Longitudinal analysis of differential effects on agitation of a therapeutic wander garden for dementia patients based on ambulation ability
A growth model within the framework of hierarchical linear modeling was used to assess the impact of visiting a wander garden on monthly agitation levels of a group of elderly veterans diagnosed with dementia, with attention to their ambulatory ability. A sample of 34 veterans residing in a locked ward in a dementia unit was […]

Thyroid medication use and subsequent development of dementia of the Alzheimer type
Associations between medication use and the development of Alzheimer disease have been investigated since the late 1900s. Thyroid hormone supplementation is rarely a studied medication class in this area of research. We examined data from participants enrolled in longitudinal studies at the Washington University Alzheimer’s Disease Research Center for associations between thyroid disease, thyroid hormone […]

Improving decision‐making for feeding options in advanced dementia: A randomized, controlled trial
Objectives: To test whether a decision aid improves quality of decision‐making about feeding options in advanced dementia. Design: Cluster randomized controlled trial. Setting: Twenty‐four nursing homes in North Carolina. Participants: Residents with advanced dementia and feeding problems and their surrogates. Intervention: Intervention surrogates received an audio or print decision aid on feeding options in advanced […]

Utility of combinations of biomarkers, cognitive markers, and risk factors to predict conversion from mild cognitive impairment to Alzheimer disease in patients in the Alzheimer’s Disease Neuroimaging Initiative
Context: Biomarkers have become increasingly important in understanding neurodegenerative processes associated with Alzheimer disease. Markers include regional brain volumes, cerebrospinal fluid measures of pathological Aβ1-42 and total tau, cognitive measures, and individual risk factors. Objective: To determine the discriminative utility of different classes of biomarkers and cognitive markers by examining their ability to predict a […]

A 25-week, open-label trial investigating rivastigmine transdermal patches with concomitant memantine in mild-to-moderate Alzheimer disease: A post hoc analysis
Objective: To investigate the tolerability and efficacy of the rivastigmine transdermal patch in patients with mild-to-moderate Alzheimer’s disease receiving concomitant memantine. Research design and methods: Post hoc analysis of a 25-week, randomized, prospective, open-label, parallel-group study. Patients receiving donepezil were switched to rivastigmine patches (4.6 mg/24 h) immediately or following a 7-day withdrawal for 4 […]

The Computerized Self Test (CST): An interactive, internet accessible cognitive screening test for dementia
The computer self test (CST) is an interactive, internet-based instrument designed to assess functional cognitive domains impaired by Alzheimer’s disease (AD) and mild cognitive impairment (MCI). This study consisted of 215 total subjects with a mean age of 75.24. The 84 cognitively impaired patients (excluding patients diagnosed as MCI) met all criteria set forth by […]

Effects of an interactive video game (Nintendo WiiTM) on older women with mild cognitive impairment
Older adults with a cognitive impairment in residential care settings are often found to be inactive throughout the day. Participation in video games holds promise for these individuals; however, effects of video games played by older adults have not been studied consistently and the few studies conducted have yielded mixed results. The purpose of this […]

Personal digital assistants as point-of-care tools in long-term care facilities: A pilot study
This study used both survey and interview questionnaires. It was designed to assess the feasibility, usability, and utility of two point-of- care tools especially prepared with information relevant for dementia care by staff nurses in a small, a medium-sized, and a large nursing home in Florida. Twenty-five LPN or RN nurses were recruited for the […]

Behavioural abnormalities associated with rapid deterioration of language functions in semantic dementia respond to sertraline
Frontotemporal dementia (FTD) consists of three main clinical syndromes: (1) frontal variant FTD presenting predominantly with behavioral abnormalities, (2) semantic dementia presenting with fluent aphasic deficits and (3) primary progressive aphasia presenting with non-fluent aphasic deficits. We have observed that significant behavioral problems may occur in some patients with semantic dementia when both comprehension and […]

Acetylcholinesterase inhibitor treatment is associated with relatively slow cognitive decline in patients with Alzheimer’s disease and AD + DLB
Dementia can be caused by different diseases including Alzheimer’s disease (AD), dementia with Lewy bodies (DLB), or both (AD + DLB). University of Kentucky AD Center pathologically-diagnosed AD and AD + DLB cases were evaluated who had three or more longitudinal antemortem mental status examinations (n = 156). Patients with important concomitant pathology (n = […]
