概括

在患有先天性神经神经听力损失 (CSNHL) 的儿童中,淋巴系统功能降低,这是较低的DTI-ALPS指数所表明的. 这一发现可能有助于追踪疾病的进展,并了解CSNHL的神经机制.

科学领域:

神经科学是一个神经科学.
听力学听力学是指听力学.
放射学放射学是一门学科.

背景情况:

遗传性神经神经听力损失 (CSNHL) 的神经机制尚不清楚.
研究淋巴系统为CSNHL病理生理学提供了新的视角.

研究的目的:

评估CSNHL儿童的淋巴系统功能,使用周周血管空间 (DTI-ALPS) 的扩散张力成像.
为了比较CSNHL患者的DTI-ALPS指数与健康对照 (HCs).
在CSNHL中探索淋巴功能和年龄之间的关系.

主要方法:

招募了26名患有CSNHL和30名HC的儿童.
计算了所有参与者的DTI-ALPS指数.
分析了不同组的DTI-ALPS指数的差异,并将其与CSNHL组的年龄相关联.

主要成果:

与HC相比,患有CSNHL的儿童的DTI-ALPS指数明显较低 (1.49对1.61,p=0.002).
在z轴 (Dzzassoc) 上的协会纤维扩散率在CSNHL组显著更高 (p=0.003).
在患有CSNHL的儿童中,DTI-ALPS指数和年龄之间发现了显著的负相关性 (rho = -0.544,p=0.005).

结论:

这是第一个使用DTI-ALPS指数调查CSNHL儿童淋巴系统活动的研究.
在CSNHL儿童中观察到淋巴系统功能下降,与年龄相关.
DTI-ALPS指数可以作为CSNHL进展和治疗的生物标志物,帮助研究早期听力丧失的神经机制.

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.

Alzheimer Disease l: Introduction

Alzheimer Disease l: Introduction

Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...

Dementia l: Introduction

Dementia 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...
