概括
老年人的基本震 (ET) 与显著的认知能力下降有关,特别是在注意力,记忆力和口语流方面. 在ET的认知障碍随着发病年龄和的严重程度而变化,这表明潜在的网络变化.
科学领域:
- 神经科学是一个神经科学.
- 老年学是一门学科.
- 神经学 神经学
背景情况:
- 基本震 (ET) 越来越多地被认为涉及超出运动症状的认知功能障碍.
- 导致ET认知变化的确切病理机制尚不清楚,特别是在老年人群中.
研究的目的:
- 评估老年患有基本震 (ET) 的患者认知变化的特征.
- 研究ET发病年龄,震严重程度和认知功能之间的关系.
- 在ET患者中探索休息状态网络 (RSN) 的功能连接.
主要方法:
- 认知功能使用阿登布鲁克认知检查修订 (ACE-R) 评估了85名老年ET患者 (≥65岁) 没有痴呆症,并与健康对照者 (HCs) 相比.
- 分析了发病时的年龄和震严重程度的相关性.
- 对一组患者进行了休息状态网络 (RSN) 分析,以比较功能连接 (FC) 与年龄匹配的对照组.
主要成果:
- 与HC相比,老年ET患者的ACE-R总得分和注意力,言语流性和记忆力缺陷明显较低.
- 认知功能障碍在老年开始的ET患者中更为明显.
- 语言流性与震严重程度有显著的相关性.
- 额叶语言网络中的功能连接 (FC) 增加在ET患者中与HC患者相比观察到.
结论:
- 患有ET的老年人表现出显著的认知功能障碍,受发病年龄和震严重程度的影响.
- 研究结果表明,ET的病理机制可能涉及类似于早期阿尔茨海默病的网络变化.
- 认知评估和网络分析对于理解ET的全部影响至关重要.

Parkinson's Disease: Treatment
216
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.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Alzheimer's Disease: Overview
444
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...
