概括
将跨直流刺激 (tDCS) 与虚拟现实 (VR) 康复相结合,可促进中风患者的持续运动恢复. 这种方法可以抵消甲状腺皮层节律失常,增强大脑网络参与度,以获得长期益处.
科学领域:
- 神经科学是一个神经科学.
- 康复医学 康复医学 康复医学
- 生物医学工程 生物医学工程
背景情况:
- 脑卒中康复治疗往往无法确保在治疗期间以外的持续恢复.
- 甲状腺皮质节律失常 (TCD),以扰乱阿尔法节律为特征,在中风患者中很常见,但其功能影响仍然不清楚.
- 了解持续恢复的机制对于改善中风后的结果至关重要.
研究的目的:
- 研究将焦点运动皮层刺激与虚拟现实 (VR) 康复相结合是否可以抵消TCD,并促进中风患者的持续运动恢复.
- 探索跨直流刺激 (tDCS) 在调节甲状腺皮层节律和增强康复结果方面的作用.
- 确定阿尔法节律变化与中风后行为恢复之间的相关性.
主要方法:
- 一项涉及中风患者进行基于VR的康复 (康复游戏系统 (RGS)) 的比较研究.
- 干预组接受了运动皮层的双边tDCS或假刺激.
- 评估了脑皮层节律和临床尺度,以评估运动恢复和大脑活动.
主要成果:
- 接受tDCS增强VR康复的患者在治疗后3个月内在所有临床尺度上表现出持续改善,与假装组不同.
- 超直流刺激 (tDCS) 有效地抵消阿尔法节律的减缓,特别是通过增强 parietal 区域的刺激性.
- 在阿尔法节律的变化和运动恢复程度之间没有发现显著的相关性.
结论:
- 用tDCS增强的基于VR的康复是一种有前途的策略,可以促进中风患者的持续康复.
- 调节头顶区域兴奋度和参与目标导向的大脑网络可以抵消TCD,有助于改善康复结果.
- 虽然观察到TCD对抗作用,但在这种情况下,TCD可能不是持续运动恢复的主要驱动因素.

Alzheimer's Disease: Treatment
1.3K
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Ischemic Stroke l: Introduction
57
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
