Effects of cranial electrical stimulation on sleep disturbances, depressive symptoms, and caregiving appraisal in spousal caregivers of persons with Alzheimer’s disease

Purpose: The purpose of this work was to investigate the effects of cranial electrical stimulation (CES) on sleep disturbances, depressive symptoms, and caregiving appraisal.; Methods: Thirty-eight participants were randomly assigned to receive active CES or sham CES for 4 weeks.; Results: Both intervention groups demonstrated improvement in study measures from baseline scores. A trend toward […]

The effects of glucose ingestion and glucose regulation on memory performance in older adults with mild cognitive impairment

Background/objectives: Previous research investigating the impact of glucose ingestion and/or improvements in glucose regulation has found selective cognitive facilitation on episodic memory tasks in successful ageing and dementia. The present study aimed to extend this research to mild cognitive impairment (MCI).; Subjects/methods: In a repeated-measures design, 24 older adults with and 24 older adults without […]

A randomized, double-blind, placebo-controlled tolerability study of intramuscular aripiprazole in acutely agitated patients with Alzheimer’s, vascular, or mixed dementia

Objectives: To evaluate the tolerability of intramuscular (IM) aripiprazole in patients with agitation associated with dementia.; Design: A 24-hour, double-blind, placebo-controlled, randomized study.; Setting: Sixteen healthcare facilities in the United States.; Participants: A total of 129 patients with acute agitation associated with Alzheimer’s, vascular or mixed dementia in healthcare facilities.; Intervention: Patients were randomized to […]

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 […]

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 […]

Donepezil delays progression to AD in MCI subjects with depressive symptoms

Objective: To determine whether the presence of depression predicts higher rate of progression to Alzheimer disease (AD) in patients with amnestic mild cognitive impairment (aMCI) and whether donepezil treatment beneficially affect this relationship.; Methods: The study sample was composed of 756 participants with aMCI from the 3-year, double-blind, placebo-controlled Alzheimer’s Disease Cooperative Study drug trial […]

Vitamin E paradox in Alzheimer’s disease: it does not prevent loss of cognition and may even be detrimental

There is controversy as to whether vitamin E is beneficial in Alzheimer’s disease (AD). In this study, we tested if vitamin E prevents oxidative stress and loss of cognition in AD. Fifty-seven AD patients were recruited and divided in two groups: placebo or treated with 800 IU of vitamin E per day for six months. […]

Using acupressure and Montessori-based activities to decrease agitation for residents with dementia: a cross-over trial

Objectives: To explore the effectiveness of acupressure and Montessori-based activities in decreasing the agitated behaviors of residents with dementia.; Design: A double-blinded, randomized (two treatments and one control; three time periods) cross-over design was used.; Setting: Six special care units for residents with dementia in long-term care facilities in Taiwan were the sites for the […]

Randomized controlled trial of memantine in dementia associated with Parkinson’s disease

The objective of this study is to investigate the safety and tolerability of memantine, a glutamatergic modulator, in patients suffering from dementia associated with Parkinson’s disease (PDD), an increasingly common complication of PD. This was a 22-week trial of 25 participants with a DSM-IV diagnosis of PDD who were randomized to either placebo or 20 […]
