This review article was conducted to investigate the association between dark chocolate consumption and the risk of Alzheimer’s disease (AD). AD is a progressive neurological disorder characterized by a gradual decline in memory and social functioning.
This narrative review study was conducted to search for scientific papers in English from 2000 to 2026 published in the Scopus and PubMed databases. Keywords included dark chocolate, cocoa, oxidative stress, Alzheimer’s and cognitive function.
Regular consumption of flavonoid-rich dark chocolate has been linked to significant improvements in cognitive functions, including memory and concentration. Studies reported better maintenance of cognitive function and favorable neuropsychological test results among people who consume dark chocolate.
Evidence from human studies suggests that regular consumption of flavonoid-rich dark chocolate may support cognitive function and reduce oxidative stress and inflammation in AD. Furthermore, well-designed clinical trials are needed to confirm causality, clarify the effective dose and determine long-term effects.
