概括
听力损失和血生物标志物 (神经丝光,质纤维酸性蛋白质,酸化-217) 的升高与成年人的认知能力下降有关. 这些因素代表着有助于痴呆风险的独特途径.
科学领域:
- 神经科学是一个神经科学.
- 老年学是指老年学的学科.
- 生物标志物 生物标志物
背景情况:
- 听力损失是一个可修改的痴呆症风险因素.
- 像NfL,GFAP和Ptau217这样的等离子体生物标志物表明神经退行和阿尔茨海默病 (AD) 病理.
研究的目的:
- 评估听力损失和血生物标志物与老年人认知功能之间的独立关联.
- 检查年龄是否会改变这些关联.
主要方法:
- 对373名来自老龄成人大脑连接组 (AABC) 研究的参与者的横截面研究.
- 听力通过NIH工具箱Words-in-Noise进行评估;通过临床前阿尔茨海默氏症认知复合 (PACC) 进行认知.
- 分析了等离子体生物标志物 (NfL,GFAP,tTau,Ptau217);用于关联的一般线性模型,对共变量进行调整.
主要成果:
- 听力损失独立地与较低的PACC分数相关 (β = -0.03,p < 0.001).
- 较高的NfL,GFAP和Ptau217水平与较差的认知功能有关.
- 年龄适度的生物标志物-认知联系,在65岁以上的人群中更强烈的关联.
结论:
- 听力损失和等离子体生物标志物代表了认知衰退的独立,附加的贡献者.
- 这些发现支持综合性痴呆风险模型和个性化认知监测策略.

Alzheimer's Disease: Overview
1.6K
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
560
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.
