This is a prospective, non-interventional study that will enroll participants without dementia who are considered at high, medium, and low risk for developing AD from a community based register (referred to as the CHARIOT registry) in the United Kingdom. Participants will undergo a series of neuropsychological evaluations to characterize the patterns of cognitive change and their inter-relationship in the earliest stages of cognitive impairment. In addition, how such changes relate to the clinical presentation of cognitive impairment of the Alzheimer's type may be evaluated over time. The SubStudy will investigate the longitudinal change of components of the PACC and RBANS in ARAD individuals who have demonstrable amyloid in the brain by either PET or CSF compared with individuals not classified as ARAD. SubStudy participants will be followed every 6 months throughout the SubStudy and will alternate between completing the alternative forms of the PACC and RBANS for a period of up to 4.5 years (54 months). Blood, urine, and saliva samples will be collected from participants during the study for biomarker analyses to assess risk factors for dementia, Alzheimer's disease or confounding factors of dementia risk. Adverse events experienced by the participants during their participation in the study will be monitored.
