  1. Amyloid Positron Emission Tomography Imaging at the Onset of Amyloid-Related Abnormalities With Edema in an Alzheimer's Disease Patient

    ✓ Peer-reviewed alzhub usefulness score 50 out of 100. Cureus 2025-12-28 Treatments

    Amyloid-related imaging abnormalities with edema (ARIA-E) are known adverse events of anti-amyloid monoclonal antibody therapy for Alzheimer's disease (AD), but to our knowledge, amyloid positron emission tomography (PET) captured exactly at the moment of ARIA-E onset has not previously been reported.

  2. Fatal Iatrogenic Cerebral Amyloid-Related Encephalitis in a patient treated with lecanemab for Alzheimer’s disease: neuroimaging and neuropathology

    ⚠ Preprint — not yet peer-reviewed alzhub usefulness score 16 out of 100. Research Square 2023-05-10 Treatments

    Magnetic resonance imaging revealed multifocal cerebral edema and an increased burden of cerebral microhemorrhages compared to pre-trial imaging, consistent with Amyloid Related Imaging Abnormality (ARIA).

  3. Fatal Iatrogenic Cerebral Amyloid-Related Encephalitis in a patient treated with lecanemab for Alzheimer’s disease: neuroimaging and neuropathology

    ⚠ Preprint — not yet peer-reviewed alzhub usefulness score 16 out of 100. medRxiv 2023-04-29 Treatments

    We report the case of an elderly woman in good general health aside from early-stage Alzheimer’s disease who was enrolled in a randomized controlled trial of the novel therapeutic monoclonal antibody lecanemab where she was treated with the placebo, and subsequently in the open label extension study where she received lecanemab infusions every two weeks.
