In this study, we first define the uncertain linguistic Choquet averaging (ULCA) operator and the generalized Shapley uncertain linguistic Choquet averaging (GS-ULCA) operator. Especially, the GS-ULCA operator does not only globally consider the importance of the elements and their ordered positions, but also overall reflect the correlations among them and their ordered positions. Meantime, som...

OBJECTIVE To examine diverse nonmotor neurobehavioral impairments (NBIs) that impact activities of daily living (ADL) task performance and to verify if such impairments can be viewed as one dimension when evaluated in an ecologically-relevant context. METHODS Rasch analysis was performed on data from 206 individuals diagnosed with dementia or cerebral vascular accident (CVA) who had been scor...

BACKGROUND Testing of orientation to time is an important part of mental status examination. The validity of errors in different aspects of temporal orientation was examined in older hospital patients as a guide to the presence of dementia or delirium and as a measure of the severity of dementia, as defined by the Global Deterioration Scale. METHODS Inpatients and outpatients attending an acu...

This study evaluates three versions of the Wayfinding Effectiveness Scale (WES), developed to differentiate problems of wayfinding and wandering behavior of community-residing elders with dementia (EWD), in 266 dyads (EWD and caregiver) recruited from Alzheimer's Association chapters. Factor analyses yield a five-factor solution (explained variance = 62.6%): complex wayfinding goals, analytic s...

Driving is a multifactorial behaviour drawing on multiple cognitive, sensory, and physical systems. Dementia is a progressive and degenerative neurological condition that impacts the cognitive processes necessary for safe driving. While a number of studies have examined driving among individuals with Alzheimer's disease, less is known about the impact of Dementia with Lewy Bodies (DLB) on drivi...

BACKGROUND AND PURPOSE Poststroke cognitive impairment is frequent. There are, however, few longitudinal studies examining delayed changes in poststroke cognition. METHODS As part of a longitudinal study of incident dementia after stroke, 115 older stroke survivors (>75 years of age) without dementia were evaluated at 3 and 15 months with a detailed neuropsychological evaluation (including me...
