Introduction: Transcranial direct current stimulation (tDCS) represents a promising approach to neuropsychological rehabilitation, especially among the elderly population. With accelerated global ageing, there is a need to address the challenges related to cognitive decline and memory loss, prevalent conditions that compromise the quality of life of older people. Objective: To analyze the effects of tDCS on cognition and memory in the elderly, consolidating current scientific findings to determine the effectiveness of this technique as a therapeutic intervention. Methods: This is a literature review, using scientific articles from the US National Library of Medicine (PubMed) and Scientific Electronic Library Online (SciELO) databases and Latin American and Caribbean Health Sciences Literature (LILACS). Descriptors from DeCS (Health Sciences Descriptors) were used with the Boolean operator "AND", including the terms "Transcranial Direct Current Stimulation", "Cognition", "Elderly" and "Memory". Free full texts, published in peer-reviewed journals, available in English and Portuguese, and studies published between 2019 and 2024. Results: Initially, 28 articles were found. After applying inclusion and exclusion criteria, 5 articles were selected for the study. The studies showed a positive trend, indicating that tDCS can improve aspects of cognitive function and memory in the elderly. Overall, the results suggest potential benefits. Conclusion: Despite the promising results, caution is needed when interpreting the findings due to the heterogeneity of the studies. However, it seems that tDCS can be a viable tool for cognitive improvement in the elderly.
