What this trial studies

This study follows a cohort of patients diagnosed with early Alzheimer's disease and mild cognitive impairment who are treated with Lecanemab, a drug that targets amyloid-beta aggregation in the brain. The study aims to assess the safety and efficacy of Lecanemab, which has shown promise in previous clinical trials. Participants will undergo evaluations to confirm amyloid pathology and will be monitored for potential adverse effects related to the treatment. The goal is to gather data that could inform future treatment protocols for Alzheimer's disease.

Who should consider this trial

Good fit: Ideal candidates are individuals with early Alzheimer's disease or mild cognitive impairment, confirmed by specific cognitive assessments and amyloid pathology testing.

Not a fit: Patients with significant hemorrhagic conditions, those unable to tolerate MRI scans, or those on anticoagulants may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the effectiveness of Lecanemab in slowing cognitive decline in early Alzheimer's patients.

How similar studies have performed: Previous studies have shown success with Lecanemab in treating Alzheimer's, indicating a promising approach to managing the disease.
