概括
多发性硬化症 (MS) 中的等离子体神经丝光链 (pNfL) 与残疾和认知处理速度相关. 高等教育可能提供神经保护,而患者报告的结果显示没有显著的PNfL关联.
科学领域:
- 神经科学是一个神经科学.
- 临床神经学 临床神经学
- 生物标志物研究 生物标志物研究
背景情况:
- 多发性硬化症 (MS) 是一种慢性神经系统疾病,其特征是神经炎症和神经退行.
- 血神经纤维光链 (pNfL) 是MS中神经轴突损伤的敏感生物标志物.
- 了解pNfL,认知功能和患者报告的结果 (PRO) 之间的关系对于MS管理至关重要.
研究的目的:
- 研究血神经纤维光链 (pNfL) 水平与MS患者 (PwMS) 的认知表现之间的联系.
- 探索pNfL与患者报告的各种结果 (PROs) 之间的关系,包括疲劳,抑郁,焦虑和睡眠质量.
- 确定人口统计学因素 (如教育程度) 对MS的pNfL水平的影响.
主要方法:
- 一项涉及211名多发性硬化症患者 (PwMS) 的横截面研究.
- 数据收集包括血PNFL水平,扩展残疾状态量表 (EDSS),认知测试 (SDMT,CVLT II,BVMT-R) 和PROs (MFIS,BDI-II,BAI,PSQI).数据收集包括血PNFL水平,扩展残疾状态量表 (EDSS),认知测试 (SDMT,CVLT II,BVMT-R) 和PROs (MFIS,BDI-II,BAI,PSQI).
- 统计分析采用多变量线性回归和逻辑回归模型.
主要成果:
- 更高的教育程度与较低的PNFL水平有显著的关联.
- 增加的EDSS分数和受损的符号数字模式测试 (SDMT) 性能与较高的PNfL水平有关.
- 在pNfL和其他认知测试 (CVLT II,BVMT-R) 或PROs (MFIS,BDI-II,BAI,PSQI) 之间没有发现显著的关联.
结论:
- 在MS中神经轴突损伤与增加的残疾和注意力/处理速度的降低有关.
- 更高的教育程度可能会对MS中神经轴突损伤产生保护作用.
- 评估的PROs没有显示与pNfL的显著关联,可能是由于测量限制或异质性.

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.
