Cocoa Study

Welcome to the Cocoa Flavanols and Memory Study. This study examines the effect of dietary flavanols on brain activity. Flavanols are plant-based nutrients found in cocoa beans, grapes, tea, berries and other fruits and vegetables. In this study, the flavanols come from cocoa and are taken in capsule form every day for a 12-week period.

Study summary:

During an online Consent Appointment, you will read and sign the informed consent form then complete some evaluations to determine initial eligibility.

Before and after the 12 weeks of flavanol intake, you will complete the following:

A series of computer-based and paper/pencil tests to assess memory and attention.
A fasting blood draw.
MRl scans of your brain using a contrast agent called Gadolinium.

Some of these assessments are completed online but some require a visit to the medical center.
