While participants were passively watching faces approaching them in contrast to static faces, group comparison revealed that patients with high paranoia showed hypoactivity mainly in the OFC when compared to patients with low paranoia, and hypoactivity in dlPFC and dPCC when compared to controls. Further, paranoia severity was positively associated with activation of the right hippocampus. Altered neural activity in the OFC, dlPFC, and hippocampus may well reflect the neural responses to the paranoid experience of threat and provide evidence for the hypothesized association between limbic dysfunction and paranoid threat.

The study sample consisted of 277 patients from the Treatment and Early Intervention in Psychosis Program (TIPP) at Lausanne University Hospital. Symptom severity was assessed using the Positive and Negative Syndrome Scale (PANSS), functioning was evaluated with an adapted version of the general subscale of the Premorbid Adjustment Scale (PAS), and the five most common CT experiences (sexual, physical and emotional abuse; physical and emotional neglect) was measured using a tailored questionnaire. Data from early assessments (2 and 6 months after admission) were used for analysis. A network model was fitted to estimate the shortest pathways linking different types of CT to various domains of functioning. Our findings revealed two distinct pathways connecting CT to functioning. One pathway influenced occupational functioning through sexual abuse and depression, while another pathway affected socio-personal functioning through physical neglect and stereotyped thinking.

Additionally, some trials have suggested that vitamin E may benefit TD patients. However, the mechanistic basis for these treatments remains unclear. The objective of this study was to analyze and compare the mechanisms of valbenazine, deutetrabenazine, and vitamin E in TD treatment utilizing network pharmacology and molecular docking approaches. Putative target genes associated with valbenazine, deutetrabenazine, and vitamin E were retrieved from the PharmMapper, CTD, GeneCards, SwissTargetPrediction, and DrugBank databases. TD-related targets were identified using the GeneCards, DisGeNET, OMIM, and TTD databases. A protein-protein interaction (PPI) network was created to identify core targets. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were conducted via DAVID, and Cytoscape was used to build a drug-pathway-target-disease network. Molecular docking evaluated drug-target interactions. A total of 32, 36, and 62 targets relevant to the treatment of TD were identified for valbenazine, deutetrabenazine, and vitamin E, respectively. PPI and KEGG pathway analyses suggested that valbenazine and deutetrabenazine may influence TD through the dopaminergic synapse signaling pathway via common core targets (e.g., Dopamine Receptor D1 (DRD1), DRD2, Monoamine Oxidase B (MAOB), Solute Carrier Family 6 Member 3 (SLC6A3), SLC18A2) and specific targets (DRD3 for valbenazine, MAOA for deutetrabenazine). Vitamin E may affect TD by targeting the PI3K-Akt pathway through AKT Serine/Threonine Kinase 1 (AKT1), Brain-Derived Neurotrophic Factor (BDNF), Insulin (INS), Nitric Oxide Synthase 3 (NOS3), and Toll-Like Receptor 4 (TLR4). This study provides insights into the common and unique molecular mechanisms by which valbenazine, deutetrabenazine, and vitamin E may treat TD.
