A Study of Retinal Imaging to Detect Abnormal Protein Deposits Associated With Alzheimer's Disease
This study tests whether a retinal scan, paired with a blood test, can pick up eye changes linked to Alzheimer's-related protein buildup in adults with mild memory complaints or mild cognitive impairment. It involves one visit and no drug. The phase is unspecified, so this is an early look at a screening tool, not a proven test.
You may qualify if
- 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.
You're excluded if
- Have any medical condition that, in the opinion of the investigator, would be a contraindication to participation in the study.
- Have an existing diagnosis of AD or other dementia.
- Have contradictions to or an allergy to the ophthalmic dilating agents.
- Have known diagnosis of severe glaucoma or severe cataracts; have a significant refractive error (more than 12 diopters [D] of spherical equivalent refraction); or have any ocular media opacity that prevents imaging of the retina (that is, severe cataract). Note: mild to moderate cataracts or vision correction with glasses or contact lenses are not exclusion criteria.
- Current or previous treatment with anti-amyloid medications.
- Are currently enrolled in any other clinical study involving an investigational product or any other type of medical research judged not to be scientifically or medically compatible with this study.
