Visual perception has been shown to be altered in Alzheimer disease (AD) patients, and it is associated with decreased cognitive function. Galantamine is an active cholinergic agent, which has been shown to lead to improved cognition in mild to moderate AD patients. This study examined brain activation in a group of mild AD patients after […]

Heindel, William C.
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) […]
Semantic memory training in Alzheimer’s disease
The purpose of this study was to assess the effects of semantic stimulation of Alzheimer’s patients on semantic memory comparatively to psychological support. We conducted semantic training with two target categories (musical instruments and human actions), because these concepts were massively failed in previous data collected in Alzheimer’s disease. Ten patients (57-78 year old, MMSE […]

Objective: This study aims to evaluate whether assessing memory using the visual recognition memory task DMS48 in amnestic mild cognitive impairment (aMCI) can contribute to the early diagnosis of Alzheimer’s disease (AD). In an 18-month follow-up study, we assessed if longitudinal change in aMCI patients who failed on the DMS48 differs from that of patients […]
