Preventing loss of independence through exercise (PLIE): a pilot clinical trial in older adults with dementia
Barnes, D. E.,
Mehling, W.,
Wu, E.,
Beristianos, M.,
Yaffe, K.,
Skultety, K.,
Chesney, M. A.
BACKGROUND: Current dementia medications have small effect sizes, many adverse effects and do not change the disease course. Therefore, it is critically important to study alternative treatment strategies. The goal of this study was to pilot-test a novel, integrative group exercise program for individuals with mild-to-moderate dementia called Preventing Loss of Independence through Exercise (PLIE), […]

Combination antiretroviral therapy (CART) has greatly reduced medical morbidity and mortality with HIV infection, but high rates of HIV-associated neurocognitive disorders (HAND) continue to be reported. Because large HIV-infected (HIV+) and uninfected (HIV-) groups have not been studied with similar methods in the pre-CART and CART eras, it is unclear whether CART has changed the […]
Effect of B vitamins and lowering homocysteine on cognitive impairment in patients with previous stroke or transient ischemic attack: a prespecified secondary analysis of a randomized, placebo-controlled trial and meta-analysis
Hankey, Graeme J.,

Almeida, Osvaldo P.,
van Bockxmeer, Frank M.
Background and Purpose: High plasma total homocysteine (tHcy) has been associated with cognitive impairment but lowering tHcy with B-vitamins has produced equivocal results. We aimed to determine whether B-vitamin supplementation would reduce tHcy and the incidence of new cognitive impairment among individuals with stroke or transient ischemic attack≥6 months previously.; Methods: A total of 8164 […]

Maier, Wolfgang,
Scherer, Martin
Background: Social support has been suggested to positively influence cognition and mortality in old age. However, this suggestion has been questioned due to inconsistent operationalisations of social support among studies and the small number of longitudinal studies available. This study aims to investigate the influence of perceived social support, understood as the emotional component of […]
Toward onset prevention of cognitive decline in adults with Down syndrome (the TOP-COG study): study protocol for a randomized controlled trial

Ring, Howard,
Starr, John,
Stiles, Ciara,
Sullivan, Frank
Background: Early-onset dementia is common in Down syndrome adults, who have trisomy 21. The amyloid precursor protein gene is on chromosome 21, and so is over-expressed in Down syndrome, leading to amyloid β (Aβ) over-production, a major upstream pathway leading to Alzheimer disease (AD). Statins (microsomal 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors), have pleiotropic effects including […]
Memantine for patients with Parkinson’s disease dementia or dementia with Lewy bodies: a randomised, double-blind, placebo-controlled trial
Emre, Murat,

Destée, Alain,
Tolosa, Eduardo,
Kutzelnigg, Alexandra,
Ceballos-Baumann, Andrés,
Zdravkovic, Slobodan,
Bladström, Anna,
Jones, Roy
Background: Previous studies have suggested that patients with Lewy-body-related dementias might benefit from treatment with the N-methyl D-aspartate receptor antagonist memantine, but further data are needed. Therefore, the efficacy and safety of memantine were investigated in patients with mild to moderate Parkinson’s disease dementia (PDD) or dementia with Lewy bodies (DLB).; Methods: Patients (≥50 years […]
The association of statin use and statin type and cognitive performance: analysis of the reasons for geographic and racial differences in stroke (REGARDS) study

Background: Statin use and type have been variably associated with impaired or improved cognitive performance.; Hypothesis: To assess the association of statin use and type (lipophilic vs hydrophilic) and cognitive impairment.; Methods: Cross-sectional analysis of 24 595 participants (7191 statin users and 17 404 nonusers) age > or = 45 years, from a population-based national […]
Commentary on “A roadmap for the prevention of dementia II. Leon Thal Symposium 2008.” The Multidomain Alzheimer Preventive Trial (MAPT): a new approach to the prevention of Alzheimer’s disease
Gillette-Guyonnet, Sophie,

Dantoine, Thierry,
Dartigues, Jean-François,
Touchon, Jacques,
Vellas, B.
Background: Because no effective curative approaches are available, preventive approaches in the field of Alzheimer’s disease (AD) are needed. We present the design of the ongoing Multidomain Alzheimer Preventive Trial (MAPT) Study. Several previous studies suggested that many factors may be involved in the occurrence of AD at late ages. Because of the probable multifactorial […]
Can a tailored exercise and home hazard reduction program reduce the rate of falls in community dwelling older people with cognitive impairment: protocol paper for the i-FOCIS randomised controlled trial

Background: The rate of falls in community dwelling older people with cognitive impairment (CI) is twice that of a cognitively intact population, with almost two thirds of people with CI falling annually. Studies indicate that exercise involving balance and/or a home hazard reduction program are effective in preventing falls in cognitively intact older people. However […]
