SCD
As individuals age, cognitive complaints become increasingly common and are often a reflection of the normal aging process. For a smaller subset of individuals, however, cognitive concerns may represent early changes due to Alzheimer’s disease. This study aims to investigate the pattern of cognitive concerns overtime that may help to predict risk of Alzheimer’s disease. Individuals will be followed for 3 years with cognitive testing, questionnaires about cognitive functioning and mood, and brain imaging to answer these questions.
