概括

皮层骨干综合征 (CBS) 在分子层面上是多样化的,病理是最常见的. 生物标记子类型揭示了不同的患者群体,有助于个性化治疗运动和认知障碍.

科学领域:

神经科学是一个神经科学.
神经学神经学
生物标志物研究生物标志物研究

背景情况:

皮质皮质综合征 (CBS) 呈现出渐进的运动和皮质功能障碍.
肺结核综合征通常是由tau病理 (例如,渐进性超核性,皮质核退行),阿尔茨海默病 (AD),或不太常见的莱维型α-synucleinopathies (LTS) 和TDP-43蛋白质病变) 引起的.
在CBS中,这些不同的潜在病理的临床影响尚不清楚.

研究的目的:

用粉样蛋白-β (Aβ),Tau和α-synuclein (αSyn) 的体内生物标志物对CBS患者进行分类.
评估这种基于生物标志物的分层在CBS患者中的临床相关性.

主要方法:

对50名CBS患者进行了前性队列研究.
生物标志物分析包括CSF Aβ42/40,Aβ-PET,tau-PET和αSyn种子放大试验.
脑神经纤维光链 (NfL) 被用作神经退行症标志物,根据生物标志物阳性,患者被分为六组.

主要成果:

在90%的CBS病例中检测到tau阳性,Aβ在28%,αSyn在24%.
患者分层显示:52%的tau占主导病理,18%的AD,10%的AD+LTS,10%的tau占主导+LTS,4%的孤立LTS和6%的未分类.
在AD-CBS (36%) 中,αSyn阳性比tau主导-CBS (16%) 更频繁. Aβ阳性与更大的认知障碍相关,而tau阳性与更糟糕的运动症状相关. αSyn阳性与较轻的运动症状,进展较慢和较低的NfL水平有关.

结论:

皮层基底综合征表现出显著的分子异质性.
基于生物标志物的CBS分类可以提高诊断精度.
这种方法可能有助于为CBS患者制定个性化治疗策略.

Classification of Skeletal Muscle Fibers

Classification of Skeletal Muscle Fibers

Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.

Seizures: Classification

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
