Testing Candidate Cerebellar Presymptomatic Biomarkers For Autism Spectrum Disorder, Zoe Wilson Hawks
Testing Candidate Cerebellar Presymptomatic Biomarkers For Autism Spectrum Disorder, Zoe Wilson Hawks
Arts & Sciences Electronic Theses and Dissertations
Background: Autism spectrum disorder (ASD) is a neurodevelopmental disorder diagnosed on the basis of social impairment, restricted interests, and repetitive behaviors. Contemporary theories posit that cerebellar-mediated error signaling impairments contribute to the causation of ASD. However, the relationship between infant cerebellar functional connectivity (fcMRI) and later ASD behaviors and outcomes has not been investigated. Such work is critical to establish early (presymptomatic) cerebellar correlates of ASD. Methods: Data from the Infant Brain Imaging Study (n=94, 68 male) were used to evaluate cerebellar fcMRI as a presymptomatic biomarker for ASD. Specifically, brain-behavior associations were analyzed for 6-month cerebellar connections in relation …
Parental Psychological Distress After Prenatal Diagnosis Of Congenital Heart Disease: Patterns, Predictors, And Impact On Early Outcomes., Kathryn Mangin-Heimos
Parental Psychological Distress After Prenatal Diagnosis Of Congenital Heart Disease: Patterns, Predictors, And Impact On Early Outcomes., Kathryn Mangin-Heimos
Arts & Sciences Electronic Theses and Dissertations
Congenital heart disease (CHD) is the most common birth defect and is often diagnosed during pregnancy. The transition to parenthood after prenatal diagnosis can be particularly challenging. Both mothers and fathers are at elevated risk for psychological distress, yet early distress frequencies and patterns have not been well characterized. The impact of psychological distress on parents’ perceptions of their readiness to care for their infant after hospital discharge is currently unknown. The association of psychological distress with early infant neurodevelopment has also been under investigated. To examine these gaps in knowledge, we conducted a single center, prospective cohort study of …
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 …
Refining The Characterization Of Causation In Early Childhood Neuropsychiatric Conditions: Nature, Nurture, And Time, Rachael Elizabeth Wagner
Refining The Characterization Of Causation In Early Childhood Neuropsychiatric Conditions: Nature, Nurture, And Time, Rachael Elizabeth Wagner
Arts & Sciences Electronic Theses and Dissertations
Understanding causal factors in the development of early childhood neuropsychiatric conditions is essential for an understanding of disease mechanisms and therapeutic approaches. Yet the lack of objective classification of psychiatric diagnoses, phenotypic and genetic heterogeneity, pleiotropy, and extensive comorbidity have posed immense challenges to the acquisition of knowledge regarding neuropsychiatric disease etiology. While it is unequivocally established that nearly all psychiatric conditions are substantially heritable, non-genetic factors do play a role in the development of psychopathology. This thesis explores both genetic and environmental contributors to neuropsychiatric conditions in an attempt to refine the characterization of some of these risk factors. …
