ADHD and autism symptoms in youth: a network analysis.

J Child Psychol Psychiatry 2021 May 13. Epub 2021 May 13.

Departamento de Psiquiatria da Faculdade de Medicina FMUSP, Universidade de São Paulo, São Paulo, Brazil.

Background: Previous research investigating the overlap between attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (henceforth, autism) symptoms in population samples have relied on latent variable modeling in which averaged scores representing dimensions were derived from observed symptoms. There are no studies evaluating how ADHD and autism symptoms interact at the level of individual symptom items.

Methods: We aimed to address this gap by performing a network analysis on data from a school survey of children aged 6-17 years old (N = 7,405). Read More

Machine learning model on heart rate variability metrics identifies asymptomatic toddlers exposed to Zika virus during pregnancy.

Physiol Meas 2021 May 13. Epub 2021 May 13.

GYNOB, University of Washington School of Public Health, Seattle, Washington, UNITED STATES.

Objective Although the Zika virus (ZIKV) seems to be prominently neurotropic, there are some reports of involvement of other organs, particularly the heart. Of special concern are those children exposed prenatally to ZIKV and born without microcephaly or other congenital anomalies. Electrocardiogram (ECG) - derived heart rate variability (HRV) metrics represent an attractive, low-cost, widely deployable tool for early identification of developmental functional alterations in exposed children born without such overt clinical symptoms.

Differences between the child and adult brain in the local functional structure of the cerebral cortex.

Neuroimage 2021 May 10:118150. Epub 2021 May 10.

ISGlobal, Barcelona, Spain; Pompeu Fabra University, Barcelona, Catalonia, Spain; Ciber on Epidemiology and Public Health (CIBERESP), Madrid, Spain.

Imaging studies on neuronal network formation provide relevant information as to how the brain matures during adolescence. We used a novel imaging approach combining well-established MRI measures of local functional connectivity that jointly provide qualitatively different information relating to the functional structure of the cerebral cortex. To investigate the adolescent transition into adulthood, we comparatively assessed 169 preadolescents aged 8-12 years and 121 healthy adults. Read More

Brief Report: Test-Retest Reliability of Cognitive, Affective, and Spontaneous Theory of Mind Tasks Among School-Aged Children with Autism Spectrum Disorder.

J Autism Dev Disord 2021 May 12. Epub 2021 May 12.

Laboratories of Cognitive Neuroscience, Boston Children's Hospital, Two Brookline Place, Brookline, MA, 02445, USA.

The present study evaluates the test-retest reliability of six theory of mind (ToM) tasks that measured cognitive, affective, and spontaneous ToM in 7 to 11 year-old children with autism spectrum disorder. Our results revealed considerable variation in test-retest reliability depending on the type of ToM task, which ranged from poor to good with the majority of the measures exhibiting moderate reliability. Results inform which common measures of cognitive ToM should be selected versus avoided in future intervention work, suggest our measure of spontaneous ToM should be used more widely in intervention and ToM research more broadly, and indicate more work is needed to develop reliable measures of affective ToM.

Knowing How to Fold 'em: Paper Folding across Early Childhood.

J Mot Learn Dev 2018 Jun;6(1):147-166

University of Wisconsin-Madison.

Folding paper is a seemingly simple act that requires planning, bimanual coordination, and manual strength and control to produce specific forces. Although paper folding has been used as an assessment tool and as a way to promote spatial skills, this study represents the first attempt to document when paper folding emerges across early childhood. Seventy-seven children (ages 18 months to 7 years) and an adult reference group (24 college-aged adults) completed three pre-specified folds on a single piece of paper. Read More

Front Psychol 2021 26;12:651725. Epub 2021 Apr 26.

Psycholinguistics, Faculty of Arts and Humanities, Paderborn University, Paderborn, Germany.

The economic principle of communication, according to which successful communication can be reached by least effort, has been studied for verbal communication. With respect to nonverbal behavior, it implies that forms of iconic gestures change over the course of communication and become reduced in the sense of less pronounced. These changes and their effects on learning are currently unexplored in relevant literature. Read More

Association between parents' socioeconomic conditions and nutritional status during childhood and the risk of cardiovascular disease in their adult offspring: an intergenerational study in south India.

J Epidemiol Community Health 2021 May 12. Epub 2021 May 12.

Department of Non-Communicable Disease Epidemiology, London School of Hygiene & Tropical Medicine, London, UK.

Background: Some researchers have suggested that parents' exposure to poor socioeconomic conditions during childhood can increase their offspring's risk of cardiovascular disease, primarily through poor maternal nutrition and growth. However, epidemiological data on this association are limited. In an intergenerational cohort from rural India, we examined the association of parental childhood socioeconomic conditions and stature with offspring's cardiovascular risk, hypothesising an inverse association between the two.

Prenatal Exposure And Child brain and mental Health (PEACH) study: protocol for a cohort study of children and youth with prenatal alcohol exposure.

BMJ Open 2021 May 11;11(5):e051660. Epub 2021 May 11.

Alberta Children's Hospital Research Institute, University of Calgary, Calgary, Alberta, Canada.

Introduction: Fetal alcohol spectrum disorder (FASD), which is caused by prenatal alcohol exposure (PAE), affects an estimated 4% of North Americans, and is the most common preventable cause of intellectual disability. Mental health problems, including anxiety and depression, are experienced by nearly all individuals with FASD. However, there is very limited knowledge about effective mental health treatments for individuals with FASD; effective treatments are hindered in part due to a lack of understanding of the basic neurobiology underlying internalising disorders in youth with FASD.

The Australian Child Maltreatment Study (ACMS): protocol for a national survey of the prevalence of child abuse and neglect, associated mental disorders and physical health problems, and burden of disease.

BMJ Open 2021 May 11;11(5):e047074. Epub 2021 May 11.

Graduate School of Education, University of Western Australia, Perth, Western Australia, Australia.

Introduction: Child maltreatment (physical abuse, sexual abuse, emotional abuse, neglect and exposure to domestic violence) is widely understood to be associated with multiple mental health disorders, physical health problems and health risk behaviours throughout life. However, Australia lacks fundamental evidence about the prevalence and characteristics of child maltreatment, its associations with mental disorders and physical health, and the associated burden of disease. These evidence gaps impede the development of public health strategies to better prevent and respond to child maltreatment. Read More
