J Atten Disord 2021 Jun 4:10870547211020087. Epub 2021 Jun 4.

University of North Carolina at Asheville, USA.

Objective: To Explore whether subtypes and comorbidities of attention-deficit hyperactivity disorder (ADHD) induce distinct biases in cognitive components involved in information processing.

Method: Performance on the Integrated Visual and Auditory Continuous Performance Test (IVA-CPT) was compared between 150 children (aged 7 to 10) with ADHD, grouped by DSM-5 presentation (ADHD-C, ADHD-I) or co-morbid diagnoses (anxiety, oppositional defiant disorder [ODD], both, neither), and 60 children without ADHD. Diffusion decision modeling decomposed performance into cognitive components. Read More

Child Neuropsychol 2021 Apr 30:1-30. Epub 2021 Apr 30.

Department of Clinical Psychology and Psychobiology, Faculty of Psychology, University of Barcelona, Barcelona, Spain.

This study aimed to compare performance in working memory (WM), processing speed (PRS), and attention measures in children and adolescents with typical development (TD) and with Attention deficit hyperactivity disorder (inattentive [ADHD-I] or combined [ADHD-C]) presentations, and to determine the predictive ability of the measures mentioned to discriminate between ADHD presentations and TD. 260 children and adolescents, 138 with ADHD (70 ADHD-I and 68 ADHD-C) and 122 TD in two age cohorts (8-12 years; 13-16 years), were assessed with WM and PRS indexes of Wechsler Intelligence Scale for Children (WISC-IV) and the d2 attention test.

Asymmetry in Cortical and Subcortical Structures of the Brain in Children and Adolescents with Attention-Deficit/Hyperactivity Disorder.

Neuropsychiatr Dis Treat 2021 12;17:493-502. Epub 2021 Feb 12.

The National Clinical Research Center for Mental Disorders & Beijing Key Laboratory of Mental Disorders, Beijing Anding Hospital, Capital Medical University, Beijing, 100088, People's Republic of China.

Background: Human cognitive and emotional functions are asymmetrical between the left and right hemispheres. In neuroimaging studies of attention-deficit/hyperactivity disorder (ADHD) patients, the absence of aberrant asymmetry might serve as a neuroanatomical marker of ADHD. However, few studies have estimated abnormalities in cortical and subcortical asymmetry in children and adolescents of different ADHD subtypes. Read More

Effects of the dopamine transporter gene on neuroimaging findings in different attention deficit hyperactivity disorder presentations.

Brain Imaging Behav 2021 Apr 20;15(2):1103-1114. Epub 2021 Jan 20.

Department of Child and Adolescent Psychiatry, Faculty of Medicine, Ege University, Izmir, Turkey.

Attention-Deficit/Hyperactivity Disorder (ADHD) is a phenotipically and neurobiologically heterogeneous disorder. Deficiencies at different levels in response inhibition, differences in dopamine transporter genotype (DAT1) and various symptomatic presentations contribute to ADHD heterogeneity. Integrating these three aspects into a functional neuroimaging research could help unreval specific neurobiological components of more phenotipically homogeneous groups of patients with ADHD.

Eur Child Adolesc Psychiatry 2020 Oct 15. Epub 2020 Oct 15.

Department of Nutrition, Food Science, and Gastronomy, University of Barcelona, Av. Prat de la Riba 171. Recinte Torribera. Edifici Verdaguer, Santa Coloma de Gramenet, 08921, Barcelona, Spain.

Symptom Level Associations Between Attention-Deficit Hyperactivity Disorder and School Performance.

Clin Pediatr (Phila) 2020 09 22;59(9-10):874-884. Epub 2020 May 22.

Vermont Department of Health, Burlington, VT, USA.

Attention-deficit hyperactivity disorder (ADHD) is associated with reduced school performance. To determine which ADHD symptoms and subtypes have the strongest association, we used type and frequency of symptoms on the 2014 National Survey of the Diagnosis and Treatment of ADHD and Tourette Syndrome (NS-DATA) to create symptom scores for inattention and hyperactivity-impulsivity and define subtypes (ADHD-Inattentive [ADHD-I], ADHD-Hyperactive-Impulsive, ADHD-Combined [ADHD-C]). Regression methods were used to examine associations between symptoms and subtype and a composite measure of school performance. Read More

Does behavioural inhibition system dysfunction contribute to Attention Deficit Hyperactivity Disorder?

Personal Neurosci 2019 8;2:e5. Epub 2019 Aug 8.

Department Psychology, University of Otago, POB 56, Dunedin, New Zealand.

The Reinforcement Sensitivity Theory of Personality has as its main foundation a Behavioural Inhibition System (BIS), defined by anxiolytic drugs, in which high trait sensitivity should lead to internalising, anxiety, disorders. Conversely, it has been suggested that low BIS sensitivity would be a characteristic of externalising disorders. BIS output should lead to increased arousal and attention as well as behavioural inhibition. Read More

Comparing directed functional connectivity between groups with confirmatory subgrouping GIMME.

Neuroimage 2019 03 21;188:642-653. Epub 2018 Dec 21.

Department of Psychology and Neuroscience, University of North Carolina at Chapel Hill, Chapel Hill, NC, USA.

Connectivity modeling in functional neuroimaging has become widely used method of analysis for understanding functional architecture. One method for deriving directed connectivity models is Group Iterative Multiple Model Estimation (GIMME; Gates and Molenaar, 2012). GIMME looks for commonalities across the sample to detect signal from noise and arrive at edges that exist across the majority in the group ("group-level edges") and individual-level edges.
