概括
帕金森病 (PD) 带有冲动控制障碍 (ICD) 的神经影像显示出各种结果. 本研究确定了一个共同的网络,涉及默认模式和皮层下网络,是这些差异的基础.
科学领域:
- 神经成像是一种神经成像.
- 神经学 神经学
- 精神病学是一个精神病学.
背景情况:
- 帕金森病 (PD) 在有关冲动控制障碍 (ICD) 的磁共振成像 (MRI) 发现中表现出显著的异质性.
- 之前对患有ICD的PD的研究已经确定了多种不同的大脑区域,导致缺乏共识.
- 一个统一的网络假设被提出来协调这些不同的发现.
研究的目的:
- 系统地审查现有的MRI研究与ICDs的PD.
- 通过一种新的功能连接网络映射 (FCNM) 技术,与ICD识别PD中受影响的共同神经网络.
- 为了整合和解释神经成像发现的异质性观察到PD与ICDs.
主要方法:
- 进行了结构性和功能性MRI研究的系统文献综述,以ICD治疗PD.
- 使用人类结合体项目 (HCP) 数据集 (n=1,093) 进行网络分析.
- 应用了一种新的FCNM技术来识别共享异常神经网络.
主要成果:
- 分析了19项研究,涉及345名患有PD和ICD的个人和787名患有PD但没有ICD的个人.
- 确定了异常的神经网络,主要涉及默认模式网络 (DMN) 和皮层下网络.
- 特定的DMN区域包括中/下回,前带皮质和角回;尾状核在皮下网络中被确定.
结论:
- 异质神经成像在PD和ICD中发现的异质神经成像结果是由DMN和皮层下网络的共同异常解释的.
- 这些网络功能障碍与自我调节,决策能力受损以及PD患者的冲动性增加有关.
- 这项研究提供了一个网络层面的理解与ICD背后的神经生物学机制PD与ICD,整合多种先前的发现.

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: Treatment
154
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...

Parkinson's Disease: Overview
323
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...
