Little work has been conducted that examines the effects of positive environmental experiences on brain development to date. The aim this study was prospectively investigate (warm and supportive) maternal behavior structural during adolescence, using longitudinal MRI. Participants were 188 (92 female) adolescents, who part a adolescent involved mother–adolescent interactions MRI scans at approximately 12 years old, follow-up 4 later. FreeSurfer software used estimate volume limbic-striatal...
What we know about cortical development during adolescence largely stems from analyses of cross-sectional or cohort-sequential samples, with few studies investigating brain using a longitudinal design. Further, volume is product two evolutionarily and genetically distinct features the cortex - thickness surface area, have investigated these three characteristics within same sample. The current study examined maturation thickness, area adolescence, as well sex differences in development,...
Emotional inertia refers to the degree which a person's current emotional state is predicted by their prior state, reflecting how much it carries over from one moment next.Recently, in crosssectional study, we showed that high an important characteristic of emotion dynamics observed psychological maladjustment such as depression.In present examined whether prospectively predicts onset first-episode depression during adolescence.Emotional was assessed sample early adolescents (N=165) based on...
The authors sought to investigate whether the structural development of limbic, striatal, and prefrontal regions that are critically implicated in pathophysiology depression is associated with adolescent-onset depression.In a longitudinal design, risk enriched community sample 86 adolescents (41 them female) who had no history depressive disorders participated neuroimaging assessments conducted during early (age 12) midadolescence 16). Onset was assessed for period spanning late adolescence...
The negative effects of socioeconomic disadvantage on lifelong functioning are pronounced, with some evidence suggesting that these mediated by changes in brain development. To our knowledge, no research has investigated whether parenting might buffer effects.To establish positive behaviors moderate the development and adaptive adolescents.In this longitudinal study adolescents from schools Melbourne, Australia, data were collected at 3 assessments between 2004 2012. Data analyzed August...
<h3>Context</h3> Although drug cues reliably activate the brain's reward system, studies rarely examine how processing of stimuli compares with natural reinforcers or relates to clinical outcomes. <h3>Objectives</h3> To determine hedonic responses and in long-term heroin users utility these predicting future use. <h3>Design</h3> Prospective design examining experiential, expressive, reflex modulation, cortical/attentional opiate-related affective stimuli. The opiate-dependent group was...
Abstract Early to mid‐adolescence is an important developmental period for subcortical brain maturation, but longitudinal studies of these neurodevelopmental changes are lacking. The present study acquired repeated magnetic resonance images from 60 adolescent subjects (28 female) at ages 12.5 and 16.5 years map in structure volumes. Automated segmentation techniques optimized measurement were used delineate volumes the caudate, putamen, nucleus accumbens, pallidum, hippocampus, thalamus...
Limited attention has been directed toward the influence of non-abusive parenting behaviour on brain structure in adolescents. It suggested that environmental influences during this period are likely to impact way develops over time. The aim study was investigate association between aggressive and positive behaviors development from early late adolescence, turn, psychological academic functioning using a multi-wave longitudinal design. Three hundred sixty seven magnetic resonance imaging...
Background. The amygdala and subgenual anterior cingulate cortex (sACC) are key brain regions for the generation of negative affect. In this longitudinal fMRI study adolescents we investigated how amygdala–sACC connectivity was correlated with affectivity (NA) both cross-sectionally longitudinally, examined its relationship to onset first-episode depression. Method. Fifty-six who were part a larger adolescent development included. They had no history mental illness at time their baseline...
Sleep problems are a major risk factor for the emergence of mental health in adolescence. The aim this study was to investigate post intervention effects cognitive-behavioral/mindfulness-based group sleep on and among at-risk adolescents.A randomized controlled trial (RCT) conducted across High schools Melbourne, Australia. One hundred forty-four adolescents (aged 12-17 years) with high levels anxiety sleeping difficulties, but without past or current depressive disorder, were into either...
This study examined the relation between mothers' positive and negative interaction behaviors during mother–child interactions emotion regulation (ER) depressive symptoms of their adolescent offspring. Event-planning (EPI) problem-solving (PSI) were observed in 163 mother–adolescent dyads, adolescents also provided a self-report ER responses symptoms. Sequential analyses tasks indicated that with more likely to reciprocate affective behaviors. Adolescents whose mothers displayed less...
Adolescence is a crucial period for the development of adaptive emotion regulation strategies. Despite fact that structural maturation prefrontal cortex during adolescence often assumed to underlie strategies, no longitudinal studies have directly assessed this relationship. This study examined whether use cognitive reappraisal strategies late was predicted by (i) absolute cortical thickness early and (ii) between mid-adolescence. Ninety-two adolescents underwent baseline follow-up magnetic...
It has been suggested that biological factors confer increased sensitivity to environmental influences on depressive symptoms during adolescence, a crucial time for the onset of disorders. Given critical role hippocampus in stress and processing contextual aspects environment, investigation its determining context seems warranted. This study prospectively examined hippocampal volume as measure influence aggressive maternal behavior change from early midadolescence. The interaction between...
In this study, we investigated the prospective relationship between maternal behaviors observed during mother-adolescent interactions and onset of major depressive disorder (MDD) early late adolescence (ages 12–18). Maternal expressions emotion responses to their child’s were both examined. Results demonstrated that higher rates aggressive behavior lower positive prospectively predicted MDD across adolescence. addition, negative (i.e., dysphoric) adolescents’ onset. dysphoric way mothers...
Abstract This study examined the relations among temperament, emotion regulation, and depressive symptoms in early adolescents. Early adolescents provided self-reports of temperament on two occasions, as well reports regulation symptomatology. Furthermore, 163 these participated event-planning problem-solving interactions with their mothers. Adolescents temperaments that were high negative emotionality or low effortful control displayed more emotionally dysregulated behaviors during...
