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.\n\nIn 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:\n\nExperimental 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).\n\nControl Group (Conventional Exercise): Participants will engage in standard physical exercises focusing on strength, flexibility, and balance, without added cognitive tasks.\n\nThe intervention will span 8 weeks, with three 45-60 minute sessions per week, conducted under supervision by a physiotherapist.\n\nOutcome Measures\n\nPrimary Outcomes: Cognitive performance assessed by the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA).\n\nSecondary Outcomes: Functional mobility (Timed Up and Go test), balance (Berg Balance Scale), and quality of life (QoL-AD questionnaire).\n\nHypothesis\n\nIt 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.",[74,80],{"label":75,"type":76,"description":77,"interventionNames":78},"Dual-task motor-cognitive training","EXPERIMENTAL","Participants assigned to this group will undergo dual-task motor-cognitive training, which combines physical exercises with simultaneous cognitive tasks.
