概括

脑前额叶皮质 (PFC) 中的铁积累与认知衰退和神经退行有关. 磁共振成像 (MRI) 可以量化这种铁,有助于理解衰老和疾病的影响.

科学领域:

神经成像是一种神经成像.
神经科学是一个神经科学.
生物标志物生物标志物

背景情况:

前额叶皮层 (PFC) 的铁积累与神经退行和认知衰退有关.
磁共振成像 (MRI) 提供了对大脑铁沉积的非侵入性量化.

研究的目的:

审查基于MRI评估PFC铁在健康个体和神经退行性疾病患者的证据.
探索PFC铁在衰老和神经退行过程中的作用.

主要方法:

在PubMed,Scopus,Web of Science和Embase的系统文献综述.
包括MRI技术,如敏感度加权成像 (SWI),定量敏感度映射 (QSM) 和R2*映射.
来自12项纳入研究的数据的叙述综合.

主要成果:

增加PFC铁与神经退行性疾病中的认知障碍相关.
在健康的衰老中,PFC铁的积累随着年龄的增长而增加,与较差的认知和降低的多巴胺信号传递有关.
像QSM这样的MRI技术可以量化PFC铁在衰老和神经退行.

结论:

通过MRI检测到的PFC铁水平升高可能会导致神经退行和认知能力下降.
核磁共振是评估PFC铁的敏感工具,对于理解神经退行病原和大脑衰老至关重要.
需要进一步的纵向研究,结合先进的MRI和认知评估.

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's Disease: Overview

Alzheimer's Disease: Overview

Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...
