The relationship between recall of recently versus remotely encoded famous faces and amyloidosis in clinically normal older adults.

Abstract

Introduction: Alzheimer's disease (AD) patients exhibit temporally graded memory loss with remote memories remaining more intact than recent memories. It is unclear whether this temporal pattern is observable in clinically normal adults with amyloid pathology (i.e. preclinical AD). Methods: Participants were asked to recall the names of famous figures most prominent recently (famous after 1990) and remotely (famous from 1960-1980) and were provided with a phonemic cue to ensure that memory failure was not purely due to verbal retrieval weaknesses. In addition, participants identified line drawings of objects. Clinically normal older adults (n = 125) were identified as amyloid β positive or n..
