There are several steps that take place during this research study. Our research assistants work to ensure that participants are informed and engaged every step of the way. Take a look at our F.A.Q. below for answers to our most frequently asked questions.



I am currently being treated for attention and memory problems – would I be able to participate in the study?

We are looking for healthy volunteers aged between 50-69. You will need to undergo a phone screen to see if you are eligible to participate in the study. 

Do I have to undergo the MRI testing?

The MRI testing is not optional. Subjects who have any MRI or related contraindications to the MRI testing contrast agent, gadolinium, will not be considered eligible. 

Will I receive the results of the study?

Because we are still actively recruiting for our study, we won’t be able to provide you the results of the study at this time. However, we can provide you and your physician with the results of your MRI scans. 

Do you pay for transportation during the study?

No, you will not receive a travel reimbursement.

What are dietary cocoa flavanols? 

Flavanoids belong to a group of natural substances with phenolic structures built around a cone flavone structure and are found in plants such as cocoa and food products such as wine [1]. Flavanoids can be divided on the basis of their structure into flavones, flavanols and anthocyanins. The mechanisms by which flavonoids are suspected to yield their healthy effects include, anti-oxidant, anti-inflammatory, anti-adhesive, anti-thrombotic, vasodilatory and anti-tumor effects [2]. 

Flavanols are the main type of flavonoids found in cacao beans. Cacao beans, from which chocolate is made, come from the fruit of the tree, Theobroma cacao, which grows mainly in subtropical climates.
