The number of words children produce (expressive vocabulary) and understand (receptive vocabulary) changes rapidly during early development, partially due to genetic factors. Here, we performed a meta-genome-wide association study of vocabulary acquisition and investigated polygenic overlap with literacy, cognition, developmental phenotypes, and neurodevelopmental conditions, including attention-deficit/hyperactivity disorder.
In multi-cohort consortia, the problem often arises that a phenotype is measured using different questionnaires. This study aimed to harmonize scores based on the Child Behaviour Check List (CBCL) and the Strength and Difficulties Questionnaire (SDQ) for anxiety/depression and ADHD.
Iron deficiency may play a role in the pathophysiology of Attention Deficit/Hyperactivity Disorder (ADHD). Due to its preponderant function in monoamine catecholamine and myelin synthesis, brain iron concentration may be of primary interest in the investigation of iron dysregulation in ADHD.
Parents of children with attention-deficit/hyperactivity disorder (ADHD) often make disclosure decisions about their child's ADHD on their behalf. While disclosure can facilitate access to support, it risks stigma. Despite ADHD being one of the most common neurodevelopmental conditions, little is known about parent's experiences in relating information about their child's ADHD diagnosis or medication use, to others.
Harmonizing the scores obtained by different instruments that measure the same construct enable researchers to combine them in one analysis. An important step in harmonization is checking whether there is measurement invariance across populations.
To examine the lived experiences of young people successfully managing life with ADHD and investigate the applicability of adult models of Recovery to these individuals.
Autism and attention-deficit/hyperactivity disorder (ADHD) often co-occur. This survey of 288 New Zealand parents of children diagnosed with autism, ADHD, or both conditions, examined the relations between age of diagnosis and early atypical development, the age specialist consultation was needed and types of specialists seen.
Little is known about parent preferences regarding delivery methods of early interventions. This research examined, through parent report, the current and preferred delivery methods of seven common educational early interventions accessed by New Zealand children with autism spectrum disorder.
Children with ADHD are disadvantaged from an early age in key areas of learning, and this risk increased with reduction in gestational age at birth
This study examined whether the 12-month prevalence of major depressive disorder, attention-deficit/hyperactivity disorder, and conduct disorder among 6- to 17-year-olds in Australia changed between 1998 and 2013 to 2014. It also investigated whether changes in the prevalence of disorders over this time varied for children living in families containing 2 parents versus single parents, and families with high versus low income.
