What is the purpose of the Digital phase of the ADNI4 Study?

To study changes in memory and thinking, we ask participants to answer questions about themselves over time. We also use memory tests to learn what problems people may be having with thinking and remembering. The tests for the Digital phase of the ADNI4 study are done online. We ask all of those in the study to come back to the website every 6 months to answer questions and do a memory test so that we can see any changes. Some people in the study will be asked to do other kinds of tests, such as give a blood sample. All the information that people in ADNI4 offer adds to our knowledge. Your participation moves us forward in our study of aging, memory changes, and Alzheimer’s disease.
