研究的目的:

在早期帕金森病 (PD) 中识别临床相关的认知亚型.
将神经心理学概况与通过视觉MRI尺度评估的区域大脑缩在新发病患者中的神经心理学概况整合起来.

主要方法:

一项涉及81名新发帕金森病 (PD) 患者和20名健康对照者的横截面研究.
使用3TMRI,视力缩评级和广泛的神经心理学电池.
采用混合的先验后验方法来定义解剖认知亚型.

主要成果:

定义了八种解剖认知亚型,反映了前下皮层,后皮层,海马,全球和保存的认知模式.
特定的MRI标记与执行,视觉空间,记忆和语言领域的认知缺陷相关.
集群分析证实了确定的亚型的有效性 (AUC范围:0.68-0.95).

结论:

这项研究提出了一种实际的分类模型,将认知表现与早期帕金森病 (PD) 中的结构性大脑变化联系起来.
这种可扩展的方法可以增强早期患者分层,并为个性化管理策略提供信息.

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...

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.
