Introduction: Symptoms of attention-deficit/hyperactivity disorder (ADHD) have been associated with alterations in functional connectivity involving networks in the developing brain that support optimal cognitive control. However, a clear profile of altered connectivity has yet to emerge, and it remains unclear whether changes in behavioral patterns such as screen time (ST) contribute to ADHD symptomatology and altered connectivity in networks that support cognitive control. The current study examined connectivity between large-scale networks associated with cognitive control (CC), measures of executive function (EF) which index CC, and ST in children with ADHD. Methods: Our sample included 11,874 children (ages 9-11, 52% male) …

Phenylketonuria (PKU) is an autosomal recessive disorder characterized by mutations in phenylalanine hydroxylase genes. As a result, phenylalanine (Phe) metabolism is disrupted, and this amino acid accumulates in blood and tissue (Pietz, 1998; Scriver et al., 2000). Although the most severe symptoms of PKU may be avoided by early detection and treatment, many individuals with early-treated PKU still experience difficulties in executive function, attention, and processing speed (Antenor-Dorsey et al., 2013; Araujo et al., 2013; Christ et al., 2020; Hawks, Strube, Johnson, Grange, & White, 2018; Hood, Grange, Christ, Steiner, & White, 2014; Janos et al., 2012; White et al., …
