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.
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.
