Objective: To examine the effects of dual-task cognitive training combined with transcranial direct current stimulation (tDCS) on cognitive and daily functioning in older adults. Methods: Ten older adults participated in an eight-session dual-task cognitive training program combined with tDCS. Pre- and post-intervention assessments measured cognitive function, activities of daily living, attention, and brain activity using validated tools. Results: Post-intervention analyses showed significant improvements in cognitive function (measured by the Comprehensive Item Selection Test and the Korean version of the Montreal Cognitive Assessment), instrumental activities of daily living (measured by the Korean version of the Instrumental Activities of Daily Living scale), and reduced cognitive decline (measured by the Global Deterioration Scale) (all p < .05). No significant changes were observed in attentional control (measured by the Attentional Control Questionnaire) or in the accuracy and reaction times on the N-back and Stroop tasks. Conclusion: Combined dual-task cognitive training and tDCS may improve cognitive function and activities of daily living in older adults. Further research is warranted to validate and optimize this intervention.
