Transcranial direct-current stimulation enhances implicit motor sequence learning in persons with Parkinson's disease with mild cognitive impairment

Implicit motor sequence learning (IMSL) is affected in Parkinson's disease (PD). Research in healthy young participants shows the potential for transcranial direct-current stimulation (tDCS) over the primary motor cortex (M1) to enhance IMSL. In PD, only null effects have been reported to date. We determined concurrent, short-term, and long-term effects of anodal tDCS over M1 on IMSL, as measured by the serial reaction time (SRT) task, in persons with PD with mild cognitive impairment (MCI). Concurrent (anodal/sham tDCS intervention during the SRT task), short-term (5 min post-intervention), and long-term (1 week post-intervention) effects on IMSL were evaluated in persons with idiopathic PD (Hoehn and Yahr stage II-III) with MCI. Results of 11 persons with PD (8 men and 3 women; mean age = 77.1 years; mean disease duration = 7.7 years) showed significant IMSL in the anodal (p = .016), but not in the sham tDCS condition (p = .937). Post-hoc analyses showed that IMSL reached statistical significance at 1 week post-intervention (p < .001). Anodal tDCS over M1 exerted beneficial effects on IMSL in persons with PD with MCI, in particular one week post-intervention. Our study is the first to report a positive effect of tDCS on IMSL in PD. Further research should include a larger, more cognitively diverse sample and additional follow-up periods.     

A majority world perspective on human development: Commemorating the achievements of Çiğdem Kağıtçıbaşı

This obituary draws attention to the contributions by Çi?dem Ka??tç?ba?? in the fields of developmental psychology and cross-cultural psychology. Three themes are mentioned: research on the value of children, early childhood enrichment programs, and conceptualization of the autonomous related self.     

Childhood problem behaviours as precursors of drinking to intoxication trajectories – from age 1.5 to 19

Objective: We examined behaviour problem precursors (i.e. internalising and externalising) in childhood (ages 1.5 to 8.5) and early adolescence (age 12.5) and consequences (i.e. harmful alcohol use) in emerging adulthood (age 19), of developmental trajectories of drinking to intoxication across adolescence (ages 14.5–19).

Design and outcome measures: Data from 921 children and their parents followed for 18 years from the population-based Tracking Opportunities and Problems (TOPP) Study were used to examine adolescent trajectories of drinking to intoxication. Logistic regression was used to examine predictors of trajectory group membership.

Results: We identified 3 trajectory classes: low / abstainer (41%), late onset high (31%) and early onset high (28%) using latent class analyses. Logistic regression analyses showed that childhood high externalising characterised early onset of intoxication vs. other classes, while early adolescence externalising discriminated both early and late onset of intoxication. High early childhood internalising characterised those consistently low or abstinent on alcohol intoxication, while early adolescent internalising characterised those having an early onset of intoxication. However, after additional adjustment for co-occurring externalising, there were no evidence for a link between early adolescent internalising and intoxication.

Conclusions: The findings suggest that both child and early adolescent-focused prevention efforts may be warranted.     

Congenital heart disease: A primer for the pediatric neuropsychologist

Congenital heart disease (CHD) affects millions of people worldwide, including over one million children in the United States. Approximately 25% of children born with CHD require intensive surgical intervention within the first year of life. Despite improved rates of survival into adulthood – rates that exceed 90% in the modern era – children and adolescents with CHD remain at risk for neurological injury and a range of neurobehavioral and psychosocial challenges that pose a threat to quality of life across the lifespan. Consequently, as experts in both clinical psychology and brain development, neuropsychologists are becoming increasingly involved in cardiac follow-up and monitoring to promote optimal developmental outcomes. The primary objective of this paper is to provide an evidence-based, clinically-oriented primer on CHD for pediatric neuropsychologists working with this growing population of survivors. Following an introduction to current standard-of-care guidelines for managing children and adolescents with CHD, we present an overview of brain development within the context of CHD, review neuropsychological outcomes, examine factors influencing variability in outcomes, and discuss implications and strategies for clinical assessment.     

