“…In a small longitudinal study of patients with bipolar disorder who were free of affective disorders at baseline, Perlman and colleagues reported that shorter sleep duration predicted increased depressive symptoms over the subsequent 6‐month follow‐up 20 . Even though sleep disturbances are possibly a trait marker of depression, the medical literature is inconsistent on the directionality of this association 56,57 . Paradoxically, among individuals with mood disorders, sleep restriction can also have an antidepressant effect, 58 underscoring the complex interaction between sleep duration and normal affect regulation.…”

Purpose To determine the association between sleep duration and depressive symptoms in a rural setting. Methods We conducted a cross-sectional study using data from Wave 3 of the Walk the Ozarks to Wellness Project including 12 rural communities in Missouri, Arkansas, and Tennessee (N = 1,204). Sleep duration was defined based on average weeknight and weekend hours per day: short (< 7), optimal (7-8), and long (> 8). The primary outcome was self-reported elevated depressive symptoms. Multivariable logistic regression was used to estimate adjusted prevalence odds ratios (aPOR) and 95% confidence intervals (95% CI). Findings Elevated depressive symptoms were common in this rural population (17%). Depressive symptoms were more prevalent among subjects with short (26.1%) and long (24%) sleep duration compared to those with optimal (11.8%) sleep duration. After adjusting for age, gender, race, education, employment status, income, and BMI, short sleep duration was associated with increased odds of elevated depressive symptoms (aPOR=2.12, 95% CI: 1.49, 3.01), compared to optimal sleep duration. Conversely, the association between long sleep duration and depressive symptoms was not statistically significant after covariate adjustment. Similar findings were observed when we excluded individuals with insomnia symptoms for analysis. Conclusions This study suggests that short sleep duration (<7 hours per night) and depressive symptoms are common among rural populations. Short sleep duration is positively associated with elevated depressive symptoms. The economic and healthcare burden of depression may be more overwhelming among rural populations, necessitating the need to target modifiable behaviors such as sleep habits to improve mental health.

“…Long-range temporal correlations in electroencephalographic oscillations have received increasing attention during the last decade. After their demonstration by Linkenkaer-Hansen et al (2001), and in parallel with studies regarding their reliability (Nikulin and Brismar 2004), distribution over the scalp (Nikulin and Brismar 2005), genetic contributions to LRTC (Linkenkaer-Hansen et al 2007), and their existence across a wide age range (Berthouze et al 2010), several studies focused on the associations between LRTC and depression (Lee et al 2007;Leistedt et al 2007;Linkenkaer-Hansen et al 2005). The results of these studies confirmed the existence of such associations, although the different methods and procedures used to calculate the scaling exponents make comparisons difficult.…”

Long range temporal correlations in EEG oscillations of subclinically depressed individuals: their association with brooding and suppression

et al. 2014

Long-range temporal correlations (LRTC) in brain oscillations have been found to be associated with depression severity in clinically depressed patients. Less is known, however, about the relationships between LRTC and proneness to engage in depression-related cognitive emotion regulation (ER) strategies which characterize both clinically and subclinically depressed (SBD) people. In this study we applied detrended fluctuation analysis to the amplitude envelope of broad band, theta band, and alpha band spontaneous EEG oscillations of a group of SBD individuals and a group of non-depressed individuals (both groups from a sample of healthy adults, N = 120), to whom brooding and thought suppression questionnaires were administered. Between-groups differences were not found for any band scaling exponents at any brain location, but linear correlations pointed out several associations between exponents at frontal, central, parietal, temporal, and occipital sites and maladaptive ER strategies. These results suggest that alterations in brain dynamics are related with the proneness that depressive individuals show to engage in brooding and thought suppression in order to cognitively regulate their emotions.

“…De plus, les tracés EEG enregistrés lors du sommeil lent léger, du sommeil lent profond et du sommeil paradoxal chez des hommes ayant eu une rémission d'un épisode dépressif ne démontrent pas de différences avec ceux des sujets sains. Les auteurs de cette étude concluent que certaines anomalies observées lors de l'épisode dépressif se résorbent suite à une rémission, alors que d'autres demeurent inchangées malgré le traitement [36]. Ainsi, dans les études futures, il sera nécessaire de spécifier si la comparaison se fait avec des sujets euthymiques en rémission ou avec des patients en état dysphorique, et de [37].…”
