Vitamin E and memantine in Alzheimer’s disease: clinical trial methods and baseline data
Background: Alzheimer’s disease (AD) has been associated with both oxidative stress and excessive glutamate activity. A clinical trial was designed to compare the effectiveness of (i) alpha-tocopherol, a vitamin E antioxidant; (ii) memantine (Namenda), an N-methyl-D-aspartate antagonist; (iii) their combination; and (iv) placebo in delaying clinical progression in AD.; Methods: The Veterans Affairs Cooperative Studies […]

Prevention of depression and sleep disturbances in elderly with memory-problems by activation of the biological clock with light–a randomized clinical trial
Background: Depression frequently occurs in the elderly and in patients suffering from dementia. Its cause is largely unknown, but several studies point to a possible contribution of circadian rhythm disturbances. Post-mortem studies on aging, dementia and depression show impaired functioning of the suprachiasmatic nucleus (SCN) which is thought to be involved in the increased prevalence […]

Alzheimer’s disease–input of vitamin D with mEmantine assay (AD-IDEA trial): study protocol for a randomized controlled trial
Background: Current treatments for Alzheimer’s disease and related disorders (ADRD) are symptomatic and can only temporarily slow down ADRD. Future possibilities of care rely on multi-target drugs therapies that address simultaneously several pathophysiological processes leading to neurodegeneration. We hypothesized that the combination of memantine with vitamin D could be neuroprotective in ADRD, thereby limiting neuronal […]

Study of Mental Activity and Regular Training (SMART) in at risk individuals: a randomised double blind, sham controlled, longitudinal trial
Background: The extent to which mental and physical exercise may slow cognitive decline in adults with early signs of cognitive impairment is unknown. This article provides the rationale and methodology of the first trial to investigate the isolated and combined effects of cognitive training (CT) and progressive resistance training (PRT) on general cognitive function and […]

Sustainability of motor training effects in older people with dementia
Evidence for sustainability of motor training effects in people with dementia is lacking. To examine whether the substantial improvements in motor performance achieved through a three-month specialized, standardized motor training were sustained, the participants of the randomized controlled trial were re-evaluated nine months after training had ceased. As part of a comprehensive study, participants with […]

Memantine for AIDS dementia complex: open-label report of ACTG 301
Objective: To evaluate the long-term safety and efficacy of memantine use as treatment of HIV-associated cognitive impairment.; Background: The results of a 20-week, randomized, double-blind, placebo-controlled trial of memantine in HIV-infected participants with cognitive impairment (ACTG 301) were previously reported. We report the results of the up-to-60-week open-label phase following the double-blind phase.; Method: Participants […]

Improvement in memory with plasticity-based adaptive cognitive training: results of the 3-month follow-up
Objectives: To investigate maintenance of training effects of a novel brain plasticity-based computerized cognitive training program in older adults after a 3-month no-contact period.; Design: Multisite, randomized, controlled, double-blind trial with two treatment groups.; Setting: Communities in northern and southern California and Minnesota.; Participants: Four hundred eighty-seven community-dwelling adults aged 65 and older without diagnosis […]

The long-term efficacy and tolerability of donepezil in patients with vascular dementia
Objective: To determine the long-term tolerability and efficacy of donepezil in patients with vascular dementia (VaD).; Methods: International, multicentre, open-label, 30-week extension study of two 24-week, randomised, double-blind, placebo-controlled studies. Participants were ambulatory adults (59% female; mean age, 74.7 +/- 0.3) with a diagnosis of possible or probable VaD and without a diagnosis of Alzheimer’s […]

Randomised, multicentre, placebo-controlled, double-blind crossover study investigating the effect of solifenacin and oxybutynin in elderly people with mild cognitive impairment: the SENIOR study
Background: Compared with younger people, the elderly are more likely to suffer from overactive bladder (OAB) and to have other chronic conditions that affect physical or cognitive function. Despite this, there are few data on the cognitive safety of antimuscarinic agents in older patients and none that examine the effect of these agents on those […]

Memantine in behavioral variant frontotemporal dementia: negative results
We tested the efficacy and tolerability of one-year treatment with memantine (10 mg bid) in behavioral variant frontotemporal dementia (bvFTD). BvFTD patients aged 45 to 75 years, with a Mini-Mental Status Examination (MMSE) score ≥19, were enrolled in a national, randomized, double-blind, placebo-controlled (DBPC), Phase II trial. The primary endpoint was the CIBIC-Plus (Clinician’s Interview-Based […]
