This study aims to predict how diseases that cause dementia, like Alzheimer's or Lewy Body Disease, progress over time. Scientists will use tests such as brain imaging (MRI), which takes pictures of the brain, and collect samples of blood and cerebrospinal fluid (the liquid around the brain and spine). They'll also ask questions about how well participants think and behave. The goal is to help doctors diagnose and predict the progression of these diseases better.
- Participants should be between 30-95 years old and have early signs of memory problems or dementia.
- A study partner who knows the participant well is needed for some of the assessments.
- Participants will be checked to ensure they can complete the study tasks.
People who cannot do most of the tests, or whose symptoms are not due to neurodegeneration, will not be able to join. This decision is made by the lead investigator at each site.
