**Study Summary** This study is a pre-screening process to see if individuals might be eligible for future Alzheimer's disease (AD) trials with Roche. Alzheimer's is a brain disease that affects memory and thinking. Before joining a trial, people need to show they have memory concerns, either noticed by themselves or someone else, in the past year. This study helps find out if people are a good fit for other studies. *Participants cannot have difficulties with daily tasks due to memory issues.* They also must not have hearing or vision problems that would stop them from doing memory tests. Glasses and hearing aids are okay. People with other brain conditions causing memory problems, or serious past brain injuries, cannot join. **Key Points:** - The study is a first step (pre-screening) to determine eligibility for future Alzheimer's studies. - Participants should not have other serious medical conditions or brain injuries. - Participation does not involve any treatment, but it helps find suitable candidates for future studies.

Remember, this is just a pre-screening and does not guarantee entry into other trials. It's important to discuss with a healthcare provider before participating.
