概括
阿尔茨海默氏病 (AD) 中的大脑血管病理包括两个主要途径:独立于AD的动脉硬化和与AD病理相关的脑粉样血管病变 (CAA). 了解这些不同的途径对于AD治疗策略至关重要.
科学领域:
- 神经学 神经学
- 神经科学是一个神经科学.
- 病理学 病理学 病理学
背景情况:
- 脑血管病理是神经退行性疾病的一个重要因素,但它与阿尔茨海默氏症 (AD) 病理学的关系需要进一步澄清.
- 不同的神经退行性路径可能来自脑血管和AD病理的独立或协同作用.
- 阿尔茨海默病神经成像计划 (ADNI) 为研究这些复杂的相互作用提供了有价值的数据.
研究的目的:
- 评估各种死后脑血管标记物及其体内神经影像,临床和神经病理相关物之间的相互作用.
- 通过检查脑血管病理和AD病理之间的关系来阐明不同的神经退行性途径.
- 确定脑血管病理是否会影响阿尔茨海默氏病的疾病修饰疗法的适用性或不良事件.
主要方法:
- 在109人中进行脑血管病理的尸体鉴定,包括动脉样硬化,脑粉样血管病变 (CAA),动脉样硬化和心脏病发作.
- 评估体内神经成像 (例如皮层厚度,白质病变,微分异性质),认知功能和神经病理学测量 (例如AD病理学,莱维体,TDP-43).
- 统计分析,包括多重对应分析和回归模型,以确定脑血管标志物和其他措施之间的关联.
主要成果:
- 动脉样硬化和CAA被确定为主要的脑血管标志物.
- 严重的动脉样硬化与白质病变负担和海马缩相关,独立于AD病理.
- 严重的CAA与白质完整性降低,皮质缩,AD病理以及较差的记忆功能有关.
结论:
- 存在两个不同的脑血管路径:一个是由动脉样硬化驱动的,与AD病理无关,另一个是由CAA驱动的,与AD病理相关.
- 脑血管病理与AD病理的关联取决于病因.
- 这些发现对患者的适用性和与阿尔茨海默氏症疾病修饰疗法相关的潜在不良事件有影响.

Alzheimer's Disease: Overview
1.5K
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...

The Arch of Aorta
1.5K
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

Alzheimer's Disease: Treatment
736
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Arteries of the Head and Neck
2.9K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Cerebrum: Anatomical Overview II
4.2K
Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...
