OBJECTIVE To assess the relation between the evolution of cognitive performance and the prognosis of elderly patients after compensation of advanced heart failure. METHODS Thirty-one patients older than 64 (68 +/- 7) years and admitted with New York Heart Association class IV heart failure and ejection fraction = 0.45 (0.38 +/- 0.06) were consecutively selected. They underwent cognitive tests...

The objective of this study was to establish a rodent model of vascular dementia that showed long-term cognitive and neuropsychological deficits, and to correlate those behavioral deficits with the patterns of ischemic lesions, thus providing a platform for future testing of potential therapeutic agents. In Mongolian gerbils, either 5-minute single bilateral common carotid artery occlusion (SBC...

Cognitive operations are supported by dynamically reconfiguring neural systems that integrate processing components widely distributed throughout the brain. The inter-neuronal connections that constitute these systems are powerfully shaped by environmental input. We evaluated the ability of computer-presented brain training games done in school to harness this neuroplastic potential and improve...

The capability of detecting symptoms hypoxia (i.e., reduced oxygen) and other cognitive impairments in-flight with wearable sensors machine learning based algorithms will benefit the aviation community by saving lives preventing mishaps. In this study, knowledge discovery processes were implemented to build classification models predict from wearable, dry-EEG sensor data collected 85 participan...

Abstract BACKGROUND Mild cognitive impairment (MCI) commonly occurs in primary CNS tumor patients (PCTP). Our group and others have reported on the Montreal Cognitive Assessment (MoCA) as an MCI screening tool. Several abbreviated MoCA protocols been developed for telehealth administration other neurological diseases, with varied literature scoring clinical utility. We compared Full 5-minute sc...

BACKGROUND AND PURPOSE The interpretation of cognitive data in many experimental stroke studies is problematic because middle cerebral artery occlusion (MCAO) is associated with sensorimotor alterations that may become confounding factors in cognitive testing. The purpose of the current study was to determine if it is possible to measure MCAO-induced cognitive deficits by using short durations ...
