However, the long-term effects of prenatal maternal depression regarding internalizing psychopathology in the offspring are as yet unclear. Results: In n=85 young adults exposed to prenatal maternal depressed mood, no significantly higher risk for a diagnosis of depressive disorder was observed. However, they reported significantly lower levels of depressive symptoms. This association was especially pronounced when prenatal maternal depressed mood was present during the first trimester of pregnancy and when maternal mood was depressed pre- as well as postnatally. At an uncorrected level only, prenatal maternal depressed mood was associated with decreased amygdala volume. Limitations: Prenatal maternal depressed mood was not assessed during pregnancy, but shortly after childbirth. No diagnoses of maternal clinical depression during pregnancy were available. Conclusions: Self-reported depressive symptoms do not imply increased, but rather decreased symptom levels in young adults who were exposed to prenatal maternal depressed mood. A long-term perspective may be important when considering consequences of prenatal risk factors.

Moreover, homozygous carriers of the DRD4 7r allele displayed more externalizing behavior following exposure to higher levels of prenatal maternal stress, while homozygous carriers of the DRD4 4r allele turned out to be insensitive to the effects of prenatal stress. ConclusionsThis study is the first to report a gene-environment interaction related to DRD4 and prenatal maternal stress using data from a prospective study, which extends earlier findings on the impact of prenatal maternal stress with respect to childhood antisocial behavior.

Problematic cannabis use is often associated with comorbid psychopathological problems. The purpose of the current study was to elucidate the underlying developmental processes connecting externalizing and internalizing psychopathology in childhood and adolescence with problematic cannabis use in young adulthood. Methods: Data were drawn from the Mannheim Study of Children at Risk, an ongoing epidemiological cohort study from birth to adulthood. For n = 307 participants, symptom scores of conduct/oppositional defiant disorder, attention problems, hyperactivity/impulsivity, and internalizing disorders were available for the periods of childhood (4.5-11 years) and adolescence (15 years). At age 25 years, problematic cannabis use was assessed via clinical interview and a self-rating questionnaire. Results: At age 25 years, problematic cannabis use was identified in n = 28 participants (9.1%). Childhood conduct/oppositional behavior problems were predictive of problematic cannabis use during young adulthood when comorbid symptoms were controlled for. No such effect was found for childhood attention, hyperactivity/impulsivity or internalizing problems. With respect to psychopathological symptoms during adolescence, only attention problems were significantly related to later problematic cannabis use when controlling for comorbidity. Conclusions: The current study highlights the role of conduct/oppositional behavior problems during childhood and attention problems during adolescence in later problematic cannabis use. It sheds more light on the developmental sequence of childhood and adolescence psychopathology and young adult cannabis use, which is a prerequisite for effective prevention approaches.

Außerdem werden Auswirkungen der LRS auf das spätere Schriftsprachniveau und den Schulerfolg überprüft. Methodik: Eingangs wurden 995 Schüler zwischen 6 und 16 Jahren untersucht. Ein Teil dieser Kinder ist nach 43 sowie 63 Monaten nachuntersucht worden. Eine LRS wurde diagnostiziert, wenn für das Lesen bzw. Rechtschreiben das doppelte Diskrepanzkriterium von 1.5 Standardabweichungen zur nonverbalen Intelligenz und dem Mittelwert der Klassenstufe erfüllt war und gleichzeitig keine Minderbegabung vorlag. Ergebnisse: Die LRS weist über einen Zeitraum von 63 Monaten eine hohe Störungspersistenz von knapp 70 % auf. Der 5-Jahres-Verlauf der mittleren Lese- und Rechtschreibleistungen wurde nicht vom Geschlecht beeinflusst. Trotz durchschnittlicher Intelligenz blieben die LRS-Schüler in der Schriftsprache mindestens eine Standardabweichung hinter durchschnittlich und etwa 0.5 Standardabweichungseinheiten hinter unterdurchschnittlich intelligenten Kindern zurück. Der Schulerfolg der LRS-Schüler glich dem unterdurchschnittlich intelligenter Kinder und fiel deutlich schlechter aus als bei durchschnittlich intelligenten Kontrollkindern. Schlussfolgerungen: Eine LRS stellt ein erhebliches Entwicklungsrisiko dar, was frühzeitige Diagnostik- und Therapiemaßnahmen erfordert. Dafür sind reliable und im Hinblick auf die resultierenden Prävalenzraten sinnvolle, allgemein anerkannte Diagnosekriterien essenziell. N2 - Objective: The study examines the 5-year course of children with dyslexia with regard to their sex. Furthermore, the study investigates the impact of dyslexia on the performance in reading and spelling skills and school-related success. Method: A group of 995 6- to 16-year-olds were examined at the initial assessment. Part of the initial sample was then re-examined after 43 and 63 months. The diagnosis of dyslexia was based on the double discrepancy criterion using a standard deviation of 1.5. Though they had no intellectual deficits, the children showed a considerable discrepancy between their reading or writing abilities and (1) their nonverbal intelligence and (2) the mean of their grade norm. Results: Nearly 70 % of those examined had a persisting diagnosis of dyslexia over a period of 63 months. The 5-year course was not influenced by sex. Despite average intelligence, the performance in writing and spelling of children suffering from dyslexia was one standard deviation below a control group without dyslexia with average intelligence and 0.5 standard deviations below a group of children suffering from intellectual deficits. Furthermore, the school-related success of the dyslexics was significantly lower than those of children with average intelligence. Dyslexics showed similar school-related success rates to children suffering from intellectual deficits. Conclusions: Dyslexia represents a considerable developmental risk. The adverse impact of dyslexia on school-related success supports the importance of early diagnostics and intervention. It also underlines the need for reliable and general accepted diagnostic criteria. It is important to define such criteria in light of the prevalence rates.

