Commonly Asked Questions

General Questions

What is the APT Webstudy?
The Webstudy monitors volunteers who are 50 and older for changes in their memory through a series of no-cost memory tests. It takes place online, without any in-person visits required. Researchers use the results to monitor volunteers’ memory and, based on possible risk level, invite select volunteers to participate in other Alzheimer’s research studies.
Who is eligible for the APT Webstudy?
Webstudy volunteers must be at least 50 years old, healthy and have access to the internet. People of all races and ethnicities are welcomed and encouraged to participate in the Webstudy in either English or Spanish.
Can a person already diagnosed with Alzheimer’s disease participate in the APT Webstudy?

The Webstudy is not designed for individuals who have already been diagnosed with Alzheimer’s disease dementia or any other form of dementia. Volunteers must be at least 50 years old.

What does participation in the APT Webstudy involve?

First, you complete the registration, consent to participate and then your first round of memory assessments. The two assessments are the Cognitive Function Index (CFI) and the Boston Remote Assessment for Neurocognitive Health (BRANCH), which take about 20 minutes total to complete together. After your first day of BRANCH testing, you will be prompted to return for four consecutive days of additional BRANCH assignments. The daily BRANCH tests take approximately 15 minutes each to complete.

Every three months you will receive an email reminder to take your CFI assessment. Every six months, you will be prompted to take the BRANCH assessment which will be taken once a day for five consecutive days. If researchers notice any changes in your memory and thinking performance over time, you may then be matched with an Alzheimer’s prevention trial, if eligible, but you are under no obligation to join another study.

Can people outside of the United States participate in the APT Webstudy?

The Webstudy is open to all people worldwide. 

How is my personal data protected in the APT Webstudy?
The data privacy of volunteers is of greatest importance, and the Webstudy is required by law to maintain the privacy and security of volunteers’ protected health information. Volunteers may share their memory test information with their doctors by accessing the Summary Report in the participant dashboard.
Who can I contact with questions not answered here?

I don’t want to participate in the APT Webstudy anymore. What should I do?

You can stop participation in the Webstudy at any time by withdrawing your consent. Once you are logged into the Webstudy, follow these steps to remove consent:

  • Select “My Dashboard” from the menu of choices
  • Select “Manage Consent” on the left side of the screen
  • Select “I no longer agree to participate.” If selected, you will no longer receive APT Webstudy emails.

*Note: If you are in the middle of your first visit, you will need to navigate back to the consent section by clicking on the yellow thumbs up at the top of the screen (in the navigation pane) as shown below. Then select “Check to revoke my study consent.” This will immediately revoke your own consent and you will no longer receive emails from the APT Webstudy. 

Assessment Questions

I’m an existing Webstudy participant, where is the Cogstate assessment?
As of December 16, 2024, the Cogstate assessment will no longer be offered through the APT Webstudy for current participants. Instead, we will include a new assessment called the Boston Remote Assessment for Neurocognitive Health (BRANCH), which will be available to you in 2025. We believe that BRANCH will offer a more seamless and accessible experience for participants.
Can I still view my Cogstate scores from previous assessments?
Yes, if you took Cogstate as a past Webstudy participant, your Cogstate results will remain available to view or download through your Summary Report. To find your Summary Report, log into your APT Webstudy account and visit My Dashboard.
Why do I only see the CFI assessment offered to me when I log into my account?
The BRANCH assessment will be introduced to existing APT Webstudy participants in phases in 2025. Once BRANCH is available for you to take, you will be prompted to reconsent to the APT Webstudy and will then be able to complete your BRANCH tests.
What are the Cognitive Function Index (CFI) and Boston Remote Assessment for Neurocognitive Health (BRANCH) tests?
Both assessments are research tools being evaluated for their ability to predict individuals at risk for developing Alzheimer’s in the future. A change in score over time is thought to be most useful in identifying individuals who may be at increased risk for developing Alzheimer’s in the future.
Do I need to use the same type of device for every test assignment?

While it’s important that the same device (i.e. computer, tablet, smartphone) be used each time you retake the assessments, it’s not crucial.  Using the same device does, however, help to ensure that any changes in performance are indicative of genuine change and not simply a result of devices possibly having different processing times.

If I get interrupted, can I restart the CFI and/or BRANCH later?
Unfortunately, if you close the internet browser before you complete your CFI assessment, it will not be saved and you will need to restart from the beginning.

If you are interrupted during your BRANCH assessment, you will be able to continue from where you left off, as long as you haven’t gone too far in the assignment. However, you cannot restart the BRANCH assignment from the beginning on any given testing day.

When will I be able to see my test results? Where will the scores post?
CFI scores should be provided to you as soon as you complete the test every three months. BRANCH results will be posted to your Webstudy account upon completion of your five consecutive testing days, every six months. You will be able to find both your CFI and BRANCH results under My Dashboard once you sign into your account.
What do my CFI and BRANCH results mean?

CFI scores range from 0 to 15. A CFI score of zero is normal and increasing scores over time may indicate a possible decline in subjective cognitive function. A progressively worsening score, a few points increased over each testing session, may reflect worsening function.

BRANCH is composed of three tests focused on learning and memory. A person’s current abilities in these areas of thinking can be characterized by how accurate they are on the tests. Research shows that BRANCH tests are most informative when cognition is measured over several days rather than just one. For this reason we ask that participants take the tests five days in a row rather than just one time. After your fifth consecutive day of BRANCH testing, you will see your results for each completed day of testing portrayed on a graph. An increasing accuracy score day-by-day shows how your memory improves when information is repeated.

**Please note that a single CFI and/or BRANCH score at any given time is not thought to have as much clinical meaning as a change in score over time.  As you progress in the APT Webstudy, we will be able to monitor changes which we believe will be useful in predicting individuals at increased risk for developing Alzheimer’s disease. A change in score over time is thought to have a predictive value that would be confirmed by in-clinic evaluation. Of course, should you have concerns about your memory, you should consult with your personal physician.**

Can I retake my assessments if I don’t feel I did well on them?
The goal of the APT Webstudy is to monitor a person’s memory and thinking performance overtime. While we can’t delete any of your tests, one bad score will not completely skew your overall status that we see. We will be looking at all of your scores over time, so we will notice if one doesn’t seem right especially if it was your first time taking the assessments.
I received an email letting me know that it’s time to take the CFI and/or BRANCH again. Where do I go to do this?

Log in to your APT Webstudy account. Navigate to My Memory from the menu of options you should see.

If it’s time to take your next set of CFI and/or BRANCH assessments, they will be “unlocked” and you should be able to click on the blue “Take CFI Assessment” or “Take BRANCH Assessment” button(s).  If it is not quite time yet, you should see the date of the next availability to retake.
