概括
与健康对照人群相比,基本震 (ET) 患者在认知功能中增加了个体内变异性 (IIV-D),即使没有正式诊断. 这一发现突显了ET中潜在的神经学差异,表明IIV-D是关键标志物.
科学领域:
- 神经科学是一个神经科学.
- 认知心理学 认知心理学
- 神经学 神经学
背景情况:
- 在基本震 (ET) 中,认知能力下降可能比以前理解的更为常见.
- 基于分散的个体内变异性 (IIV-D) 是一种关于神经完整性的指标.
- 在帕金森病 (PD) 中记录了升高的IIV-D,但尚未在ET中进行研究.
研究的目的:
- 研究ET患者的认知功能和IIV-D.
- 为了比较ET,PD和认知完整的对照 (IC) 之间的认知表现和IIV-D.
主要方法:
- 对188名PD,53名ET和135名IC患者的神经心理数据的回顾性分析.
- 在13个神经认知得分中使用个体内标准偏差 (iSD) 和方差系数 (CoV) 计算IIV-D.
- 在"没有认知障碍" (NCD) 的参与者小组中对IIV-D进行二次分析.
主要成果:
- 在处理速度,心理跟踪,设置转移和语义流性方面,PD和ET组的表现都比IC差.
- 在使用Cov.时,与IC相比,在PD和ET中观察到更大的IIV-D.
- 患有ET的个体在使用Cov.时表现出比IC更大的IIV-D,即使在NCD子集中,也表现出更大的IIV-D.
结论:
- 这项研究是首次在与对照人群相比,与ET患者相比,首次证明ET患者的IIV-D增加,而不管他们是否有正式的神经认知诊断.
- 研究结果表明,IIV-D可以作为ET的认知改变的有价值标志物.
- 需要进一步的研究来探索潜在的临床混,如药物和运动严重程度.

Parkinson's Disease: Overview
723
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

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.

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.
