Abstract

Background: Memory acts as a storage mechanism for obtained knowledge which can be remembered later. Especially for students who spend most of their time to study, short-term memory is often being used before the information consolidated to long-term memory.The past researches have indicated that individual’s attention level whom receive multisensory stimuli will be higher than those who receive unisensory stimulus. In which attenion is closely related to memory, thus stimuli can affect individual’s short-term memory performance Method: This present study is an analytic-experimental study with posttest only design. Short-term memory performance is measured by Digit Span test. Each of the three groups were given three different stimuli namely auditory, visual, and audiovisual. The score would be analyze using one-way ANOVA statistical test. In which the p-value ≤ 0,05 is considered significant. Results: There is a significant difference of the Digit Span total score among three groups with different stimuli. The p-value is 0.003 on ANOVA test. On Bonferroni statistical test, the audiovisual group obtained the highest score with p-value 0.016 compared to the auditory group and 0.005 compared to the visual group. Discussion: Two stimuli of information provided a better impact on short-term memory than giving one stimulus. This occurs because of the integration in the parietal-temporal-occipital association cortex to two or more stimuli that are given simultaneously. Processing the input received by the brain becomes easier and a more complete memory output is obtained. Conclusion: There is a significant result on this study by giving different type of stimuli towards short-term memory performance

Abstract

Chronic kidney disease (CKD) is an independent risk factor for cognitive impairment in all domains, especially delayed memory and executive function. The purpose of this study was to determine the correlation between chronic kidney disease severity and cognitive function. This study used a cross-sectional design in stage III, IV, and V CKD patients in the Nephrology Polyclinic of Haji Adam Malik Central General Hospital. Cognitive function tests were performed using the Montreal Cognitive Assessment (MoCA INA), digit span, and Trail Making Test A & B. The Spearman test was used to analyze the correlation between CKD severity and cognitive function. This study involved 45 chronic kidney disease patients consisting of 28 (62.2%) males and 17 (37.8%) females with a mean age of 49.67±12.18 years. The results of statistical analysis showed that there was a significant positive correlation between CKD on the MoCA-INA examination (r=0.618, p=<0.001), FDS (r=0.414, p=0.005), there was a significant negative correlation on the TMT A time examination (r=-0.425, p=0.004), TMT A error (r=-0.497, p=0.001), TMT B time (r=-0.618, p=<0.001), TMT B error (r=-0.370, p=0.012). The results of this study prove a significant correlation between the severity of CKD and cognitive function.

Abstract

The last few decades have seen an increase in the number of elderly populations around the world. One consequence of an aging population is an increased incidence of impaired cognitive function. Serotonin, or 5-hydroxytryptamine (5-HT), is found to be involved in many physiological or pathophysiological processes including cognitive function. Alterations in serotonin (5-HT) function have been hypothesized to underlie a range of physiological, emotional, and cognitive changes in eldery. This paper provide reviews and references that a serotonin plays a role in the cognitive function of the elderly.
