The meta-analysis included 39 studies, encompassing 63,444 patients with CVD, 12,308 of whom were diagnosed with depression. The results revealed a significant association between CVD and depression or anxiety, with an estimated overall prevalence of depression in CVD patients of 20.8%. Subgroup analyses showed that the prevalence of depression in patients with coronary artery disease and heart failure was 19.8 and 24.7%, respectively. According to a random-effects model, depressive symptoms were linked to an increase in unadjusted all-cause mortality compared with non-depressed patients. The MR analysis, employing the inverse-variance weighted method as the primary tool for causality assessment, identified significant associations between various CVD types and depression or anxiety phenotypes. These findings underscore the significant relationship between CVD and depression or anxiety, leading to an elevated risk of all-cause mortality. Moreover, the MR analysis provides the first genetically-informed evidence suggesting that depression plays a critical role in the development and progression of certain CVD subtypes.

GAEA and disorder-specific family genetic risk score (FGRS) were calculated from extended pedigrees. In males, information on IQ and resilience was obtained from the Swedish conscript registry. Affected individuals were born in Sweden from 1973–1995 to Swedish born parents. Controlling for disorder specific FGRS, GAEA were negatively and substantially associated with risk for externalizing and internalizing disorders, minimally associated with psychotic disorder risk and positively and modestly associated with risk for eating/compulsive disorders. While the majority of GAEA effect on risk for externalizing disorders was mediated through impact on IQ, for internalizing disorders, mediation was largely through resilience. For externalizing and internalizing disorders, interactions between GAEA and disorder specific FGRS were robust and negative – the slope of disorder risk with increasing genetic liability was steepest in those with low GAEA. For eating disorders, interactions were modest and positive –the slope of risk with increasing genetic liability being steepest in individuals with high GAEA. We found that the impact of GAEA on risk for psychiatric and substance can be substantial and varies widely across disorders in magnitude, direction, and mediation.

Though the mechanisms of this heterogeneity remain unclear, the characterization of bioactive tau species and factors that regulate their seeding behavior might give valuable insight as pathological tau is well correlated with cognitive impairment. Here, we conducted an innovative investigation into the molecular basis of widespread, connectivity-based tau propagation that begins in the inferior temporal gyrus (ITG) and spreads to neocortical areas such as the prefrontal cortex (PFC). Biochemical analysis of human postmortem ITG and PFC tissues revealed individual variability in tau seeding, which correlated with cognitive decline, particularly in the ITG, a region known for promoting accelerated tau propagation. Notably, this study presents the first evidence that site-specific phosphorylation and isoform composition of both aggregation-prone high-molecular-weight (HMW) tau and the relatively unexplored, yet potentially crucial in AD progression low-molecular-weight (LMW) tau significantly contribute to tau propagation and cognitive decline. Our findings underscore the importance of comprehensively considering diverse tau forms including both HMW and LMW tau species in understanding AD progression. Additionally, these results are the first to identify distinct morphological strains within the AD brain associated with differing seeding propensity, potentially enabling patient stratification based on their tau profile. Furthermore, RNA-seq analyses of gene expression patterns in the ITG revealed molecular heterogeneity associated with tau seeding potential. Patients with higher levels of seed-competent tau displayed greater impairments in synaptic and neural plasticity, and increased neuroinflammation. This multidisciplinary study offers novel insights into various molecular mechanisms driving AD progression, suggesting potential molecular targets for early intervention and improved patient subtyping, which is critical for developing precision medicine approaches.</p>","PeriodicalId":19008,"journal":{"name":"Molecular Psychiatry","volume":"6 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143836920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review explores the neurobiology underlying SUDs, emphasizing the roles of the prefrontal cortex, striatal circuits, and dopaminergic pathways, and examines the theory that TMS modulates neurocircuitry to impact addiction-related behaviors. We discuss TMS procedural aspects and provide a comparative analysis of TMS protocols, focusing on repetitive, deep, single-pulse, paired-pulse, and a more recent approach, theta burst stimulation. We review recent randomized clinical trials (RCTs) to demonstrate reductions in cravings and use across SUDs as well as highlight the need for standardized protocols. We emphasize the power of combining neuroimaging techniques to show functional connectivity changes in the brain and identify potential biomarkers predictive of SUD treatment response, an unexplored area of discussion. With these topics, this review highlights the potential of TMS as a versatile and effective therapeutic modality for SUDs, especially when combined with neuroimaging. Key findings emphasize the necessity for future research to address methodological challenges, such as standardizing protocols and optimizing stimulation parameters. The integration of neuroimaging provides insights into functional connectivity changes, enabling enhanced precision and individualized treatment strategies.
