- 神经学 神经学
背景情况:
- 急性髓性白血病 (AML) 治疗可能导致认知障碍.
- 淋巴系统功能障碍与神经系统疾病有关.
研究的目的:
- 在化疗后的AML患者中,使用沿周脉空间 (DTI-ALPS) 指数的扩散张力成像来评估淋巴功能.
- 在这个群体中探索淋巴功能和认知表现之间的关联.
主要方法:
- 通过使用脑磁共振成像和认知测试,评估了21名化疗后AML患者和20名健康对照.
- 测量的大脑脊髓液 (CSF) 容量,基底腺周血管空间 (BG-PVS) 容量,DTI-ALPS指数和血液氧气水平依赖的-CSF合.
- 分析了群体差异和淋巴体标记和认知得分之间的相关性.
主要成果:

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...
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...
