科学家发现脊髓刺激可改善卒中后手臂活动能力
脊髓刺激 卒中 手臂活动能力
2024/1/17
脑卒中会破坏运动皮质区域发送给脊髓的下行指令，从而导致手臂和手部的永久性运动缺陷。然而，由于脑卒中属于上运动神经元损伤，故位于损伤下方，控制运动的颈椎脊髓回路仍保持完整，并可能通过神经外科技术恢复运动能力。近期，来自匹兹堡大学和卡内基梅隆大学等机构的研究人员发现，一种称为硬膜外电刺激的神经外科技术，可以增强卒中后偏瘫患者的手臂和手部活动能力，这是该技术首次被应用到卒中患者体内。研究成果发表在《Na...

研究揭示抗凝栓药或增加脑出血几率
抗凝栓药 硬脑膜下血肿 发生率
2017/3/2
近日，一项新研究发现，抗凝栓药的使用或能改变硬脑膜下血肿的发生率。这些抗凝栓药物包括低剂量阿司匹林、维生素K拮抗剂（如华法林）、氯吡格雷及口服抗凝药等。相关论文刊登于《美国医学会杂志》。丹麦大学的David Gaist及同事分析了10010位硬脑膜下血肿患者以及40多万名对照组人员的数据。实验组参与者的年龄为20至89岁，他们在2000年至2015年第一次出现硬膜下血肿，其中有47%的人在服用抗凝...
