概括
大脑小灰质缩和功能连接性改变与皮质下血管轻度认知障碍 (svMCI) 相关,特别是抑郁症. 这些大脑变化与认知和抑郁症状相关,表明了诊断潜力.
科学领域:
- 神经成像是一种神经成像.
- 神经学 神经学
- 老年学是一门学科.
背景情况:
- 皮层下血管轻度认知障碍 (svMCI) 通常与抑郁症同时发生,影响患者的生活质量.
- 小脑变化与认知衰退和抑郁症有关,但它们在抑郁症中svMCI中的具体作用尚不清楚.
研究的目的:
- 在患有抑郁症和没有抑郁症的svMCI患者中调查小脑灰质体积和功能变化.
- 将这些小脑变化与认知和抑郁症状相关联.
主要方法:
- 招募了16名患有抑郁症的svMCI (svMCI+D),15名没有抑郁症的svMCI (svMCI-D) 和12名对照.
- 使用多式核磁共振成像来评估小脑灰质体积和静止状态功能连接 (RSFC).
- 分析了RSFC与MoCA和HAMD得分之间的相关性.
主要成果:

01:22Cerebral Edema ll: Pathophysiology
19
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 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...
