Abstract: Community screening and diagnosis of mild cognitive impairment（MCI）in the community are of great value in the prevention of dementia. Currently，there is still no consensus on the management of community screening and diagnosis in the MCI population. This study conducted a detailed review of the current management of community screening and diagnosis，specific items for screening and diagnosis，and peri-diagnostic support for the MCI population，and found that community screening and diagnosis of MCI need to be comprehensively assessed in terms of population definition，history taking，cognitive assessment and auxiliary testing；peri-diagnostic support should include post-diagnostic disclosure，development of post-diagnostic support program and guidance on post-diagnostic support. Thus，it is suggested that community healthcare workers should carry out comprehensive assessment and diagnosis of the MCI population，and actively carry out rapid post-diagnostic support actions to promote the dementia prevention to be really moved forward.