N2 - Is a specific disorder of arithmetic skills as common as reading/spelling disorder?Background: Referring to the prevalence rates of learning disorders in the research literature, the numbers of mathematics disorder and reading/ spelling disorder are often reported to be identical. However, the correlation between intelligence level and reading/ spelling skills is much weaker than between intelligence and arithmetic skills. If the same definition criterion is applied to both disorders, a lower prevalence rate for mathematics disorder should be expected. Objective: Are there differences in the prevalence estimates for learning disorders depending on the definition criterion? Method: A large representative sample of German students (N = 1970) was used to review the hypothesis. Results: Depending on the definition criterion, we could show a prevalence range of mathematics disorder between 0.1% and 8.1% in the same sample. Using the same definition criterion for both learning disorders, there are two to three times as many students with reading/spelling disorder than those with mathematics disorder. Discussion: Whenever children with reading/spelling disorder are compared to children with mathematics disorder, the same definition criterion has to be applied.

Gemäß den klinisch- diagnostischen Leitlinien der ICD-10 (WHO 1993) spricht man von einer Enuresis, wenn es am Tag oder in der Nacht zu einem Entleeren der Blase in die Kleidung bzw. das Bett kommt, die relativ zum geistigen Entwicklungsstand der Person abnorm ist und nicht auf organische Ursachen zurückgeführt werden kann. Die Störungen der Blasenkontrolle dürfen nicht als Folge einer neurologischen Erkrankung, epileptischer Anfälle oder einer strukturellen Anomalie der ableitenden Harnwege auftreten. Gemäß den Forschungskriterien der ICD-10 (WHO 1994) muss das einnässende Kind nach seinem Lebens- und geistigen Alter mindestens 5 Jahre alt sein, um von einer nichtorganischen Enuresis (F 98.0) zu sprechen (in den klinisch-diagnostischen Leitlinien wird ein geistiger Entwicklungsstand gefordert, der mindestens dem eines Vierjährigen entspricht). Um die Diagnose zu erhalten, müssen Kinder unter 7 Jahren zumindest 2mal monatlich, 7-jährige oder ältere Kinder wenigstens einmal im Monat einnässen. Die Symptomdauer sollte mindestens 3 Monate betragen. In der Literatur wird synonym zum Begriff der "nichtorganischen Enuresis" häufig die Bezeichnung "funktionelle Enuresis" verwendet. Auch nach dem DSM-IV (Saß et al. 1996) sollten die Kinder für die Diagnose einer Enuresis (307.6) zumindest ein Entwicklungsalter von 5 Jahren aufweisen und die Symptomatik muss wenigstens seit 3 Monaten bestehen. Im Unterschied zur ICD-10 wird das Einnässen erst dann als klinisch bedeutsam beurteilt, wenn es mindestens 2mal wöchentlich auftritt. Ist dies nicht gegeben, kann die Diagnose dennoch gestellt werden, wenn durch das Einnässen klinisch bedeutsames Leiden hervorgerufen wird oder Beeintraechtigungen in sozialen, schulischen (beruflichen) oder anderen wichtigen Funktionsbereichen entstehen. Die Forderung eines 2mal wöchentlichen Einnässens erscheint deutlich zu streng, während das ein- bzw. 2malige Einnässen pro Monat ein sehr weiches Kriterium darstellt. V. Gontard (1998b) empfiehlt, Einnässen dann als klinisch bedeutsam einzuschätzen, wenn dies mindestens einmal wöchentlich auftritt.

T1 - An interaction between a neuropeptide Y gene polymorphism and early adversity modulates endocrine stress responses JF - Psychoneuroendocrinology N2 - Interindividual variability in the regulation of the human stress system accounts for a part of the individual's liability to stress-related diseases. These differences are influenced by environmental and genetic factors. Early childhood adversity is a well-studied environmental factor affecting an individual's stress response which has been shown to be modulated by gene environment interaction (GxE). Neuropeptide Y (NPY) plays a role in stress regulation and genetic variation in NPY may influence stress responses. In this study, we analyzed the association of a common variant in the NPY gene promoter, rs16147, with cortisol and ACTH responses to acute psychosocial stress in young adults from the Mannheim Study of Children at Risk (MARS), an ongoing epidemiological cohort study following the outcome of early adversity from birth into adulthood. We found evidence of a GxE interaction between rs16147 and early adversity significantly affecting HPA axis responses to acute psychosocial stress. These findings suggest that the neurobiological mechanisms linking early adverse experience and later neuroendocrine stress regulation are modulated by a gene variant whose functional relevance is documented by increasing convergent evidence from in vitro, animal and human studies.

