Abstract

BACKGROUND

We explored the associations of comorbidities with cognitive deterioration, institutionalization, and mortality in biomarker-confirmed Alzheimer’s disease (AD) dementia.

METHODS

We conducted a Swedish Register-based cohort study consisting of 10,857 people (mean age 74 years) with diagnosed dementia and positive AD biomarkers (CSF Aβ/P-tau ratio). Cognitive function was measured by mini-mental state examination (MMSE). Comorbidities by human body organ systems (e.g., diseases of the circulatory system) and six selected comorbidities: type-2 diabetes (T2DM), ischemic heart disease (IHD), stroke, chronic kidney disease (CKD), inflammatory bowel disease, and depression, were analyzed. Multistate Cox regressions assessed the associations of comorbidities with cognitive deterioration, institutionalization, and death.

RESULTS

Only T2DM and IHD were associated with cognitive deterioration. Mental disorders, T2DM, and stroke were linked to higher hazards of institutionalization. Endocrine-metabolic disorders, circulatory system diseases, and CKD were associated with higher mortality rates.

CONCLUSIONS

Comorbidities may help inform the prognosis of biomarker-confirmed AD dementia.

摘要

背景

我们探讨了共病与生物标志物确诊的阿尔茨海默病（AD）痴呆患者认知功能衰退、入住养老院及死亡率之间的关联。

方法

我们开展了一项基于瑞典登记册的队列研究，纳入了10857名（平均年龄74岁）已确诊痴呆且AD生物标志物（脑脊液Aβ/P-tau比值）呈阳性的患者。通过简易精神状态检查表（MMSE）评估认知功能。分析了按人体器官系统分类的共病情况（如循环系统疾病）以及六种选定的共病：2型糖尿病（T2DM）、缺血性心脏病（IHD）、中风、慢性肾脏病（CKD）、炎症性肠病和抑郁症。多状态Cox回归分析评估了共病与认知功能衰退、入住养老院及死亡之间的关联。
