Body Mass Index Trajectories Preceding Incident Mild Cognitive Impairment and Dementia

Weili Xu, researcher in the field of Mild Cognitive Impairment and Dementia, talks about the relationship between body mass index and brain health. They discuss previous studies on BMI and Alzheimer's disease, track BMI over time, and explore the association between brain pathology and BMI decline. They also highlight a study suggesting that BMI may decline years before the development of mild cognitive impairment, emphasizing the importance of regularly monitoring weight change among older adults.
