概括

随着时间的推移,ALS与认知障碍的脑网络随着时间的推移而变化,最初类似于纯动力ALS,后来进展到类似于bvFTD的模式.

科学领域:

神经科学是一个神经科学.
神经学神经学
大脑网络分析脑网络分析

背景情况:

肌缩侧面硬化症 (ALS) 和行为变异前性痴呆症 (bvFTD) 有关,ALS包括纯运动和认知/行为受损的形式.
有认知/行为障碍的ALS (ALSci/bi) 假设可以弥合ALS纯动力和bvFTD之间的差距.
了解ALSci/bi中的动态大脑网络变化对于阐明这种疾病谱系至关重要.

研究的目的:

为了研究ALSci/bi患者大脑网络拓学的纵向变化.
将这些变化与ALS纯动力和bvFTD患者的变化进行比较.
要确定ALSci/bi是否代表了一种随着时间的推移而演变的光谱.

主要方法:

在ALS纯动力,ALSci/bi和bvFTD队列中的纵向静止状态磁脑电图 (MEG) 记录.
使用特定频段 (theta和beta) 的振幅外相关性的功能连接性分析.
最小跨度树 (MST) 方法来构建和比较大脑网络的骨干.

主要成果:

在基线时,ALSci/bi-theta频段网络拓与ALS纯电机相似,而不是bvFTD.
通过随访 (5个月),ALSci/双β频网络相似性从ALS纯电机转移到bvFTD.
这些发现表明ALSci/bi患者的大脑网络组织的时间进展.

结论:

在ALSci/bi患者的大脑网络拓随着时间的推移而演变.
这种演变表明ALS-bvFTD疾病谱的动态进展.
该研究强调了MEG和网络分析在了解神经退行性疾病进展方面的有用性.

Alzheimer Disease l: Introduction

Alzheimer Disease l: Introduction

Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...

Alzheimer Disease ll: Pathophysiology

Alzheimer Disease ll: Pathophysiology

Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
