Using eye imaging and blood tests to detect Alzheimer's early

Multimodal Ophthalmic Imaging and Plasma Biomarkers for the Early Detection of Alzheimer's Disease

Peking University First Hospital · NCT06924359

This study is testing if eye scans and blood tests can help find signs of Alzheimer's disease earlier in people aged 50 and older, whether they have the disease or not.

What this trial studies

This observational study focuses on identifying specific plasma biomarkers and ocular indicators that can aid in the early detection of Alzheimer's disease. Participants aged 50 and older, including those diagnosed with Alzheimer's, mild cognitive decline, subjective cognitive decline, or who are cognitively normal, will undergo multimodal ophthalmic imaging and blood sampling. The study aims to establish a correlation between ocular changes and plasma biomarkers associated with Alzheimer's, potentially leading to earlier diagnosis and intervention.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 50 and older, with a diagnosis of Alzheimer's disease, mild cognitive decline, subjective cognitive decline, or those who are cognitively normal.

Not a fit: Patients with other neurological disorders or systemic diseases that may cause cognitive impairment are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this study could enable earlier detection of Alzheimer's disease, allowing for timely interventions that may slow disease progression.

How similar studies have performed: While the approach of using multimodal imaging and plasma biomarkers is promising, it is still relatively novel and has not been extensively tested in previous studies.
