[Pay attention to clinical research, diagnosis and treatment of mixed cognitive impairment].

The concept of mixed cognitive impairment, which was put forward on the basis of mixed dementia, has wider implications. It emphasizes that cognitive impairment has not progressed to the early clinical stages of dementia. In recent years, the focus of dementia research has shifted to the "pre-dementia stage", and more attention has been paid to the influence of vascular factors on cognitive impairment. To a certain extent, vascular risk factors and cerebrovascular diseases can be intervened. Therefore, paying attention to the early clinical identification of mixed cognitive impairment, and strengthening the research and intervention of vascular factors in cognitive impairment has important clinical significance for the effective prevention and treatment of dementia.
