Cognitive Dysfunction, Memory Disorders
Conditions
Brief summary
The purpose of this study is to test the use of a screening tool to detect changes in the eye that are associated with Alzheimer's disease in adult participants with memory issues. For each participant, the study will last up to one month and requires one visit to the research site.
Interventions
Detailed image of the retina.
Sample will be used to test for a specific form of a protein in the blood to learn more about early detection of Alzheimer's disease.

Eligibility
Inclusion criteria
* Participants who are overtly healthy as determined by medical evaluation, including medical history and physical examination. * Have mild memory complaints or a diagnosis of mild cognitive impairment. * Have undergone genotyping for apolipoprotein E (APOE) and are willing to make results available to the investigator. * Montreal Cognitive Assessment (MoCA) score of greater than or equal to 22 and less than or equal to 28.
Exclusion criteria

Note: mild to moderate cataracts or vision correction with glasses or contact lenses are not
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Percentage of Participants with the Same Results on the Blood Test and Retinal Scan | Day 1 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants who Report High or Moderate Satisfaction with Retinal Scan | Day 1 | Measured by 5-item retinal scan feedback survey. Participants rate their experience with the retinal scan on a 5-item Likert scale that ranges from Strongly Disagree to Strongly Agree. Higher scores are better. |
