概括

在特定的大脑区域的白质过强度 (WMH) 与认知衰退患者的冷漠和过度活动有关. 了解这些联系可能会揭示小血管疾病影响行为的机制.

科学领域:

神经成像是一种神经成像.
神经学神经学
老年病的医生老年病的医生

背景情况:

白质过强度 (WMH) 与痴呆症中的神经精神症状有关.
在特定的白质 (WM) 区域中WMH的功能影响仍然不清楚.

研究的目的:

调查WMH负担在主要WM纤维类和具有明显神经精神综合征的个体区域之间的关联.
利用一个大型的多中心数据集来探索管道综合征的特异性.

主要方法:

来自七个记忆诊所队列 (Meta VCI Map联盟) 的协调的神经成像和神经精神病学数据.
基于类的分析协会, commissural,和投射纤维.
对11个单独的WM区域进行了兴趣区域分析,以评估WMH体积与多动,精神病,情感和冷漠综合征的关联.

主要成果:

投射纤维中WMH体积增加与较大的冷漠度相关.
相关联的WMH, commissural和投射纤维与过度活跃有关,特别是在下面的前后带,大和前面的乳头辐射中.
在未切割的囊和小子中的WMH也与增加的冷漠有关. 没有发现与情感或精神病综合征的联系.

结论:

结果表明,与冷漠和过度活跃相关的WMH负担中有管道综合征的特异性.
由WMH破坏特定的神经元通路可能是记忆诊所患者情绪和行为失调的基础.
这突出了小血管疾病影响情绪和行为调节的潜在机制.

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.

Dementia l: Introduction

Dementia l: Introduction

Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
