Developmental Trajectories of the Corpus Callosum in Attention-Deficit/Hyperactivity Disorder

TL;DR: Right-handed participants with ADHD showed a significantly higher rate of growth in the anterior-most region of the corpus callosum than their typically developing peers, documents the dynamic, age-dependent nature of callosal and congruent prefrontal cortical abnormalities characterizing ADHD.
Journal ArticleDOI

Hormonal correlates of clozapine-induced weight gain in psychotic children: an exploratory study.

TL;DR: Hormonal changes are correlated with weight gain in patients with childhood-onset schizophrenia on clozapine, and body mass index increase was significantly correlated with decrease in ghrelin and adiponectin and was positively correlated with clinical improvement.
Journal ArticleDOI

Everyday executive functions in Down syndrome from early childhood to young adulthood: evidence for both unique and shared characteristics compared to youth with sex chromosome trisomy (XXX and XXY)

TL;DR: These findings will be discussed within the context of efforts to identify syndrome specific cognitive-behavioral profiles for youth with different genetic syndromes in order to inform basic science investigations into the etiology of EF difficulties in these groups and to develop treatment approaches that are tailored to the needs of these groups.
Journal ArticleDOI

Common functional polymorphisms of DISC1 and cortical maturation in typically developing children and adolescents

TL;DR: This work related genotype at Leu607Phe and Ser704Cys to cortical thickness (CT) in 255 typically developing individuals aged 9–22 years on whom 598 magnetic resonance imaging brain scans had been acquired longitudinally to suggest that these SNPs might operate to shape risk for diverse phenotypes by impacting on the early maturation of fronto-temporal cortices.
Journal ArticleDOI

Influences of Brain Size, Sex, and Sex Chromosome Complement on the Architecture of Human Cortical Folding.

TL;DR: This work uses structural neuroimaging to measure a global sulcation index (SI), brain size‐independent sulcal lengthening in males versus females, and insensitivity of overall folding architecture to SCD, and provides a novel context for future studies of human cortical folding in health and disease.