Event-related potentials (ERPs) of 122 children aged 8 years (63 boys, 59 girls) were compared depending on father's alcoholism subtype: 30 COAs without paternal delinquency, 10 COAs with paternal delinquency, and 82 children of non-alcoholic and non-delinquent fathers. ERPs were recorded from Fz, Cz, and Pz, using an auditory oddball paradigm. Sinus tones of 60 dB HL were presented binaurally at 1,000 Hz (standard stimulus) and 2,000 Hz (target stimulus), at a relative frequency ratio of 80:20. Two trial blocks of 250 stimuli each were collected. Results indicated that only COAs with paternal delinquency displayed significant differences from the control group, characterized by reduced P300 amplitude at frontal site and in the second trial block. Thus, the combination of fathers' alcoholism and delinquency was more likely to relate to attenuated P300 amplitude in the offspring than paternal alcoholism alone. Our results suggest that both alcoholic and delinquent family history appear to play a role in P300 amplitude reduction in the offspring.

Latent Profile Analyses and Latent Transition Analyses yielded four main findings: A three-type solution provided the best fit to the data: an asymptomatic type (i.e., low problem scores in all three domains), a depressed type (i.e., high scores in depression), an aggressive type (i.e., high scores in aggression). Profile types were invariant over the two data waves but differed between girls and boys, revealing gender specific patterns of comorbidity. Stabilities over time were high for the asymptomatic type and for types that represented problems in one domain, but moderate for comorbid types. Differences in demographic variables (i.e., age, socio-economic status) and individual characteristics (i.e., self-esteem, dysfunctional cognitions, cognitive capabilities) predicted profile type memberships and longitudinal transitions between types.

Ergebnisse: Die Prävalenz von Rechenstörungen betrug 1.4 %, Rechenschwächen traten bei 11.2 % auf. Rechen-probleme zeigten eine mittlere bis hohe Persistenz. Schüler mit Rechenschwäche blieben im Rechnen gut eine Standardabweichung hinter durchschnittlich und ca. eine halbe Standardabweichung hinter unterdurchschnittlich intelligenten Kontrollkindern zurück. Der allgemeine Schulerfolg rechenschwacher Probanden (definiert über Mathematiknote, Deutschnote und Schultyp) ähnelte dem der unterdurchschnittlich intelligenten Kontrollgruppe und blieb hinter dem Schulerfolg durchschnittlich intelligenter Kontrollkinder zurück. Eingangs ältere Probanden mit Rechenproblemen (4. bis 5. Klasse) wiesen eine schlechtere Prognose auf als Kinder, die zu Beginn die 2. oder 3. Klasse besuchten.

N2 - Objective: The present study examines the 5 years course of mathematics learning disabilities (MLD) and poor mathematics achieve-ment in children from primary to secondary schools. The study investigates the persistence and the impact of mathematical difficulties on the later mathematics performance and school-related success. Method: First, 2909 second to fifth graders were examined with standardized tests in mathematical skills and intelligence. A part of these children was re-examined after 37 and after 68 months. Results: A prevalence of 1.4 % for MLD and 11.2 % for poor mathematics achievement was determined. Mathematical difficulties showed medium to high persistence. Later performance of children with poor mathematics achievement was one standard deviation below a control group without mathematical difficul-ties with average intelligence and 0.5 standard deviations below a group of children with intellectual deficits. School-related success was a composite score of the mathematics grade, the language grade and school type. Children with poor mathematics achievement showed similar school-related success to children with intellectual deficits. Furthermore, they scored significant lower than children without mathematical difficulties and average intelligence. Older children with mathematical difficulties (4th to 5th grade) showed a poorer prognosis than children attending grade 2 or 3. Conclusion: Poor mathematics achievement is a considerable developmental risk. Large longitudinal studies into adult-hood with strict MLD definition are needed to evaluate predictors of successful developmental courses.

Methods: In 1,6 children aged 9-11 years the reaction time, the number of mistakes and EEG (19 scalp electrodes) were measured in three experiments (verbal and nonverbal). The EEG data was baseline-corrected and after a fast fourier transformation, analyzed with the coherence tool of the Brainvision(C) Software. Results: The dyslexic group made more mistakes than the control group on all tasks but their reaction times were significantly longer only on the verbal tasks. There were no coherence differences on the nonverbal task. On the language-dependent tasks the dyslexics showed higher total-frontal and lower left-frontal coherences only in the theta-frequency range, while in the alpha and beta frequency ranges coherences did not differ. Conclusions: A language-dependent cognitive automatizational deficit in the dyslexic group is assumed that is depicted by the higher synchronization of total-frontal coherences (involvement of the central executive) and is based on the less established functional coupling of cortical subsystems for language processing Y1 - 2003 SN - 1422-4917 ER -
