概括
与荷兰成年人相比,冲绳老年人在执行功能任务期间的脑部活化较少,这表明潜在的认知策略或资源利用对健康衰老有所不同.
科学领域:
- 神经科学是一个神经科学.
- 认知衰老研究 认知衰老研究
- 相对老年学与老年学的比较
背景情况:
- 冲绳老年人以特殊的长寿和健康的衰老而闻名.
- 这项研究是首次比较冲绳和荷兰老年人执行功能期间的大脑活动.
研究的目的:
- 调查在冲绳与荷兰老年人执行功能任务期间大脑激活模式的差异.
- 探索不同人群中大脑激活,认知表现和健康衰老之间的潜在联系.
主要方法:
- 来自冲绳和荷兰的80名参与者 (65-80岁) 接受了功能近红外光谱学 (fNIRS).
- 脑激活 (血红蛋白水平) 在视觉工作记忆 (n-back) 和口语流性任务中被测量.
- 横向性指数分析了额叶皮层激活的情况.
主要成果:

Cognitive Development During Adulthood
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,...
Dementia l: Introduction
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
