Die Grundlage der Anwendung von Neurofeedback bei dieser St{\"o}rung besteht darin, dass die Kinder Auff{\"a}lligkeiten in ihrem EEG zeigen. Dort treten im Vergleich zu unauff{\"a}lligen Kindern vermehrt Theta-Gehirnwellen und weniger Beta-Gehirnwellen auf. Mittels Neurofeedback wird versucht, die Gehirnfunktionen zu korrigieren. Zahlreiche Einzellfallstudien best{\"a}tigen die Wirksamkeit dieser Therapiemethode bei der AD/HS-Behandlung. Bisher wurde jedoch keine Studie ver{\"o}ffentlicht, in der die Wirksamkeit von Neurofeedback mit einer Placebogruppe verglichen wurde. Ziel der vorliegenden Studie war es, die Wirksamkeit eines Theta/Beta-Neurofeedbacks (NF) bei der Behandlung von AD/HS-Kindern zu {\"u}berpr{\"u}fen und mit einem EMG-Biofeedback (BF) als Placebobedingung zu vergleichen. Es wurden 35 ADHS-Kinder (6 -14 Jahre; 26 Jungen und 9 M{\"a}dchen) untersucht. Nach Standarddiagnostik und Vergabe der AD/HS-Diagnose durch einen unabh{\"a}ngigen Psychotherapeuten wurden die Kinder per Zufall zwei Gruppen (NF: n = 18 bzw. BF: n = 17) zugeteilt. Alle Kinder beider Gruppen erhielten ein 30 Sitzungen umfassendes Training mittels Theta/Beta-Neurofeedback bzw. EMG-Biofeedback. Unmittelbar vor und nach dem Training wurden Intelligenz- bzw. Aufmerksamkeitsleistungen untersucht und Einsch{\"a}tzungen des Verhaltens von Eltern und Lehrern erhoben. Im Anschluss an das Training erfolgte eine erneute diagnostische Einsch{\"a}tzung durch einen unabh{\"a}ngigen Psychotherapeuten. Die EEG-Daten in der NF-Gruppe zeigen eine Reduktion der Theta/Beta-Quotienten im Laufe der NF-Sitzungen. Die EMG-Daten zeigen f{\"u}r die EMG-Biofeedback-Bedingung gleichfalls eine Reduktion der EMG-Amplitude. Die Ergebnisse der zweifaktoriellen Varianzanalysen mit Messwiederholung auf einem Faktor zeigen f{\"u}r die angewendeten diagnostischen Verfahren die erwarteten signifikanten Interaktionen zwischen Messzeitpunkt und Gruppe. Die Ergebnisse des t-Tests zeigen signifikante Verbesserungen in der Aufmerksamkeitsleistung, dem Intelligenzniveau und im Verhalten der Kinder aus der NF-Gruppe im Vergleich zu den Resultaten des Pr{\"a}-Tests. Die EMG-Biofeedbackgruppe zeigt mit Ausnahme einer Erh{\"o}hung des Arbeitstempos in den Paper-Pencil-Aufmerksamkeitstests (die im CPT nicht repliziert werden konnte) keine signifikanten Verbesserungen relativ zum Pr{\"a}-Test. Nach dem Training erhielten 55,6 \% (n = 10) der AD/HS-Kinder aus der Neurofeedbackgruppe und 23,5 \% (n = 4) der Kinder aus der EMG-Biofeedbackgruppe keine AD/HS-Diagnose nach den Kriterien der ICD-10. Der Chi-Quadrat-Test zeigt jedoch lediglich einen tendenziell bedeutsamen Unterschied (p = .086). Insgesamt best{\"a}tigen die Ergebnisse die Wirksamkeit des Neurofeedbacks bei der Behandlung von ADHS-Kindern im Vergleich mit einer Placebogruppe. Weitere Studien in diesem Bereich sind notwendig, um die Wirksamkeit des Neurofeedbacktrainings im Vergleich zu einer Placebomethode bei der ADHS-Behandlung zu untersuchen.}, language = {de} } @article{BakhshayeshHaenschWyschkonetal.2011, author = {Bakhshayesh, Ali Reza and H{\"a}nsch, Sylvana and Wyschkon, Anne and Rezai, Mohammad Javad and Esser, G{\"u}nter}, title = {Neurofeedback in ADHD a single-blind randomized controlled trial}, series = {European child and adolescent psychiatry : offical journal of the European Society for Child and Adolescent Psychiatry}, volume = {20}, journal = {European child and adolescent psychiatry : offical journal of the European Society for Child and Adolescent Psychiatry}, number = {9}, publisher = {Springer}, address = {New York}, issn = {1018-8827}, doi = {10.1007/s00787-011-0208-y}, pages = {481 -- 491}, year = {2011}, abstract = {Neurofeedback treatment has been demonstrated to reduce inattention, impulsivity and hyperactivity in children with attention deficit/hyperactivity disorder (ADHD). However, previous studies did not adequately control confounding variables or did not employ a randomized reinforcer-controlled design. This study addresses those methodological