据美国神经科学学会2016年会上的一项新的研究报道显示,Nuvigil可显著提高路易体痴呆患者的总体精神症状,特别是视觉幻觉,躁动和淡漠这些精神症状。

研究人员写道,“路易体痴呆症的共同特点是白天过度嗜睡和视觉幻觉、躁动、冷漠、妄想、抑郁、兴奋和焦虑的神经精神特点。虽然促醒剂可改善路易体痴呆症患者的嗜睡症状,但是目前并没有研究探究促醒剂对患者神经精神特点的作用。”

为了评估Nuvigil(莫达非尼,Cephalon公司)对路易体痴呆相关的神经精神特点的治疗效果,研究人员进行了一项非盲试验研究。该研究共纳入了20名路易体痴呆患者,给予250mg莫达非尼治疗12周。基线时期以及治疗后1、2、3个月后评估患者的神经精神症状。研究参与者的年龄中位数为72岁。

结果发现,莫达非尼治疗后1个月,患者总体神经精神发病率有所改善。总的神经精神量表评分也有所改善,但是变化并没有统计学意义。此外,莫达非尼治疗1个月后患者的视觉幻觉的躁动的症状得到了改善。神经精神量表评分改善最显著的是淡漠,可在患者治疗1、2、3个月后得到改善。而妄想、抑郁、兴奋或焦虑却并未有明显的改善。

最后,研究人员总结道,“莫达非尼治疗可在治疗早期显著改善患者的整体神经精神的发病率、视觉幻觉和躁动。在整个治疗过程中,淡漠的症状可得到持续的改善。我们的初步研究结果表明莫达非尼可改善路易体痴呆的一些神经精神症状。但是对于开放标签的研究结果必须谨慎解释,因为缺乏对照组的研究结果。

Stroke:莫达非尼可以缓解脑卒中后疲劳

脑卒中后疲劳是常见的现象,也因此降低了患者的生活质量。目前的证据干预是有限的,这是第一次安慰剂对照试验来研药物莫达非尼促醒治疗卒中后的疲劳。该试验是随机,双盲,安慰剂对照试验。患者接受400毫克的莫达非尼或安慰剂治疗90天。评估是在参与者开始参与研究,30,90,和180天时完成。主要终点是在90天时的疲劳状况,通过多维疲劳量表-20个全身疲劳域进行测量。次要终点包括疲劳严重程度量表,蒙特利尔认知
