Research has suggested that patients with depression or bipolar disorder exhibit higher methylation levels in the glucocorticoid receptor gene NR3C1. We aimed to investigate whether NR3C1 methylation changes are similarly associated with externalizing disorders such as aggressive behavior and conduct disorder. NR3C1 exon 1F methylation was analyzed in young adults with a lifetime diagnosis of an externalizing disorder (N = 68) or a depressive disorder (N = 27) and healthy controls (N = 124) from the Mannheim Study of Children at Risk. The externalizing disorders group had significantly lower NR3C1 methylation levels than the lifetime depressive disorder group (p = 0.009) and healthy controls (p = 0.001) This report of lower methylation levels in NR3C1 in externalizing disorders may indicate a mechanism through which the differential development of externalizing disorders as opposed to depressive disorders might occur.

It is characterized by high levels of risk-taking behavior, such as increased alcohol consumption, and is accompanied by various neurobiological changes. Recent studies in animals and humans have revealed that the pubertal stage at first drink (PSFD) significantly impacts drinking behavior in adulthood. Moreover, neuronal alterations of the dopaminergic reward system have been associated with alcohol abuse or addiction. This study aimed to clarify the impact of PSFD on neuronal characteristics of reward processing linked to alcohol-related problems. One hundred sixty-eight healthy young adults from a prospective study covering 25 years participated in a monetary incentive delay task measured with simultaneous EEG-fMRI. PSFD was determined according to the age at menarche or Tanner stage of pubertal development, respectively. Alcohol-related problems in early adulthood were assessed with the Alcohol Use Disorder Identification Test (AUDIT). During reward anticipation, decreased fMRI activation of the frontal cortex and increased preparatory EEG activity (contingent negative variation) occurred with pubertal compared to postpubertal first alcohol intake. Moreover, alcohol-related problems during early adulthood were increased in pubertal compared to postpubertal beginners, which was mediated by neuronal activation of the right medial frontal gyrus. At reward delivery, increased fMRI activation of the left caudate and higher feedback-related EEG negativity were detected in pubertal compared to postpubertal beginners. Together with animal findings, these results implicate PSFD as a potential modulator of psychopathology, involving altered reward anticipation. Both PSFD timing and reward processing might thus be potential targets for early prevention and intervention.

The variants for which most consistent association has been found are the NET variants rs3785157 and rs28386840. Here, we tested for their association with ADHD diagnosis and ADHD-related phenotypes during development in a longitudinal German community sample. Children were followed from age 4 to age 15, using diagnostic interviews to assess ADHD. Between the ages of 8 and 15 years, the Child Behavior Checklist (CBCL) was administered to the primary caregivers. The continuous performance task (CPT) was performed at age 15. Controlling for possible confounders, we found that homozygous carriers of the major A allele of the functional promoter variant rs28386840 displayed a higher rate of ADHD lifetime diagnosis. Moreover, homozygous carriers of the minor T allele of rs3785157 were more likely to develop ADHD and showed higher scores on the CBCL externalizing behavior scales. Additionally, we found that individuals heterozygous for rs3785157 made fewer omission errors in the CPT than homozygotes. This is the first longitudinal study to report associations between specific NET variants and ADHD-related phenotypes during the course of development. (C) 2015 Elsevier Ireland Ltd.

N2 - Postpartum depression (PPD) is a common and serious mental health problem with prevalence rates ranging from 13% to 19%, and is associated with an increased risk of adverse child development. PPD is characterized by symptoms common of depression, particularly by impairments of maternity, parenting, and mother-infant interactions. Several reviews suggest an impact on attachment, cognitive, behavioral, and health-related outcome in the offspring. However, the long-term effects of PPD regarding cognitive and mental development into adulthood and the underlying mechanisms, especially the role of maternal interactional behavior, are not yet well understood. In the Mannheim Study of Children at Risk, maternal depression was assessed when the child was 3 months and 2 years old. Development from infancy to young adulthood (25 years) was assessed at regular intervals in 28 children of postnatally depressed mothers and 107 children born to mentally healthy mothers. Cognitive outcome up to age 11 was measured using standardized instruments; in adulthood, school outcome was used approximately. Psychiatric diagnosis as well as symptom scores served as psychological outcome. At age 3 months, mothers and infants were videotaped during a nursing and a playing situation. Videotapes of the 10-min session were recorded and evaluated by trained raters (kappa > .83) using the Category System for Microanalysis of Early Mother Child Interaction (Esser, Scheven, et al., 1989). The cognitive as well as social-emotional outcome of children of mothers suffering from PPD was significantly poorer than in the children of mentally healthy mothers. The adverse effects were more pronounced during childhood. The offspring of postnatally depressed mothers who interacted in a responsive manner with their infant exhibited a better prognosis in contrast to those with mothers interacting less sensitively. This effect was observed with regard to cognitive development and symptoms of externalizing behavior at age 19 years. Regarding internalizing behavior, no impact of maternal behavior was detected. These findings emphasize the importance of high-quality early mother-child interaction in the development of children at risk. Furthermore, convincing arguments are given for very early specialized treatment of impaired mother-child interactions in mothers suffering from PPD. The PPD treatment should always comprise treatment of depression as well as treatment of the disturbed mother-child interaction.

