概括
在患有轻度认知障碍 (MCI) 的个人中,语音口语流性比语义流性更早地下降. 语音流的早期下降可能有助于预测未来的阿尔茨海默病 (AD) 发展.
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
- 老年学是一门学科.
背景情况:
- 语义和语音语言流性的恶化是阿尔茨海默病 (AD) 的早期认知标志物.
- 轻度认知障碍 (MCI) 是正常衰老和AD之间的过渡阶段.
研究的目的:
- 为了确定哪种语言流利类型 (语义或语音) 在AD的进展中早些时候恶化.
- 评估口语流利性任务在区分MCI患者将转换为AD与那些不会的有用性.
主要方法:
- 对25名MCI患者和对照人群进行了口头流利任务.
- 进行了连续的神经心理评估,以随着时间的推移跟踪认知状态.
- 确定了8名MCI患者,他们在两年内转换为AD.
主要成果:
- 与MCI患者的语义语言流利相比,语音语言流利表现出较早的恶化.
- 在MCI和AD组之间观察到语言流性的统计学上显著差异.
- 在MCI患者与没有进展到AD的患者之间,在口语流性表现上没有发现显著差异.
结论:

Alzheimer's Disease: Overview
448
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...

Dementia

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.

Alzheimer's Disease: Treatment
165
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...

Language and Cognition
325
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
