概括
平衡自动性对老年人双重任务干扰的影响最小. 相反,性别和认知状态显著影响平衡控制,特别是在双重支持立场.
科学领域:
- 老年学是一门学科.
- 神经科学是一个神经科学.
- 生物力学 生物力学
背景情况:
- 与年龄相关的下降影响了老年人双重任务 (DT) 的表现.
- DT干扰与注意力资源和平衡自动性有关.
- 轻度认知障碍 (MCI) 可能会降低感觉运动能力,增加对平衡的注意力需求.
研究的目的:
- 调查自动性是否影响DT期间MCI的老年人的平衡稳定性.
- 要确定这种关系是否随着平衡任务的难度而变化.
主要方法:
- 67名老年人 (23名患有MCI) 在双重支和双重支的姿势中执行单一和双重任务 (数学计数).
- 压力中心 (COP) 摆动速度 (Vcop) 用力板测量.
- 回归分析评估了基线摇摆对Vcop的DT成本 (DTC) 的贡献,控制年龄,认知得分,性别和认知状态.
主要成果:
- 基线摇摆解释了Vcop.的DTC中最小的差异 (0.25% - 4%).
- 性别和认知状态解释了12%-20%的双重支持立场的差异,但不是双重支持立场.
结论:
- 摇摆对老年人中DT干扰的影响很小.
- 性别和认知状态是平衡控制中更重要的因素.
- 这些因素对于了解老年人群,特别是患有MCI的人群的平衡至关重要.

01:16Interference and Decay
394
Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
174
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
