We aimed to characterize the nature and magnitude of cognitive decline in a group of adults
with amnestic mild cognitive impairment (aMCI) with high and low levels of amyloid-(A) in …

Background: It has been proposed that only mild cognitive impairment (MCI) with high Aβ
amyloid is indicative of incipient Alzheimer's disease (AD), yet MCI with low Aβ amyloid may …

High amyloid has been associated with substantial episodic memory decline over 18 and 36
months in healthy older adults and individuals with mild cognitive impairment. However, the …

We aimed to characterize the nature and magnitude of cognitive decline in a group of
healthy older adults with high and low levels of amyloid-(A) and who were APOE 4 carriers …

Background: The detection of early Alzheimer's disease (AD) can rely on subjective and
informant reports of cognitive impairment. However, relationships between subjective …

Patients with amnestic mild cognitive impairment (aMCI) are considered to have a high risk
for Alzheimer dementia (AD). Even high positive predictive values, however, cannot be …

Introduction Patients with amnestic mild cognitive impairment (aMCI) are heterogeneous as
regard to their amyloid status. The present study aimed at highlighting the …

Background: To date evidence of the relationship between cognition and Aβ amyloid during
the early stages of Alzheimer's Disease (AD) has been inconsistent. This study aimed to …

Background Mild cognitive impairment (MCI) is a heterogeneous syndrome resulting from
Alzheimer's disease (AD) as well as to non-AD and non-neurodegenerative conditions. A …
