晚期脑损伤使痴呆风险增加高达69%,主要原因下降,特别是对脆弱地区的老年妇女而言。 Late-life brain injuries raise dementia risk by up to 69%, with falls the main cause, especially for older women in vulnerable areas.

加拿大对超过260,000名65岁和65岁以上的成年人进行的一项研究发现,创伤性脑损伤(TTI)与5年内69%的痴呆症风险有关,超过56%的增加是主要原因,而下降是主要原因。 A Canadian study of over 260,000 adults aged 65 and older found that traumatic brain injuries (TBI) are linked to a 69% higher dementia risk within five years and a 56% increase beyond that, with falls being the leading cause. TBI病人还更多地使用家庭护理,并更有可能接受长期护理。 TBI patients also used more home care and were more likely to enter long-term care. 较高风险与老年、女性性别、低收入、较小社区以及族裔多样性较低有关。 Higher risks were tied to older age, female sex, low income, smaller communities, and lower ethnic diversity. 研究结果强调了预防跌倒的必要性，特别是对于脆弱地区的 75 岁及以上女性，并强调即使在晚年 TBI 之后也存在长期痴呆风险。 The findings stress the need for fall prevention, especially for women 75 and older in vulnerable areas, and highlight long-term dementia risks even after late-life TBI.
