Previous research showed that failure primes in academic learning contexts can impair the performance of both older school children and college students. The present research tested the effect of failure priming on cognitive and motor performance in elementary school children. We hypothesized that children incidentally confronted with a cue previously learned to indicate failure would perform w...

Heart Failure is a clinical syndrome prevalent throughout the world and a major contribution to mortality of cardiac patients in Brazil. In addition, this pathology is strongly related to cerebral dysfunction, with a high prevalence of cognitive impairment. Many mechanisms may be related to cognitive loss, such as cerebral hypoperfusion, atrophy and loss of gray matter of the brain, and dysfunc...

Background. The internet offers a potential for improving patient knowledge, and e-mail may be used in patient communication with providers. However, barriers to internet and e-mail use, such as low health literacy and cognitive impairment, may prevent patients from using technological resources. Purpose. We investigated whether health literacy, heart failure knowledge, and cognitive function w...

BACKGROUND Cheyne-Stokes respiration disrupts sleep, leading to daytime somnolence and cognitive impairment. It is also an independent marker of increased mortality in heart failure. This study evaluated the effectiveness of oxygen therapy for Cheyne-Stokes respiration in heart failure. METHODS Eleven patients with stable heart failure and Cheyne-Stokes breathing were studies. Oxygen and air ...

OBJECTIVES To document the degree of cognitive impairment in stable heart failure, and to determine its relation to the presence of Cheyne-Stokes respiration during sleep. SUBJECTS 104 heart failure patients and 21 healthy normal volunteers. METHODS Overnight oximetry was used (previously validated as a screening tool for Cheyne-Stokes respiration in heart failure). Cognitive function was a...
