Harmonization of SDQ and ASEBA Phenotypes: Measurement Variance Across Cohorts

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.

Investigation of associations between self-reported sensory processing, eating disorder symptoms, neurodivergence, and gender congruence from a lived experience lens

Eating disorders (EDs) are increasingly recognised among neurodivergent and transgender and gender diverse (TGD) individuals, yet most assessment and treatment models remain grounded in cisnormative and neuronormative assumptions and frameworks. Sensory processing, spanning interoception and exteroception, has been proposed as a potential factor that may help explain observed associations between neurodivergent traits, gender incongruence, and EDs. 

Effect of methylphenidate exposure on glutamate and glutamate-related metabolites in patients with ADHD: a systematic review

Dysfunctional glutamatergic neurotransmission has been implicated in the underlying pathogenesis of Attention Deficit Hyperactivity Disorder (ADHD). The psychostimulant methylphenidate (MPH), which is used as a first line treatment for ADHD, has been shown to have both acute and chronic effects on prefrontal cortex glutamatergic afferents. Animal studies have also identified an effect of MPH and glutamate in prefrontal areas. Despite this there are ongoing questions as to the extent and direction of this effect, as well as its impact on other neurobiological processes. 

Genome-Wide Analyses of Vocabulary Size in Infancy and Toddlerhood: Associations With Attention-Deficit/Hyperactivity Disorder, Literacy, and Cognition-Related Traits

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. 

Harmonized Phenotypes for Anxiety, Depression, and Attention-Deficit Hyperactivity Disorder (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.

Use of Neuroimaging to Predict Adverse Developmental Outcomes in High-Risk Infants

With advances in perinatal care, we have achieved major reductions in mortality in premature and critically ill infants, but they still remain at increased risk of neurodevelopmental disability. In this context, recent advances in neuroimaging are perceived as an addition of significant value to current clinical developmental screening programs.

Enabling successful life engagement in young people with ADHD: new components beyond adult models of recovery

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.

Parent-reported Early Atypical Development and Age of Diagnosis for Children with Co-occurring Autism and ADHD

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.

The Role of Sleep in the Relationship Between ADHD Symptoms and Stop Signal Task Performance

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.

Early Intervention Delivery Methods for New Zealand Children with Autism: Current Practices Versus Parental Preferences

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.
