The relationship of weight change trajectory with medial temporal lobe atrophy in patients with mild Alzheimer’s disease: results from a cohort study

Introduction Weight loss has been described in 20% to 45% of patients with Alzheimer’s disease (AD) and has been associated with adverse outcomes. Various mechanisms for weight loss in AD patients have been proposed, though none has been proven. This study aimed to elucidate a mechanism of weight loss in AD patients by examining the hypothesis that weight loss is associated with medial temporal lobe atrophy (MTA).
