概括

脊髓缩 (SCA) 即使在患有多发性硬化症 (MS) 且大脑稳定的患者中也会进展,这表明神经退行. 监测SCA提供了关于MS进展的见解,特别是在稳定的病例中.

科学领域:

神经科学是一个神经科学.
放射学放射学是一门学科.
神经学神经学

背景情况:

脊髓缩 (SCA) 与多发性硬化症 (MS) 的残疾有关.
在MS进展中SCA的作用,独立于大脑缩,需要进一步调查.

研究的目的:

为了描述SCA的纵向进展.
在MS患者中确定SCA的临床相关物质,脑缩进展最小.

主要方法:

对120名多发性硬化患者进行了回顾性观察性研究,其中包括脑部MRI数据.
使用SIENA/X和JIM9.9对大脑和脊髓缩的量化.
基于疾病活动和大脑缩的分层,以隔离SCA进展.

主要成果:

观察到SCA进展 (-0.791%/年),即使在没有疾病活性证据 (NEDA) 标准的患者中也是如此.
SCA与大脑体积损失有很弱的相关性,但与T2病变体积或临床疾病活性没有相关性.
在NEDA-4患者中,较高的SCA率与较小的大脑T2损伤体积相关.

结论:

SCA可能表明MS中"纯"的神经退行性过程,独立于炎症.
评估SCA对于了解MS进展至关重要,特别是在临床稳定的患者中.
SCA评估为MS的疾病进展提供了关键的见解.

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.

Spinal Cord: Cross-sectional Anatomy

Spinal Cord: Cross-sectional Anatomy

The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.
