Schizophrenia is a devastating neuropsychiatric syndrome associated with distributed brain dysconnectivity that may involve large-scale thalamo-cortical systems. Incomplete characterization of thalamic connectivity in schizophrenia limits our understanding of its relationship to symptoms and to diagnoses with shared clinical presentation, such as bipolar illness, which may exist on a spectrum. Using resting-state functional magnetic resonance imaging, we characterized thalamic connectivity in 90 schizophrenia patients versus 90 matched controls via: (1) Subject-specific anatomically defined thalamic seeds; (2) anatomical and data-driven clustering to assay within-thalamus dysconnectivity; and (3) machine learning to classify diagnostic membership via thalamic connectivity for schizophrenia and for 47 bipolar …

Factors Affecting Attitudes Towards Individuals With Schizophrenia: Perceptions Of Mexican American College Students, Valerie Paredes

Theses and Dissertations - UTB/UTPA

This study is designed to examine the effects of acculturation and level of familiarity on stigma of Mexican American college students towards individuals with schizophrenia along the border of Texas and Mexico (N = 223). The area has a history of high levels of disparity in regards to the utilization of mental health services. Data was collected by surveying Mexican American college students through a convenience sample at two separate post-secondary southwestern Hispanic-Serving Institutions (HSIs) along a border community. The instrumentation for the study was composed of a demographic questionnaire, The Acculturation Scale for Mexican-Americans-II (Cuéllar, Arnold, & Maldonado, 1995), …

Biological Basis For Cerebral Dysfunction In Schizophrenia In Contrast With Alzheimer’S Disease, Rodrigo O. Kuljis, Luis V. Colom, Leonel E. Rojo

Schizophrenia and Alzheimer’s disease are two disorders that, while conceptualized as pathophysiologically and clinically distinct, cause substantial cognitive and behavioral impairment worldwide, and target apparently similar – or nearby – circuitry in regions such as the temporal and frontal lobes.We review the salient differences and similarities from selected historical, nosological, and putative mechanistic viewpoints, as a means to help both clinicians and researchers gain a better insight into these intriguing disorders, for which over a century of research and decades of translational development was needed to begin yielding treatments that are objectively effective, but still very far from entirely satisfactory. …

Pd_Ngsatlas: A Reference Database Combining Next-Generation Sequencing Epigenomic And Transcriptomic Data For Psychiatric Disorders, Zheng Zhao, Yongsheng Li, Hong Chen, Jianping Lu, Peter M. Thompson, Juan Cheng, Zishan Wang, Juan Xu, Chun Xu, Xia Li

Background: Psychiatric disorders such as schizophrenia (SZ) and bipolar disorder (BP) are projected to lead the global disease burden within the next decade. Several lines of evidence suggest that epigenetic- or genetic-mediated dysfunction is frequently present in these disorders. To date, the inheritance patterns have been complicated by the problem of integrating epigenomic and transcriptomic factors that have yet to be elucidated. Therefore, there is a need to build a comprehensive database for storing epigenomic and transcriptomic data relating to psychiatric disorders.

Description: We have developed the PD_NGSAtlas, which focuses on the efficient storage of epigenomic and transcriptomic data based …
