Abstract
Introduction: The main objective of this review is to present a new approach to the memory deficit in Alzheimer’s disease. Recent memory models suggest that information is recovered either on the basis of recollection or on the basis on familiarity. Recollection, unlike familiarity, requires the retrieval of contextual details related to the encoded information.
State of the art: This review suggests that recollection is particularly affected in Alzheimer’s disease. In contrast, familiarity seems to be relatively preserved. A related deficit in metamemory is observed when recollection is required; a decrease in recollection in Alzheimer’s disease could explain the pattern of metamemory problems. The deficit in recollection could be explained by a disconnection between medial temporal areas and frontal areas.
Perspectives: This novel approach to memory gives research perspectives concerning both early diagnosis and rehabilitation strategies of Alzheimer disease.
Conclusion: This overview showed deficits in conscious memory processes conceived of as recollection. These novel insights should provide new explanations for the deficits observed in Alzheimer’s disease, particularly metamemory.
