Hand motor activity, cognition, mood, and the rest-activity rhythm in dementia: a clustered RCT

Background: Physical activity such as walking may exert a positive impact on cognition and behaviour in older persons with dementia, but due to the frailty of the population it may be worthwhile to consider other motor activities as well.; Objective: Examining the effects of hand motor activity on cognition, mood and the rest-activity rhythm in […]

The influence of aquariums on weight in individuals with dementia

This study assessed whether individuals with dementia who observe aquariums increase the amount of food they consume and maintain body weight. The sample included 70 residents in dementia units within 3 extended care facilities in 2 states. The intervention included the introduction of an aquarium into each common dining area. A total increase of 196.9 […]

Effect of vitamin E and memantine on functional decline in Alzheimer disease: the TEAM-AD VA cooperative randomized trial

Importance: Although vitamin E and memantine have been shown to have beneficial effects in moderately severe Alzheimer disease (AD), evidence is limited in mild to moderate AD.; Objective: To determine if vitamin E (alpha tocopherol), memantine, or both slow progression of mild to moderate AD in patients taking an acetylcholinesterase inhibitor.; Design, Setting, and Participants: […]

Cost evaluation of a coordinated care management intervention for dementia

Objective: To calculate intervention costs and the potential cost offset of a care management intervention that substantially improved the quality of dementia care.; Study Design: From both a payer perspective and a social planner perspective, we analyzed data from a cluster randomized controlled trial (RCT) evaluating this intervention versus usual care. The RCT included 408 […]

Comparative analysis of two musical genres within a multisensory environmental intervention

Purpose: The purpose of this study was to determine if there were any differences in the behavioral responses of persons with dementia while listening to nonreligious and religious music within a multisensory environment.; Research Design: A within-subjects, repeated measures design was used.; Method: Participants were exposed to both musical genres during multiple sessions over a […]

Learning in Alzheimer’s disease is facilitated by social interaction

Seminal work in Gary Van Hoesen’s laboratory at Iowa in the early 1980s established that the hallmark neuropathology of Alzheimer’s disease (AD; neurofibrillary tangles) had its first foothold in specific parts of the hippocampal formation and entorhinal cortex, effectively isolating the hippocampus from much of its input and output and causing the distinctive impairment of […]

“Learning to become a family caregiver” efficacy of an intervention program for caregivers following diagnosis of dementia in a relative

Purpose: The purpose of this experimental study was to test the efficacy of a psychoeducational individual program conceived to facilitate transition to the caregiver role following diagnosis of Alzheimer disease in a relative.; Design and Methods: Caregivers were recruited in memory clinics and randomized to an experimental group (n = 62) or a control group […]

Association between chemotherapy and cognitive impairments in a large cohort of patients with colorectal cancer

No population-based study has been conducted on the relationship between chemotherapy and the risk of cognitive impairments in patients with colorectal cancer. This study aimed to determine this association in a large population-based cohort of patients. We studied 72,374 men and women who were diagnosed with stages I-III colorectal cancer at age ≥ 65 years […]

A phase 3 trial of semagacestat for treatment of Alzheimer’s disease

Background: Alzheimer’s disease is characterized by the presence of cortical amyloid-beta (Aβ) protein plaques, which result from the sequential action of β-secretase and γ-secretase on amyloid precursor protein. Semagacestat is a small-molecule γ-secretase inhibitor that was developed as a potential treatment for Alzheimer’s disease.; Methods: We conducted a double-blind, placebo-controlled trial in which 1537 patients […]

Effects of multicomponent exercise on spatial-temporal gait parameters among the elderly with amnestic mild cognitive impairment (aMCI): preliminary results from a randomized controlled trial (RCT)

Exercise training has been shown to increase physical function in the elderly. However, the effects of exercise on elderly individuals with amnestic aMCI are unclear. The aim of this RCT was to investigate the effect of multicomponent exercise on gait in the elderly. Fifty elderly individuals with aMCI (age: 65-92 years) participated in the study […]
