概括
基于平板电脑的多模式训练在阿尔茨海默病 (AD) 患者的全球认知功能稳定了六个月. 然而,这种干预措施并没有在特定的认知领域或大脑结构中显著改善.
科学领域:
- 神经科学是一个神经科学.
- 老年学是一门学科.
- 认知科学 认知科学
背景情况:
- 计算机化认知训练对轻度认知障碍有希望,但对于阿尔茨海默病 (AD) 没有显示出类似的益处.
- 基于家庭的认知干预需要进一步研究在AD人群中的有效性.
- 这项研究研究了一种基于平板电脑的多模式培训计划,用于轻度至中度AD患者.
研究的目的:
- 评估为期六个月的基于平板电脑的多模式训练对轻度至中度AD患者的认知功能的影响.
- 为了评估干预后 (下) 皮层大脑结构体积的变化.
- 为了比较多式模式训练与接受传统认知练习的对照组的影响.
主要方法:
- 一个随机对照试验,比较了为期六个月的监督和无监督的基于平板电脑的多模式训练 (认知和身体练习) 与对照组 (纸和笔练习).
- 包括患有轻度至中度AD的参与者 (每组n=11).
- 用神经心理评估和结构性MRI (Freesurfer分析) 来测量认知功能和大脑体积.
主要成果:
- 干预组在六个月内保持了整体认知功能 (迷你心理状态检查),而对照组下降了 (p=.041).
- 在特定的认知领域 (如记忆,注意力或执行功能) 没有明显的改善.
- 两组之间没有发现大脑体积的显著差异.
结论:
- 基于平板电脑的多模式训练对六个月的轻度至中度AD的全球认知功能产生了积极的影响.
- 训练没有显示出可测量的转移效应到其他认知领域或大脑结构.
- 建议进一步进行高质量的纵向研究,以探索这种干预措施在AD管理中的潜力.

Alzheimer's Disease: Treatment
261
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Alzheimer's Disease: Overview
668
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...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
206
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
275
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,...

Parkinson's Disease: Treatment
380
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...
