Cognition and function in Alzheimer’s disease: identifying the transitions from moderate to severe disease
Background/aims: Cognitive and functional decline define the transition from moderate to severe Alzheimer’s disease (AD); however, specific relationships between deteriorating cognition and functional abilities are less well characterized. Such relationships are important in care planning and understanding patient needs. Objectives of this post hoc analysis of data from a multicenter randomized double-blind placebo-controlled study were […]
Cognitive training changes hippocampal function in mild cognitive impairment: a pilot study
A randomized pilot experiment examined the neural substrates of response to cognitive training in participants with mild cognitive impairment (MCI). Participants performed exercises previously demonstrated to improve verbal memory and an active control group performed other computer activities. An auditory-verbal fMRI task was conducted before and after the two-month training program. Verbal memory scores improved […]
Qualitative analysis of therapeutic light effects on global function in Alzheimer’s disease
The occurrence of Alzheimer’s disease (AD) is growing, with 68% of cases occurring in women. Declines in global function exacerbated by reversal of day-night patterns, disturbed sleep-wake rhythms, and excessive daytime sleepiness make managing AD difficult. In this study, the authors examined the effect and duration of effect of therapeutic light on sleep, rest-activity, and […]

Pan, P. C.,
Yung, C. Y.,
Choi, K. C.,
Lam, L. C.
Introduction: Whether homocysteine lowering by B vitamins can reduce cognitive decline in Alzheimer disease and vascular dementia patients is unclear.; Methods and Materials: 140 subjects with mild to moderate Alzheimer disease or vascular dementia were randomly assigned to take 1 mg of methylcobalamin and 5 mg of folic acid, or placebo once daily for 24 […]

Blennow, K.,
Minthon, L.
Objectives: To explore the longitudinal stability of measures of cognition during treatment with acetylcholinesterase inhibitors (AchEI) in patients with Alzheimer’s disease (AD).; Materials and Methods: Cognitive status was measured in a cohort of 60 patients at 6 months after initiation of treatment with AchEI (baseline) and after an additional 6 months of treatment (endpoint). A […]

Background and Purpose: We sought to assess the efficacy and safety of donepezil in patients with vascular dementia (VaD) fulfilling National Institute of Neurological Disorders and Stroke-Association Internationale pour la Recherche et l’Enseignement en Neurosciences criteria.; Methods: This international, multicenter, 24-week trial was conducted from March 2003 to August 2005. Patients (N=974; mean age, 73.0 […]
Effects of rivastigmine on common symptomatology of Alzheimer’s disease (EXPLORE)
Objective: To evaluate, in a real-world clinical setting, the efficacy of rivastigmine in the management of six symptoms commonly associated with Alzheimer’s disease (AD).; Methods: This was a naturalistic, prospective, open-label, multi-centre, post-marketing, observational study. Data were collected by the participating study physicians at their practices across Canada. Subjects had a clinical diagnosis of mild-to-moderate […]
