How should we select participants to test with the T-cog?
Each Center may determine which participants to test based on local considerations. Centers that participate in the inter-ADRC validation study will receive a plan for randomizing participants, who will receive both in-person and T-cog visits.
How can we distinguish distractions from interruptions?
It can be difficult to determine this remotely. Occasionally someone at the participant’s home interrupts (you may hear them speaking in the background, for instance). When permitted by the Neuropsychologic Battery Instructions, we suggest repeating. However, it is also important to ask participants before starting if they are alone in a quiet spot where they will not be disturbed.
Is there a separate battery for controls? Currently there is no separate battery for controls. With additional experience, this may change, e.g., for participants with AD, we may recommend administering only the core battery.
