Does resveratrol improve cognition in humans? A scientometric study to an in‐depth review

AIM: In order to understand the different processes and mechanisms of cognitive function and resveratrol (RES) as an active participant in pathophysiological events that affect cognitive function. METHODS: First, the Web of Science (core collection) was selected as the data source. To ensure the comprehensiveness and accuracy of the search data, the index was selected as “SCI‐EXPANDED”, and the search formula was TS = resveratrol AND TS = (“cognitive” OR “memory” OR “cognition” OR “mood”). Next, details of authors, keywords, journals, countries, institutions, references, and more were analyzed by CiteSpace and VOSviewer software. Finally, we explored the mechanism by which RES could improve cognitive impairment, that involves healthy young adults, healthy elderly, post‐menopausal women, and diseases involving Alzheimer's disease (AD), diabetes‐related cognitive impairment, mental illness, post‐stroke cognitive impairment, and neonatal hypoxic–ischemic injury. RESULTS: 287 valid papers were obtained. The scientometric results demonstrated 287 papers used in this study came from 1601 authors from 443 organizations in 38 countries, published in 169 journals, and cited 13,680 literatures from 2431 journals. Depression, AD, cerebral ischemia, diabetic cognitive impairment, and cognitive function in the elderly are all keywords of the co‐occurrence network. CONCLUSION: This study supports the hypothesis that chronic RES intake may positively affect brain function. But it has become challenging to determine the optimal dose, time and duration of RES and improve the bioavailability of RES, which many researchers need to overcome.
