概括

抗N-甲基-D-酸盐受体脑炎导致认知缺陷,原因是左前前带皮层 (pgACC.L) 的异常. 这些pgACC.L变化与记忆和执行功能受损有关,可能作为疾病生物标志物.

科学领域:

神经科学是一个神经科学.
免疫学免疫学免疫学
放射学放射学是指放射学

背景情况:

抗N-甲基-D-酸盐受体 (NMDAR) 脑炎是一种自身免疫性疾病,导致显著的神经精神和认知障碍.
带带皮质与抗NMDAR脑炎的病理生理学有关,但具体的亚区域性改变仍然不清楚.

研究的目的:

调查抗NMDAR脑炎患者带带皮质皮质的亚区域功能和 perfusion 成像变化.
探索这些神经成像发现与认知缺陷之间的关系.
评估这些变化的潜力,作为疾病诊断和监测的生物标志物.

主要方法:

休息状态MRI (fALFF,DC,CBF) 和神经心理评估对38名抗NMDAR脑炎患者和30名健康对照进行.
进行了功能连接 (FC) 和CBF连接分析.
支持矢量机 (SVM) 用于根据成像特征对患者和对照进行分类.

主要成果:

患者表现出记忆和执行功能的认知障碍,以及焦虑.
在左前前带皮质 (pgACC.L) 中观察到fALFF,DC和CBF的减少.
发现pgACC.L和诸如副海马圈和前骨等区域之间减少了FC,以及改变了CBF连接. 这些变化与认知缺陷相关. SVM成功地将患者与对照区分开来.

结论:

左前前带皮层 (pgACC.L) 的异常是抗NMDAR脑炎的病理机制的核心.
在pgACC.L中的功能和 perfusion 影像变化可以作为疾病监测和诊断的有价值的生物标志物.

关键词:

Encephalitis l: Introduction

Encephalitis 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...

Encephalitis ll: Pathophysiology

Encephalitis 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...

Hepatic Encephalopathy

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic...
