更年期女性接受激素疗法可能加速脑萎缩
   美国研究人员最近公布的研究成果表明,广泛应用于更年期女性的激素疗法可能加速脑萎缩。相关研究有维客弗雷斯特大学漫信会医疗中心专家主持。
    研究人员跟踪调查了1400名女性,她们的年龄介于71-89岁,参与激素疗法研究46年。漫信会医疗中心用核磁共振成像仪器扫描患者脑部,发现中老年妇女使用激素疗法后,额叶和海马体的体积萎缩,而这些正是人脑中决定思维记忆能力的关键部位。
    漫信会意料中的研究人员劳拉.库克说:“我们的研究揭示了为什么使用激素疗法的老年妇女更容易罹患老年痴呆症。激素疗法对大脑记忆结构的正常运行有消极影响,对那些使用激素疗法之前就患上思维记忆疾病者影响最显著”研究人员建议患者只在万不得已的情况下使用激素疗法治疗更年期综合征,用药剂量和治疗时间都应控制在最低水平。