Échelle de stigmatisation familiale dans la maladie d’Alzheimer (ESF-MA) : une adaptation et validation française

According to scientific research, individuals diagnosed with neurodegenerative dementia of the Alzheimer type and their surroundings (family, family caregiver), experience a phenomenon of family stigmatization of which there are many consequences. Not only can they experience emotional reactions such as fear, anxiety, more depressive symptoms, but they can also face discrimination with a sense of care giving burden and be the result of social relationships avoidance. These effects lead to reduce family life quality. At the same time, scientific studies reveal that stigma acts on a personal, associative (family), public and on a structural level. Their joint perception seems necessary to apprehend their synergy and to adapt interventions. However, in the AD context, no tool exists in the French language to measure perceived family stigma on different levels. To fill this gap, we analyzed the construct validity (intra-concept validity), an aspect of the divergent validity, concurrent validity as well as the reliability of the AD family stigma scale (ESF-MA) in the French context. The results of the principal component analysis (n = 263 family caregivers) reveal 10 factors divided into 3 dimensions (intra-personal, public and structural) that explain 57 % of the total variance. The validity of the construct like the reliability represents satisfying results. The measurement of the family stigma by the ESF-MA presents an opportunity to complete clinical observations among family caregivers of people diagnosed with AD.     

Evaluating a novel intervention to reduce trauma symptoms and sexual risk taking: qualitative exit interviews with sexual minority men with childhood sexual abuse

Childhood sexual abuse (CSA) continues to affect sexual minority men (SMM) at disproportionate levels and contributes to multiple negative health outcomes, including sexual-risk taking and HIV acquisition. This paper presents qualitative evaluative feedback from SMM (N = 9) who participated in a 10-session Cognitive Behavioral Therapy-Trauma and Sexual Health (CBT-TSH) intervention to reduce CSA-related posttraumatic stress reaction and distress. The treatment was designed to increase accurate sexual risk appraisals and to improve self-care health behaviors related to HIV/STI acquisition. The researchers identified four emerging themes: (1) motivation to participate, (2) response to cognitive therapy, (3) process of change, and (4) considerations for intervention improvement. These qualitative findings provide useful feedback on the acceptability of an innovative program that integrates CBT for trauma related to CSA with sexual risk-reduction counseling.     

Quality of life and depression in haemodialysis patients

Chronic kidney disease is associated with a high prevalence of depression, which increases inversely with the glomerular filtration rate. This paper aims to evaluate the factors associated with a low quality of life and depression in patients on haemodialysis. Two hundred patients undergoing haemodialysis answered the Medical Outcomes Study 36 – Item Short – Form Health Survey (SF-36) and Beck Depression Inventory (BDI). Clinical and laboratory variables were analysed and correlated with these two tools. The prevalence of depression was 29%. Anaemia and hypoalbuminemia were independent risk factors for depression. All SF-36 domains showed worse results in patients with depression, and the pain domain presented the highest correlation. Our findings provide evidence that patients on haemodialysis have a low quality of life and a high prevalence of depression. A greater number of comorbidities, an excessive number of medications, diabetes mellitus, anaemia and hypoalbuminemia were associated with a reduced quality of life.     

Investigation into New Zealand early childhood teachers’ perspectives on spirituality and wairua in teaching

The New Zealand early childhood Te Whāriki Curriculum’s vision statement draws attention to the responsibility teachers have to create environments in which children can develop holistically; including spiritually. This paper outlines the findings from a small qualitative research project that explored teachers’ perspectives on their understanding of spirituality and ‘wairua’ and the role they have in fostering these aspects in children’s development. Participants were in agreement that the concept of wairua and spiritualty are interwoven with both being about the spirit, soul, inner being, heart, the sum of who you are. Participants were in agreement that fostering this aspect of a child’s development was part of a teacher’s responsibility. All respondents identified implications for their practice which included having environments that were inviting, stress free, engaging and filled with natural resources. The study highlighted that their initial teacher education programmes failed to cover these aspects in spirituality in any depth.     

Childhood sexual abuse trauma-causing dynamics experienced by women survivors: A scoping literature review

This scoping literature review reports on the major themes to emerge from 23 retrospective studies on the trauma-causing dynamics experienced by women survivors of a historical childhood sexual abuse (CSA) trauma. We identified the studies from searching the following data bases for the period 1983–2016: EbscoHost (Academic Search Premiere, Africa-Wide Information, E-Journals, ERIC, PsycARTICLES, PsycINFO, SocINDEX), SAePublications, Science Direct, CrossRef (APA PsycNET), Google scholar (ResearchGate), PubMed Central, and Cochrane Reviews. For the selection criteria, we included empirical studies on self-reported trauma-causing dynamics experienced by women survivors, without restriction on method of study. Results from the thematic analysis of findings suggest the women survivors appear to be living with historical traumatic sexualisation, betrayal of trust, social stigmatisation, powerlessness, developmental arrest, and revictimisation. Historical traumas should be considered in counselling support interventions with women self-reporting CSA.
