Methodological improvements in quantifying cognitive change in clinical trials: an example with single-dose administration of donepezil

Objectives: Change in cognitive function in response to a pharmacologic challenge can be observed with greater sensitivity by employing cognitive tests with optimal psychometric properties and a statistical approach that more accurately accounts for individual variability in performance. To demonstrate this approach we examined the cognitive effects of a single acute dose administration of an […]

Effects of donepezil on cortical activation in mild cognitive impairment: a pilot double-blind placebo-controlled trial using functional MR imaging

Background and Purpose: Cholinesterase-inhibitor therapy is approved for treatment of Alzheimer disease; however, application in patients with mild cognitive impairment (MCI) is still under active investigation. The purpose of this study was to determine the effect of such therapy on the neural substrates underlying memory processing in subjects with MCI by using functional MR imaging […]

A randomized controlled study on effects of ibuprofen on cognitive progression of Alzheimer’s disease

Background and Aims: Epidemiological studies have examined the association between the use of non-steroidal anti-inflammatory drugs (NSAIDs) and the risk of Alzheimer’s disease (AD). Recently, a variety of experimental studies indicates that a subset of NSAIDs, such as ibuprofen or flurbiprofen, also have Abeta-lowering properties in both AD transgenic mice and cell cultures of peripheral, […]

Spaced retrieval significantly improves prospective memory performance of cognitively impaired older adults

Background: Although memory for future intentions (prospective memory, PM) is compromised in older adults with cognitive impairment, the effectiveness of specific training techniques to help these older adults with PM tasks remains unclear.; Objective: The present study examined the effectiveness of spaced retrieval (rehearsing at increasingly spaced intervals) as an intervention for improving PM in […]

Different cholinesterase inhibitor effects on CSF cholinesterases in Alzheimer patients

Background: The current study aimed to compare the effects of different cholinesterase inhibitors on acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) activities and protein levels, in the cerebrospinal fluid (CSF) of Alzheimer disease (AD) patients.; Methods and Findings: AD patients aged 50-85 years were randomized to open-label treatment with oral rivastigmine, donepezil or galantamine for 13 weeks. […]

Efficacy and tolerability of Ginkgo biloba extract EGb 761 by type of dementia: analyses of a randomised controlled trial

Secondary analyses of a randomised controlled trial were performed to find out whether treatment effects of Ginkgo biloba extract EGb 761 differed by type of dementia. Three hundred ninety-five patients aged 50 years or above, with dementia with neuropsychiatric features were treated with EGb 761 (240 mg/day) or placebo for 22 weeks. Patients scored between […]

Mobility training after hip fracture: a randomised controlled trial

Objective: to compare the effects of two different exercise programmes after hip fracture.; Design: assessor-blinded randomised controlled trial.; Setting: hospital rehabilitation units, with continued intervention at home.; Subjects: 160 people with surgical fixation for hip fracture transferred to inpatient rehabilitation.; Method: in addition to other rehabilitation strategies, the intervention group received a higher dose (60 […]

Improving effects of the mushroom Yamabushitake (Hericium erinaceus) on mild cognitive impairment: a double-blind placebo-controlled clinical trial

A double-blind, parallel-group, placebo-controlled trial was performed on 50- to 80-year-old Japanese men and women diagnosed with mild cognitive impairment in order to examine the efficacy of oral administration of Yamabushitake (Hericium erinaceus), an edible mushroom, for improving cognitive impairment, using a cognitive function scale based on the Revised Hasegawa Dementia Scale (HDS-R). After 2 […]

A randomized cross-over study of a traditional Japanese medicine (kampo), yokukansan, in the treatment of the behavioural and psychological symptoms of dementia

The effectiveness and safety of yokukansan (TJ-54), a traditional Japanese medicine (kampo) for the treatment of the behavioural and psychological symptoms of dementia (BPSD), were evaluated in 106 patients diagnosed as having Alzheimer’s disease (AD) (including mixed-type dementia) or dementia with Lewy bodies. Patients were randomly assigned to group A (TJ-54 treatment in period I […]

Effectiveness of a psychoeducational intervention program in the reduction of caregiver burden in Alzheimer’s disease patients’ caregivers

Objectives: Caregivers of patients with Alzheimer’s disease (AD) experience physical and psychological stress due to the caring experience. This study evaluated the benefits of a Psychoeducational Intervention Program (PIP) on caregiver burden in southern Europe.; Methods: A multicentre, prospective, randomised study was conducted. One hundred and fifteen caregivers of patients with clinical diagnosis of AD […]
