What this trial studies

This observational study aims to evaluate the effectiveness of specific blood biomarkers in identifying Alzheimer's disease and related cognitive impairments. It focuses on biomarkers such as Aβ40, Aβ42, P-Tau181, P-Tau217, GFAP, and NfL in various patient groups, including those diagnosed with Alzheimer's, those with mild cognitive impairment, and cognitively normal individuals. The study seeks to establish a reliable model for early detection of Alzheimer's disease through blood testing.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 50 and older who have Alzheimer's disease, mild cognitive impairment, or are cognitively normal.

Not a fit: Patients with other disorders causing cognitive impairment or those unable to cooperate with cognitive assessments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to earlier and more accurate screening for Alzheimer's disease, allowing for timely interventions.

How similar studies have performed: Other studies have shown promise in using blood biomarkers for Alzheimer's screening, indicating potential success for this approach.
