  1. Baseline Amyloid PET Centiloid Score and Risk of Amyloid-Related Imaging Abnormalities in Patients Treated With Lecanemab

    ✓ Peer-reviewed alzhub usefulness score 50 out of 100. AJNR. American journal of neuroradiology 2026-08-13 Treatments

    Baseline global Centiloid was not independently associated with ARIA in patients treated with lecanemab.

  2. Demographic and Clinical Characteristics of Patients Treated With Lecanemab Stratified by Amyloid-Related Imaging Abnormality Status

    ✓ Peer-reviewed alzhub usefulness score 66 out of 100. Cureus 2026-08-13 Treatments

    In this real-world cohort of patients treated with lecanemab, ARIAs occurred in nearly one-third of patients.

  3. Reduced diffusion associated with amyloid-related imaging abnormalities in three patients treated with donanemab

    ✓ Peer-reviewed alzhub usefulness score 48 out of 100. Neurocase 2026-07-02 Treatments

    Amyloid-related imaging abnormalities (ARIA) with edema (ARIA-E) and with hemorrhage (ARIA-H) are common adverse effects of amyloid-targeting therapies (ATT), characterized on MRI by T2/fluid-attenuated inversion recovery (FLAIR) hyperintensities and susceptibility-sensitive hypointensities, respectively.

  4. Multiple ischemic strokes in a patient treated with Lecanemab: a case report

    ✓ Peer-reviewed alzhub usefulness score 47 out of 100. Neurocase 2025-10-16 Treatments

    Amyloid-lowering therapy via administration of monoclonal antibodies against amyloid beta has been previously associated with the formation of cerebral edema and/or microhemorrhage.

  5. MRI protocols and sequences for amyloid-related imaging abnormalities monitoring in Alzheimer's disease patients treated with monoclonal antibodies

    ✓ Peer-reviewed alzhub usefulness score 41 out of 100. Current opinion in neurology 2025-06-04 Treatments

    This review provides an updated overview of amyloid-related imaging abnormalities (ARIA) associated with antiamyloid monoclonal antibodies (mAbs) in Alzheimer's disease (AD).
