Cognitive decline may progress to cognitive impairment
Machine learning techniques help reveal potential associations between research factors and outcomes [4]
In August 2022, the team of Associate Professor Zeng Yanbing of Capital Medical University and the team of Tencent Tianyan Laboratory published an article entitled "Using machine learning algorithms for predicting cognitive impairment and identifying modifiable factors among Chinese elderly people" on Frontiers in Aging Neuroscience, proposing developed a predictive model of cognitive impairment risk and explored the impact of behavioral changes on cognitive impairment
First, to provide an early predictor of the risk of developing cognitive impairment, the authors used CLHLS data from 2002 to 2014, incorporating sociodemographic information, psychological status, lifestyle, social/recreational activities, and activities of daily living.

In addition to unchangeable factors, researchers also focused on the relationship between longitudinal behavioral changes and changes in the types of activities involved and cognitive impairment in order to better serve policy management and intervention

These findings have potential public health implications for the health of older adults and could aid in the development of new tools , for early identification in the community, especially for the relatively young elderly population and the current cognitively normal elderly population
.
In addition, this study also suggests that modifiable behaviors such as doing more leisure activities, gardening, and participating in various activities can reduce the risk of cognitive impairment
.
There are some shortcomings in this study.
For example, similar to other studies, the researchers excluded the population with MMSE deletion [7,8], but the reason for the deletion could not be determined, it may be due to severe cognitive impairment, so there may be Select Offset
.
Additionally, although the study was based on data from 4 surveys and used a cross-validation approach, the results need to be validated in another cohort
