摘要

肌张力障碍是一种运动障碍疾病,其特征是持续或间歇性肌肉收缩,原因是感觉统合失常、皮质可塑性增强以及皮质内抑制功能缺乏。脑深部刺激苍白球内肌(GPi-DBS)可有效治疗肌张力障碍,减少异常神经振荡,改善运动功能。然而,全身感染会严重影响大脑功能,改变脑电波动态和皮质兴奋性。我们假设,接受 DBS 治疗的肌张力障碍患者在从全身感染中恢复的早期会表现出皮质兴奋性改变和脑电波动态变化,因此有必要调整 DBS 参数以防止症状加重。我们建议开展一项为期两年的临床研究,对 15 名接受 DBS 治疗的肌张力障碍患者进行局部场电位(LFP)记录,以评估这一假设。研究将分析大脑活动模式、症状严重程度和感染对神经活动的影响。连续和感染触发的 LFP 记录将为高级分析提供数据,以确定与肌张力障碍症状和感染影响相关的 LFP 模式。这篇论文强调了个性化和动态 DBS 管理的重要性,尤其是在感染后。全身感染会诱发神经炎症,破坏神经回路,增加大脑对 DBS 的敏感性。及时调整 DBS 对减轻过度刺激和优化疗效至关重要。加强感染后护理,包括全面评估和参数调整,对于管理使用 DBS 的肌张力障碍患者至关重要。未来对神经炎症机制及其对神经回路影响的研究将提高我们对全身感染背景下肌张力障碍的认识和治疗水平。

Could systemic infections influence the effectiveness of deep brain stimulation therapy in patients with dystonia?
Dystonia is a movement disorder characterized by sustained or intermittent muscle contractions resulting from aberrant sensory integration, enhanced cortical plasticity, and lack of intracortical inhibition. Deep brain stimulation of the globus pallidus internus (GPi-DBS) effectively treats dystonia, reducing abnormal neural oscillations and improving motor function. However, systemic infections can significantly impact brain function, altering brain wave dynamics and cortical excitability. We hypothesize that dystonia patients treated with DBS exhibit altered cortical excitability and changes in brain wave dynamics during early recovery from systemic infections, necessitating DBS parameters adjustment to prevent symptoms exacerbation. We propose a two-year clinical study involving 15 dystonia patients with DBS capable of local field potential (LFP) recording to evaluate this hypothesis. The study will analyze brain activity patterns, symptom severity and infection impact on neural activity. Continuous and infection-triggered LFP recording will provide data for advanced analysis to identify LFP patterns associated with dystonia symptoms and the effects of infections. This paper underscored the importance of individualized and dynamic DBS management, especially post-infection. Systemic infections can induce neuroinflammation, disrupting neural circuits and increasing brain sensitivity to DBS. Timely DBS adjustments are crucial to mitigate overstimulation and optimize outcomes. Enhanced post-infection care, including thorough evaluations and parameter adjustments, is essential for managing dystonia patients with DBS. Future research into the neuroinflammatory mechanism and their effect on neural circuits will improve our understanding and treatment of dystonia in the context of systemic infections.

期刊介绍: Medical Hypotheses is a forum for ideas in medicine and related biomedical sciences. It will publish interesting and important theoretical papers that foster the diversity and debate upon which the scientific process thrives. The Aims and Scope of Medical Hypotheses are no different now from what was proposed by the founder of the journal, the late Dr David Horrobin. In his introduction to the first issue of the Journal, he asks ''what sorts of papers will be published in Medical Hypotheses? and goes on to answer ''Medical Hypotheses will publish papers which describe theories, ideas which have a great deal of observational support and some hypotheses where experimental support is yet fragmentary''. (Horrobin DF, 1975 Ideas in Biomedical Science: Reasons for the foundation of Medical Hypotheses. Medical Hypotheses Volume 1, Issue 1, January-February 1975, Pages 1-2.). Medical Hypotheses was therefore launched, and still exists today, to give novel, radical new ideas and speculations in medicine open-minded consideration, opening the field to radical hypotheses which would be rejected by most conventional journals. Papers in Medical Hypotheses take a standard scientific form in terms of style, structure and referencing. The journal therefore constitutes a bridge between cutting-edge theory and the mainstream of medical and scientific communication, which ideas must eventually enter if they are to be critiqued and tested against observations.
