Group Psychoeducation for Parents of Adolescents with Eating Disorders: The Aachen Program

Family-based treatment in adolescents and individual psychoeducation in adults are accepted components in a multimodal treatment of eating disorders. However, only few studies have been conducted on the use of parent-based psychoeducation. This paper presents the structure and content, as well as a preliminary evaluation, of a group psychoeducation program for parents of adolescent patients with eating disorders. The program is limited to five 90-minute sessions and aimed at increasing the parents’ understanding of the disorder and promoting high transparency with regard to our treatment principles. The vast majority of parents rated the group psychoeducation as helpful in coping with their child's disorder and would recommend others to take part in the program.     

Attentional functions in children and adolescents with ADHD,depressive disorders,and the comorbid condition

Background: Attention‐deficit hyperactivity disorder (ADHD) and depressive disorders (DDs) often co‐occur in children and adolescents, but evidence on the respective influence of these disorders on attention parameters is inconsistent. This study examines the influence of DDs on ADHD in a model‐oriented approach that includes selectivity and intensity attention parameters. Methods: Ten‐ to fifteen‐year‐olds with ADHD (n = 63), DDs (n = 61), ADHD+DDs (n = 64), and healthy controls (n = 64) completed a battery of tests including five neuropsychological tasks (i.e., alertness, sustained attention, divided attention, go/no‐go, and attentional set‐shifting). Results: All clinical groups showed attentional problems, especially in more complex attentional tasks and in the intensity aspects of attention. We observed the most severe attentional impairments in children with ADHD that was independent from a comorbid DD. Conclusion: The clinical groups were significantly different from the healthy control group, especially in more complex attentional tasks and in the intensity aspects of attention. Some differences between ADHD, DDs and ADHD+DDs groups were detected on neuropsychological attentional performance, but the effects were not strong enough to differentiate the clinical groups from each other.     

Effects of the DRD4 genotype on neural networks associated with executive functions in children and adolescents

Genetic variants within the dopamine D4 receptor gene (DRD4) are among the strongest and most consistently replicated molecular genetic findings in attentional functioning as well as attention deficit hyperactivity disorder (ADHD). Functionally, the 7-repeat allele of the DRD4-48 base pair repeat gene leads to a sub-sensitive postsynaptic D4 receptor, which is expressed at a particularly high density in the frontal lobes. We used fMRI to investigate the influence of the 7-repeat allele on BOLD (Blood Oxygen Level Dependency) responses in 26 healthy children and adolescents while they performed a combined stimulus-response Incompatibility Task (IC) and a Time Discrimination Task (TT). 7-repeat non-carriers exhibited increased neural activation of the left middle and inferior frontal gyrus (IFG) in the IC and greater cerebellar activation in the TT. Furthermore, the 7-repeat non-carriers exhibited a stronger coupling in haemodynamic responses between left IFG and the anterior cingulate cortex (ACC) during the IC and between cerebellar activation and brain regions that have high DRD4 density, including the IFG and the ACC during the TT. Our results indicate that the 7-repeat allele influences both regional brain activation patterns as well as connectivity patterns between neural networks of incompatibility and temporal processing.
