Self-regulatory behaviors in children with Down syndrome and typically developing children measured using the Goodman Lock Box

Self-regulation has been identified as an area of difficulty for those with mental retardation. The Goodman Lock Box provides measures of two critical aspects of self-regulation-planfulness and maintenance of goal-directed behavior. In this study, the Lock Box performance of 25 children with Down syndrome was compared with that of 43 typically developing children, matched for mental age (24-36 months). Children in both groups showed similar levels of competence, planfulness and distractibility. However, children with Down syndrome displayed more task-avoidant behavior. Some issues related to the measurements obtained from the Lock Box are raised. (C) 2003 Elsevier Science Ltd. All rights reserved.

Gender differences in the relationship between offending, self-harm and depression in adolescence and young adulthood

Criminal offending and poor mental health are both recognised as important social problems warranting prevention and intervention efforts. Although there is some evidence for comorbidity between these problems, little research has examined the causal relationship between offending and mental health, particularly for young people. The present investigation addresses these issues by using data from the Sibling Study, a longitudinal investigation of delinquency as self-reported by 731 adolescents and young adults in south-east Queensland, Australia. The results suggest that for young women, but not men, offending behaviours (including the use of illicit drugs) lead to increases in self-harm and depression. Conversely, poor mental health, as indicated by having low self-esteem, a poor future outlook, and a belief that life is very confusing, does not influence subsequent levels of offending for either sex. The implications for prevention and intervention are discussed, with emphasis on the need for the criminal justice system to provide mental health services to young female offenders.

Vocational rehabilitation in psychiatry: A re-evaluation

Objective: To highlight the vocational gap in the provision of psychiatric rehabilitation, to outline the goals and conceptual framework of psychiatric rehabilitation, and to discuss rehabilitation interventions with specific reference to vocational rehabilitation and the evidence base for supported employment. Conclusions and service implications: Vocational psychiatric rehabilitation has been a neglected area of practice in Australian psychiatry. Psychiatric treatment needs to adopt a more balanced approach in the provision of a range of services, including vocational rehabilitation, in order to improve long-term outcomes for people suffering from psychiatric disability. A vocational focus should be included in psychiatric rehabilitation and better integration between mental health services and vocational services needs to take place. Supported employment is an evidence-based practice that is designed to help people with psychiatric disabilities participate as much as possible in the competitive job market.

Evaluating parent use of functional communication training to replace and enhance prelinguistic behaviours in six children with developmental and physical disabilities

Purpose: To evaluate parent use of functional communication training (FCT) to replace and enhance prelinguistic behaviours in six young children with developmental and physical disabilities. Method: Initially, the communicative functions of the children's prelinguistic behaviours were assessed by parent interviews. Three communication functions were identified for each child and intervention goals to replace or enhance the child's existing prelinguistic behaviours were developed in consultation with parents. After a baseline phase, parents received training on implementation of FCT. Intervention was staggered across the three communicative functions in a multiple-probe design. Results: Intervention was associated with increases in the replacement communication behaviour. Treatment gains were generally maintained at the monthly follow-ups. Conclusion: The results suggest that parents can use FCT to enhance communication skills in children with developmental and physical disabilities.

Moving molecules: mRNA trafficking in mammalian oligodendrocytes and neurons

Numerous mRNA molecules are localized in regions of the dendrites of neurons, some moving along dendrites in response to synaptic activity. The proteins encoded by these RNAs have diverse functions, including participation in memory formation and long-term potentiation. Recent experiments have shown that a cytoplasmic RNA trafficking pathway described for oligodendrocytes also operates in neurons. Transported RNAs possess a cis-acting element that directs them to granules, which are transported along microtubules by the motor proteins kinesin and dynein. These RNA molecules are recruited to the cytoplasmic transport granules by cooperative interaction with a cognate trans-acting factor. mRNAs containing the 11-nucleotide A2RE11 or 21-nucleotide A2RE sequences bind heterogeneous nuclear ribonucleoproteins A2 and A3, which are abundant in the brain. Mutations in this cis-acting element that weaken its interaction with hnRNP A2 also interfere with RNA trafficking. Several dendritically localized mRNAs, including those encoding calcium-calmodulin-dependent protein kinase 11 a subunit and neurogranin, possess A2RE-like sequences, suggesting that they may be localized by interaction with these heterogeneous nuclear ribonucleoproteins. Calcium-calmodulin-dependent protein kinase 11 a subunit is of particular interest: Its RNA is transported in depolarized neurons, and the protein it encodes is essential for establishing long-term memory. Several other cis-acting sequences and trans-acting factors that participate in neuronal RNA localization have been discovered.

