cases with ID and controls in any of the frequency bands, neither during EO nor EC. During EO, however, within-group associations between H and ISI indicated that individuals who experienced worse sleep quality had stronger LRTC. Spatio-spectral profiles indicated that the associations held most prominently for the amplitude fluctuations of parietal theta oscillations within the ID group, and of centro-frontal beta-1 oscillations in controls. While people suffering from insomnia experience substantially worse sleep quality than controls, their brain dynamics express similar strength of LRTC. In each group, however, individuals experiencing worse sleep quality tend to have stronger LRTC during eyes open wakefulness, in a spatio-spectral range specific for each group. Taken together, the findings indicate that subjective insomnia complaints involve distinct dynamical processes in people with ID and controls. The findings are in agreement with recent reports on decreasing LRTC with sleep depth, and with the hypothesis that sleep balances brain excitability.

“…Participants were 17 people suffering from ID and 18 age-and sex-matched controls without sleep complaints (Table 1). Volunteers were recruited by advertisement, word of mouth, and the Sleep Registry [41] and were screened using a dedicated online screening form followed by a telephone interview to verify their eligibility to participate in the study. All participants provided written informed consent.…”

“…For the ID group, self-reported sleep onset latency or wake after sleep onset is greater than 30 min, and total sleep time is less than 6.5 hr, for at least 6 months and for more than 3 nights per week at the time of intake. Exclusion criteria for all participants were diagnosed ocular pathology, drug abuse, excessive alcohol consumption (>10 glasses per week), crossing one or more time zones in the month prior to the study, current use of alertness-, sleep-, and thermoregulation-altering medication, and any currently diagnosed sleep, neurological or psychiatric disorders other than ID according to the Sleep Registry implementation of the Duke Structured Interview for Diagnosing Sleep Disorders [41,42]. Prior to inclusion, volunteers were interviewed by telephone to verify the presence (in cases) or absence (in controls) of ID according to the third edition of the International Classification of Sleep Disorders [43].…”

“…Participants for the current study were recruited through advertisement and the Sleep Registry. 55 Participants were screened by telephone first, followed by face-to-face interviews. A total of 64 people including 32 suffering from ID (25 female, age range 21-67 y) and 32 controls (26 female, age range 22-70 y) contributed to the data for the present HEP assessment.…”
