Creatine supplementation has been reported to improve certain aspects of cognitive and psychomotor function in older individuals and in young subjects following 24 and 36 h of sleep deprivation. However, the effects of creatine supplementation on cognitive processing and psychomotor performance in non-sleep deprived young adults have not been assessed with a comprehensive battery of neurocognit...

Introduction: Psychomotor performance task is used to assess the arousal and cognitive functions of the central nervous system. Alternatively, human visual working memory reflects the capability of the individual’s short-term memory. Psycho-mental stimuli are linked to the stimulation of Malondialdehyde (MDA) formations. Citicoline is a nootropic nucleotide agent with a favorable effect on the ...

BACKGROUND The long-term course of cognitive impairments secondary to cardiovascular disease (CVD) is unclear. In this study, we prospectively investigated the temporal pattern, rate and hierarchy of cognitive decline attributable to CVD--a risk factor for the development of vascular cognitive impairment (VCI)--and examined the influence of cardiac surgery and heart failure on cognitive decline...

Recent researchers have shown that high levels of background noise have a detrimental effect on students’ abilities to perform learning tasks. Daniels (1985), Jewell (1977, 1978), and HambrickDixon found that high noise levels produced a detrimental effect on students’ abilities to perform cognitive or psychomotor skills. Jewel1 (1977, 1978) also discovered that students exposed to higher level...

BACKGROUND Diffusion tensor imaging (DTI) has revealed microstructural aspects of adolescent brain development, the cognitive correlates of which remain relatively uncharacterized. METHODS DTI was used to assess white matter microstructure in 18 typically developing adolescents (ages 16-18). Fractional anisotropy (FA) and mean diffusion (MD) were evaluated within the splenium and body of the ...

reaction time (rt) is one of the psychomotor skills that determine athletes’ results and also in daily life. rt effective factors are divided into inherent (genetic) and environmental. among those factors, psychological factors and mental abilities are more important due to the cognitive nature of rt. the aim of this research was to study the relationship between rt, anxiety and iq of athletes ...

Deficits in specific cognitive and psychomotor capacities, such as attention, reaction time, memory, and hand-eye coordination ability are associated with increased crash risk, especially among older drivers (e.g., Anstey et al., 2005). Higher-order cognitive processes are also closely linked with hazard perception skills (e.g., Groeger, 2000). Employing a large professional driver sample, this...

Tests made of the sensory-perceptual, cognitive, and psychomotor abilities of untreated young patients with essential hypertension have revealed a pattern suggesting a slight functional impairment of the central nervous system. Reduced performance was most marked for those tasks requiring speed and psychomotor coordination, particularly when the behaviors observed were self-initiated. Lowered s...
