- 神经学 神经学
- 医疗成像医学成像
背景情况:
- 晚发性 (LOE) 与认知能力下降有关.
- 慢性失眠是老年人常见的并发症.
- 淋巴系统 (GS) 在脑废物清理中起着至关重要的作用,可能与神经退行过程有关.
研究的目的:
- 为了研究淋巴系统 (GS) 功能障碍和晚发性 (LOE) 患者的认知衰退之间的关联.
- 评估伴随性慢性失眠对LOE患者GS功能和认知状态的影响.
- 为了利用在周脉空间 (DTI-ALPS) 上的扩散张力成像来量化GS函数.
主要方法:
- 招募了42名老年LOE患者 (17名慢性失眠) 和22名健康对照 (HC).
- 使用迷你精神状态检查 (MMSE) 评估认知功能.
- 测量了血生物标志物 (Aβ42 / Aβ40比),并使用DTI-ALPS来评估GS功能.
主要成果:
- 与HC患者相比,LOE患者的DTI-ALPS指数和Aβ42/40比率明显较低.
- 患有慢性失眠的LOE患者表现出更低的Aβ42/40和DTI-ALPS指数值.

Long-term Depression
27.3K
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.

Cerebral Edema ll: Pathophysiology
31
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this...

Dementia l: Introduction
35
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...
