OBJECTIVES To evaluate the performance of a one-minute screening test measured against a validated 10-minute screening test for mild cognitive impairment (MCI) in detecting CI in patients aged > or = 65 years with two or more vascular risk factors (VRF). METHODS Patients (n=1523) aged 65 years or older without documented CI symptoms or dementia with two or more VRF participated in this study ...

PURPOSE The purpose of this study was to research the use of near-infrared spectroscopy (NIRS) on the neurocognitive functions in the patients undergoing coronary artery bypass grafting (CABG) with asymptomatic carotid artery disease. METHODS The study design was carried out with the participation of 79 patients in a prospective, randomized and double blind control method. The patients were s...

Background: Cognitive impairment is prevalent in Parkinson's disease (PD), affecting 15-20% of patients at diagnosis. α-synuclein expression and genetic polymorphisms of Apolipoprotein E (ApoE) have been associated with the presence of cognitive impairment in PD although data have been inconsistent. Objectives: To determine the prevalence of cognitive impairment in patients with PD using Montre...

This article presents a middleware architecture for the development and deployment of context-aware collaborative applications for mobile users. The architecture, named Mobile Collaboration Architecture MoCA comprises client and server APIs, a set of core services for registering applications, monitoring and inferring the execution context of mobile devices, and an object-oriented framework for...

Despite widespread use, there have been few investigations into the neuroanatomical correlates of the Montreal Cognitive Assessment (MoCA). In a sample of 138 consecutive patients presenting with cognitive complaints, we report significant correlations between lower MoCA memory scores and smaller hippocampal volumes (r = 0.36-0.41, p < 0.001). We also report that the newly devised memory index ...

Introduction Cognitive and gait deficits are common symptoms in Parkinson's disease (PD). Motor-cognitive dual tasks (DTs) are used to explore the interplay between gait and cognition. However, it is unclear if DT gait performance is indicative for cognitive impairment. Therefore, the aim of this study was to investigate if cognitive deficits are reflected by DT costs of spatiotemporal gait par...

BACKGROUND The dual-task performance is associated with the functionality of the elderly and it becomes more complex with age. OBJECTIVE To investigate the relationship between the Timed Up and Go dual task (TUG-DT) and cognitive tests among elderly participants who exercise regularly. METHOD This study examined 98 non-institutionalized people over 60 years old who exercised regularly. Part...
