Alzheimer’s disease multiple intervention trial (ADMIT): study protocol for a randomized controlled clinical trial
Background: Given the current lack of disease-modifying therapies, it is important to explore new models of longitudinal care for older adults with dementia that focus on improving quality of life and delaying functional decline. In a previous clinical trial, we demonstrated that collaborative care for Alzheimer’s disease reduces patients’ neuropsychiatric symptoms as well as caregiver […]

A proteomics study reveals a predominant change in MaoB expression in platelets of healthy volunteers after high protein meat diet: relationship to the methylation cycle
Studies investigating the impact of high meat intake on cognition have yielded contradictory results as some show improved cognitive performance, whereas others report an increase of risk factors for dementia. However, few studies were designed to directly assess the effect of a high protein (HP) diet on both cognitive performance and corresponding biochemical parameters. A […]

DHEA and cognition in HIV-positive patients with non-major depression
Background: Dihydroepiandrosterone (DHEA) has been investigated for its potential role in improving cognition in a number of patient populations. Treatment options are limited for HIV-associated neurocognitive disorders.; Objective: The authors tested the effect of DHEA administration on the cognitive functioning of HIV-positive subjects with non-major depression.; Method: The neuropsychological testing data for 60 HIV-positive patients […]

The effects on cognitive functions of a movement-based intervention in patients with Alzheimer’s type dementia: a pilot study
Objective: To explore the effect of a non-aerobic movement based activity on cognition in people with Alzheimer’s type dementia (AD).; Methods: The sample consisted of 27 patients fulfilling the AD ICD-10 diagnostic criteria. The patient sample was randomly divided into two groups: The Exercise Group received 6 weeks movement training and comprised 15 participants with […]

Effects of n-3 fatty acids on cognitive decline: a randomized, double-blind, placebo-controlled trial in stable myocardial infarction patients
Background: Epidemiological studies suggest a protective effect of n-3 fatty acids derived from fish (eicosapentaenoic acid [EPA] and docosahexaenoic acid [DHA]) against cognitive decline. For α-linolenic acid (ALA) obtained from vegetable sources, the effect on cognitive decline is unknown. We examined the effect of n-3 fatty acid supplementation on cognitive decline in coronary heart disease […]

Effects of DHA-phospholipids, melatonin and tryptophan supplementation on erythrocyte membrane physico-chemical properties in elderly patients suffering from mild cognitive impairment
A randomized, double-blind placebo-controlled clinical trial was carried out to assess the efficacy of a docosahexenoic acid (DHA)-phospholipids, melatonin and tryptophan supplemented diet in improving the erythrocyte oxidative stress, membrane fluidity and membrane-bound enzyme activities of elderly subjects suffering from mild cognitive impairment (MCI). These subjects were randomly assigned to the supplement group (11 subjects, […]

Transdermal is better than oral: observational research of the satisfaction of caregivers of patients with Alzheimer’s disease treated with rivastigmine
Background and Aims: Poor adherence to anti-dementia drugs is common among patients with Alzheimer’s disease. This study evaluated whether caregivers were more satisfied with, and patients more adherent to, transdermal rivastigmine than oral rivastigmine.; Methods: Neurologists, psychiatrists and geriatricians collected sociodemographic and clinical data from 1,078 patients and administered the Treatment Satisfaction with Medicines (SATMED-Q) […]

Reduction of hippocampal hyperactivity improves cognition in amnestic mild cognitive impairment
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 […]

Is high oral dose L-arginine intake effective in leukoaraiosis? Preliminary data, study protocol and expert’s opinion
Background: Leukoraraiosis is worldwide considered as a part of the normal aging process, although it is strongly associated with dementia and other disabilities. The pathogenesis of leukoaraiosis still has not been thoroughly acknowledged, even though chronic ischemia with consequent arteriolosclerosis probably due to endothelial dysfunction has been suggested. Treatment focuses on prevention of lesion formation […]

Factors associated with sustained attention during an activity intervention in persons with dementia
Background/aims: Are the noncognitive factors of self-reported mood and personality related to sustained attention in nursing home residents with dementia during an activity intervention?; Methods: Intervention data from a randomized clinical trial were used to address the aim of this project. Subjects were 128 nursing home residents who were assessed for mood, personality, behavioral indicators […]
