Computerized Tests of Cognitive Decline in Presymptomatic Alzheimer's Disease
This trial is testing a new set of computerized cognitive assessments called the California Cognitive Assessment Battery. Researchers want to establish normal performance benchmarks across different ages, so the tests can eventually flag early signs of cognitive decline. It is not a drug trial — it is a diagnostic study, meaning it is testing a measuring tool, not a treatment. There is no experimental intervention here beyond taking the tests themselves.
