概括
低频次亚thalamic核刺激 (LFS) 改善了帕金森病 (PD) 患者的言语与步行问题,与高频率刺激 (HFS) 不同. 不对称刺激也显示出好处,这表明PD语言功能障碍的量身定制方法.
科学领域:
- 神经学 神经学
- 神经外科 神经外科
- 语音科学 语言科学
背景情况:
- 双边高频下丘脑核刺激 (Bi-HFS) 往往会在帕金森病 (PD) 中加剧语言问题.
- 低频刺激 (LFS) 显示出改善步态的潜力,但缺乏关于PD语音益处的有力证据.
研究的目的:
- 为了比较双边低频刺激 (Bi-LFS) 和Bi-HFS对PD患者与姿势不稳定和步行困难 (PIGD) 的言语的影响.
- 为了评估PD患者的非对称频率刺激 (AFS).
主要方法:
- 随机试验涉及33名患有PIGD的PD患者,比较Bi-LFS (60Hz) 和Bi-HFS (130Hz).
- 在20名PD患者中评估非对称频率刺激 (AFS),包括左侧LFS/右侧HFS (L-LFS/R-HFS).
- 使用失声严重程度指数 (DSI) 和最大发音时间 (MPT),以及主观评分来评估语音.
主要成果:
- 与Bi-HFS相比,Bi-LFS显著改善了DSI (FDR-p=0.024) 和MPT (FDR-p=0.025) 的情况.
- 在客观语音测量方面,AFS,特别是L-LFS/R-HFS,在客观语音测量方面表现出与Bi-LFS相当的有效性,并且优于Bi-HFS (FDR-p ≤0.021).
- 语音的改善与运动和步态的改善相关,不论震的严重程度如何.
结论:
- 双LFS有效地减轻了PIGD-PD患者的语言功能障碍.
- 左侧LFS可能是语音改善的关键因素,而AFS提供了类似的好处.
- 这些发现支持开发个性化的刺激协议,以优化帕金森病的语音结果.

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.
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
710
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...

Neural Regulation

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.
