Vitamin C levels in blood plasma linked with brain connectivity and volume in older adults

AI Summary

A study involving 2,044 older Japanese adults found a correlation between lower vitamin C levels in blood plasma and reduced brain gray matter volume and connectivity in the default mode network. This research highlights the potential importance of vitamin C for brain health in aging populations.

A study of 2,044 older Japanese adults found that those with lower vitamin C levels in their blood plasma tended to have a lower volume of gray matter in their brains, as well as lower connectivity among a collection of brain regions known as the default mode network. Haruka Nagaya of Hirosaki University, Japan, and colleagues present these findings in PLOS One.
