| Abstract Background and Aim: Cognitive deficits are a frequent and disabling result of stroke, greatly affecting patients’ quality of life and their ability to recover functionally. Non-invasive brain stimulation (NIBS), which encompasses repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS), has risen as a hopeful treatment for cognitive impairments following a stroke. This systematic review seeks to assess the impact of multi-site NIBS methods on cognitive deficits after a stroke. Methods: A comprehensive search was carried out across various databases, such as Web of Science, PubMed, ScienceDirect, and Scopus, for research published from 2015 to the current date. Inclusion criteria included: (1) studies involving adult stroke patients, (2) interventions utilizing multi-site NIBS methods, and (3) outcomes evaluating cognitive performance. Articles were reviewed and chosen according to PRISMA guidelines, and information on stimulation protocols, targeted brain regions, evaluated cognitive domains, and results was gathered. Results: Numerous studies suggest that multi-site NIBS interventions lead to enhancements in post-stroke cognitive function, especially regarding attention, working memory, and executive functioning. Stimulating specific combinations of brain areas, like the prefrontal and parietal cortices or the cerebellum, seems to boost therapeutic outcomes. Methods that integrate various NIBS techniques, like rTMS and tDCS, demonstrated enhanced and longer-lasting cognitive advantages compared to single-site or single-modality stimulation. Conclusion: Multi-site NIBS seems to be a promising approach for enhancing cognitive deficits post-stroke, particularly when focusing on interlinked cognitive networks. Nonetheless, additional extensive, standardized studies are required to validate the best stimulation parameters and long-term effectiveness. |
