概括

纤维肌痛患者在白质 (WM) 区域的功能活动减少,与疼痛和情绪症状相关. 这些发现表明WM的功能变化是理解纤维肌痛病理生理学的关键.

科学领域:

神经科学是一个神经科学.
医疗成像医学成像
慢性疼痛研究慢性疼痛研究

背景情况:

纤维肌痛综合征 (FMS) 是一种常见的中央慢性疼痛障碍,原因不明.
白质 (WM) 对大脑通信至关重要,在FMS中已知结构性WM问题.
在FMS患者中WM的功能性变化仍然在很大程度上未被探索.

研究的目的:

为了研究FMS患者白质 (WM) 的功能神经变化.
确定功能性WM变化是否与观察到的结构变化相关.
探索FMS中WM功能变化和临床症状之间的关系.

主要方法:

与43名FMS患者和43名健康对照进行比较.
评估白质 (WM) 结构使用分数异构 (FA).
通过低频波动 (ALFF) 的静态振幅评估WM功能.

主要成果:

FMS患者在多个WM通道中表现出改变的FA,包括皮质脊髓通道 (CST) 和环膜/海马体.
在FMS患者中,在左侧CST,中侧 (ML) 和右侧环膜/海马体内发现了降低的ALFF值.
在右环膜/海马体和左ML的ALFF减少与焦虑,抑郁和疼痛严重程度有积极的相关性.

结论:

这项研究提供了通过WM功能信号对FMS机制的初步见解.
在FMS中减少WM功能激活表明潜在的病理生理学作用.
确定了FMS干预的潜在治疗目标,重点是白质.

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
