Altered Network Organization And Screen Time Use In Childhood Attention-Deficit / Hyperactivity Disorder (Adhd), Elizabeth Jane Hawkey
Altered Network Organization And Screen Time Use In Childhood Attention-Deficit / Hyperactivity Disorder (Adhd), Elizabeth Jane Hawkey
Arts & Sciences Electronic Theses and Dissertations
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) …
Picky Eating In Children: Associations With Iq And Executive Functioning, Ara Nazmiyal
Picky Eating In Children: Associations With Iq And Executive Functioning, Ara Nazmiyal
Senior Honors Papers / Undergraduate Theses
Picky eating is an under-researched behavior in children. The current study aims to assess what behaviors correlate with picky eating to better understand potential risk factors for Anorexia Nervosa. 111 children were evaluated at 5 and 6 years old, and a subset was evaluated again at 7 and 8 years old (n=36). Executive function and IQ were evaluated using parent reports and behavioral measures at baseline. Picky eating was reported by a parent questionnaire. Results showed deficits in shifting to be a predictor of higher picky eating behaviors at ages 5-6 years. Additionally, children who were reported extremely picky eaters …
Blood Phenylalanine Trajectory And Executive Function Outcomes In Individuals With Phenylketonuria, Clarissa Tardiff
Blood Phenylalanine Trajectory And Executive Function Outcomes In Individuals With Phenylketonuria, Clarissa Tardiff
Arts & Sciences Electronic Theses and Dissertations
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., …
Prospective Memory Impairment In Parkinson Disease Without Dementia: Cognitive Mechanisms And Intervention, Erin R. Foster
Prospective Memory Impairment In Parkinson Disease Without Dementia: Cognitive Mechanisms And Intervention, Erin R. Foster
Arts & Sciences Electronic Theses and Dissertations
Cognitive impairment among non-demented individuals with Parkinson disease (PD) produces significant disability, reduced quality of life, and restricted participation. This dissertation will cover PD-related impairment in prospective memory, or the ability to remember to execute delayed intentions at the appropriate moment in the future. Prospective memory impairment in PD is increasingly recognized as a functionally and clinically relevant problem and viable target for cognitive intervention. To lay the groundwork for the development of effective interventions for prospective memory in PD, this dissertation examines the cognitive mechanisms underlying prospective memory impairment in PD and the potential of training in a targeted …
