Persistent neuropathological effects 14 years following amyloid-β immunization in Alzheimer’s disease

We performed a 15-year post-mortem neuropathological follow-up of patients in the first trial of amyloid-β immunotherapy for Alzheimer’s disease. Twenty-two participants of a clinical trial of active amyloid-β42 immunization (AN1792, Elan Pharmaceuticals) or placebo were studied.
