Titre : Reward-related decision-making in pediatric major depressive disorder: an fMRI study Type de document : Texte imprimé et/ou numérique Auteurs : Erika E. FORBES, Auteur ; Boris BIRMAHER, Auteur ; David A. AXELSON, Auteur ; J. Christopher MAY, Auteur ; Greg J. SIEGLE, Auteur ; Cecile D. LADOUCEUR, Auteur ; Neal D. RYAN, Auteur ; Cameron S. CARTER, Auteur ; Ronald E. DAHL, Auteur Année de publication : 2007 Article en page(s) : p.1031–1040 Langues : Anglais (eng) Mots-clés : Depression reward decision-making Index. décimale : PER Périodiques Résumé : Background: Although reward processing is considered an important part of affective functioning, few studies have investigated reward-related decisions or responses in young people with affective disorders. Depression is postulated to involve decreased activity in reward-related affective systems.
Methods: Using functional magnetic resonance imaging (fMRI), we examined behavioral and neural responses to reward in young people with depressive disorders using a reward decision-making task. The task involved choices about possible rewards involving varying magnitude and probability of reward. The study design allowed the separation of decision/anticipation and outcome phases of reward processing. Participants were 9–17 years old and had diagnoses of major depressive disorder (MDD), anxiety disorders, or no history of psychiatric disorder.
Results: Participants with MDD exhibited less neural response than control participants in reward-related brain areas during both phases of the task. Group differences did not appear to be a function of anxiety. Depressive and anxiety symptoms were associated with activation in reward-related brain areas.
Conclusions: Results suggest that depression involves altered reward processing and underscore the need for further investigation of relations among development, affective disorders, and reward processing.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2006.01673.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=793

Further, atypical functioning of the HPA axis has been linked to the pathogenesis of depression. The purpose of this study was to examine the role of adolescent HPA axis functioning in the link between adolescent sleep problems and later depressive symptoms. Methods: A sample of 157 17-18 year old adolescents (61.8% female) completed the Pittsburgh Sleep Quality Inventory (PSQI) and provided salivary cortisol samples throughout the day for three consecutive days. Two years later, adolescents reported their depressive symptoms via the Center for Epidemiological Studies Depression Scale (CES-D). Results: Individuals (age 17-18) with greater sleep disturbance reported greater depressive symptoms two years later (age 19-20). This association occurred through the indirect effect of sleep disturbance on the cortisol awakening response (CAR) (indirect effect = 0.14, 95%CI [.02 -.39]). Conclusions: One pathway through which sleep problems may lead to depressive symptoms is by up-regulating components of the body's physiological stress response system that can be measured through the cortisol awakening response. Behavioral interventions that target sleep disturbance in adolescents may mitigate this neurobiological pathway to depression during this high-risk developmental phase.

Titre : The impact of experimental sleep restriction on affective functioning in social and nonsocial contexts among adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Dana L. MCMAKIN, Auteur ; Ronald E. DAHL, Auteur ; Daniel J. BUYSSE, Auteur ; Jennifer C. COUSINS, Auteur ; Erika E. FORBES, Auteur ; Jennifer S. SILK, Auteur ; Greg J. SIEGLE, Auteur ; Peter L. FRANZEN, Auteur Article en page(s) : p.1027-1037 Langues : Anglais (eng) Mots-clés : Sleep sleep restriction adolescence affect emotion emotional reactivity emotion regulation pupillography social behavior Index. décimale : PER Périodiques Résumé : Background Short sleep duration is highly prevalent in adolescence, and it prospectively predicts problems with emotional adjustment and psychiatric health. To move beyond epidemiological associations and inform models of developmental psychopathology, we experimentally restricted sleep to observe impacts on affective functioning. Based on the importance of social contexts to adolescent emotional experiences, we also examined the impact of restricted sleep on socioaffective functioning in an ecologically valid peer interaction task. Methods In Study 1, adolescents (ages 11.5–15.0, n = 48) were randomly assigned to two nights of polysomnography-monitored sleep restriction (4 hr in bed) or extension (10 hr in bed). One week later, they completed the other sleep manipulation. Affective functioning was assessed by self-report and pupil response to standardized affective sounds. Study 2 used a similar protocol and invited adolescents (ages 12–15.0, n = 16) to the sleep laboratory along with 2–4 friends to observe affective behavior in a social context primed for peer conflict. Mixed effects models were used to evaluate the effect of sleep condition on affective outcomes. Results Study 1 demonstrated increased negative affect following sleep restriction, relative to extension, on self-report (p = .02) and pupil measures (p = .01). Study 2 replicated these effects (both p = .04) and demonstrated greater negative affective behavior in a peer social context (p = .01). Exploratory analyses for positive affect showed reductions as assessed by self-report (p = .005), but not pupil (p = .81), in Study 1; and no significant effects in Study 2 (self-report, p = .14; pupil, p = .29; positive affective behavior, p = .43). Conclusions Experimental sleep restriction in adolescence impacts negative affective functioning as evidenced by self-report and pupil reactivity, as well as observed behavior in a social context primed for peer conflict. Implications for the impact of short sleep on developmental trajectories of emotional adjustment and psychiatric health, and opportunities for early intervention, are briefly discussed.

