摘要 目的研究甲状腺激素(TH)在老年人轻度认知障碍(MCI)中的意义,探讨激素分泌异常在MCI发病中的作用。方法用放免方法测定老年52例MCI患者和52例正常对照者的血清游离三碘甲状腺原氨酸(FT3)、血清游离甲状腺激素(FT4)、促甲状腺素(TSH)、甲状腺球蛋白抗体(TGAb)、甲状腺微粒体抗体(TMAb)水平,并用简易智能精神状态量表(MMSE)进行临床智能精神检查评分。结果与对照组相比,老年MCI组患者血清FT3或FT4下降,而TSH、TGAb、TMAb升高(P<0.05),且给予甲状腺激素6个月治疗后,MMSE测试中MCI组治疗后与治疗前比较,差异有统计学意义(P<0.05),日常生活能力量表(ADL)和汉密尔顿抑郁量表17项版(HAMD)测试中MCI组治疗后与对照组比较差异无统计学意义(P>0.05),提示老年MCI组患者的认知功能有所改善。结论甲状腺激素分泌异常是老年认知障碍的重要发病因素,甲状腺激素替代治疗可在一定程度上改善老年亚临床甲状腺功能减退导致的认知功能障碍。
