Differential perceptions of quality of life (QoL) in community-dwelling persons with mild-to-moderate dementia

Background: Discordance between patient- and caregiver-reported quality of life (QoL) is well recognized. This study sought to (i) identify predictors of discrepancy between patient- and caregiver-rated QoL amongst community-dwelling persons with mild-to-moderate dementia, and (ii) differentiate between patients who systematically rate their QoL lower versus those who rate their QoL higher relative to their caregiver […]

Infection hospitalization increases risk of dementia in the elderly

Objectives: Severe infections, often requiring ICU admission, have been associated with persistent cognitive dysfunction. Less severe infections are more common and whether they are associated with an increased risk of dementia is unclear. We determined the association of pneumonia hospitalization with risk of dementia in well-functioning older adults.; Design: Secondary analysis of a randomized multicenter […]

A randomized controlled trial of high-dose vitamin D2 followed by intranasal insulin in Alzheimer’s disease

Poor vitamin D nutrition is linked with dementia, but vitamin D has not been tested in a randomized controlled trial (RCT) in Alzheimer’s disease (AD). Nasal insulin acutely improves cognition and vitamin D upregulates insulin receptor expression and enhances insulin action. In an RCT we examined the effect of high-dose vitamin D followed by nasal […]

Angiotensin-converting enzyme inhibitors and Alzheimer’s disease progression in older adults: results from the Réseau sur la Maladie d’Alzheimer Français cohort

Objectives: To assess whether angiotensin-converting enzyme inhibitor (ACE-I) treatment is associated with less cognitive decline in older adults with Alzheimer’s disease (AD) than in those using other hypertensive or no drugs.; Design: Four-year prospective multicenter cohort study with a biannual assessment.; Setting: Memory clinics from 16 university hospitals in France.; Participants: Community-dwelling older adults with […]

Cognitive subdomain responses to galantamine in Alzheimer’s disease

We investigated the effects of galantamine on cognitive subdomains in Alzheimer’s disease (AD). Sixty-six patients with mild-to-moderate AD received open-label galantamine for 52 weeks. Cognitive function was measured using the Korean version of the Alzheimer’s Disease Assessment Scale-cognitive subscale (ADAS-cog-K). Response to galantamine was defined as “improvement or no deterioration” on the total scores of […]

25-Hydroxyvitamin D levels and cognitive performance and decline in elderly men

Objective: To test the hypothesis that lower 25-hydroxyvitamin D [25(OH)D] levels are associated with a greater likelihood of cognitive impairment and risk of cognitive decline.; Methods: We measured 25(OH)D and assessed cognitive function using the Modified Mini-Mental State Examination (3MS) and Trail Making Test Part B (Trails B) in a cohort of 1,604 men enrolled […]

Angiotensin-converting enzyme inhibitors and cognitive decline in older adults with hypertension: results from the Cardiovascular Health Study

Background: Hypertension (HTN) is a risk factor for dementia, and animal studies suggest that centrally active angiotensin-converting enzyme (ACE) inhibitors (those that cross the blood-brain barrier) may protect against dementia beyond HTN control.; Methods: Participants in the Cardiovascular Health Study Cognition Substudy with treated HTN and no diagnosis of congestive heart failure (n = 1054; […]

Cognitive dysfunction in HIV patients despite long-standing suppression of viremia

Objective: To determine the prevalence of cognitive complaints and HIV-associated neurocognitive disorders (HANDs) in a cohort of aviremic HIV-positive patients. To evaluate the relevance of the HIV dementia scale to detect HANDs.; Design: Assessment of HANDs with neuropsychological tests.; Methods: Two hundred HIV-infected patients with undetectable HIV-1 RNA concentrations in the plasma, no history of […]

A randomized placebo-controlled pilot trial of omega-3 fatty acids and alpha lipoic acid in Alzheimer’s disease

Oxidative stress, inflammation, and increased cholesterol levels are all mechanisms that have been associated with Alzheimer’s disease (AD) pathology. Several epidemiologic studies have reported a decreased risk of AD with fish consumption. This pilot study was designed to evaluate the effects of supplementation with omega-3 fatty acids alone (ω-3) or omega-3 plus alpha lipoic acid […]

Postoperative medical complications associated with anesthesia in older adults with dementia

Objectives: To examine the association between anesthetic technique and postoperative complications in older adults with dementia undergoing hip fracture surgery.; Design: Population-based, retrospective cohort study.; Setting: Ontario, Canada.; Participants: All older adults with dementia who underwent surgery for hip fracture repair in Ontario, Canada, between April 1, 2003 and March 31, 2011.; Measurements: The baseline […]
