据1月7日刊《美国医学协会期刊》(JAMA)上的一则研究披露,罹患晚期帕金森氏病(PD)的患者,在接受深部脑刺激治疗6个月后,比那些接受其它内科治疗的患者在运动技能和生活质量上会有更多的改善,但同时也有较高的出现严重不良反应的风险。深部脑刺激是一种外科治疗手段,它涉及到用植入电极来向脑部的特殊部位发送电刺激以减少不自主的身体运动和颤抖。根据文章的背景资料,当PD的运动性并发症无法用药物进行充分控制的时候,这种治疗就成为首选的外科干预手段。论文写道:“但是,近来的报告突显了该刺激疗法的没有料到的对行为方面的影响,从而表明,深部脑刺激在改善运动功能的同时可能还有 According to a Jan. 7 JAMA study, patients with advanced Parkinson’s disease (PD) reported that after 6 months of deep brain stimulation, patients who received other medical treatments Of patients have more improvement in motor skills and quality of life, but also have a higher risk of serious adverse reactions. Deep brain stimulation is a surgical treatment that involves using implanted electrodes to send electrical stimulation to specific parts of the brain to reduce involuntary physical movements and tremors. According to the article’s background, this treatment is the surgical intervention of choice when the motor complications of PD are not adequately controlled by the drug. The paper writes: ”However, recent reports highlight the unanticipated behavioral effects of the stimulus therapy, suggesting that deep brain stimulation may improve motor function as well as
