Inclusion criteria

* Ability and willingness to participate in an interventional clinical study, including meeting key eligibility criteria of linked interventional Roche AD studies (e.g., specific age ranges) * Ability and willingness to receive information about potential eligibility in an associated interventional Roche AD study

Exclusion criteria

* Dependency in basic activities of daily living (bADLs) due to cognitive impairment * Visual or auditory impairment that would prevent them from performing the cognitive assessments (eyeglasses and hearing aids are permitted) * Any self-reported evidence or known diagnosis of a neurological or neurodegenerative condition that may lead to cognitive impairment other than AD * History of severe, clinically significant central nervous system trauma * Any serious medical condition that precludes a participant's safe participation and completion of a clinical study * For participants with a clinical diagnosis of MCI or mild AD: Previous AD diagnosis based on biomarker confirmation with an approved or validated rule in method (e.g., amyloid PET or cerebrospinal fluid, blood biomarker) is exclusionary
