“双高”中年人患老年痴呆症风险同样升高(Whitehall II研究)

2013-03-09 佚名 新华社

  法国科研人员2月21日通过美国神经病学学会发布的一份报告指出,存在高胆固醇、高血压等心血管疾病隐忧的中年人不仅容易患心脏病,而且他们患老年痴呆症(AD)的风险也相应较高。   这项研究由法国国家卫生和医学研究院完成。在研究中,平均年龄55岁的3486名男性和1341名女性在10年内接受了3次认知测试,记录了他们的推理和记忆能力、说话流利程度及词汇量。科研人员还根据受试者的胆固醇水平和其他因素

  法国科研人员2月21日通过美国神经病学学会发布的一份报告指出,存在高胆固醇、高血压等心血管疾病隐忧的中年人不仅容易患心脏病,而且他们患老年痴呆症(AD)的风险也相应较高。   这项研究由法国国家卫生和医学研究院完成。在研究中,平均年龄55岁的3486名男性和1341名女性在10年内接受了3次认知测试,记录了他们的推理和记忆能力、说话流利程度及词汇量。科研人员还根据受试者的胆固醇水平和其他因素,推测其未来10年患心血管疾病的风险数值。   研究人员发现,与患心血管疾病风险较低的人群相比,患病风险较高人群的认知能力相对较低,后者总体认知能力下降的速度也较快。例如,研究对象的未来10年患心血管病风险数值每升高10%,其中的男性记忆测试分数会相应下降2.8%,女性的分数则下降7.1%。研究人员指出,患心血管病的风险高可能导致认知能力下降的成因比较复杂。例如,高血压和高胆固醇容易引起动脉硬化,该病患者得老年痴呆症的几率也较高,但也有可能是其他一些未明原因引起老年痴呆症。 MedSci评: Whitehall II研究从1985年开始,至今已超过28年!目前根据Whitehall II资料挖掘
