Each article identified: year of publication, language of publication, country of publication, name of the journal and subject of the study. The guidelines established by PRISMA were used. Fifty-one scientific publications were included, analyzed in 34 journals. China leads with 14 studies (27.5%), followed by the United States with 5 articles (9.8%). Korea and Singapore are in third place with 4 studies each (7.8%), followed by Japan with 3 studies (5.9%). Regarding the language of publication, 96.1% (n=49) were published in English. Only 3.9% (n=2) were published in Spanish. The journal with the highest frequency of publications was Nutrients, with 6 articles published, representing 11.8% of the total and standing out as a leader in this field. It was followed by BMC Geriatrics with 3 published articles, representing 5.9% of the total. There was a notable increase in research on interventions for cognitive impairment in OAs, mainly concentrated in the years 2020 and 2023. China leads the production of studies followed by the United States, Korea and Singapore. The most studied intervention programs include exercise and sport, followed by nutrition and computerized training. The journal “Nutrients” stands out with the highest number of articles, followed by “BMC Geriatrics”.
