Everyday Memory Failures in Older Adults with Amnestic Mild Cognitive Impairment

Prospective memory in amnestic mild cognitive impairment.

Individuals with amnestic mild cognitive impairment (aMCI) often complain of difficulty remembering to carry out intended actions, consistent with findings of impaired prospective memory (PM) in this population. In this study, individuals with aMCI (N = 27) performed worse than healthy controls (N = 27) on the Memory for Intentions Screening Test (Raskin, 2004), including on time- and event-bas...

Alterations in working memory networks in amnestic mild cognitive impairment.

Patients with amnestic mild cognitive impairment (aMCI) show preserved or mildly impaired working memory, despite their deficits in episodic memory. We aimed to identify performance and/or neural differences between aMCI patients and matched controls on a standard working memory fMRI task. Neuropsychological assessment demonstrated aMCI impairments in verbal and visual episodic long-term memory...

iii RECOGNITION MEMORY IN AMNESTIC MILD COGNITIVE IMPAIRMENT

Event-based prospective memory failure in amnestic mild cognitive impairment.

Prospective memory (PM) deficits have recently been documented in individuals with amnestic mild cognitive impairment (aMCI). In this paper, we investigated whether these deficits are due to the failure of retrospective memory processes. We also examined the role played by attentional/executive processes in PM functioning. We enrolled 24 individuals with aMCI and 24 healthy controls (NCs). In t...

Semantic memory activation in amnestic mild cognitive impairment.

Cognitively intact older individuals at risk for developing Alzheimer's disease frequently show increased functional magnetic resonance imaging (fMRI) brain activation presumably associated with compensatory recruitment, whereas mild cognitive impairment (MCI) patients tend not to show increased activation presumably due to reduced neural reserve. Previous studies, however, have typically used ...
