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 […]

Andrews, Karen,
Sano, Mary
Objective: Longitudinal neuropsychological assessment provides the opportunity to observe the earliest transition to cognitive impairment in healthy, elderly individuals. We examined the feasibility, and its comparability to in-person assessment, of a telephone administered battery of established neuropsychological measures of cognitive functioning in healthy, elderly women.; Methods: Fifty-four women (age = 79 +/- 7.7; education = […]

Pelosi, Annalisa,
Pazzaglia, Francesca,
Caffarra, Paolo
Spatial abilities decline in normal aging and decrease faster and earlier in Alzheimer’s disease (AD), but these deficits are under investigated. The main goals of this study were to assess visuospatial memory abilities in mild cognitive impairment (MCI), in order to verify whether these tasks might be valid as the standard cognitive test to differentiate […]
Effect of a computerized brain exercise program on cognitive performance in older adults
Miller, Karen J.,
Dye, Richelin V.,
Kim, Jeanne,
Jennings, Julia L.,
O'Toole, Elizabeth,
Wong, Julie,
Siddarth, Prabha
Objectives: Research indicates an association between stimulating mental activities and better memory performance as people age, but studies on computerized mental stimulation programs are limited. We explored whether computerized brain training exercises improved cognitive performance in older adults.; Methods: In local retirement communities, a convenience sample was randomized into an intervention group (N = 36), […]
Turning back the hands of time: Autobiographical memories in dementia cued by a museum setting
The current study examined the effects of cuing autobiographical memory retrieval in 12 older participants with dementia through immersion into a historically authentic environment that recreated the material and cultural context of the participants’ youth. Participants conversed in either an everyday setting (control condition) or a museum setting furnished in early twentieth century style (experimental […]

Treatment of Alzheimer’s disease (AD) with acetylcholinesterase inhibitors (AChEI) enhances cholinergic activity and alleviates clinical symptoms. In the present functional magnetic resonance imaging (fMRI) study, we investigated the effect of the AChEI rivastigmine on cognitive function and brain activation patterns during a face recognition memory task. Twenty patients with newly-diagnosed mild AD were administered a […]

Objective: To evaluate the cost-effectiveness of post-diagnosis dementia treatment and coordination of care by memory clinics compared to general practitioners’ care.; Methods: A multicentre randomised trial with 175 community dwelling patients newly diagnosed with mild to moderate dementia, and their informal caregivers, with twelve months’ follow-up. Cost-effectiveness was evaluated from a societal point of view […]
A comparison of neuropsychiatric and cognitive profiles in delirium, dementia, comorbid delirium-dementia and cognitively intact controls
Meagher, D. J.,
Leonard, M.,
Donnelly, S.,
Conroy, M.,
Saunders, J.,
Trzepacz, P. T.
Purpose: Delirium and dementia have overlapping features that complicate differential diagnosis. Delirium symptoms overshadow dementia symptoms when they co-occur, but delirium phenomenology in comorbid cases has not been compared to both conditions alone.; Methods: Consecutive adults with DSM-IV delirium, dementia, comorbid delirium-dementia and cognitively intact controls were assessed using the Revised Delirium Rating Scale (DRS-R98) […]
Specialist mental health consultation for depression in Australian aged care residents with dementia: a cluster randomized trial
McSweeney, Kate,
Jeffreys, Aimee,
Griffith, Joanne,
Plakiotis, Chris,
Kharsas, Renee,
O'Connor, Daniel W.
Objective: This cluster randomized controlled trial sought to determine whether multidisciplinary specialist mental health consultation was more effective than care as usual in treating the depression of aged care residents with dementia.; Methods: Three hundred and eighty nine aged care residents were screened for dementia and major depression. Forty four were ultimately included in the […]
