概括
情绪性听觉刺激会影响帕金森病 (PD) 中的步行启动与步行结 (FOG). 不愉快的声音恶化了步态控制,而愉快的声音改善了它,这表明边缘系统参与FOG.
科学领域:
- 神经科学是一个神经科学.
- 运动障碍 运动障碍
- 心理学 心理学 心理学
背景情况:
- 在帕金森病 (PD) 中,步态结 (FOG) 受感官,认知和边缘因素的影响.
- 边缘系统在FOG中的作用与情绪负载有关,可能会从运动控制中转移认知资源.
- 之前的研究发现,情感视觉刺激对FOG的PD患者的步态调整没有影响.
研究的目的:
- 研究具有情感内容的生态听觉刺激对FOG和没有FOG的PD患者步行启动的影响.
- 为了比较中性,愉快和不愉快的听觉刺激对步骤启动参数的影响.
主要方法:
- 45名参与者 (15名有FOG的PD,15名没有FOG的PD,15名健康对照) 进行了前进步骤启动任务.
- 参与者在站在强力平台上时对中性,愉快或不愉快的听觉刺激做出了反应.
- 分析了预期的姿势调整和压力中心 (CoP) 位移.
主要成果:
- 患有FOG的PD患者在不愉快的听觉刺激后表现出减少的CoP位移,并在愉快的刺激后促进了位移.
- 健康的对照组和没有FOG的PD患者在对情感刺激的反应中没有显著改变COP位移.
- 边缘系统的参与,特别是抑郁症,与FOG的PD的改变行为反应有关.
结论:
- 具有情绪价值的听觉刺激显著调节FOG的PD患者的步行启动.
- 这些发现突出了情绪网络的关键作用,以及它对FOG病理生理学的注意力资源的干扰.
- 这表明,情绪处理直接影响FOG患者的运动控制.

Parkinson's Disease: Treatment
220
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: Overview
482
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...

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.
