The PACE study: a randomized clinical trial of cognitive activity strategy training for older people with mild cognitive impairment

Objective: The role of cognition-focused interventions in reducing cognitive decline in older people remains uncertain. This study aimed to clarify whether a group cognitive activity (CA) strategy-training program would decrease the 2-year rate of cognitive decline of people with mild cognitive impairment (MCI).; Design: Randomized controlled trial.; Setting: One study site.; Participants: 160 older adults […]

A serum protein-based algorithm for the detection of Alzheimer disease

Objective: To develop an algorithm that separates patients with Alzheimer disease (AD) from controls. Design: Longitudinal case-control study. Setting: The Texas Alzheimer’s Research Consortium project. Patients: We analyzed serum protein-based multiplex biomarker data from 197 patients diagnosed with AD and 203 controls. Main Outcome Measure: The total sample was randomized equally into training and test […]

Treatment of vascular risk factors is associated with slower decline in Alzheimer disease

Background: There is growing evidence that vascular risk factors (VRF) contribute to cognitive decline. Whether their treatment can slow down the progression of Alzheimer disease (AD) remains unsettled. The aim of this observational study was to evaluate whether the treatment of VRF is associated with a slower cognitive decline in patients who have AD without […]

Use of anticholinergics and the risk of cognitive impairment in an African American population

Background: Anticholinergic properties of certain medications often go unrecognized, and are frequently used by the elderly population. Few studies have yet defined the long-term impact of these medications on the incidence of cognitive impairment. Methods: We report a 6-year longitudinal, observational study, evaluating 1,652 community-dwelling African American subjects over the age of 70 years who […]

The effect of a pre- and post-operative orthogeriatric service on cognitive function in patients with hip fracture. The protocol of the Oslo Orthogeriatrics Trial

Background: Hip fractures mainly affect older people. It is associated with high morbidity and mortality, and in particular a high frequency of delirium. Incident delirium following hip fracture is associated with an increased risk of dementia in the following months, but it is still not firmly established whether this is an association or a causal […]

Increased cerebral metabolism after 1 year of deep brain stimulation in Alzheimer disease

Background: The importance of developing unique, neural circuitry-based treatments for the cognitive and neuropsychiatric symptoms of Alzheimer disease (AD) was the impetus for a phase I study of deep brain stimulation (DBS) in patients with AD that targeted the fornix.; Objective: To test the hypotheses that DBS would increase cerebral glucose metabolism in cortical and […]

Effects of n-3 fatty acids, EPA v. DHA, on depressive symptoms, quality of life, memory and executive function in older adults with mild cognitive impairment: a 6-month randomised controlled trial

Depressive symptoms may increase the risk of progressing from mild cognitive impairment (MCI) to dementia. Consumption of n-3 PUFA may alleviate both cognitive decline and depression. The aim of the present study was to investigate the benefits of supplementing a diet with n-3 PUFA, DHA and EPA, for depressive symptoms, quality of life (QOL) and […]

DNA methylation and cognitive functioning in healthy older adults

Long-term supplementation with folic acid may improve cognitive performance in older individuals. The relationship between folate status and cognitive performance might be mediated by changes in methylation capacity, as methylation reactions are important for normal functioning of the brain. Although aberrant DNA methylation has been implicated in neurodevelopmental disorders, the relationship between DNA methylation status […]

Treatment of dementia patients with fracture of the proximal femur in a specialized geriatric care unit compared to conventional geriatric care

To prove the efficiency of a specialized geriatric ward (cognitive geriatric unit, CGU) for patients with a fracture of the proximal femur and additional dementia, we conducted a matched-pair analysis comparing 96 patients with fracture of the proximal femur and additional dementia matched for age, sex, surgical treatment and the degree of cognitive impairment by […]

Effectiveness of a condensed protocol for disclosing APOE genotype and providing risk education for Alzheimer disease

Purpose: Brief, effective models of patient genetic education are needed for common, complex diseases. Using Alzheimer disease as a model, we compared participants’ risk knowledge and recall in extended versus condensed education protocols.; Methods: A four-site randomized clinical trial enrolled 280 first-degree relatives of individuals with Alzheimer disease (mean age = 58 years, 71% female); […]
