Information for Participants

What will happen if I join the RECALL study?

If you are interested in the study, please submit an expression of interest here. 

You will be contacted by a member of the study team with further information about the study and some further surveys for you to fill out.

Initial screening

You'll get a message from the study team with more details, a consent form to complete and some surveys to fill in. They'll ask about your health and medications through online questions. This is to make sure it's safe for you to join and that you meet the requirements. You'll also do a short cognitive test on the computer lasting around 15-20 minutes. This will tell us more about your current memory and thinking skills.

Study Begins

If you are eligible for the study, we will send medication to the address you have provided along with a blood pressure monitor and an order for 2 blood tests. You will be asked to take your medication once a day for 60 days. If you receive a blood pressure monitor, you will be asked to record your blood pressure at various points. Instructions on how to set up your monitor will be sent to you and found on our FAQs page.

Mid-Study Assessment

Participants will be asked to complete an online survey at week 4 of the study and record their blood pressure again.

End of Study

Once the 60-day study period is over, you will be asked to:

  • Measure your blood pressure.
  • Get a blood test.
  • Take one final survey.
  • Complete the cognitive testing.

Who Can Participate?

  • Participants must be 70 years or older
  • Access to an email address, internet, and a device (laptop, computer, tablet, or smartphone) is required for online testing
  • Participants need to share their GP’s information and designate a ‘study buddy’ (partner, relative, child, sibling, or friend) for contact if needed


Key Study Details

  • The study involves taking a low-dose blood pressure lowering pill for 60 days, which will be posted to you. 

  • Participation also involves taking an online cognitive test via an online testing service called Creyos and completing short health and quality of life questionnaires periodically over an 8-week period. You do this in the convenience of your own home. 

  • All participants will be asked to have a blood test at the participant’s local Douglas Hanly Moir pathology centre at the beginning and end of the study. A blood test request form will be posted to you and there is no cost for the test. 

Why Participate?

  • You will be helping us to learn more about preventing Dementia and Mild Cognitive Impairment and your contribution will provide valuable information to benefit others in the future. 

  • You may receive a blood pressure monitor, and you might get better blood pressure readings. 

  • You will be provided all of the study tests and medication free of charge.
