Overview
Brief Summary
Bio-Hermes-002 is a 120-day cross-sectional study that will result in a blood, CSF, retinal, digital, MRI, and PET brain imaging biomarker database that can be used to determine the primary objective. Digital biomarkers and blood-based biomarkers will be tested to determine whether a meaningful relationship exists between biomarkers alone or in combination with tau or amyloid brain pathology identified through PET images.

Inclusion Criteria
- •Pre-screening Inclusion Criteria
- •Participants must meet ALL of the following criteria to progress to Visit 1 (Screening):
- •Participant is between 60 to 90 years of age (inclusive) at the time of consent; and
- •Participant has a study partner who has sufficient and frequent contact with the participant (defined as at least 8 hours of contact a week) and is able to provide accurate information regarding the participant's cognitive and functional abilities.
- •Core Study Inclusion Criteria
- •Participants must meet ALL of the following criteria, in addition to the Pre-screening Inclusion Criteria, for entry into the study:
- •Participants must provide written consent in the IRB-approved or Ethics Committee (EC) approved informed consent form or have a legally authorized representative (LAR) provide written consent on the participant's behalf in accordance with local and national guidance and regulation;
- •Participants must be willing to undergo an MRI brain scan within 90 days and an amyloid and tau PET scan within 120 days of signing informed consent;
- •Participants must be willing to comply with all study procedures as outlined in the informed consent, including blood sampling, genetic testing, and storage of biospecimens for future research;
- •Fluency in the language of the tests used at the study site;
Exclusion Criteria
- •Pre-screening Exclusion Criteria
- •Participants who meet ANY of the following criteria will not be eligible to progress to Visit 1 (Screening):
- •Participant is unable to undergo amyloid and tau PET scans due to self-reported pregnancy, sensitivity to ligands being used, poor venous access, contraindication to PET, or planned or recent exposure to ionizing radiation that in combination with the planned administration of amyloid radioligand would result in a cumulative exposure that exceeds recommended local guidelines;
- •Participants who have reported or have a known negative amyloid PET scan in the past 6 months;
- •Participants with any known contraindication to brain MRI scan;
- •Participants with history of stroke or seizures within 1 year of the Pre-Screening Visit;
- •Participants with history of cancer within the past 5 years with the exception of non-melanoma skin cancer or prostate cancer in situ;
- •Participants with known or suspected alcohol or drug abuse or dependence within 1 year of the Pre- Screening Visit;
- •Participants who report any current unstable psychiatric symptoms that could interfere with study procedures or impact study data (e.g., uncontrolled depression);
- •Participants who have received any potential disease modifying AD treatment within 6 months prior to the Pre-screening Visit; and

Outcomes
Primary Outcomes
Biomarkers and PET
Time Frame: Through study completion, an average of 3 years
Measure blood biomarkers (Aβ 42/40, p-tau 181, p-tau 217, p-tau 231, total tau, and NFL) to see if it will predict the extent of tau and amyloid brain pathology as measured by PET brain imaging in participants shown to be cognitively normal (CN), have mild cognitive impairment (MCI), or have mild-to-moderate AD dementia.
Secondary Outcomes
