Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Adequate visual and auditory acuity, in the investigator's judgment, sufficient to perform the neuropsychological testing (eyewear and hearing aids are permitted)
* Evidence of AD pathological process, as confirmed on amyloid PET scan. A CSF tau181/Aβ42 ratio may be used as an alternative option if amyloid PET is not available
* Probable AD dementia or MCI due to AD, also known as an Alzheimer's clinical syndrome clinical Stage 3 or Stage 4
* Screening MMSE score ≥ 22 and CDR-GS of 0.5 or 1.0
* Participant- and/or Informant-reported history of cognitive decline with gradual onset and progression over the last 1 year before screening
* A Repeatable Battery for the Assessment of Neuropsychological Status Delayed Memory Index (RBANS DMI) score of 85 or order
* Availability of a "study partner" as defined by the protocol
Exclusion Criteria
* History or presence of clinically significant cerebrovascular disease
* History of severe, clinically significant (persistent neurologic deficit or structural brain damage) central nervous system (CNS) trauma
* History or presence of clinically significant intracranial mass
* MRI evidence of significant cerebral abnormalities or inability to tolerate MRI procedures or contraindication to MRI
* Any other medical conditions (e.g., cardiovascular, hepatic, renal disease) which are not stable and adequately controlled or which in the opinion of the investigator could affect the participant's safety in the study or interfere with the study assessments
* History of malignancy with the following exceptions: if considered to be cured; malignancies with a negligible risk of metastasis or death
