The Behavioral Neurology program is conducting an NIH-funded study to try to understand and clarify why some individuals develop Alzheimer’s disease at a young age. By understanding the reasons for early-onset Alzheimer’s disease, the investigators hope to shed light on what happens in Alzheimer’s disease at all ages. Participants will undergo neurological tasks, neuropsychological assessments, and a special MRI of structural and functional brain networks. The study is approximately 1 year long, with 3 visits within the first month and 2 visits at the 1-year follow up. Study participation is open to all patients with Alzheimer’s disease, but especially those diagnosed with early-onset Alzheimer’s disease (diagnosed before age 65).
