BACKGROUND
The purpose of this study was to update the previous estimate of the worldwide cost of dementia in 2005 to 2009.
METHODS
The cost model is based on prevalence estimates, country and region-specific data on Gross Domestic Product per person and average wage, with results from previously published cost-of-illness studies in different countries. Prevalence figures are updated to 2009 and costs were adjusted to 2009 constant US dollars ($).
RESULTS
The total worldwide societal cost of dementia, based on a dementia population of 34.4 million demented persons, was estimated to $422 billion in 2009, including $142 billion for informal care (34%).
CONCLUSIONS
The worldwide cost of dementia has increased by 34% (18% in fixed prices) between 2005 and 2009.
背景
本研究旨在更新 2005 年至 2009 年全球痴呆症成本的先前估计。
方法
该成本模型基于患病率估计、人均国内生产总值和平均工资的国家和地区特定数据，并结合了不同国家先前发表的疾病成本研究结果。患病率数据更新至 2009 年，成本根据 2009 年不变的美元（$）进行调整。
结果
基于 3440 万痴呆患者的痴呆人口，2009 年全球痴呆症的社会总成本估计为 4220 亿美元，其中包括 1420 亿美元的非正式护理（34%）。
结论
2005 年至 2009 年间，全球痴呆症成本增加了 34%（固定价格下增加了 18%）。
