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 […]

Physical training improves motor performance in people with dementia: a randomized controlled trial

Objectives: To determine whether a specific, standardized training regimen can improve muscle strength and physical functioning in people with dementia.; Design: Double-blinded, randomized, controlled trial with 3-month intervention and 3-month follow-up period in 2006 to 2009.; Setting: Outpatient geriatric rehabilitation.; Participants: Individuals with confirmed mild to moderate dementia, no severe somatic or psychological disease, and […]

Effects of liraglutide on neurodegeneration, blood flow and cognition in Alzheimer´s disease – protocol for a controlled, randomized double-blinded trial

Introduction: Type 2 diabetes (DM-2) increases the risk of developing Alzheimer´s disease (AD), and patients with AD are more likely to develop DM-2. DM-2 and AD share some pathophysiological features. In AD, amyloid-β (Aβ) is accumulated as extracellular plaques in the gray matter of the brain, while in DM-2 islet amyloid polypeptide (IAPP) is accumulated […]

Tolerability of extended-release quetiapine fumarate compared with immediate-release quetiapine fumarate in older patients with Alzheimer’s disease with symptoms of psychosis and/or agitation: a randomised, double-blind, parallel-group study

Objective: The objective of this study was to assess the safety and tolerability of extended-release quetiapine fumarate (quetiapine XR) compared with quetiapine immediate-release (quetiapine IR) in older patients with Alzheimer’s disease with symptoms of psychosis and/or agitation.; Methods: This was a 6-week, double-blind, double-dummy, randomised study. Of the 109 patients screened, 100 were randomised to […]

A benefit-finding intervention for family caregivers of persons with Alzheimer disease: study protocol of a randomized controlled trial

Background: Caregivers of relatives with Alzheimer’s disease are highly stressed and at risk for physical and psychiatric conditions. Interventions are usually focused on providing caregivers with knowledge of dementia, skills, and/or support, to help them cope with the stress. This model, though true to a certain extent, ignores how caregiver stress is construed in the […]

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, […]

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 […]

Safety and pharmacology of ponezumab (PF-04360365) after a single 10-minute intravenous infusion in subjects with mild to moderate Alzheimer disease

Objective: Ponezumab (PF-04360365) is a humanized anti-amyloid beta (Aβ) monoclonal antibody designed for treatment of Alzheimer disease (AD). A single 2-hour intravenous infusion of 0.1 to 10 mg/kg was previously shown to be safe and well tolerated in subjects with mild to moderate AD, with measurable effects on plasma and cerebrospinal fluid Aβ. This phase […]

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 […]

Effect of immunotherapy with bapineuzumab on cerebrospinal fluid biomarker levels in patients with mild to moderate Alzheimer disease

Background: Given the slow and variable clinical course of Alzheimer disease, very large and extended clinical trials are needed to identify a beneficial clinical effect of disease-modifying treatments. Therefore, biomarkers are essential to prove that an anti-β-amyloid (Aβ) drug candidate affects both Aβ metabolism and plaque load as well as downstream pathogenic mechanisms.; Objective: To […]