GUNNAR, Auteur ; Ronald E. DAHL, Auteur ; Stephen D. BENNING, Auteur Année de publication : 2009 Article en page(s) : p.27-45 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : We examined puberty-specific effects on affect-related behavior and on the psychophysiology of defensive and appetitive motivation while controlling for age. Adolescents (N = 94, ages = 12 and 13 years) viewed 75 pictures (International Affective Picture System: pleasant, neutral, and aversive) while listening to auditory probes. Startle response and postauricular (PA) reflex were collected as measures of defensive and appetitive motivation, respectively. Pubertal status and measures of anxiety/stress reaction and sensation/thrill seeking were obtained. Mid-/late pubertal adolescents showed enhanced startle amplitude across all picture valences. A Puberty × Valence interaction revealed that mid-/late pubertal adolescents showed appetitive potentiation of the PA, whereas pre-/early pubertal adolescents showed no modulation of the PA reflex. Mid-/late pubertal adolescents also scored significantly higher on measures of sensation/thrill seeking than did their pre-/early pubertal peers and puberty moderated the association between psychophysiology and behavioral measures, suggesting that it plays a role in reorganizing defensive and appetitive motivational systems.

MCMAKIN, Auteur Article en page(s) : p.1309-1322 Langues : Anglais (eng) Mots-clés : Sleep adolescence anxiety Index. décimale : PER Périodiques Résumé : BACKGROUND: Vigilant attention to threat is commonly observed in anxiety, undergoes developmental changes in early adolescence, and has been proposed to interfere with sleep initiation and maintenance. We present one of the first studies to use objective measures to examine associations between vigilant attention to threat and difficulties initiating and maintaining sleep in an early adolescent anxious sample. We also explore the moderating role of development (age, puberty) and sex. METHODS: Participants were 66 peripubertal youth (ages 9-14) with a primary anxiety disorder and 24 healthy control subjects. A dot-probe task was used to assess attentional bias to fearful relative to neutral face stimuli. Eye-tracking indexed selective attentional bias to threat, and reaction time bias indexed action readiness to threat. Sleep was assessed via actigraphy (e.g. sleep onset delay, wake after sleep onset, etc.), parent report (Children's Sleep Habits Questionnaire), and child report (Sleep Self-Report). The Pediatric Anxiety Rating Scale assessed anxiety severity. RESULTS: Eye-tracking initial threat fixation bias (beta = .33, p = .001) and threat dwell time bias (beta = .22, p = .041) were positively associated with sleep onset latency. Reaction time bias was positively associated with wake after sleep onset (beta = .24, p = .026) and parent-reported sleep disturbance (beta = .25, p = .019). Anxiety (severity, diagnosis) was not associated with these outcomes. Sex (beta = -.32, p = .036) moderated the relation between initial threat fixation bias and sleep onset latency, with a positive association for males (p = .005), but not for females (p = .289). Age and pubertal status did not moderate effects. CONCLUSIONS: Vigilant attention to threat is related to longer sleep onset and reduced sleep maintenance. These associations are not stronger in early adolescents with anxiety. Implications for early intervention or prevention that targets vigilant attention to threat to impact sleep disturbance, and vice versa, are discussed.
