ADHD has been associated with impaired central nervous dopaminergic pathways. Brain iron is an essential cofactor for the synthesis of dopamine and the substantia nigra (SN) is a significant pool of dopaminergic neurons playing a central role in the activity of the nigrostriatal pathway. The present study investigated SN iron content in children with ADHD, its relationship with ADHD symptom severity and cognitive performance.
We performed a genome-wide association meta-analysis of 290,134 attention-deficit/hyperactivity disorder symptom measures of 70,953 unique individuals from multiple raters, ages and instruments.
Social media allows users to connect with others’ experiences and points of view, with TikTok being the fastest-growing platform worldwide. Highly viewed videos related to neurodiversity on TikTok have an increasing role in understanding and acceptance of neurodivergent individuals.
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 explored the lived experience of university students with attention-deficit hyperactivity disorder (ADHD) and identified factors that help or hinder their capacity for self-compassion in higher education. Fourteen university students with ADHD aged 18–25 participated in individual semi-structured interviews exploring experiences of self-compassion in academic contexts.
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.
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.
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.
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.
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.
