概括

神经元α-synuclein疾病综合分期系统 (NSD-ISS) 在早期阶段有效追踪疾病进展超过五年. 这种分阶段系统显示出作为开发神经退行性疾病新治疗方法的研究工具的前景.

科学领域:

神经学神经学
生物标志物研究的研究.
神经退行性疾病研究

背景情况:

神经元α-synuclein疾病 (NSD) 的特征在于神经元α-synuclein (n-asyn) 病理的体内生物标志物.
神经元α-synuclein疾病综合分期系统 (NSD-ISS) 将疾病进展从0到6阶段分类.

研究的目的:

评估NSD-ISS在早期疾病中的5年纵向变化.
评估NSD-ISS在跟踪帕金森病 (PD) 患者,先发性PD患者和健康对照 (HC) 患者的疾病进展中的实用性.

主要方法:

对符合NSD标准的帕金森氏症进展标记计划 (PPMI) 参与者的子集进行分析.
根据n-asyn生物标志物,多巴胺功能障碍,临床特征和功能障碍,每年分阶段超过5年.
包括在2020年之前注册的PD患者,前发性PD患者和HC.

主要成果:

在基线时,大多数参与者处于2B (24%),3 (56%) 或4 (13%).
5年后,阶段分布发生了转变,在第3阶段 (50%) 和第4阶段 (34%) 的百分比增加,表明进展.
进展驱动因素包括运动和非运动功能障碍,多巴胺类药物开始导致一些参与者的阶段回归.

结论:

NSD-ISS对于定义早期疾病进展 (2B,3,4阶段) 非常有价值,并作为药物开发的潜在研究工具.
建议对临床前队列进行进一步的研究,以完全确定NSD-ISS.
这项研究支持NSD-ISS在对帕金森病等神经退行性疾病的研究中的实用性.

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.

Parkinson's Disease: Overview

Parkinson's Disease: Overview

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...

Alzheimer's Disease: Overview

Alzheimer's Disease: Overview

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...
