Among those aged 80 years and older in Ontario, Canada, stroke and dementia incidence declined concomitantly from 2002-03 to 2013-14. This study aimed to report the concurrent temporal trends of stroke and dementia prevalence in Ontario among the same age demographic. The prevalence of both stroke and dementia increased from 2003-04 to 2012-13 in both sexes and the magnitude in which prevalence of dementia increased over time exceeded that of stroke. The substantial increase in the prevalence of dementia may be because of increased recognition and diagnoses of dementia and increased survival of stroke patients who are at higher risk of developing dementia.
在加拿大安大略省 80 岁及以上的人群中,2002-03 年至 2013-14 年期间,中风和痴呆的发病率同时下降。本研究旨在报告安大略省同一年龄组人群中风和痴呆患病率的同时期趋势。在男性和女性中,2003-04 年至 2012-13 年期间,中风和痴呆的患病率均有所增加,而且随着时间的推移,痴呆的患病率增加幅度超过了中风。痴呆症患病率的大幅增加可能是由于对痴呆症的认识和诊断增加,以及处于更高痴呆风险的中风患者的存活率增加所致。
