This clinical research study is exploring a potential new way to detect and treat individuals in the early stages of Alzheimer's disease or those at risk of developing symptoms. All study-related procedures and tests are provided at no cost. You and your study partner will also be compensated for your time and participation. A study partner is someone who knows you well—such as a spouse, family member, friend, or caregiver—and can help monitor any changes in your memory, mood, or behavior. Your study partner will also consent to participate in the study.
