Longitudinal Changes in P3 Event‐related Potential among Older Adults with Preclinical Alzheimer’s Disease: A 1‐year Follow‐Up

The third positive peak of the event‐related potential (ERP P3) is understood to reflect neural resource utilization during working memory. We previously showed lower P3 ERP amplitude of the task effect in older adults with preclinical Alzheimer’s disease (AD). The aim of this study was to compare changes from baseline to 1‐year follow‐up in P3 ERP between older adults with and without preclinical AD.
