概括
患有尿失禁的帕金森病患者表现出大脑连接的改变. 具体来说,它们在骨和尾骨等区域表现出更强的功能连接性 (FC),可能会影响膀控制.
科学领域:
- 神经科学是一个神经科学.
- 神经学 神经学
- 医疗成像医学成像
背景情况:
- 尿失禁 (UI) 是帕金森病 (PD) 的普遍和衰弱的症状.
- 了解PD中UI的神经基础对于开发向治疗至关重要.
- 以前的研究表明,大脑网络中断可能导致PD患者的UI.
研究的目的:
- 在帕金森病 (PD) 患者中确定尿失禁 (UI) 的神经相关物.
- 为了比较具有UI (UI-PD) 和没有UI (非UI-PD) 的PD患者之间的功能连接 (FC) 模式.
- 调查状,边缘和执行网络连接的潜在差异.
主要方法:
- 利用休息状态功能性磁共振成像 (rsfMRI) 和T1加权 (T1w) 数据来自帕金森氏症进展标志物倡议 (PPMI) 队列中的119名参与者.
- 进行了静止状态FC分析,评估时间共变性与种子区域,包括前带带状回,前带状回和前.
- 在UI-PD (n=32) 和非UI-PD (n=87) 组之间比较了FC模式.
主要成果:
- 与非UI-PD患者相比,UI-PD患者在双边门和右尾状体和右丘脑之间呈现出显著更大的阳性FC (p < 0.01).
- 与非UI-PD组相比,UI-PD组在前带带状和直角之间也表现出更大的负FC (p < 0.01).
- 这些发现表明与PD中的UI相关的明显的FC模式.
结论:
- 患有PD和UI的个体在PD涉及的神经回路内显示了改变的FC,例如门-尾状线路.
- 观察到的连接性差异可能与参与脑膀控制的神经通路有关.
- 这些结果表明,FC模式可以告知和完善帕金森病患者UI的治疗策略.

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
598
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.
