Elevated hippocampal activation is observed in conditions that confer risk for Alzheimer’s disease, including amnestic mild cognitive impairment (aMCI). Studies in relevant animal models have indicated that overactivity in selective hippocampal circuits contributes to cognitive impairment. Here, we tested the effect of reducing hippocampal activation in aMCI. Under placebo treatment, hippocampal activation in the dentate […]

The aim of our study was to verify reported visual dysfunctions of patients with Alzheimer disease with the use of several variants of VEPs and visual ERPs and to learn whether these methods can be useful in diagnostics of AD. We tested 15 patients (6 women and 9 men, aged from 58 to 87) with […]

Objective: We conducted a combined observational cohort and case-control study in patients with Alzheimer disease (AD) to assess the effects of acetylcholinesterase inhibitor (ChEI) treatment on cognitive functions important for driving.; Methods: Performance of 24 outpatients with newly diagnosed (untreated) early-stage AD was compared before beginning ChEI (pre-ChEI) and after 3 months of therapy (post-ChEI) […]
Evaluations of dementia by EEG frequency analysis and psychological examination
In order to evaluate the stage of dementia, we focused attention on EEG rhythms and Hasegawa-dementia-rating scale (HDS-R). Frontal EEGs were recorded from dementia patients and normal controls during music and photo-image stimulations, and frequency analysis was performed. In the controls, profiles of rhythm pattern during music stimulation seemed to be markedly different from those […]
Cognitive rehabilitation changes memory-related brain activity in people with Alzheimer disease

Yuen, K. S. L.,
Woods, R. T.,
Evans, S. J.,
Parkinson, C. H.,
Rugg, M. D.,
Linden, D. E. J.
Background: People with Alzheimer disease (AD) are capable of new learning when cognitive support is provided, suggesting that there is plasticity even in a degenerating brain. However, it is unclear how a cognition-focused intervention operates on a neural level.; Objective: The present study examined the effects of cognitive rehabilitation (CR) on memory-related brain activation in […]

The present study (a) extended the assessment of an orientation program involving auditory cues (i.e., verbal messages automatically presented from the destinations) with five patients with Alzheimer’s disease, (b) compared the effects of this program with those of a program with light cues (i.e., a program in which strobe lights were used instead of the […]
