New drugs for Alzheimer's disease, lecanemab and donanemab, can slow decline in early symptomatic disease by 20–40%. Both work by clearing amyloid, the sticky protein that builds up in the brains of people with the disease.

What they work on

  1. Identify clinical, genetic and proteomic predictors of ARIA risk in patients receiving amyloid-targeted treatments, using the DIAN-TU trial cohort and the real-world Memory Diagnostic Clinic cohort.
  2. Develop and validate blood-based biomarkers that detect the onset and resolution of ARIA, to reduce reliance on intensive MRI monitoring.
  3. Evaluate the clinical and cognitive consequences of ARIA-E (brain swelling) after anti-amyloid therapy, comparing autosomal dominant and sporadic Alzheimer's disease.

More about the research

However, they can cause amyloid-related imaging abnormalities (ARIA), side effects such as brain swelling or small bleeds seen on brain scans. Patients therefore need frequent MRI scans, which limits who can safely receive these drugs. Little is known about what causes ARIA or how to predict it.

Why it matters

Patients with early Alzheimer's disease could gain safer and more accessible access to lecanemab and donanemab if blood tests and risk profiles can predict and monitor ARIA. Such tools could reduce the need for repeated MRI scans and help doctors choose which patients are good candidates for treatment, making care more personalized.
