Accumulation of phospholipid hydroperoxide (PLOOH) in erythrocyte membranes is an abnormality found in patients with senile dementia, including those with Alzheimer’s disease. In our previous studies, dietary xanthophylls (polar carotenoids such as lutein) were hypothesized to inhibit lipid peroxidation. In the present study, we conducted a randomized, double-blind, placebo-controlled human trial to assess the impact […]

Jacobsen, Janice
Background: Evidence supports a role of α4β2 receptors in Alzheimer’s disease (AD).; Methods: This Korean, multicenter, double-blind, two-period (6 weeks each), crossover study randomized participants to the order in which they received varenicline (1 mg twice daily) and placebo. Assessments included AD Assessment Scale-Cognitive Subscale (ADAS-Cog) 75, Neuropsychiatric Inventory (NPI), adverse events (AEs) and Columbia-Suicide […]
Cognitive effects of reducing anticholinergic drug burden in a frail elderly population: a randomized controlled trial
Kersten, H.,
Molden, E.,
Tolo, I. K.,
Skovlund, E.,
Engedal, K.,
Wyller, T. B.
Background: Observational studies report a relationship between anticholinergic drug scale (ADS) score and cognitive function. This study investigated whether a reduced ADS score improved cognitive function in a frail elderly population.; Methods: This randomized, controlled, single-blinded trial, recruited long-term residents with an ADS score of greater than or equal to 3 from 22 nursing homes […]
Demonstration of safety in Alzheimer’s patients for intervention with an anti-hypertensive drug Nilvadipine: results from a 6-week open label study

Mathura, V.,
Mullan, M.,
Crawford, F.,
Lawlor, B. A.,
Kenny, R. A.
Background: Nilvadipine may lower rates of conversion from mild-cognitive impairment to Alzheimer’s disease (AD), in hypertensive patients. However, it remains to be determined whether treatment with nilvadipine is safe in AD patients, given the higher incidence of orthostatic hypotension (OH) in this population, who may be more likely to suffer from symptoms associated with the […]
Population screening for variant Creutzfeldt-Jakob disease using a novel blood test: diagnostic accuracy and feasibility study

Mead, Simon,
Collinge, John
Importance: Our study indicates a prototype blood-based variant Creutzfeldt-Jakob disease (vCJD) assay has sufficient sensitivity and specificity to justify a large study comparing vCJD prevalence in the United Kingdom with a bovine spongiform encephalopathy-unexposed population. In a clinical diagnostic capacity, the assay’s likelihood ratios dramatically change an individual’s pretest disease odds to posttest probabilities and […]

Objectives: To study the effects of omega (Omega)-3 fatty acid (FA) supplements on weight and appetite in patients with mild to moderate Alzheimer’s disease (AD) in relation to inflammatory biomarkers and apolipoprotein E epsilon4 (APOEepsilon4).; Design: Randomized, double-blind, placebo-controlled trial.; Setting: Specialist memory clinics in the Stockholm catchment area.; Participants: Two hundred four patients (aged […]
Ankle blood pressure and dementia: a prospective follow-up study
Background and Objective: Ankle blood pressure may be a useful indicator of arterial stiffness. The main aim of the present study was to examine the relationship of ankle blood pressure measured in midlife with the risk of dementia with advancing age. A secondary aim was to examine the relationship of physical exercise capacity in midlife […]
Antihypertensive therapy and cerebral hemodynamics in executive mild cognitive impairment: results of a pilot randomized clinical trial

Mack, Wendy,
Novak, Vera,
C. Chui, Helena,
Lipsitz, Lewis
Objectives: To compare the effects of three antihypertensive medications on cerebral hemodynamic and cognitive function in hypertensive individuals with executive dysfunction.; Design: Double-blind randomized clinical trial.; Setting: Community.; Participants: Fifty-three individuals aged 60 and older with hypertension and executive dysfunction.; Intervention: Lisinopril, candesartan, or hydrochlorothiazide for 1 year.; Measurements: Cerebral blood flow velocity (BFV; transcranial […]
Plasma proteomics for the identification of Alzheimer disease
Less-invasive biomarkers for early Alzheimer disease (AD) are urgently needed. The present study aimed to establish a panel of plasma proteins that accurately distinguishes early AD from physiological aging and to compare the findings with previous reports. Fifty-eight healthy controls (CON) and 109 patients with AD dementia were randomly split into a training (40%) and […]
