概括
在酒精使用障碍 (AUD) 患者,特别是男性中,姿势不稳定性持续存在. 这与运动中心的大脑结构变化有关, 即使在清醒之后.
科学领域:
- 神经科学
- 神经学
- 关于成的研究
背景情况:
- 酒精使用障碍 (AUD) 患者的姿势不稳定和跌倒很常见,即使在戒酒后也会持续.
- 使用力盘分析和光谱分析量化姿势摇摆可以揭示干部震,这是不稳定的指标.
- 了解导致AUD持续不稳定的基本生理和大脑结构因素至关重要.
研究的目的:
- 调查AUD患者静静站立时导致姿势不稳定的生理和大脑结构因素.
- 在AUD中探索震,感官功能和大脑结构之间的关系.
- 确定与AUD持续的姿势不稳定相关的特定因素.
主要方法:
- 一项涉及292名参与者的混合截面/纵向研究 (120名男性/44名女性AUD,75名男性/53名女性对照).
- 使用力量板 (眼睛开/闭,脚在一起) 测试平衡,通过光谱分析测量姿势震动.
- 两点区分测试足底和结构MRI以评估运动中心的大脑体积.
主要成果:
- 在所有疾病中,AUD患者表现出比对照患者更大的姿势震,AUD男性的差异最为明显.
- 在AUD和对照组之间没有观察到对震的显著影响.
- 更大的震与运动中心 (补充运动皮质,乳头,白皮质,小脑白质) 的较小区域大脑体积相关,特别是在AUD男性中.
结论:
- 在AUD中,尤其是男性中,姿势不稳定与运动控制区域的结构性大脑变化有关.
- 这些发现表明神经生物学变化导致AUD持续的平衡缺陷,即使清醒.
- 前一年过度饮酒超过了指导方针,与AUD男性最显著的姿势不稳定迹象有关.

Parkinson's Disease: Overview
702
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Parkinson's Disease: Treatment
376
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

CNS Depressants: Alcohol and Nicotine
358
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Alzheimer's Disease: Overview
666
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...

Equilibrium and Balance
5.1K
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...