shortcomings by comparing the effects of the following two matched biofeedback training variants on the primary symptoms of ADHD: EEG neurofeedback (NF) aiming at theta/beta ratio reduction and EMG biofeedback (BF) aiming at forehead muscle relaxation. Thirty-five children with ADHD (26 boys, 9 girls; 6-14 years old) were randomly assigned to either the therapy group (NF; n = 18) or the control group (BF; n = 17). Treatment for both groups consisted of 30 sessions. Pre- and post-treatment assessment consisted of psychophysiological measures, behavioural rating scales completed by parents and teachers, as well as psychometric measures. Training effectively reduced theta/beta ratios and EMG levels in the NF and BF groups, respectively. Parents reported significant reductions in primary ADHD symptoms, and inattention improvements in the NF group were higher compared to the control intervention (BF, d(corr) = -.94). NF training also improved attention and reaction times on the psychometric measures. The results indicate that NF effectively reduced inattention symptoms on parent rating scales and reaction time in neuropsychological tests. However, regarding hyperactivity and impulsivity symptoms, the results imply that non-specific factors, such as behavioural contingencies, self-efficacy, structured learning environment and feed-forward processes, may also contribute to the positive behavioural effects induced by neurofeedback training.}, language = {en} } @article{BondueEsser2015, author = {Bond{\"u}, Rebecca and Esser, G{\"u}nter}, title = {Justice and rejection sensitivity in children and adolescents with ADHD symptoms}, series = {European child and adolescent psychiatry : offical journal of the European Society for Child and Adolescent Psychiatry}, volume = {24}, journal = {European child and adolescent psychiatry : offical journal of the European Society for Child and Adolescent Psychiatry}, number = {2}, publisher = {Springer}, address = {New York}, issn = {1018-8827}, doi = {10.1007/s00787-014-0560-9}, pages = {185 -- 198}, year = {2015}, abstract = {Justice sensitivity captures individual differences in the frequency with which injustice is perceived and the intensity of emotional, cognitive, and behavioral reactions to it. Persons with ADHD have been reported to show high justice sensitivity, and a recent study provided evidence for this notion in an adult sample. In 1,235 German 10- to 19-year olds, we measured ADHD symptoms, justice sensitivity from the victim, observer, and perpetrator perspective, the frequency of perceptions of injustice, anxious and angry rejection sensitivity, depressive symptoms, conduct problems, and self-esteem. Participants with ADHD symptoms reported significantly higher victim justice sensitivity, more perceptions of injustice, and higher anxious and angry rejection sensitivity, but significantly lower perpetrator justice sensitivity than controls. In latent path analyses, justice sensitivity as well as rejection sensitivity partially mediated the link between ADHD symptoms and comorbid problems when considered simultaneously. Thus, both justice sensitivity and rejection sensitivity may contribute to explaining the emergence and maintenance of problems typically associated with ADHD symptoms, and should therefore be considered in ADHD therapy.}, language = {en} } @article{HennigSchrammLinderkamp2017, author = {Hennig, Timo and Schramm, Satyam Antonio and Linderkamp, Friedrich}, title = {Cross-informant disagreement on behavioral symptoms in adolescent attention-deficit/hyperactivity disorder and its impact on treatment effects}, series = {European Journal of Psychological Assessment}, volume = {34}, journal = {European Journal of Psychological Assessment}, number = {2}, publisher = {Hogrefe}, address = {G{\"o}ttingen}, issn = {1015-5759}, doi = {10.1027/1015-5759/a000446}, pages = {79 -- 86}, year = {2017}, abstract = {In assessing adolescent behavior difficulties, parents, teachers, and the adolescents themselves are key informants.

