Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Blueberries are rich in flavonoids that possess antioxidant and anti-inflammatory properties, which in rodent models are neuro-protective. The risk of developing dementia is reduced in people habitually consuming high flavonoid intakes, but data from human intervention studies is sparse. We therefore investigated whether 12 weeks of blueberry concentrate supplementation improved cognitive function in healthy elderly via increased brain activation and perfusion.
