Abstract

Personality changes are a clinical criterion for dementia diagnosis, yet their progression across disease stages remains unclear. This systematic review and meta-analyses examined change in the five major personality traits across the preclinical, transitional, and clinical dementia stages. We conducted pre-registered searches of three databases from their inception to November 2024. The standardized mean difference (SMD) with 95 % CIs were combined in random-effects meta-analyses. Prospective studies based on self-reports of personality (13 studies; N = 6895) found subtle changes in the preclinical and transitional stages (SMD = 0–0.2), which became more pronounced (SMD = 0.3–0.5) in the clinical stage. Retrospective studies based on informant ratings (26 studies; N = 1069) found smaller changes during mild cognitive impairment compared to dementia, with large (>1 SMD) increases in neuroticism and decreases in extraversion and conscientiousness. Surprisingly, changes in frontotemporal dementia were slightly smaller than those observed in Alzheimer’s disease. By triangulating findings across study designs, we conclude that personality changes are subtle and inconsistent in the early preclinical stage. Personality changes become significant and pronounced as the disease progresses, in line with the rise of emotional and behavioral symptoms. Future multimethod studies should examine to what extent the rate of change is related to the underlying neurodegenerative processes. Our findings provide a framework for interpreting the timing and magnitude of non-cognitive changes in dementia, informing disease monitoring and targeted symptom management.
痴呆症临床前到临床阶段人格改变的meta分析。
人格改变是痴呆症诊断的临床标准,但其在疾病阶段的进展尚不清楚。这项系统回顾和荟萃分析检查了临床前、过渡和临床痴呆阶段的五种主要人格特征的变化。我们对三个数据库从建立到2024年11月进行了预注册检索。标准化平均差(SMD)和95% ci在随机效应荟萃分析中合并。基于人格自我报告的前瞻性研究(13项研究;N = 6895)在临床前和过渡阶段(标准化平均差,SMD = 0-0.2)有细微变化,在临床阶段更为明显(SMD = 0.3-0.5)。基于举报人评分的回顾性研究(26项研究;N = 1069)发现,与痴呆相比,轻度认知障碍期间的变化较小,神经质(bbbb1 SMD)大幅增加,外向性和尽责性减少。令人惊讶的是,额颞叶痴呆患者的变化略小于阿尔茨海默病患者。通过对研究设计的结果进行三角测量,我们得出结论,人格变化在早期临床前阶段是微妙且不一致的,这对其在早期痴呆症诊断中的效用提出了质疑。随着疾病的发展,人格变化变得显著和明显,与情绪和行为症状的增加一致。未来的多方法研究应该检查变化率在多大程度上与潜在的神经退行性过程有关。我们的研究结果为解释痴呆症非认知变化的时间和程度提供了一个框架,为疾病监测和有针对性的症状管理提供了信息。

期刊介绍: With the rise in average human life expectancy, the impact of ageing and age-related diseases on our society has become increasingly significant. Ageing research is now a focal point for numerous laboratories, encompassing leaders in genetics, molecular and cellular biology, biochemistry, and behavior. Ageing Research Reviews (ARR) serves as a cornerstone in this field, addressing emerging trends. ARR aims to fill a substantial gap by providing critical reviews and viewpoints on evolving discoveries concerning the mechanisms of ageing and age-related diseases. The rapid progress in understanding the mechanisms controlling cellular proliferation, differentiation, and survival is unveiling new insights into the regulation of ageing. From telomerase to stem cells, and from energy to oxyradical metabolism, we are witnessing an exciting era in the multidisciplinary field of ageing research. The journal explores the cellular and molecular foundations of interventions that extend lifespan, such as caloric restriction. It identifies the underpinnings of manipulations that extend lifespan, shedding light on novel approaches for preventing age-related diseases. ARR publishes articles on focused topics selected from the expansive field of ageing research, with a particular emphasis on the cellular and molecular mechanisms of the aging process. This includes age-related diseases like cancer, cardiovascular disease, diabetes, and neurodegenerative disorders. The journal also covers applications of basic ageing research to lifespan extension and disease prevention, offering a comprehensive platform for advancing our understanding of this critical field.
