Advances in the application of dual-task training in exercise interventions for older patients with mild cognitive impairment

Early intervention for mild cognitive impairment (MCI) can delay its progression to dementia. Dual-task training focuses on the interaction between cognition and neuromuscular function and has gradually been applied in recent years to interventions targeting cognitive and motor function in older adults with MCI. This article systematically outlines the common types and operational paradigms of dual-task training, explains its mechanisms of action, and, on this basis, focuses on reviewing its intervention effects in older adults with MCI. Dual-task training can serve as an effective nonpharmacological intervention to improve global cognition, executive function, attention, and memory in older adults with MCI, while also enhancing physical functions such as gait speed and balance. Training effects are influenced by factors such as task type and difficulty settings, and individualized programs need to be implemented based on patients' performance in practice. Long-term studies are still needed in the future to verify the long-term stability of intervention effects and promote the development of more standardized intervention protocols.
