概括
脊椎巴性 dolichoectasia (VBD) 在帕金森病 (PD) 患者中更为常见. 在PD中,VBD与广泛的白质损伤和网络中断有关,影响运动和非运动功能.
科学领域:
- 神经学 神经学
- 神经成像是一种神经成像.
- 神经科学是一个神经科学.
背景情况:
- 帕金森病 (PD) 是一种神经退行性疾病.
- 脊椎骨性多利科埃克塔西亚 (VBD) 涉及脊椎骨动脉的异常扩大和延长.
- 在VBD和PD病理生理学之间的关系仍然不清楚.
研究的目的:
- 为了确定帕金森病 (PD) 患者中VBD的患病率.
- 调查VBD对灰质,白质 (WM) 微观结构和PD网络变化的影响.
主要方法:
- 341名PD患者的横截面研究.
- 与一般人口的VBD患病率的比较.
- 在174名PD患者中,扩散张力成像 (DTI) 和T1加权成像用于WM和灰质分析.
- 进行了基于voxel的形态测量,基于通道的空间统计 (TBSS),感兴趣区域 (ROI) 分析和WM网络分析.
主要成果:
- 与普通人群相比,PD患者的VBD患病率明显高于PD患者.
- 患有VBD的PD患者显示,在广泛的WM区域中,分数异构性 (FA) 降低,扩散性增加,没有显著的灰质变化.
- WM网络分析显示,全球和地方效率下降,层次层次增加,以及VDBDPD患者的中心性指标发生变化.
结论:
- 在PD患者中,VBD更为普遍.
- 在PD患者中,VBD与更明显的白质微观结构和网络损伤有关,影响与运动和非运动症状相关的区域.

Parkinson's Disease: Overview
527
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.
