The control group will not participate in the physical or cognitive exercise intervention but will receive general recommendations for comprehensive health care. This includes discussions about the benefits of engaging in physical and cognitive exercise, as well as advice on managing physical and mental health. All proposed physical and mental assessments will be conducted with the control group at the beginning of the study and after 12 weeks. Additionally, during the study period, they will be monitored for any changes in physical activity levels that may occur throughout the intervention. Follow-up will also include tracking nutritional changes, sleep habits, and stress levels.

The intervention for the experimental group implements a digital and interactive reminiscence program, starting with a preparation phase to select participants based on predefined criteria. Personalized content is developed for each individual, creating digital profiles that include photographs, music, videos, and significant life anecdotes tailored to evoke emotional memories. Care staff receive training on using the software and reminiscence techniques to facilitate the intervention. The implementation phase includes group and individual digital reminiscence sessions held twice a week for eight weeks, lasting about 60 minutes each. These sessions present selected digital content to promote discussion and memory sharing. Interactive activities, such as games and exercises, foster active participation, while the facilitator encourages participants to share stories and emotions, creating a supportive environment.

The intervention for the experimental group aims to enhance the psychological well-being of institutionalized seniors with Alzheimer's through a digital and interactive reminiscence therapy program. It begins with selecting participants based on specific inclusion and exclusion criteria, followed by developing personalized digital profiles that include photographs, music, videos, and life anecdotes to evoke emotional memories. Care staff receive training in using the digital software and reminiscence techniques. The core intervention consists of digital reminiscence sessions held twice a week for eight weeks, lasting about 60 minutes each, featuring multimedia content to encourage discussion and memory sharing. Interactive activities foster active participation, with facilitators promoting emotional expression and connection among participants, creating a supportive environment that stimulates cognitive function and reduces isolation.

This Scale is a 13-item tool that measures quality of life specifically in people with Alzheimer's. Each item is scored from 1 to 4, with a higher score indicating a better perception of quality of life. Areas assessed include mood, physical well-being, relationships, and environment. A high total score suggests a positive perception of quality of life, useful for assessing the impact of psychological and therapeutic interventions.

The most widely used cognitive screening test to assess suspected symptoms consistent with cognitive impairment or dementia. Written test with a maximum score of 30. The cut-off point established for the MMSE defines "normal" cognitive function is generally set at 24, lower scores indicate more serious cognitive problems.

Instrument that examines the skills of attention, concentration, executive functions, memory, language, visuoconstructive abilities, calculation and orientation and the maximum score is 30.

It is used to assess executive function. It measures timed motor and visual tasks, and is divided into two tests: Part A (TMTA), which assesses speed and psychomotor attention and requires connecting consecutively numbered circles; and Part B (TMTB), which tests executive function and requires connecting alternating circles of numbers and letters. Longer completion times indicate poor performance.

Instrument used to assess verbal fluency. Participants have 60 seconds to generate as many words as possible within a given semantic category (animals, colors, fruits, and cities). The maximum score is 40 points (with a maximum of 10 per category). The higher the score, the better the level of verbal fluency.Instrument used to assess verbal fluency.
