概括
在认知能力下降之前,慢步的老年人表现出较差的精神运动功能和代谢问题. 早期评估运动障碍可能有助于减缓痴呆症的进展.
科学领域:
- 神经学 神经学
- 老年学是一门学科.
- 代谢综合征是代谢综合征的一种.
背景情况:
- 认知障碍和痴呆症是老年人群的重大健康问题.
- 运动障碍,如慢步,可能会先于认知能力下降,这表明潜在的共享途径.
- 识别认知障碍和先前移动性问题的老年人独特的个人资料对于了解疾病进展至关重要.
研究的目的:
- 为了确定认知障碍或痴呆症的老年人的认知和健康状况,并有缓慢步行的历史.
- 调查先前的运动障碍是否代表了导致认知障碍或痴呆的特定途径.
主要方法:
- 使用了追溯纵向研究设计.
- 在老年人 (≥65岁) 与 (n=57) 和没有 (n=86) 缓慢步行的认知和健康状况进行了比较,在症状出现前长达14年.
- 用线性混合效应模型分析了经过平均7年前症状评估的纵向认知测量和生物标志物.
主要成果:
- 步行缓慢的个体在心理运动速度 (数字符号替换测试) 和手动灵敏度 (皮板测试) 中表现较差.
- 缓慢步行组具有不利的代谢和血管特征,包括更高的BMI,腰围,静脉血压和葡萄糖水平的增加.
- 与线粒体功能相关的脂质 lysophosphatidylcholine 18: 2 的较低水平在缓慢步行组中观察到,他们也更有可能使用高血压和高胆固醇血症的药物.
结论:
- 在认知障碍的老年人中,先前的缓慢步行与精神运动速度,手工敏捷性和代谢/血管健康不良的症状前缺陷有关.
- 与线粒体功能相关的较低脂质水平在那些先前慢步的人群中被发现.
- 在行动障碍患者中,早期评估和管理代谢和血管功能障碍可能是减缓认知衰退和痴呆症进展的关键.

Cognitive Development During Adulthood
111
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Alzheimer's Disease: Overview
487
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...
