Effects of atorvastatin on cerebral blood flow in middle-aged adults at risk for Alzheimer’s disease: a pilot study

Background/aims: Hypercholesterolemia in midlife increases risk for Alzheimer’s disease (AD) and contributes to cerebrovascular dysregulation – an early finding in preclinical AD pathology. Statins improve vascular reactivity, but it is unknown if they increase regional cerebral blood flow (CBF) in individuals at risk for AD.; Methods: In a randomized, controlled, double-blind pilot study, 16 asymptomatic […]

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 […]

Apolipoprotein E genotype-specific short-term cognitive benefits of treatment with the antihypertensive nilvadipine in Alzheimer’s patients–an open-label trial

Background: Evidence suggests that dihydropyridine calcium channel blockers may be useful in preventing and treating Alzheimer’s disease (AD).; Objective: In an open-label trial of safety and tolerability of nilvadipine in patients with AD, we examined cognition and executive function over a short time period to determine an influence of nilvadipine on these outcomes.; Method: We […]

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 […]

Effects of telmisartan on cognition and regional cerebral blood flow in hypertensive patients with Alzheimer’s disease

Aim: Recent studies have shown that some antihypertensive medications are associated with a significant reduction in the incidence of Alzheimer’s disease (AD). However, it remains uncertain whether antihypertensive drugs may have a preventive effect on cognitive decline in patients with AD. We investigated the effects of telmisartan, an angiotensin II type 1 receptor blocker with […]

Nicotine treatment of mild cognitive impairment: a 6-month double-blind pilot clinical trial

Objective: To preliminarily assess the safety and efficacy of transdermal nicotine therapy on cognitive performance and clinical status in subjects with mild cognitive impairment (MCI).; Methods: Nonsmoking subjects with amnestic MCI were randomized to transdermal nicotine (15 mg per day or placebo) for 6 months. Primary outcome variables were attentional improvement assessed with Connors Continuous […]

Donepezil for dementia with Lewy bodies: a randomized, placebo-controlled trial

Objective: Because cholinergic deficits are prominent in dementia with Lewy bodies (DLB), we investigated the effects of a cholinesterase inhibitor, donepezil, in such patients in a randomized, double-blind, placebo-controlled exploratory phase 2 trial.; Methods: One-hundred forty patients with DLB, recruited from 48 specialty centers in Japan, were randomly assigned to receive placebo or 3, 5, […]

Concord grape juice supplementation and neurocognitive function in human aging

Polyphenol compounds found in berry fruits, in particular flavonoids, have been associated with health benefits including improvement in cognition and neuronal function with aging. Concord grape juice contains polyphenols, including anthocyanins and flavanols, and previous research has shown improvement in a number of human health conditions with grape juice supplementation. In the current study, older […]

Dairy consumption and working memory performance in overweight and obese adults

All individuals will experience some degree of cognitive impairment in their later years. Diet is one readily modifiable factor that may influence cognitive function and psychological well-being. Very little research has considered the potential role of dairy foods in modulating cognitive and psychological functions. The objective of this study was to determine the effect of […]

Longitudinal changes of fractional anisotropy in Alzheimer’s disease patients treated with galantamine: a 12-month randomized, placebo-controlled, double-blinded study

Diffusion tensor imaging (DTI) demonstrates decline of fractional anisotropy (FA) as a marker of fiber tract integrity in Alzheimer’s disease (AD). We aimed to assess the longitudinal course of white matter microstructural changes in AD and healthy elderly control (HC) subjects and to evaluate the effects of treatment with the cholinesterase inhibitor galantamine on white […]
