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.
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.
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.
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.
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.
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.
Approximately 8% of all children experience developmental and mental health conditions. Similarities in characteristics across neurodevelopmental conditions-such as difficulties in communication and language, social interaction, motor coordination, attention, activity regulation, behavior, mood, and sleep-make it challenging to attribute these characteristics exclusively to specific diagnoses and assessments. The purpose of this study was to identify symptomatic domains across neurodevelopmental conditions in children and to explore dimension reduction for transdiagnostic assessment.