N2 - Preterm birth is associated with adverse long-term consequences regarding cognitive development. Whereas children born very preterm represent a subgroup at special risk, so-called late preterms are also affected to a lesser degree. Effects of prematurity can be observed until adulthood. For example, decreased wealth was reported in adults born preterm, which was mediated by decreased intelligence during childhood and lower educational qualifications during young adulthood. Hence, it is highly relevant to examine whether certain factors can buffer against the adverse effects of preterm birth on cognitive development. Parenting might play an important role here. There is evidence suggesting a protective effect of sensitive parenting during childhood on later cognitive outcome in preterms. In the current study, we examined whether early responsive maternal care was associated with later intelligence and academic achievement in children born preterm versus full term. As part of an ongoing cohort study, early maternal responsiveness was assessed at the child’s age of 3 months (adjusted for gestational age) during a nursing and playing situation. At age 11 years, general intelligence (IQ) was determined in n = 351 children (101 born preterm; 168 male). Until age 25 years, educational qualification was assessed in n = 313 participants (85 born preterm; 145 male). IQ at age 11 was significantly lower in preterms compared with full-term subjects after adjusting for potential confounders like maternal educational background and early psychosocial risk. A significant interaction between preterm birth and early maternal responsiveness was detected. In preterms only, higher levels of early maternal responsiveness were significantly associated with higher child IQ. Lower IQs in children born preterm as compared with those born full term were observed in the subaverage-to-average range of maternal responsiveness. Interestingly, preterms exposed to very high levels of maternal responsiveness showed slightly higher IQs when compared with children born at term. With regard to academic achievement, neither a significant effect of preterm birth nor of early maternal responsiveness occurred after adjusting for potential confounders. The results of the current study replicate and extend earlier findings with regard to a protective effect of sensitive parenting on childhood cognitive outcome in preterms. The lacking impact of prematurity on academic achievement may be explained by the exclusion of participants with IQs outside the normal range in the current study. Interventions enhancing early responsive care in parents of preterms may be advisable. More studies on long-term outcomes of such interventions on cognitive development are encouraged.

Thus, we examined the influence of functional variants related to dopamine inactivation in the dopamine transporter (DAT1) and catechol-O-methyltransferase genes (COMT) on the time-course of motor processing in a contingent negative variation (CNV) task. Methods: 64-channel EEG recordings were obtained from 195 healthy adolescents of a community-based sample during a continuous performance task (A-X version). Early and late CNV as well as motor postimperative negative variation were assessed. Adolescents were genotyped for the COMT Val(158) Met and two DAT1 polymorphisms (variable number tandem repeats in the 3'-untranslated region and in intron 8). Results: The results revealed a significant interaction between COMT and DAT1, indicating that COMT exerted stronger effects on lateralized motor post-processing (centro-parietal motor postimperative negative variation) in homozygous carriers of a DAT1 haplotype increasing DAT1 expression. Source analysis showed that the time interval 500-1000 ms after the motor response was specifically affected in contrast to preceding movement anticipation and programming stages, which were not altered. Conclusions: Motor slow negative waves allow the genomic imaging of dopamine inactivation effects on cortical motor post-processing during response evaluation. This is the first report to point towards epistatic effects in the motor system during response evaluation, i.e. during the post-processing of an already executed movement rather than during movement programming.

Here, we examined whether maternal care may buffer familial risk for psychiatric disorders in terms of reward processing. Functional magnetic resonance imaging during a monetary incentive delay task was acquired in participants of an epidemiological cohort study followed since birth (N = 172, 25 years). Early maternal stimulation was assessed during a standardized nursing/playing setting at the age of 3 months. Parental psychiatric disorders (familial risk) during childhood and the participants’ previous psychopathology were assessed by diagnostic interview. With high familial risk, higher maternal stimulation was related to increasing activation in the caudate head, the supplementary motor area, the cingulum and the middle frontal gyrus during reward anticipation, with the opposite pattern found in individuals with no familial risk. In contrast, higher maternal stimulation was associated with decreasing caudate head activity during reward delivery and reduced levels of attention deficit hyperactivity disorder (ADHD) in the high-risk group. Decreased caudate head activity during reward anticipation and increased activity during delivery were linked to ADHD. These findings provide evidence of a long-term association of early maternal stimulation on both adult neurobiological systems of reward underlying externalizing behavior and ADHD during development.
