概括

脑脊液 (CSF) 和血液中的神经纤维光链 (NfL) 水平在多系统性缩 (MSA) 患者中比健康对照,帕金森病和勒维体痴呆症患者高. 这一发现有助于诊断MSA.

科学领域:

神经科学是一个神经科学.
生物化学生化学
临床神经学临床神经学

背景情况:

多重系统缩 (MSA) 诊断是具有挑战性的,因为症状与其他神经退行性疾病重叠,特别是α-synucleinopathies.
生物标志物对于将MSA与帕金森病 (PD) 和勒维体痴呆症 (LBD) 等疾病区分开来至关重要.

研究的目的:

系统地审查和元分析MSA患者和健康对照者 (HC),PD患者和LBD患者之间脑脊液 (CSF) 和血液神经丝轻链 (NfL) 水平的差异.
评估CSF和血液NfL在区分MSA与HC,PD,LBD,渐进性上核麻 (PSP) 和皮质核退行 (CBD) 的诊断性能.

主要方法:

我们对MEDLINE和EMBASE进行了全面的文献搜索,以查找相关的病例控制研究.
在不同患者组中计算了CSF和血液NfL水平的标准化平均差异 (SMD).
使用Q和I^2统计数据来评估统计异质性.

主要成果:

25项研究被纳入了定量综合.
与HC,PD和LBD患者相比,在MSA患者中观察到CSF和血液NfL水平升高.
对于NfL的诊断准确度在区分MSA与HC和PD,中度与LBD,以及低于最佳的与PSP和CBD的区分方面非常出色.

结论:

与HC,PD和LBD相比,MSA患者的CSF和循环NfL水平显著升高.
脑流和血液NfL显示出对MSA的有希望的诊断实用性,特别是对HC和PD.
为了优化诊断特性,需要进一步标准化和建立参考NfL间隔.

Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Multiple Sclerosis l: Introduction

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Alterations in Muscle Tone lll

Alterations in Muscle Tone lll

Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
