The combined effects of metabolic syndrome and the apolipoprotein E and CYP46 genotypes on the risk of cognitive decline has yet to be determined among Taiwanese Chinese. Two hundred and nine mentally healthy middle-aged and older adults were assessed for metabolic syndrome, cognitive function using the Cognitive Abilities Screening Instrument, Mini-Mental State Examination, ApoE, and CYP46 polymorphisms. There were no differences in cognitive performance, ApoE epsilon4 (ε4) carrier status, or CYP46 genotypes between participants with and those without metabolic syndrome. The ε4 carriers and participants with the AA allele of CYP46 had significantly lower mental manipulation score. Metabolic syndrome and ε4 had synergistic effects on cognitive decline. Therefore, the ε4 carriers and participants with the AA allele of CYP46 have decreased mental manipulation ability. The metabolic syndrome may play a role in subtle cognitive dysfunction in ε4 carriers among Taiwanese Chinese.
在台湾华人中，代谢综合征与载脂蛋白E及CYP46基因多态性对认知功能衰退风险的综合影响尚未明确。对209名心理健康的中老年人进行了代谢综合征评估，使用认知能力筛查工具、简易精神状态检查表评估认知功能，并检测了载脂蛋白E（ApoE）和CYP46基因多态性。患有代谢综合征和未患代谢综合征的参与者在认知表现、ApoE ε4携带者状态或CYP46基因多态性方面并无差异。携带ε4等位基因者和具有CYP46基因AA等位基因的参与者的心理操作得分显著较低。代谢综合征和ε4等位基因对认知衰退具有协同作用。因此，携带ε4等位基因者和具有CYP46基因AA等位基因的参与者心理操作能力下降。代谢综合征可能在台湾华人携带ε4等位基因者的轻微认知功能障碍中起作用。
