Differential brain volume between obese and underweight cognitively normal older adults with frailty in the JPSC-AD

Differential brain volume between obese and underweight cognitively normal older adults with frailty in the JPSC-AD

Abstract Frailty is common in older adults; however, the central nervous system mechanisms underlying the differences between obesity and underweight remain unclear. This study investigated brain volume in frail, cognitively normal, community-dwelling older adults across three body mass index (BMI)...
