Background Despite the increasing interest in cardiac autonomic nervous activity, normal development is not fully understood. The main aim was to determine maturation of different sympathetic‐(SNS) and parasympathetic system (PNS) activity parameters healthy patients aged 0.5 20 years. A second potential sex differences. Methods Results Five studies covering 0.5‐ 20‐year age range provided impedance‐ electrocardiography recordings from which heart rate, PNS‐parameters (eg, respiratory sinus...

Background Conduct disorder (CD) rarely occurs alone but is typically accompanied by comorbid psychiatric disorders, which complicates the clinical presentation and treatment of affected youths. The aim this study was to investigate sex differences in comorbidity pattern CD systematically explore ‘gender paradox’ ‘delayed‐onset pathway’ hypotheses female CD. Methods As part FemNAT‐CD multisite study, semistructured interviews rating scales were used perform a comprehensive phenotypic...

Depression in adults is associated with risk factors for cardiovascular disease (CVD). It unclear, however, when the association between clinical depression and cardiac develops or how early life this can be detected.In an ongoing study of pediatric depression, we compared CVD including smoking, obesity, physical activity level, sedentary behavior, parental history across three samples adolescents: probands established histories childhood-onset major depressive disorder (n = 210),...

Abstract Theoretical and empirical accounts suggest that adolescence is associated with heightened reward learning impulsivity. Experimental tasks computational models can dissociate from the tendency to initiate actions impulsively (action initiation bias) are thus critical characterise mechanisms drive developmental differences. However, existing work has rarely quantified both ability action initiation, or it relied on small samples. Here, using modelling of a task collected large sample...

Background/Objectives: Ghrelin and growth hormone-releasing peptide 6 (GHRP-6) are peptides which can stimulate GH release, acting through the same receptor. its receptor have been involved in reward sensation addiction induced by natural artificial drugs, including nicotine. The present study aimed to investigate impacts of ghrelin GHRP-6 on horizontal vertical activity rats exposed chronic nicotine treatment followed acute withdrawal. Methods: Male female Wistar were daily intraperitoneal...

Theoretical and empirical accounts of conduct disorder (CD) suggest problems with reinforcement learning as well heightened impulsivity. These two facets can manifest in similar behaviour, such risk-taking. Computational models that dissociate from impulsively initiating actions are essential for understanding the cognitive mechanisms underlying CD. A large, international sample youths 11 European countries (N = 1418, typically developing (TD) n 742, CD 676) completed a task. We used...

Depressive disorders that onset in the juvenile years have been linked to far-reaching adverse consequences, making it imperative elucidate key mechanisms and contributory factors. Excessive use of regulatory responses exacerbate sadness (maladaptive mood repair) or insufficient reduce (adaptive may reflect behavioral depression risk. Cardiac vagal control, indexed by patterns respiratory sinus arrhythmia (RSA), has received attention as a putative physiological risk factor for depression....

Exposure to community violence through witnessing or being directly victimized has been associated with conduct problems in a range of studies. However, the relationship between exposure (CVE) and never studied separately healthy individuals disorder (CD). Therefore, it is not clear whether association CVE due confounding factors, because those high also tend live more violent neighborhoods, i.e. an ecological fallacy. Hence, aim present study was: (1) investigate recent current holds true...

Abstract Less is known about the relationship between conduct disorder (CD), callous–unemotional (CU) traits, and positive negative parenting in youth compared to early childhood. We combined traditional univariate analyses with a novel machine learning classifier (Angle-based Generalized Matrix Learning Vector Quantization) classify ( N = 756; 9–18 years) into typically developing (TD) or CD groups without elevated CU traits (CD/HCU, CD/LCU, respectively) using youth- parent-reports of...

Because depressive illness is recurrent, recurrence prevention should be a mainstay for reducing its burden on society. One way to reach this goal identify malleable risk factors. The ability attenuate sadness/dysphoria (mood repair) and parasympathetic nervous system functioning, indexed as respiratory sinus arrhythmia (RSA), are impaired during depression after it has remitted. present study therefore tested the hypothesis that these two constructs also may mirror factors recurrent major...

Background Impaired emotion regulation is increasingly recognized as a core feature of depressive disorders. Indeed, currently and previously depressed adults both report greater problems in attenuating sadness (mood repair) daily life than healthy controls. In contrast, studies various strategies to attenuate sad affect have mostly found that or controls were similarly successful at mood repair the laboratory. But few examined among depression‐prone youths effects trait characteristics on...

Objectives Impaired positive autobiographical memory ( AM ) is closely linked to emotional disorders. impairments are often found in depressed adults and may be related the difficulties such persons have regulating their dysphoric mood. By contrast, less known about disturbances among adolescents, or functional relationship of early‐onset depression.

Autonomic nervous system (ANS) functioning has long been studied in relation to antisocial behaviour, but relevant measures (heart rate, heart rate variability, pre-ejection period, respiration rate) have rarely considered together. This study investigated the relationship between these and behaviour. Using a sample of 1010 youths with (47.8%) without conduct disorder (52.2%) aged 9 18 years (659 females, 351 males, mean age = 14.2 years, SD 2.4), principal component analysis (PCA) was...

Affect regulation skills develop in the context of family environment, wherein youths are influenced by their parents', and possibly siblings', regulatory responses styles. Regulatory to sadness (mood repair) that exacerbate or prolong dysphoria (maladaptive mood may represent one way which depression is transmitted within families. We examined self-reported adaptive maladaptive repair across cognitive, social behavioural domains Hungarian 11- 19-year-old youth parents. Offspring included...
