概括
小脑梗塞 (CI) 往往伴有头,特别是后部或前部较低大脑小动脉的参与. 眼部运动异常,如动入侵和异常平滑的追逐,是CI的关键诊断指标.
科学领域:
- 神经科学是一个神经科学.
- 神经学 神经学
- 眼科医生 眼科 眼科
背景情况:
- 小脑梗塞 (CI) 是一个重要的神经事件.
- 了解CI中的前体和眼部运动发现对于诊断至关重要.
- 将CI与其他前体障碍区分开来,例如急性单侧前体障碍 (AUVP) 可能具有挑战性.
研究的目的:
- 在患有小脑梗塞 (CI) 的患者中,划出前庭和眼部运动功能障碍的特征模式.
- 将这些发现与急性单侧前庭病变 (AUVP) 中观察到的结果进行比较,以确定诊断标记.
- 研究小脑病变的位置与特定的临床表现之间的关系.
主要方法:
- 对前体和眼部运动测试结果的回顾性分析.
- 包括23名被诊断为小脑梗塞 (CI) 的患者.
- 与32名被诊断患有急性单侧静脉病变 (AUVP) 的患者进行比较.
主要成果:
- 后下大脑小动脉 (PICA) 区域梗塞在CI中最常见.
- 在PICA或前下大脑动脉 (AICA) 心脏病发作中,头是最常见的;在上大脑动脉 (SCA) 病变中,头更常见.
- 与AUVP患者相比,CI患者的萨卡德异常,平滑追逐 (SP) 和萨卡德入侵明显更频繁 (p <0.05).
- 在47.8%的CI患者中,水平动异常,而在AUVP中为0%.
- 在56.5%的CI患者中,水平平滑追求受损,通常是双边的,而在AUVP中,通常是单边的28.1%.
- 主观视觉垂直 (SVV) 偏差模式在CI和AUVP之间有所不同,CI显示了受影响和未受影响两侧的偏差.
结论:

Major Somatic Sensory Pathways
851
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

Indirect Motor Pathways
1.4K
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...

The Vestibular System
39.3K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Cerebellum: Anatomical Regions
1.4K
The cerebellum, also known as the "little brain," is located in the posterior cranial fossa, inferior to the tentorium cerebelli and dorsal to the brainstem. It plays a significant role in motor control, coordination, and proprioception.
Cerebellar Structure
Externally, the cerebellum features a highly convoluted surface with numerous folia (narrow ridges) separated by shallow sulci (grooves). The cerebellum is divided into two hemispheres by a thin median structure known as the vermis....

Equilibrium and Balance
4.3K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Brainstem
1.6K
The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a vital role in relaying information and controlling critical life functions. It comprises three primary regions: the midbrain, pons, and medulla oblongata.
The Midbrain
The midbrain is located beneath the diencephalon and connects the cerebrum with the lower parts of the brain. The cerebral peduncles are prominent midbrain structures that house the...
