The gut microbiota associated with pineal gland calcification.

This article investigates the association between the degree of pineal gland calcification (DOC) and gut microbiota composition in older Japanese adults. The study analyzed 178 individuals aged 65 and older using head computed tomography to assess DOC and 16S rRNA sequencing of stool samples to characterize gut microbiota. Results showed that butyrate-producing bacteria, including Faecalibacterium, Coprococcus, and Roseburia, were significantly more abundant in participants with low DOC scores, while other genera were more prevalent in those with high DOC scores. These findings suggest a potential link between reduced butyrate-producing gut bacteria and increased pineal gland calcification, which may have implications for cognitive impairment and age-related brain conditions.
