In this research, we aim to analyze the association between the fluctuation of body weight and the risk of cognitive decline. Previous studies had shown the relations between body weight fluctuation and cardiovascular risk and its related mortality. However, the kind of relation with cognitive decline is still unknown. Thus, we seek to explore more on the association between body weight and cognitive decline.
