In a 2016 study by Giuli and colleagues, 321 adults were divided into three groups: people with mild to moderate Alzheimer's, people with mild cognitive impairment (MCI), and people without cognitive decline. The comprehensive intervention included a combination of rehabilitation (cognitive training), compensation (strategies), a healthy lifestyle, and psychological support. The authors found a significant improvement in all three groups compared to adults who didn't exercise. In addition, there was an improvement in auditory verbal memory tasks and subjective complaints about memory impairment among adults with mild cognitive impairment (MCI). A significant decrease in s
ubjective complaints was observed in adults without cognitive decline. These results show that cognitive training improves memory and functioning in adults with and without cognitive decline.
