一项新的欧洲研究发现,70岁以下病人的甲状腺纤维化(AFib)会增加21%的痴呆风险,并会增加36%的早发性痴呆风险。 A new European study found that atrial fibrillation (AFib) increases the risk of dementia by 21% in patients under 70 and raises early-onset dementia risk by 36%. 这项涉及250多万人的研究显示,年青病人的AFib和痴呆症之间的联系更加密切,随着年龄的增长,这种联系越来越弱。 The study, involving over 2.5 million people, showed a stronger link between AFib and dementia in younger patients, with the association weakening as age increased. 研究人员认为,AFib可能是年轻成人认知下降的一个主要因素。 Researchers suggest AFib may be a primary factor in cognitive decline for younger adults.