In two recent longitudinal studies the CBCL-DP in childhood was associated with heightened rates of comorbid psychiatric disorders, among them bipolar disorder, an increased risk for suicidality, and marked psychosocial impairment at young-adult follow-up. This is the first study outside the US that examines the longitudinal course of the CBCL-DP. Methods: We studied the diagnostic and functional trajectories and the predictive utility of the CBCL-DP in the Mannheim Study of Children at Risk, an epidemiological cohort study on the outcome of early risk factors from birth into adulthood. A total of 325 young adults (151 males, 174 females) participated in the 19-year assessment. Results: Young adults with a higher CBCL-DP score in childhood were at increased risk for substance use disorders, suicidality and poorer overall functioning at age 19, even after adjustment for parental education, family income, impairment and psychiatric disorders at baseline. Childhood dysregulation was not related to bipolar disorder in young adulthood. The CBCL-DP was neither a precursor of a specific pattern of comorbidity nor of comorbidity in general. Conclusions: Children with high CBCL-DP values are at risk for later severe, psychiatric symptomatology. The different developmental trajectories suggest that the CBCL-DP is not simply an early manifestation of a single disease process but might rather be an early developmental risk marker of a persisting deficit of self-regulation of affect and behavior.}, language = {en} } @article{HolzBoeckerSchlierJennenSteinmetzetal.2018, author = {Holz, Nathalie E. and Boecker-Schlier, Regina and Jennen-Steinmetz, Christine and Hohm, Erika and Buchmann, Arlette F. and Blomeyer, Dorothea and Baumeister, Sarah and Plichta, Michael M. and Esser, G{\"u}nter and Schmidt, Martin and Meyer-Lindenberg, Andreas and Banaschewski, Tobias and Brandeis, Daniel and Laucht, Manfred}, title = {Early maternal care may counteract familial liability for psychopathology in the reward circuitry}, series = {Social Cognitive and Affective Neuroscience}, volume = {13}, journal = {Social Cognitive and Affective Neuroscience}, number = {11}, publisher = {Oxford Univ.

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.}, language = {en} } @article{KleinKruegelRisseetal.2015, author = {Klein, Angela Ines and Kruegel, Andre and Risse, Sarah and Esser, G{\"u}nter and Engbert, Ralf and Pereira, Vera Wannmacher}, title = {The processing of pronominal anaphora by children that have attention deficit hyperactivity disorder or dyslexia: a study through the analysis of eye movements}, series = {Letras de hoje}, volume = {50}, journal = {Letras de hoje}, number = {1}, publisher = {PUCRS}, address = {Porto Alegre}, issn = {0101-3335}, pages = {40 -- 48}, year = {2015}, abstract = {The aim of this work was to verify the processing of pronominal anaphora by children that have attention deficit hyperactivity disorder or dyslexia.

The reasons for this difference remain unclear. Although sex might play a moderating role, it has not yet been examined in this regard. In an epidemiological cohort study from birth to young adulthood, childhood ADHD diagnoses were assessed at the ages of 4.5, 8, and 11 years based on parent ratings. Sex-specific development of ADHD symptoms was analyzed from the age of 15 to 25 years via self-reported ADHD symptoms in participants with (n = 47) and without childhood ADHD (n = 289) using a random coefficient regression model. The congruence between parent reports and adolescents' self-ratings was examined, and the role of childhood ADHD diagnosis, childhood OCC/CD, and childhood internalizing disorder as possible sex-specific predictors of self-reported ADHD symptoms at age 25 years was investigated. With regard to self-reported ADHD symptoms, females with a childhood ADHD diagnosis reported significantly more ADHD symptoms compared to females without childhood ADHD and males with and without ADHD throughout adolescence and young adulthood. In contrast, males with childhood ADHD did not differ from control males either at age 15 or at age 25 years. Only in females did a childhood diagnosis of an externalizing disorder (ADHD and CD/ODD) predict self-reported ADHD symptoms by age 25 years. Our findings suggest that self-reports of young adults with a childhood diagnosis of ADHD are influenced by sex. Specifically, females with childhood ADHD report increased levels of ADHD symptoms upon reaching adulthood. To correctly evaluate symptoms and impairment in this subgroup, other, more objective, sources of information may be advisable, such as neurophysiological measures.}, language = {en} }
