About

This study is a multicentre, randomized, double-blind, controlled trial that aims to investigate the efficacy of multi-domain life-style intervention including low inflammatory-index diet, exercise, and cognitive training in patients with mild cognitive impairment and mild Alzheimer's disease.

Full description

This is a multicentre, randomized, double-blind, controlled trial that aims to investigate the efficacy of multi-domain life-style intervention including low inflammatory-index diet, exercise, and cognitive training in patients with mild cognitive impairment and mild Alzheimer's disease. Patients who eligible to the inclusion criteria and ineligible to the exclusion criteria will be randomly assigned into three groups by a 1:1:1 ratio. Patients in first arm will receive multi-domain life-style intervention including low inflammatory-index diet, exercise, and cognitive training. Patients in the second arm will receive intervention of exercise and cognitive training. Patients in the third arm will receive regular health advice. We hypothesize that the multi-domain intervention will reduce impairment in the study group compared to the control group during the 2-year intervention period.
