What are the determinants of cognitive performance and decline across diverse ethno-regional groups?
Controlling modifiable risk factors such as smoking, diabetes, and physical activity could minimize worldwide cognitive decline, though ethno-regional differences must be considered.
These results suggest that education, smoking, physical activity, diabetes, and stroke are all modifiable factors associated with cognitive decline. If these factors are determined to be causal, controlling them could minimize worldwide levels of cognitive decline. However, any global prevention strategy may need to consider ethno-regional differences.
Lipnicki et al. (2019) studied this question.
