Effect of Scene-Based Training on Cognitive Function in Patients With Alzheimer's Disease

Summary

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline, including impairments in orientation, memory, and daily functioning. Orientation dysfunction, involving difficulties in recognizing time, place, and person, is a common and clinically significant feature in patients with mild to moderate AD.

This study aims to evaluate the effectiveness of a scenario-based reenactment training program in improving cognitive function and orientation ability in patients with mild to moderate Alzheimer's disease. The intervention is based on patients' real-life experiences and uses personalized visual materials (e.g., photos and videos) to reconstruct familiar scenarios, thereby enhancing cognitive stimulation and environmental recognition.

In this prospective controlled study, participants will be assigned to either a scenario-based training group or a usual care group. The intervention group will receive structured training sessions three times per week for 3 months, followed by a 6-month follow-up period. The control group will receive standard care without structured cognitive training.

The primary outcome is global cognitive function assessed by the Montreal Cognitive Assessment (MoCA). Secondary outcomes include orientation function, depressive symptoms, anxiety levels, quality of life, and intervention feasibility. This study aims to provide evidence for a practical, non-pharmacological intervention to improve cognitive and functional outcomes in patients with Alzheimer's disease.

Scenario-Based Reenactment Training

Scenario-based reenactment training is a structured, personalized cognitive intervention designed to improve orientation and cognitive function in patients with Alzheimer's disease. The intervention is based on patients' real-life experiences and utilizes individualized visual materials, such as photographs and videos, to reconstruct familiar temporal, spatial, and interpersonal scenarios. Participants engage in guided recognition, recall, and contextual judgment tasks targeting orientation domains (time, place, and person). The intervention is delivered three times per week for 3 months, with each session lasting approximately 30-45 minutes. Training is conducted by trained healthcare providers or caregivers, both in hospital and home settings, with ongoing supervision to ensure consistency and adherence.

OTHER

Usual Care

Participants receive standard medical and nursing care without structured cognitive intervention. Routine care includes pharmacological treatment, basic nursing support, and general health education.
