Abstract In the literature, there are substantial machine learning attempts to classify schizophrenia based on alterations in resting-state (RS) brain patterns using functional magnetic resonance imaging (fMRI). Most earlier studies modelled patients undergoing treatment, entailing confounding with drug effects activity, and making them less applicable real-world diagnosis at point of first medical contact. Further, most classification accuracies >80% small sample datasets, which may be...

Abstract Current knowledge about functional connectivity in obsessive-compulsive disorder (OCD) is based on small-scale studies, limiting the generalizability of results. Moreover, majority studies have focused only predefined regions or networks rather than throughout entire brain. Here, we investigated differences resting-state between OCD patients and healthy controls (HC) using mega-analysis data from 1024 1028 HC 28 independent samples ENIGMA-OCD consortium. We assessed group...

Background Various lines of evidence including epidemiological, genetic and foetal pathogenetic models suggest a compelling role for Interleukin-6 (IL-6) in the pathogenesis schizophrenia. IL-6 mediated inflammatory response triggered by maternal infection or stress induces disruption prenatal hippocampal development which might contribute towards psychopathology during adulthood. There is substantial lack knowledge on how predisposition to elevated expression effects structure schizophrenia...

Context: The neurobiological effect of yoga on the cortical structures in elderly is as yet unknown. Materials and Methods: Seven healthy subjects received intervention an add-on life-style practice. Magnetic resonance imaging scans were obtained before 6 months later. Voxel-based-morphometric analyses compared brains after yoga. Results: Yoga group was found to have increases hippocampal, but not occipital gray matter. Conclusion: has potential reduce neuro-senescence. Small sample size...

Background and Purpose Emerging studies have shown that gut-derived endotoxins might play a role in intestinal systemic inflammation. Although the significance of permeability modulating pathogenesis Schizophrenia (SCZ) is recognized, not much data on specific biomarkers, viz., zonulin, lipopolysaccharide-binding protein (LBP), alkaline phosphatase (IAP) SCZ available. Therefore, we measured plasma levels LBP, IAP its correlation with neutrophil-to-lymphocyte ratio (NLR); marker inflammation...

White matter pathways, typically studied with diffusion tensor imaging (DTI), have been implicated in the neurobiology of obsessive-compulsive disorder (OCD). However, due to limited sample sizes and predominance single-site studies, generalizability OCD classification based on white estimates remains unclear. Here, we tested accuracy using largest DTI dataset date, involving 1336 adult participants (690 patients 646 healthy controls) 317 pediatric (175 142 from 18 international sites within...
