Effectiveness of an Innovative Therapeutic Exercise Program on Physical and Cognitive Function in Mild Cognitive Impairment Due to Alzheimer's Disease

The goal of this randomised clinical trial is to investigate the effectiveness of an innovative therapeutic exercise program emphasizing in dual-task exercises in people with amnestic Mild Cognitive Impairment. The main questions it aims to answer are: Does the innovative therapeutic exercise program improve gait and balance? Does the innovative therapeutic exercise program improve cognition? Researchers will compare the innovative therapeutic exercise program emphasizing in dual-task exercises to a therapeutic exercise program without emphasizing in dual-task exercises and to a control group (given instruction about the benefits of exercise). Participants will: * Perform the exercise program twice a week for three months. * Will be assessed before and after the intervention. * Will record The Borg Scale of Perceived Exertion every second week to monitor and assess the progression of exercise intensity.
