Methodological issues in a cluster-randomized trial to prevent dementia by intensive vascular care
Objectives: Description of methodological issues in a trial designed to evaluate if a multi-component intervention aimed at vascular risk factors can prevent dementia.; Design, Setting and Participants: Multi-center, open, cluster-randomized controlled clinical trial (preDIVA) including 3535 non-demented subjects aged 70-78, executed in primary practice and coordinated from one academic hospital. General practices are randomized to […]

Background: Even effective interventions for people with dementia and their caregivers require specific implementation efforts. A pilot study showed that the highly effective community occupational therapy in dementia (COTiD) program was not implemented optimally due to various barriers. To decrease these barriers and make implementation of the program more effective a combined implementation (CI) strategy […]

Objective: We compared the ability of arterial spin labeling (ASL), an MRI method that measures cerebral blood flow (CBF), to that of FDG-PET in distinguishing patients with Alzheimer disease (AD) from healthy, age-matched controls.; Methods: Fifteen patients with AD (mean age 72 ± 6 years, Mini-Mental State Examination score [MMSE] 20 ± 6) and 19 […]

This study assessed whether three patients with Alzheimer’s disease could learn to use a basic orientation technology to reach different rooms within a day center. At each travel instance, the technology provided verbal messages (cues) from the room to reach. For the first two patients, the messages were presented at intervals of about 15s. For […]

This study examined the effects of Behavioral Activation (BA) treatment on depressive symptoms and quality of life among older adult patients in a geriatric psychiatry facility. There were 50 participants with mild to moderate cognitive impairment, each being 65 years of age or older. A 2 (between)×3 (time of measurement) design was used in this […]

Murthy, Anita
A magnetic resonance imaging (MRI) study was conducted as part of an intervention study in subjects with amnestic mild cognitive impairment (aMCI) to assess donepezil’s treatment effect on brain atrophy. Adults with aMCI were randomly assigned to double-blind treatment with 10 mg/day donepezil hydrochloride or placebo for 48 weeks. Brain MRI scans were acquired at […]

Cognitive training changes hippocampal function in mild cognitive impairment: a pilot study
A randomized pilot experiment examined the neural substrates of response to cognitive training in participants with mild cognitive impairment (MCI). Participants performed exercises previously demonstrated to improve verbal memory and an active control group performed other computer activities. An auditory-verbal fMRI task was conducted before and after the two-month training program. Verbal memory scores improved […]