On dendrites in Down syndrome and DS murine models: a spiny way to learn

Since the discovery in the 1970s that dendritic abnormalities in cortical pyramidal neurons are the most consistent pathologic correlate of mental retardation, research has focused on how dendritic alterations are related to reduced intellectual ability. Due in part to obvious ethical problems and in part to the lack of fruitful methods to study neuronal circuitry in the human cortex, there is little data about the microanatomical contribution to mental retardation. The recent identification of the genetic bases of some mental retardation associated alterations, coupled with the technology to create transgenic animal models and the introduction of powerful sophisticated tools in the field of microanatomy, has led to a growth in the studies of the alterations of pyramidal cell morphology in these disorders. Studies of individuals with Down syndrome, the most frequent genetic disorder leading to mental retardation, allow the analysis of the relationships between cognition, genotype and brain microanatomy. In Down syndrome the crucial question is to define the mechanisms by which an excess of normal gene products, in interaction with the environment, directs and constrains neural maturation, and how this abnormal development translates into cognition and behaviour. In the present article we discuss mainly Down syndrome-associated dendritic abnormalities and plasticity and the role of animal models in these studies. We believe that through the further development of such approaches, the study of the microanatomical substrates of mental retardation will contribute significantly to our understanding of the mechanisms underlying human brain disorders associated with mental retardation.

Increased expression of the MBP mRNA binding protein HnRNP A2 during oligodendrocyte differentiation

Heterogeneous nuclear ribonucleoprotein (hnRNP) A2, a trans-acting factor that mediates intracellular trafficking of myelin basic protein (MBP) mRNA to the myelin compartment in oligodendrocytes, is most abundant in the nucleus, but shuttles between the nucleus and cytoplasm. In the cytoplasm, it is associated with granules that transport mRNA from the cell body to the processes of oligodendrocytes. We found that the overall level of hnRNP A2 increased in oligodendrocytes as they differentiated into MBIP-positive cells, and that this augmentation was reflected primarily in the cytoplasmic pool of hnRNP A2 present in the form of granules. The extranuclear distribution of hnRNP A2 was also observed in brain during the period of myelination in vivo. Methylation and phosphorylation have been implicated previously in the nuclear to cytoplasmic distribution of hnRNPs, so we used drugs that block methylation and phosphorylation of hnRNPs to assess their effect on hnRNP A2 distribution and mRNA trafficking. Cultures treated with adenosine dialdehyde (AdOx), an inhibitor of S-adenosyl-L-homocysteine hydrolase, or with 5,6-dichloro-1-beta-D-ribofuranosylbenzimidazole (DRB), a drug that inhibits casein kinase 2 (CK2), maintained the preferential nuclear distribution of hnRNP A2. Treatment with either drug affected the transport of RNA trafficking granules that remained confined to the cell body. (C) 2004 Wiley-Liss, Inc.

Finding meaning in parenting a child with Asperger syndrome: correlates of sense making and benefit finding

This study explored the nature of two construals of meaning, benefit finding and sense making, in parents of a child with Asperger syndrome, and examined relations between both meaning constructs and the Double ABCX family stress model variables (initial stressor and pile-up of demands, appraisal, social support, coping strategies and adjustment) [H.I. McCubbin, J.M. Patterson, Social Stress and the Family: Advances and Developments in Family Stress Theory and Research, Haworth, New York, 1983, pp. 7-37]. A total of 59 parents completed questionnaires. Content analyses of parents' responses to questions inquiring about gains and sense making explanations revealed 8 benefit and 12 sense making themes. Results of correlations indicated that one or more of the meaning variables were related to each of the Double ABCX model predictors of parental adjustment. The meaning variables were positively related to adaptive coping processes: social support, self-efficacy, and problem-focused and emotional approach coping strategies. (C) 2004 Elsevier Ltd.

Attitudes towards the sexuality of adults with an intellectual disability: parents, support staff, and a community sample

Attitudes toward the sexuality of adults with intellectual disability were assessed in parents and carers of adults with intellectual disability and in a community sample. An instrument that contained items relating to eight aspects of sexuality (sexual feelings, sex education, masturbation, personal relationships, sexual intercourse, sterilisation, marriage, and parenthood) was developed and found to have good internal consistency and test-retest reliability. Age was associated with attitudes, with those aged 60 and above holding more conservative attitudes. Parents and staff differed in their attitudes, with parents holding more conservative attitudes. This difference was the product of age differences between the groups; nevertheless it may produce some confusion for adults with intellectual disability unless it is addressed appropriately. Both parent and staff groups were less positive about parenthood than about other aspects of sexuality, however the community group did not differ in their views when attitudes towards parenthood were compared with the remaining items Of the scale.

Alterations in the phenotype of neocortical pyramidal cells in the Dyrk1A+/- mouse

The gene encoding the dual-specificity tyrosine-regulated kinase DYRK1A maps to the chromosomal segment HSA21q22.2, which lies within the Down syndrome critical region. The reduction in brain size and behavioral defects observed in mice lacking one copy of the murine homologue Dyrk1A (Dyrk1A+/-) support the idea that this kinase may be involved in monosomy 21 associated mental retardation. However, the structural basis of these behavioral defects remains unclear. In the present work, we have analyzed the microstructure of cortical circuitry in the Dyrk1A+/- mouse and control littermates by intracellular injection of Lucifer Yellow in fixed cortical tissue. We found that labeled pyramidal cells were considerably smaller, less branched and less spinous in the cortex of Dyrk1A+/- mice than in control littermates. These results suggest that Dyrk1A influences the size and complexity of pyramidal cells, and thus their capability to integrate information. (c) 2005 Elsevier Inc. All rights reserved.
