Abstract: With the emergence of an aging population,chronic diseases seriously affect human health.Alzheimer’s disease （AD）,the most common type of senile dementia,has become a serious threat to the mental health and quality of life of the elderly worldwide.As there is no effective curing ways of this disease and its prognosis is poor,early detection,diagnosis and intervention are particularly important.Good community management of the disease can not only delay the disease process,improve disease prognosis,but also can further reduce our burden of family and society.Subjective cognitive decline （SCD） as a pre-clinical stage of AD has caused widespread attention from medical workers both at home and abroad,but there are few studies on community standardized management of this stage internationally and no researches domestically.Intending to review the community management system of SCD,the paper hopes to provide references for establishing guidance on community management of preclinical phase of AD in China.

摘要： 随着人口老龄化的出现，慢性病严重影响着人类健康，阿尔茨海默病（AD）作为老年痴呆的最常见类型，已经成为严重威胁全球老年人精神健康和生活质量的疾病。鉴于该病无有效治愈手段、预后差，因此早期发现、诊断并干预尤为重要。做好该病的社区管理工作，不仅能延缓疾病进程，改善疾病预后，更能进一步减轻我国的家庭及社会负担。主观认知下降（SCD）作为AD临床前期阶段而引起国内外医学工作者的广泛重视，但是国际上对于该阶段的社区规范化管理研究较少，国内研究更是空白。本文拟通过对SCD的社区管理予以综述，以期为我国AD临床前期SCD社区管理规范的制定提供参考。
