Parkinson's Disease: Treatment

281
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

567
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...

科学领域:

  • 神经科学是一个神经科学.
  • 运动障碍 运动障碍
  • 生物医学工程 生物医学工程

背景情况:

  • 帕金森病 (PD) 影响运动控制,步态结 (FOG) 是一个使人虚弱的症状.
  • 了解在PD中像骑自行车一样保存的运动能力对于开发有效疗法至关重要.
  • 之前的研究表明,骑自行车可以通过抑制亚thalamic核 (STN) 的β振荡来增强运动持续性.

研究的目的:

  • 研究主动和被动循环对PD患者STN神经活动的影响.
  • 为了比较患有FOG和没有FOG的患者之间的这些影响.
  • 确定骑自行车时感官输入在调节大脑活动中的作用.

主要方法:

  • 从STN记录了12名PD患者的局部现场潜力 (LFPs) (6名有FOG,6名没有FOG).
  • 贝塔 (13-30 Hz) 和高马 (60-100 Hz) 功率在各种节奏的积极和被动循环过程中被分析.
  • 被动循环使用电机驱动的设置来隔离传感输入效应.

主要成果:

  • 积极和被动循环都显著抑制了病理性β活性.
  • 与被动自行车相比,积极自行车显示高马波段活动增加.
  • 在FOG患者中,β抑制更为明显,特别是在被动循环期间.
  • 节奏没有影响骑自行车对神经活动的观察到的影响.

结论:

  • 循环期间的自身感受输入与PD中的β波抑制有关.
  • 持续的外部感官输入和来自节奏循环的自身感知反有助于运动控制.
  • 通过骑自行车进行系统的被动动化可以为PD患者提供治疗益处,特别是那些患有FOG的患者.
