概括
如果仅依靠大脑MRI,可能会错过韦尼克脑病 (WE) 诊断. 在患有MRI病变的患者中观察到较低的维生素B1水平和较高的治疗剂量,但酒精主义较少发生.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
背景情况:
- 沃尼克脑病 (Wernicke encephalopathy,简称WE) 是一种神经疾病,通常与胺缺乏有关.
- 脑磁共振成像 (MRI) 是WE的关键诊断工具,但其灵敏度可能有所不同.
- 识别影响WE诊断的因素对于及时干预至关重要.
研究的目的:
- 调查维尼克脑病变 (WE) 与大脑MRI发现之间的关联.
- 为了比较WE患者具有和没有MRI病变的特征.
主要方法:
- 对26名WE患者的回顾性分析 (2008年5月至2022年9月).
- 患者被分为MRI阳性组 (MPG) 和MRI阴性组 (MNG).
- 在MPG和MNG之间对人口,临床,实验室和治疗参数进行比较.
主要成果:
- 在MPG中,有17名患者.
- 与MNG相比,MPG的酒精滥用率较低 (10.0%与77.8%,P=0.025).
- 在MPG中,维生素B1水平显著降低 (中位数为10.0 ng/ml与29.0 ng/ml,P < 0.001),并且获得更高的维生素B1治疗剂量 (中位数为1900 mg与600 mg,P = 0.016).
结论:
- 大脑MRI检测结果本身可能不足以诊断凡尼克脑病变的所有病例.
- 如果诊断决策严重依赖MRI结果,酒精WE可能会被忽视.
- 较低的维生素B1水平和更高的治疗需求与MRI阳性WE病例有关.

01:10Higher Mental Functions of the Brain: Language
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
01:26Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
01:22Dementia 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...
