Alzheimer's Disease Begins Years Before Symptoms: Alzheimer's Association Workgroup

Abstract

Background: The major differences between the Alzheimer's Association (AA) and International Working Group (IWG) positions are focused on cognitively unimpaired (CU) individuals with abnormal AD biomarkers. Here we aim to explicate the Alzheimer's Association's (AA) workgroup position on the preclinical stage of Alzheimer's disease (AD).
