概括
计算机认知训练 (CCT) 通过增强大脑连接,改善了轻度认知障碍 (MCI) 患者的记忆. 这种非记忆训练显示了对记忆功能及其神经基础的转移效应.
科学领域:
- 神经科学是一个神经科学.
- 认知心理学 认知心理学
- 医学研究 医学研究
背景情况:
- 计算机化认知训练 (CCT) 在认知衰退方面得到了探索.
- 在轻度认知障碍 (MCI) 中,CCT对记忆及其神经机制的转移效应尚不清楚.
- 这项研究研究了非记忆CCT对MCI患者记忆的转移效应.
研究的目的:
- 为了确定多域CCT,不包括记忆练习,可以改善MCI患者的记忆功能.
- 探索任何观察到的记忆改善的神经基础.
- 评估CCT对MCI患者记忆的转移效应.
主要方法:
- 一个随机对照试验,涉及MCI患者被分配到CCT或对照组 (教育书籍).
- 该组接受了为期8周的培训,不包括特定于记忆的任务.
- 评估包括记忆测试,认知/非认知尺度和休息状态fMRI用于神经网络分析.
主要成果:
- 与对照组相比,CCT组显示记忆功能的显著改善 (P=0.03).
- 改善的记忆与海马前额和状尾网络的连接性增加有关.
- 两组之间在其他认知或非认知领域没有发现显著差异.
结论:
- 在没有直接记忆训练的8周多域CCT增强了MCI患者的记忆功能.
- 训练恢复了与记忆相关的关键大脑区域 (海马和中间时) 的功能连接.

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
114
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

Cognitive Development During Adulthood
78
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,...
