  澳大利亚研究人员7月17日说,一项针对眼部的测试或许可以发现阿尔茨海默氏症、即老年痴呆症的早期症状。

  研究人员当天在法国举行的阿尔茨海默氏症协会国际会议上说,阿尔茨海默氏症不仅会引发人体大脑变化,还能引发眼部改变。

  研究人员先前挑选110名健康人、13名阿尔茨海默氏症患者和13名患有轻度认知障碍、即早期阿尔茨海默氏症的病人为研究对象,拍摄他们的视网膜图像,展开比对。

  比对结果显示,阿尔茨海默氏症患者与其他两类研究人群相比,视网膜部分血管的宽度不同。

  美联社报道,全球有3500万阿尔茨海默氏症患者。这一病症尚无治愈良方,只能使用药物暂时缓解症状。因此,提早发现患病趋势有助病人家属做好心理准备,安排看护事宜。

  一些研究人员说,脑部扫描可在患者发病前10年甚至更长时间发现阿尔茨海默氏症的迹象。但这一检测方式过于昂贵,无法推广至例行检查中。

  先前从事关联研究的美国波士顿大学教授戈尔德施泰因·李说,这一研究成果“具提示作用、令人鼓舞”。他说,研究人员在脑部以外领域寻找阿尔茨海默氏症的发病证据,“我要向他们脱帽致敬”。
