概括

对帕金森病的自适应性深度大脑刺激 (aDBS) 受刺激和药物的影响. 在现实世界条件下,下核β振荡的预测不那么准确.

科学领域:

神经科学是一个神经科学.
生物医学工程生物医学工程
运动障碍运动障碍

背景情况:

适应性深度大脑刺激 (aDBS) 旨在提高帕金森病 (PD) 的治疗效果,使用亚thalamic 核 (STN) 贝塔波段振荡作为生物标志物.
以前对STNβ振荡的验证往往发生在非真实世界的条件下 (非药物,非刺激).

研究的目的:

为了研究多巴胺作用药物和深度大脑刺激 (DBS) 如何影响STNβ振荡活性.
评估STNβ振荡在不同条件下预测低动力帕金森状态的可靠性.

主要方法:

研究了在活跃DBS期间残留运动波动的6名PD患者的STNβ振荡功率的药物周期诱导的波动.
分析了非药物状态的β振荡大小,峰值频率和预测能力.
在诊所和自然主义家庭药物循环期间收集的神经信号.

主要成果:

与治疗DBS相比,与DBS关闭时相比,药物诱导的β振荡波动显着较小 (P=0.008).
治疗性刺激降低了贝塔活动的峰值频率 (P<0.001).
在非药物/非刺激状态下预测最佳的β频率在活性刺激期间不太准确 (P=0.02).

结论:

通过刺激和药物治疗,STNβ振荡的光谱特征会发生变化.
作为帕金森病中aDBS的生物标志物,STNβ振荡的有效性取决于病情.
研究结果强调需要考虑现实世界的刺激和药物效应,以便在适应性DBS中准确地应用生物标志物.

Parkinson's Disease: Treatment

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...

Neural Regulation

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.

Parkinson's Disease: Overview

Parkinson's Disease: Overview

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...
