What this trial studies

This observational cohort study aims to estimate the incidence of Alzheimer's disease (AD) among first-degree relatives of AD patients. It employs various methodologies, including neuropsychiatric assessments, MRI, and fluid biomarker analysis, to track cognitive changes over time in individuals at high risk for AD. Additionally, the study investigates environmental and behavioral factors that may influence the incidence of AD. The findings are expected to contribute to the development of prevention and treatment guidelines tailored for the Chinese population.

Who should consider this trial

Good fit: Ideal candidates are first-degree relatives of Alzheimer's patients who are at least 50 years old and have lived in Shanghai for over a year.

Not a fit: Patients with other diseases causing cognitive decline or significant psychological disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved strategies for predicting and preventing Alzheimer's disease in at-risk individuals.

How similar studies have performed: Similar cohort studies have shown promise in understanding Alzheimer's risk factors, but this specific approach focusing on first-degree relatives is relatively novel.
