Abstract

Introduction: It is unclear how dementia affects loss in life expectancy (LE). In this registry-based study, we aimed to study sex differences in LE and loss in LE in dementia, mild cognitive impairment (MCI), and subjective cognitive decline (SCD).

Methods: A total of 16,358 patients diagnosed with dementia, MCI, or SCD from the Norwegian Registry of Persons Assessed for Cognitive Symptoms (NorCog) during 2009-2022 were included and followed up for mortality. Sex differences in LE and loss in LE were predicted using flexible parametric survival models and sex-specific mortality in the general population as reference.

Results: Among dementia patients, women with dementia had the largest loss in LE: 17 years loss at 60 years; correspondingly, men lost 13.5 years. Similar patterns were observed for MCI and dementia subtypes.

Discussion: Women with dementia or MCI had a larger loss in LE compared to men with these diagnoses.

Highlights: Women with dementia had the largest loss in life expectancy compared to the general population.The excess female loss in life expectancy was also evident for all the dementia subtypes and for mild cognitive impairment.The loss in life expectancy was more pronounced in younger patients with dementia, with a loss of 17 years in women at 60 years of age. Men, in comparison, lost 13.5 years at the same age.Subjective cognitive decline was associated with a minor loss in life expectancy in both sexes.

痴呆、轻度认知障碍(MCI)和主观认知衰退(SCD)患者预期寿命的性别差异。
目前尚不清楚痴呆症如何影响预期寿命(LE)的损失。在这项基于登记的研究中,我们旨在研究痴呆、轻度认知障碍(MCI)和主观认知衰退(SCD)患者的LE和LE损失的性别差异。方法:2009-2022年间,共有16,358名来自挪威认知症状评估人员登记处(NorCog)的诊断为痴呆、MCI或SCD的患者被纳入研究,并随访死亡率。使用灵活的参数生存模型和一般人群的性别特异性死亡率作为参考,预测LE的性别差异和LE的损失。结果:痴呆患者中,女性痴呆患者的LE损失最大:60岁时损失17年;相应地,男性寿命减少13.5岁。在轻度认知障碍和痴呆亚型中也观察到类似的模式。讨论:患有痴呆或轻度认知障碍的女性与患有这些诊断的男性相比,LE的损失更大。重点:与一般人群相比,患痴呆症的女性预期寿命损失最大。女性预期寿命的超额损失在所有痴呆亚型和轻度认知障碍中也很明显。预期寿命的减少在年轻的痴呆症患者中更为明显,60岁的女性预期寿命减少17年。相比之下,同一年龄段的男性寿命减少了13.5岁。主观认知能力下降与男女预期寿命的轻微下降有关。

期刊介绍: Alzheimer''s & Dementia: Diagnosis, Assessment & Disease Monitoring (DADM) is an open access, peer-reviewed, journal from the Alzheimer''s Association® that will publish new research that reports the discovery, development and validation of instruments, technologies, algorithms, and innovative processes. Papers will cover a range of topics interested in the early and accurate detection of individuals with memory complaints and/or among asymptomatic individuals at elevated risk for various forms of memory disorders. The expectation for published papers will be to translate fundamental knowledge about the neurobiology of the disease into practical reports that describe both the conceptual and methodological aspects of the submitted scientific inquiry. Published topics will explore the development of biomarkers, surrogate markers, and conceptual/methodological challenges. Publication priority will be given to papers that 1) describe putative surrogate markers that accurately track disease progression, 2) biomarkers that fulfill international regulatory requirements, 3) reports from large, well-characterized population-based cohorts that comprise the heterogeneity and diversity of asymptomatic individuals and 4) algorithmic development that considers multi-marker arrays (e.g., integrated-omics, genetics, biofluids, imaging, etc.) and advanced computational analytics and technologies.
