Study protocol for the recreational stimulation for elders as a vehicle to resolve delirium superimposed on dementia (Reserve For DSD) trial

Background: Delirium is a state of confusion characterized by an acute and fluctuating decline in cognitive functioning. Delirium is common and deadly in older adults with dementia, and is often referred to as delirium superimposed on dementia, or DSD. Interventions that treat DSD are not well-developed because the mechanisms involved in its etiology are not […]

Efficacy of rivastigmine on executive function in patients with Parkinson’s disease dementia

Background and Objective: Rivastigmine is approved in the USA for the treatment of mild to moderate Alzheimer’s disease and Parkinson’s disease dementia (PDD). Executive function (EF) deficits are a core symptom of PDD. The current objective was to investigate the effects of rivastigmine capsules versus placebo on EF in PDD, focusing on secondary outcome measures […]

Is emotional memory enhancement preserved in amnestic mild cognitive impairment? Evidence from separating recollection and familiarity

Objective: This study investigated whether the observed absence of emotional memory enhancement in recognition tasks in patients with amnestic mild cognitive impairment (aMCI) could be related to their greater proportion of familiarity-based responses for all stimuli, and whether recognition tests with emotional items had better discriminative power for aMCI patients than those with neutral items.; […]

Treadmill training as an augmentation treatment for Alzheimer’s disease: a pilot randomized controlled study

Objective: To assess the effect of aerobic exercise on the cognition and functional capacity in Alzheimer’s disease (AD) patients.; Method: Elderly (n=20) with mild dementia (NINCDS-ADRDA/CDR1) were randomly assigned to an exercise group (EG) on a treadmill (30 minutes, twice a week and moderate intensity of 60% VO₂max) and control group (GC) 10 patients. The […]

Aerobic exercise improves cognition for older adults with glucose intolerance, a risk factor for Alzheimer’s disease

Impaired glucose regulation is a defining characteristic of type 2 diabetes mellitus (T2DM) pathology and has been linked to increased risk of cognitive impairment and dementia. Although the benefits of aerobic exercise for physical health are well-documented, exercise effects on cognition have not been examined for older adults with poor glucose regulation associated with prediabetes […]

The effect of group-based exercise on cognitive performance and mood in seniors residing in intermediate care and self-care retirement facilities: a randomised controlled trial

Objective: To determine the effect of a general group-based exercise programme on cognitive performance and mood among seniors without dementia living in retirement villages.; Design: Randomised controlled trial.; Setting: Four intermediate care and four self-care retirement village sites in Sydney, Australia.; Participants: 154 seniors (19 men, 135 women; age range 62 to 95 years), who […]

Effects of cholinesterase inhibitors on visual attention in drivers with Alzheimer disease

Objective: We conducted a combined observational cohort and case-control study in patients with Alzheimer disease (AD) to assess the effects of acetylcholinesterase inhibitor (ChEI) treatment on cognitive functions important for driving.; Methods: Performance of 24 outpatients with newly diagnosed (untreated) early-stage AD was compared before beginning ChEI (pre-ChEI) and after 3 months of therapy (post-ChEI) […]

Cognitive activity for the treatment of older adults with mild Alzheimer’s disease (AD)–PACE AD: study protocol for a randomised controlled trial

Background: Participation in cognitive stimulation therapy (CST) may reduce the rate of cognitive decline in people with Alzheimer’s disease (AD), however it is unclear if the training of carers to deliver activities is sufficient to improve the clinical outcome of patients. The Promoting Healthy Ageing with Cognitive Exercise for Alzheimer’s Disease (PACE-AD) study has been […]

Influence of memory strategies on memory test performance: a study in healthy and pathological aging

The ability to generate memory strategies is a key factor in the performance of episodic memory tasks. Whether the ability to generate memory strategies exerts an influence in the performance of memory tests in the elderly population is still a matter of debate. Here we present results from an experimental memory task (Test of Memory […]

Perseverative errors on the Wisconsin Card Sorting Test and brain perfusion imaging in mild Alzheimer’s disease

Background: The Wisconsin Card Sorting Test (WCST) has long been used to investigate deficits in executive function in humans. The majority of studies investigating deficient WCST performance focused on the number of categories achieved (CA) and the number of perseverative errors of the Nelson type (PEN). However, there is insufficient evidence that these two measures […]
