Structural and Functional Connectivity of Visual Cortex in Schizophrenia and Bipolar Disorder: A Graph-Theoretic Analysis

Abstract: Visual processing abnormalities in schizophrenia (SZ) are poorly understood, yet predict functional outcomes in the disorder. Bipolar disorder (BD) may involve similar visual processing deficits. Converging evidence suggests that visual processing may be relatively normal at early stages of visual processing such as early visual cortex (EVC) but that processing abnormalities may become more pronounced by mid-level visual areas such as lateral occipital cortex (LO). However, little is known about the connectivi… Show more

“…For the BP disease, secondary visual cortex and medial to superior temporal gyrus are selected as salient ROIs. This observation is in line with existing studies that visual processing abnormalities have been characterized in bipolar disorder patients [28,30], which is also confirmed in Fig. 2(c)(d).…”

“…Overall, our work supports the hypothesis that BD may be associated with impaired visual processing (Reavis et al, 2020) and provides evidence of structural abnormalities of the visual system in BD-I similar to other disorders of the psychosis spectrum (Reavis et al, 2020). Furthermore, the association between structural changes and impairments in cognitive and social-cognitive domains may contribute to functional deficits and clinical outcomes in BD-I.…”

“…For example, BD patients spend the majority of their lives suffering from depression, and they are frequently misdiagnosed as UD (Phillips & Kupfer, 2013 ; Rai et al, 2021 ). Identifying robust and reliable neural biomarkers for BD is a promising approach for better understanding the underlying neurobiology and improving patient treatment outcomes (Ching et al, 2022 ; Reavis et al, 2020 ).…”
