T1  - Association between pubertal stage at first drink and neural reward processing in early adulthood
JF  - Addiction biology
N2  - Puberty is a critical time period during human development. 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.

T1  - Role of CNR1 polymorphisms in moderating the effects of psychosocial adversity on impulsivity in adolescents
JF  - Journal of neural transmission
N2  - Enhanced endocannabinoid signaling has been implicated in typically adolescent behavioral features such as increased risk-taking, impulsivity and novelty seeking. Research investigating the impact of genetic variants in the cannabinoid receptor 1 gene (CNR1) and of early rearing conditions has demonstrated that both factors contribute to the prediction of impulsivity-related phenotypes. The present study aimed to test the hypothesis of an interaction of the two most studied CNR1 polymorphisms rs806379 and rs1049353 with early psychosocial adversity in terms of affecting impulsivity in 15-year-olds from an epidemiological cohort sample followed since birth. In 323 adolescents (170 girls, 153 boys), problems of impulse control and novelty seeking were assessed using parent-report and self-report, respectively. Exposure to early psychosocial adversity was determined in a parent interview conducted at the age of 3 months. The results indicated that impulsivity increased following exposure to early psychosocial adversity, with this increase being dependent on CNR1 genotype. In contrast, while individuals exposed to early adversity scored higher on novelty seeking, no significant impact of genotype or the interaction thereof was detected. This is the first evidence to suggest that the interaction of CNR1 gene variants with the experience of early life adversity may play a role in determining adolescent impulsive behavior. However, given that the reported findings are obtained in a high-risk community sample, results are restricted in terms of interpretation and generalization. Future research is needed to replicate these findings and to identify the mediating mechanisms underlying this effect.

T1  - Interaction between prenatal stress and dopamine D4 receptor genotype in predicting aggression and cortisol levels in young adults
JF  - Psychopharmacology
N2  - Considerable evidence suggests that genetic factors combine with environmental influences to impact on the development of aggressive behavior. A genetic variant that has repeatedly been reported to render individuals more sensitive to the presence of adverse experiences, including stress exposure during fetal life, is the seven-repeat allele of the dopamine D4 receptor (DRD4) gene.
 The present investigation concentrated on the interplay of prenatal maternal stress and DRD4 genotype in predicting self-reported aggression in young adults. As disruption of the hypothalamic-pituitary-adrenal system has been discussed as a pathophysiological pathway to aggression, cortisol stress reactivity was additionally examined.
 As part of an epidemiological cohort study, prenatal maternal stress was assessed by maternal interview 3 months after childbirth. Between the ages of 19 and 23 years, 298 offspring (140 males, 158 females) completed the Young Adult Self-Report to measure aggressive behavior and were genotyped for the DRD4 gene. At 19 years, 219 participants additionally underwent the Trier Social Stress Test to determine cortisol reactivity.
 Extending earlier findings with respect to childhood antisocial behavior, the results revealed that, under conditions of higher prenatal maternal stress, carriers of the DRD4 seven-repeat allele displayed more aggression in adulthood (p = 0.032). Moreover, the same conditions which seemed to promote aggression were found to predict attenuated cortisol secretion (p = 0.028).
 This is the first study to indicate a long-term impact of prenatal stress exposure on the cortisol stress response depending on DRD4 genotype.

N2  - Anhand von Daten der Mannheimer Risikokinderstudie, die sich mit der langfristigen Entwicklung von Kindern mit unterschiedlichen Risikobelastungen beschäftigt, wird gezeigt, wie Schutzfaktoren aufseiten des Kindes und seines familiären Umfelds im Verlauf der Entwicklung wirksam werden und zur Entstehung von Resilienz beitragen können. Eine besondere Rolle kommt dabei positiven frühen Eltern-Kind-Beziehungen zu (sowohl Mutter- als auch Vater-Kind-Interaktionen). Daneben spielen auch Interaktionserfahrungen im Alter von zwei Jahren des Kindes eine bedeutsame Rolle; diese schützen Risikokinder davor, eine ungünstige Entwicklung zu nehmen und tragen dazu bei, dass sich Kinder, die in psychosozialen Hochrisikofamilien aufwachsen, trotz ungünstiger „Startbedingungen“ positiv entwickeln. Neben Merkmalen der sozialen Umwelt nehmen auch sprachliche, sozial-emotionale und internale Kompetenzen des Kindes im Entwicklungsverlauf eine wichtige Rolle ein. Diese Kompetenzen ermöglichen es Risikokindern auch unter widrigen Lebensumständen (psychosoziale Hochrisikofamilien, Aufwachsen in Armutsverhältnissen) erfolgreich zu bestehen. Darüber hinaus zeigt die Arbeit, dass Resilienz ein Persönlichkeitsmerkmal ist, das ab dem frühen Erwachsenenalter eine hohe Stabilität besitzt. Mit diesen Befunden verweist die Arbeit auf die große Bedeutung der Resilienz bei der Vorhersage der langfristigen Entwicklung von Risikokindern.
N2  - Resilience refers to the ability to successfully deal with stressful life circumstances and experiences and to cope with them. Based on data from the Mannheim Study of Children at Risk, which follows a sample of children at risk from birth to adulthood, the present paper provides convincing evidence demonstrating how protective factors in the child and his/her family environment operate during the course of development to contribute to the development of resilience. As shown, a major role is assigned to positive early parent–child relationships (both mother– and father–child interactions). Moreover, positive interactive experiences at the child’s age of 2 years play a significant role. These experiences consistently contribute to a positive child development in the face of adversity. In addition to characteristics of the social environment of the child, cognitive, social–emotional, and internal competencies during childhood, youth, and young adulthood play a major role in the development of resilience. These competencies enable children at risk who are growing up in psychosocial high-risk families or in poverty to successfully cope with conditions of high adversity. Moreover, the findings presented here demonstrate that resilience may be conceived as a personal characteristic that exhibits high stability since young adulthood. With these findings, the present study points to the significance of resilience in predicting the long-term outcome of children at risk.

