What this research studies

You would have brain scans and blood tests before and after anti‑amyloid treatment so researchers can track signs of blood–brain barrier leakiness, tiny tissue changes, and any imaging side effects called ARIA. Imaging will include detailed structural and microstructural MRI measures, and researchers will combine those with clinical information and genetic risk (like APOE4). The team aims to separate harmless fluid or inflammation changes from true nerve‑cell loss that could signal accelerated decline. Results will be used to develop markers that might guide safer, more personalized use of these therapies.

Who could benefit from this research

Good fit: Ideal participants are people with Alzheimer’s disease who are considering or receiving anti‑amyloid immunotherapy, especially those who know their APOE status.

Not a fit: People without Alzheimer’s, those not planning to receive anti‑amyloid treatments, or those unable to travel to the research site are unlikely to benefit directly.

Why it matters

Potential benefit: If successful, this work could help doctors identify people at higher risk for dangerous side effects and tailor anti‑amyloid treatment to reduce harm.

How similar studies have performed: Previous anti‑amyloid trials documented ARIA and an increased risk with APOE4, but using blood‑brain barrier permeability and microstructural MRI as predictive biomarkers is relatively new and not yet proven.
