Attention-Deficit/Hyperactivity Disorder (ADHD)/Hyperkinetic Disorder (HD) is linked to increased risks of morbidity, comorbidity and mortality, with higher prevalence in clinical populations. The differential prevalence of ADHD/HD across adult and pediatric clinical populations, influenced by factors such as time trends, sex, age, geographic regions, and comorbidities, has not been systematically assessed.
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.
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.
The Kids is trialling a new tool for earlier and easier screening of FASD and ADHD in children, using cutting-edge eye-tracking technology developed by the Kids Brain Health Network in Canada.
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.
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.
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.
ADHD commonly occurs with sleep problems and secondary cognitive impairments such as inhibitory control. Sleep problems may explain attentional lapses and inhibition performance variability in children with ADHD. This study applied Bayesian analyses to examine the relationship between ADHD symptoms, sleep problems, and inhibition.
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.
