The study is looking at how COVID-19 affects the brain and thinking skills. COVID-19 is caused by a virus called SARS-CoV-2. People who recover from COVID-19 sometimes have ongoing problems like trouble thinking clearly, feeling sad, or anxious. The study uses special tests and scans like **EEG** (checks brain activity) and **MRI** (takes pictures of the brain) to see if there is any brain damage. Blood tests are also used to find signs of brain damage. This will help understand why some people have these problems after COVID-19.

• This study needs in-person visits to the lab in San Francisco.
• You cannot have metal in your body or be uncomfortable in an MRI machine.
• You must be 18-70 years old and had COVID-19 at least 3 months ago.

Joining the study can help scientists learn more about how COVID-19 affects the brain, but some tests might be uncomfortable for those who don't like small spaces or have metal in their body. It's important to consider if you fit the study requirements and whether you're okay with the in-person visits and tests.