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.

T1  - Association of norepinephrine transporter (NET, SLC6A2) genotype with ADHD-related phenotypes: Findings of a longitudinal study from birth to adolescence
JF  - Psychiatry research : the official publication of the International Society for Neuroimaging in Psychiatry
N2  - Variation in the gene encoding for the norepinephrine transporter (NET, SLC6A2) has repeatedly been linked with ADHD, although there is some inconsistency regarding the association with specific genes. 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.

T1  - Interacting effect of MAOA genotype and maternal prenatal smoking on aggressive behavior in young adulthood
JF  - Journal of neural transmission
N2  - Findings on the etiology of aggressive behavior have provided evidence for an effect both of genetic factors, such as variation in the monoamine oxidase A (MAOA) gene, and adverse environmental factors. Recent studies have supported the existence of gene × environment interactions, with early experiences playing a key role. In the present study, the effects of prenatal nicotine exposure, MAOA genotype and their interaction on aggressive behavior during young adulthood were examined. In a sample of 272 young adults (129 males, 143 females) from an epidemiological cohort study, smoking during pregnancy was measured with a standardized parent interview at the offspring’s age of 3 months. Aggressive behavior was assessed between the ages of 19 and 25 years using the Young Adult Self-Report. DNA was genotyped for the MAOA 5′ untranslated region variable number of tandem repeats polymorphism (VNTR). Results revealed a significant interaction between MAOA and smoking during pregnancy, indicating higher levels of aggressive behavior in young adults carrying the MAOA low-expressing genotype who had experienced prenatal nicotine exposure (n = 8, p = .025). In contrast, in carriers of the MAOA high-expressing genotype, maternal smoking during pregnancy had no effect on aggressive behavior during young adulthood (n = 20, p = .145). This study extends earlier findings demonstrating an interaction between MAOA genotype and prenatal nicotine exposure on aggressive behavior into young adulthood. The results point to the long-term adverse effects of smoking during pregnancy on the offspring’s mental health, possibly underlining the importance of smoking cessation during pregnancy. According to the nature of the study (particularly sample size and power), analyses are exploratory and results need to be interpreted cautiously.

T1  - Effect of prenatal exposure to tobacco smoke on inhibitory control neuroimaging results from a 25-Year prospective study
JF  - JAMA psychiatry
N2  - IMPORTANCE: There is accumulating evidence relating maternal smoking during pregnancy to attention-deficit/hyperactivity disorder (ADHD) without elucidating specific mechanisms. Research investigating the neurobiological underpinnings of this disorder has implicated deficits during response inhibition. Attempts to uncover the effect of prenatal exposure to nicotine on inhibitory control may thus be of high clinical importance.
 MAIN OUTCOMES AND MEASURES: Functional magnetic resonance imaging response, morphometric data, lifetime ADHD symptoms, and novelty seeking.
 RESULTS: Participants prenatally exposed to nicotine exhibited a weaker response in the anterior cingulate cortex (t(168) = 4.46; peak Montreal Neurological Institute [MNI] coordinates x = -2, y = 20, z = 30; familywise error [FWE]-corrected P = .003), the right inferior frontal gyrus (t(168) = 3.65; peak MNI coordinates x = 44, y = 38, z = 12; FWE-corrected P = .04), the left inferior frontal gyrus (t(168) = 4.09; peak MNI coordinates x = -38, y = 36, z = 8; FWE-corrected P = .009), and the supramarginal gyrus (t(168) = 5.03; peak MNI coordinates x = 64, y = -28, z = 22; FWE-corrected P = .02) during the processing of the NoGo compared to neutral stimuli, while presenting a decreased volume in the right inferior frontal gyrus. These findings were obtained irrespective of the adjustment of confounders, ADHD symptoms, and novelty seeking.
