Complement system is one of the most important defense mechanisms of the innate immune system. In addition to their roles in immune regulation, complement proteins are also involved in neurodevelopment and adult brain plasticity. Complement dysregulation has been shown in neurodevelopmental disorders including schizophrenia and autism spectrum disorder as well as in mood disorders. A number of clinical as well as genetic studies suggest the role of complement proteins in the cortical thinning and excessive synaptic pruning frequently associated with schizophrenia. The changes in complement proteins are also associated with the pathophysiology of autism spectrum disorder, major depressive disorder and …

BACKGROUND AND HYPOTHESIS: Schizophrenia (SZ) and bipolar disorder (BD) share genetic risk factors, yet patients display differential levels of cognitive impairment. We hypothesized a genome-transcriptome-functional connectivity (frontoparietal)-cognition pathway linked to SZ-versus-BD differences, and conducted a multiscale study to delineate this pathway.

STUDY DESIGNS: Large genome-wide studies provided single nucleotide polymorphisms (SNPs) conferring more risk for SZ than BD, and we identified their regulated genes, namely SZ-biased SNPs and genes. We then (a) computed the polygenic risk score for SZ (PRSSZ) of SZ-biased SNPs and examined its associations with imaging-based frontoparietal functional connectivity (FC) and cognitive performances; (b) examined the spatial …

Background:

While functional connectivity is widely studied, there has been little work studying functional connectivity at different spatial scales. Likewise, the relationship of functional connectivity between spatial scales is unknown.

Methods:

We proposed an independent component analysis (ICA)-based approach to capture information at multiple-model orders (component numbers), and to evaluate functional network connectivity (FNC) both within and between model orders. We evaluated the approach by studying group differences in the context of a study of resting-state functional magnetic resonance imaging (rsfMRI) data collected from schizophrenia (SZ) individuals and healthy controls (HC). The predictive ability of FNC at multiple spatial scales …


A Life Lived With Schizophrenia: When Mother’S Love Is Kept In The Dark Exploring Maternal Communication And Attachment Organization In Families With Schizophrenia, Myrsini Stefanidou Marini May 2022

A Life Lived With Schizophrenia: When Mother’S Love Is Kept In The Dark Exploring Maternal Communication And Attachment Organization In Families With Schizophrenia, Myrsini Stefanidou Marini

Electronic Theses and Dissertations

In recent years, research into the transgenerational transmission of attachment styles has shown that a mother’sattachment style often predicts the attachment style of her infant. Fearsome parental behavior has been found to predict disorganized attachment in infants, which is further associated with a range of mental health disturbances in adolescence. Furthermore, regular patterns of disturbed communication between mother and child have also been found to lead to ‘schizophrenic’ thinking and behavior in the child’s life. While acknowledging that genetic and other biological factors contribute to the emergence of schizophrenia, this study focused on disorganized attachment and disturbed communication between mother …
