一项新的研究表明,我们口中的1 000亿细菌,即口服微生物,在出现症状之前,可以预测认知下降。 A new study indicates that the 100 billion bacteria in our mouths, known as the oral microbiome, may predict cognitive decline before symptoms occur. 研究人员分析了120名老年人的样本,发现特定类型的细菌与更好的认知测试性能相关,而其他细菌则与轻微认知缺陷相关。 Researchers analyzed samples from 120 older adults and discovered that specific types of bacteria were associated with better cognitive test performance, while others correlated with mild cognitive impairment. 这一调查结果强化了口腔健康与认知健康之间的联系。 This finding reinforces the connection between oral and cognitive health.
