概括

大脑小血管疾病 (SVD) 是痴呆的主要原因. 这项案例研究证实了SVD患者的NOTCH3基因突变,突出了对脑自体主导动脉病变与皮层下心脏病发作和白细胞大脑病变 (CADASIL) 的基因测试的重要性.

科学领域:

神经学神经学
遗传学遗传学是一个
血管医学血管医学

背景情况:

大脑小血管疾病 (SVD) 约占痴呆症的45%,导致严重的残疾.
大脑自体主导动脉病变与皮下心脏病发作和白脑病变 (CADASIL) 是最常见的单一性中风原因,与NOTCH3基因突变有关.
NOTCH3突变导致脑血管中的蛋白质聚合,损害血液流动.

研究的目的:

介绍一个在69岁的女性患者身上诊断出CADASIL的病例.
强调广泛的SVD变化和家族中风病史的诊断意义.
突出基因测试在确认CADASIL中的作用.

主要方法:

一个69岁的女性的临床表现审查,患有脱节性关节炎,偏头痛和家族中风病史.
脑部成像包括非对比计算断层扫描 (CT) 和磁共振成像 (MRI) 来评估缺血变化.
基因检测用于识别NOTCH3基因中的致病变体.

主要成果:

CT显示了小血管缺血变化.
核磁共振扫描显示了急性右额叶心脏病发作,带有广泛的高信号强度变化,包括叶参与.
基因检测证实了异构合致病原性NOTCH3变体,诊断了CADASIL.

结论:

在患有广泛SVD的患者中,早发性中风或家族中风病史需要进行CADASIL测试.
对NOTCH3变异的遗传确认对于诊断CADASIL至关重要.
这一案例强调了确定SVD遗传原因的临床相关性.

Peripheral Artery Disease I: Introduction

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...
