概括
刚果老年人的白质超强度 (WMH) 与痴呆症,男性性别和年龄有关. 这些发现突出了撒哈拉以南非洲白质病的关键预测因素,尽管与典型的心血管风险因素缺乏关联.
科学领域:
- 神经学 神经学
- 神经成像是一种神经成像.
- 老年病的医生 老年病的医生
背景情况:
- 白质超强度 (WMH) 与心血管风险因素和痴呆症有关.
- 在低收入国家,特别是刚果民主共和国 (DRC),对WMH的研究是有限的.
- 刚果民主共和国面临着人口快速老龄化,心血管和痴呆相关疾病的发病率不断上升.
研究的目的:
- 为了评估与WMH相关的健康因素,在撒哈拉以南非洲 (SSA) 的老年人中.
- 调查 WMH 与刚果人口中的各种健康和人口因素之间的关系.
- 为了解决关于贫困人口中WMH的研究缺口.
主要方法:
- 一项涉及刚果民主共和国77名成年人的横截面研究.
- 神经成像用于评估WMH体积,临床评估,实验室测试和问卷.
- 线性回归模型 (简单和多重) 来分析WMH与神经状态,年龄,性别和心血管风险因素等预测因素之间的关联.
主要成果:
- 在多重回归模型中,WMH与痴呆症 (expβ=1.97,p=0.001),男性性别 (expβ=0.54,p=0.003) 和年龄 (expβ=1.03,p=0.03) 有显著的关联.
- 大多数参与者 (61%) 患有痴呆症,平均年龄为73岁.
- 在WMH和常见的心血管风险因素 (高血压,糖尿病,吸烟,肥胖,高胆固醇) 之间没有发现显著的关联.
结论:
- 刚果人口中的WMH与神经状态 (痴呆症),性别和年龄有显著的关联.
- 识别这些预测因素可以帮助诊断和管理SSA/DRC的白质疾病.
- 这些发现对于在神经成像可访问性有限的地区制定预防策略至关重要.

21
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 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...
