Genome-wide association meta-analysis of childhood ADHD symptoms and diagnosis identifies new loci and potential effector genesWe 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.

Brain iron concentration in childhood ADHD: A systematic review of neuroimaging studiesIron 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.

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

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.

Enabling successful life engagement in young people with ADHD: new components beyond adult models of recoveryTo 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 ADHDAutism 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 PerformanceADHD 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.

Prevalence of attention deficit hyperactivity disorder/hyperkinetic disorder of pediatric and adult populations in clinical settings: a systematic review, meta-analysis and meta-regressionAttention-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.

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