FAQ: General Questions

What will the study achieve?

CAN-PROTECT will provide valuable information about how the brain ages by assessing relationships between health, wellness, stress, exercise, diet, exercise, behaviour, and other factors with measures of memory and thinking. In addition to enrolling individuals 18 years of age and older, CAN-PROTECT will also enrol participants who care for persons with cognitive disorders like Alzheimer’s disease and related dementias. The study will assess dementia-specific issues in caregivers, both informal (e.g., family members, friends) and formal (e.g., personal care aids, nurses, recreation therapists, social workers, physicians, etc.). CAN-PROTECT will help develop better approaches to prevent and treat dementia in the future and also inform development of resources and supports for dementia caregivers.

How long will the study last?

Participants will be invited to complete a series of assessments online which will be repeated annually. Currently the study runs for two years, but we anticipate extending this substantially in those who are interested.

Can I opt out of the study?

Yes, once registered you can opt out of the study at any time by selecting the Withdraw from Study option from the Manage Account section of your dashboard. You will be able to choose whether your personal data that identifies you is deleted permanently. If you permanently delete your data and wish to continue the study after opting out, you will need to re-register and re-enter any data previously submitted.

My question isn't included here - who else can I ask?

FAQ: Completing your assessments

I'm going away and can't complete an assessment before the due date

If you cannot complete your assessments by their due date, we will record a missing data point for the current round of assessments and the assessment will become available in the next round of assessments if it is a recurring assessment. The assessments become available when you begin the cognitive tests each year so if you are going to be away, you can wait until you return to begin.

What happens if I miss the due date for an assessment?

You have two months to begin your cognitive tests but after you begin them, you must complete them within one week. If the cognitive tests expire without any of the three sessions completed, you will not be able to do any other questionnaires. After you complete the first cognitive test session, the questionnaires become available and must be completed within 6 months. If your assessments expire, you will not be able to complete them until the following year.

What happens if I'm unable to repeat an assessment when requested?

We would prefer you to complete all repetitions within the available time window as this will give us more accurate data, but don't worry if you can't, any data you have submitted is still very valuable to us.

I didn't finish an assessment and now it won't let me restart

Some assessments don't allow you to restart if already started or the time window for completing has expired. If you don't think your time window has expired, please try again leaving at least 24 hours before retrying. If you cannot restart the assessment any data already provided will have been saved and will still be useful.

Can I retake an assessment?

Once an assessment has been submitted it cannot be retaken. Please review your answers carefully before submitting. You will be able to do the cognitive assessments three times so you can try again 12 hours after your first and second attempt.

FAQ: Playing brain training games

FAQ: Study Partners

What is a study partner?

A study partner is someone who can complete some simple assessments about you, for example how well you perform various tasks now compared to several years ago. You must have known the study partner well for at least five years, for example a friend or family member, and they must be age 18 or over.

You will be asked to provide the name and email address of a person who can act as your study partner during registration or you can add these details later. We will invite them to confirm they are willing to act as your study partner and if so, they will register for their own study account. A study partner will not be able to view or access any other information you provide as part of the study nor will you be able to view or access any information provided by the study partner.

Please note that a study partner may already be a participant in the study or can choose to become a participant if they meet the qualifying criteria.

Nominating a study partner is a mandatory part of the study; you won’t be able to participate without one.

Can I change or remove my study partner?
