Hyperactive Behaviour

The Preschool Behaviour Questionnaire has been used widely to assess children's aggressive, anxious, and hyperactive behaviour. Items from the Prosocial Behaviour Questionnaire were added to create a prosocial scale. The resulting questionnaire was administered to teachers of three large samples of kindergarten children and shown to have three stable, orthogonal components disruptive (13 items): anxious (6 items); and prosocial (10 items). Mother and peer assessments of children were used to investigate concurrent and predictive validity. Concurrent data showed that the disruptive component was highly correlated with peer assessments and moderately correlated with mother assessments; the prosocial component was moderately correlated with peer assessments but marginally correlated with mother assessments, whereas the anxious component was marginally correlated with peer assessments and moderately correlated with mother assessments. From a predictive perspective it was shown that highly disruptive boys in kindergarten who were prosocial, were assessed by mothers and teachers at age 9 to be better adjusted than highly disruptive boys in kindergarten who were non-prosocial.

Abstract. Objective: The purpose of the present study was the analysis of the association between consumption of candy and fruit gums, diagnosis of attention deficit hyperactivity disorder (ADHD), and behavioural problems. Methods: In total, 1,187 children and adolescents of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) were analyzed. Results: It was observed that children and adolescents with ADHD as compared to healthy controls (HC) reported to consume more frequently and higher amounts of candy and fruit gums and that hyperactivity was associated with frequent candy and fruit gum consumption. Conclusions: Because with the present design no conclusions on causality or directionality of the found associations could be drawn, results are discussed quite broadly in the light of several previously published interpretations, also to serve as a generator for further research. One more innovative speculation is that children and adolescents with ADHD may consume more frequently candy and fruit gums in order i) to compensate for their higher needs of energy resulting from hyperactive behaviour and/or ii) to compensate for the ADHD-typical deficits in the “reward cascade”.

Insight Into

Mermithids (phylum Nematoda) and hairworms (phylum Nematomorpha) somehow drive their arthropod hosts into water, which is essential for the worms' survival after egression. The mechanisms behind this behavioural change have been investigated in hairworms, but not in mermithids. Establishing a similar mechanistic basis for host behavioural change between these two distantly related parasitic groups would provide strong convergent evidence for adaptive manipulation and insight into how these parasites modify and/or create behaviour. Here, we search for this convergence, and also contrast changes in physiology between hosts infected with immature and mature mermithids to provide the first ontogenetic evidence for adaptive manipulation by disentangling host response and pathology from the parasite's apparent manipulative effects. We used SWATH-mass spectrometry on brains of Forficula auricularia (earwig) and Bellorchestia quoyana (sandhopper), infected with the mermithids Mermis nigrescens and Thaumamermis zealandica , respectively, at both immature and mature stages of infection, to quantify proteomic changes resulting from mermithid infection. Across both hosts (and hairworm-infected hosts, from earlier studies), the general function of dysregulated proteins was conserved. Proteins involved in energy generation/mobilization were dysregulated, corroborating reports of erratic/hyperactive behaviour in infected hosts. Dysregulated proteins involved in axon/dendrite and synapse modulation were also common to all hosts, suggesting neuronal manipulation is involved in inducing positive hydrotaxis. Furthermore, downregulation of CamKII and associated proteins suggest manipulation of memory also contributes to the behavioural shift.
