Summary

This randomized controlled clinical trial aims to evaluate the effectiveness of dual-task training on cognitive functions in patients with Alzheimer's disease. Participants will be randomly assigned to either a dual-task training group or a conventional exercise group. The intervention will last 8 weeks, with three supervised sessions per week. Cognitive performance, mobility, balance, and quality of life will be assessed before and after the intervention.

Detailed description

Alzheimer's disease is a progressive neurodegenerative disorder characterized by impairments in memory, executive function, and daily activities. Conventional exercise programs may improve mobility and physical performance, but their impact on cognition is limited. Dual-task training, which integrates motor and cognitive activities simultaneously, has emerged as a promising strategy to enhance neuroplasticity and functional independence in individuals with cognitive decline. In this study, participants diagnosed with Alzheimer's disease according to standard clinical criteria will be recruited. After baseline assessments, participants will be randomly allocated to one of two groups: Experimental Group (Dual-Task Training): Participants will perform exercises combining cognitive tasks (e.g., arithmetic, memory recall, word association) with simultaneous motor tasks (e.g., walking, balance training, functional mobility exercises). Control Group (Conventional Exercise): Participants will engage in standard physical exercises focusing on strength, flexibility, and balance, without added cognitive tasks. The intervention will span 8 weeks, with three 45-60 minute sessions per week, conducted under supervision by a physiotherapist. Outcome Measures Primary Outcomes: Cognitive performance assessed by the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). Secondary Outcomes: Functional mobility (Timed Up and Go test), balance (Berg Balance Scale), and quality of life (QoL-AD questionnaire). Hypothesis It is hypothesized that dual-task training will lead to greater improvements in cognitive performance and functional independence compared to conventional exercise programs. This study may provide evidence supporting dual-task rehabilitation as a complementary approach in the management of Alzheimer's disease.

Interventions

Type	Name	Description
OTHER	Dual-Task Motor-Cognitive Training	Participants assigned to this group will undergo dual-task motor-cognitive training, which combines physical exercises with simultaneous cognitive tasks. Sessions will last 45-60 minutes, three times per week, for 8 weeks. Exercises will include gait and balance activities performed while engaging in cognitive tasks such as arithmetic, memory recall, or word association.
OTHER	Conventional Exercise Training	Participants in this group will receive a conventional exercise program focusing on strength, flexibility, and balance without a cognitive component. Sessions will last 45-60 minutes, three times per week, for 8 weeks, and will be supervised by a physiotherapist.
