PLoS One:抗血栓药有助缓解老年痴呆症

2014-02-28 佚名 生物360

近日,来自日本国立循环器官疾病研究中心的研究人员调查发现,抗血栓药物西洛他唑(Cilostazol)还具有缓解老年痴呆症的作用。他们将这一发现在线刊登在了近期的《PLOS ONE》期刊上。 西洛他唑是一种用于预防脑梗塞复发的药物,可抑制血小板聚集,扩张血管,改善脑内血流,从而预防血栓形成。老年痴呆症是脑内血管和神经细胞出现障碍,导致记忆力等认知能力下降造成的。 由于很多老年痴呆症患者都并发血管

近日,来自日本国立循环器官疾病研究中心的研究人员调查发现,抗血栓药物西洛他唑(Cilostazol)还具有缓解老年痴呆症的作用。他们将这一发现在线刊登在了近期的《PLOS ONE》期刊上。

西洛他唑是一种用于预防脑梗塞复发的药物,可抑制血小板聚集,扩张血管,改善脑内血流,从而预防血栓形成。老年痴呆症是脑内血管和神经细胞出现障碍,导致记忆力等认知能力下降造成的。

由于很多老年痴呆症患者都并发血管疾病,一些患者也会服用西洛他唑。研究人员调查了 1996 年至 2012 年间的早老性痴呆症患者病历,并且以 30 分为满分,为患者的认知功能打分。

结果发现,在能够勉强维持社会生活的患者中,只服用老年痴呆症药物的 36 名患者一年间认知功能平均下降 2.2 分,而同时服用了西洛他唑的 34 名患者则只平均下降 0.5 分。症状较轻的患者如果服用了西洛他唑,记忆和准确掌握自己所在地点的能力也出现了改善。

此前在动物实验中,研究人员曾发现西洛他唑能够促进脑内积累的废物排出。他们认为,也许是西洛他唑改善了脑内血流,使脑内积存的异常蛋白质排出到外部,从而缓解了老年痴呆症。

研究小组准备今年秋季与更多医疗机构合作,针对轻度认知障碍患者开展临床研究,以进一步确认西洛他唑对老年痴呆症的疗效。
