概括

通过沿周血管空间 (DTI-ALPS) 指数进行扩散张力图像分析来测量的淋巴腺功能障碍与的认知障碍有关. 较低的DTI-ALPS指数和增加的胆脉体积是叶发症中语义流性缺陷的危险因素.

科学领域:

神经成像是一种神经成像.
神经学神经学
的研究研究.

背景情况:

叶 (TLE) 经常与认知缺陷有关.
负责大脑中废物清理的淋巴系统可能在神经系统疾病中发挥作用.
淋巴系统的功能障碍与各种大脑疾病有关.

研究的目的:

调查淋巴系统功能障碍和单边TLE患者的认知障碍之间的关联.
识别与淋巴功能相关的成像生物标志物及其与认知表现的相关性.

主要方法:

对38名单边TLE患者和26名健康对照 (HCs) 的回顾性研究.
使用扩散张力图像分析对周围血管空间 (DTI-ALPS) 索引和胆脉体积 (CPV) 进行评估淋巴功能.
进行综合的神经心理测试,包括语义口语流 (SVF),以评估认知功能.

主要成果:

与HC患者相比,TLE患者的DTI-ALPS指数值显着较低,特别是在半径侧半球.
认知评估显示,TLE患者在多个领域的得分较低,包括SVF.
DTI-ALPS指数和CPV与SVF表现有显著的关联,DTI-ALPS下降和CPV增加被确定为语义流性损害的独立风险因素.

结论:

由降低的DTI-ALPS指数和扩大的CPV指出的淋巴功能障碍与单边TLE中的语义流性损伤有显著的关联.
这些成像标记可以作为TLE认知缺陷的潜在指标.
这些发现突显了淋巴系统在TLE病理生理学中的作用,并表明了潜在的治疗点.

Language and Cognition

Language and Cognition

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.

Long-term Depression

Long-term Depression

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.
